<p>First off, I&#8217;d like to make sure you know what you&#8217;re going to get from  this review. This isn&#8217;t going to be your run of the mill motherboard  review where I ramble about the number of USB and SATA ports and run  meaningless tests comparing motherboards and drawing conclusions from  the tiny differences between boards. First I&#8217;m going to briefly discuss  the features and layout of the board keeping in mind my point of view as  an overclocker. Next I&#8217;ll show some results with the board and discuss  how they compare to competing boards with a focus on clock for clock  efficiency in the benchmarks used by HWBot.org. Additionally I&#8217;ll be  discussing the overall experience or using the board including a few  subzero sessions.</p>
<p>Gigabyte&#8217;s X58A UD9 is many things, it&#8217;s Gigabyte’s flagship X58 based  board, it supports Quad-SLI and CrossfireX, and has USB 3.0 and SATA 6.  Oh, by the way, it&#8217;s $700 on Newegg. To be honest, I have trouble  imagining a single socket X58 board that could possibly be worth $700  when the next highest priced board is right around $500 and has a  similar feature set with the exception of USB 3.0 and SATA 6. Are USB  3.0 and SATA really worth $200? They certainly aren&#8217;t to me, and I  suspect that many others feel similarly.</p>
<p><strong><span style="font-size: small">Features</span></strong><br />
As this is Gigabyte&#8217;s flagship Intel based board it has just about every  feature you could imagine for a motherboard. USB 3.0 as well as SATA 6  and a pair of eSATA ports are included to cover all of your current and  future storage needs.</p>
<p><img src="http://img696.imageshack.us/img696/769/dsc4497.jpg" border="0" alt="" /></p>
<p>The rear I/O Pannel has everything that is expected on a high-end board.  Personally, I appreciated the eSATA/USB ports as they allowed greater  flexibility. At this point, having a pair of PS2 ports seems a bit over  the top and I would prefer to see that reduced down to one that worked  for either keyboard or mouse.</p>
<p><img src="http://img6.imageshack.us/img6/8380/dsc4490z.jpg" border="0" alt="" /></p>
<p>Additionally, the board includes the Nvidia chips &#8220;necessary&#8221; to enable  Quad SLI. In order to make this as easy as possible the board includes a  full 7 PCI-Express 16x slots.</p>
<p><img src="http://img205.imageshack.us/img205/7441/dsc4488z.jpg" border="0" alt="" /></p>
<p>While very handy for running multiple GPUs, this is annoying for people  who would like to use a PCI post card or sound card. Also included on  the board is a two digit POST code display to make diagnosing boot  issues easier which is critical when overclocking.</p>
<p><img src="http://img686.imageshack.us/img686/255/dsc4515v.jpg" border="0" alt="" /></p>
<p>If you are someone who cares about all the minor features of the board  I&#8217;ll point you over to Gigabyte&#8217;s product page for the board as it does a  solid job of discussing the boards features in more detail.</p>
<p><strong><span style="font-size: small">Layout</span></strong><br />
First the obvious, the UD9 is larger than your typical motherboard; it  is both taller and wider. The width really isn&#8217;t much of an issue, as it  will fit comfortably in to any case which accepts E-ATX motherboards.  The height is more of an issue as it prevents the board from fitting  into cases that have only 7 expansion slots.  The UD9 also has two 8-pin  EPS12V connectors to ensure that the CPU provided all the power is  needs. While I do appreciate this, the placement is less than ideal as  it is a bit of hassle to remove the power supply connectors once they  have been connected.</p>
<p><img src="http://img156.imageshack.us/img156/9083/dsc4502.jpg" border="0" alt="" /></p>
<p>Right above the PCI-Express slots and at the bottom of the board, a pair  of 4-pin drive connectors are included to guarantee that there is  enough power for the board when running multi-GPU setups.</p>
<p><img src="http://img263.imageshack.us/img263/1600/dsc4463.jpg" border="0" alt="" /></p>
<p>Similar to other high-end boards the UD9 includes both power and reset  buttons on board to make using the board on an open test bench somewhat  easier. While I can&#8217;t really complain about this, it did bug me a bit  during testing, the size difference between the power and reset buttons  is a bit jarring and does make the reset button a bit hard to hit  without looking for it.</p>
<p><img src="http://img265.imageshack.us/img265/2462/dsc4530i.jpg" border="0" alt="" /></p>
<p>Additionally, Gigabyte includes an extra heatsink that screws onto the  top of the northbridge heatsink to provide extra northbridge cooling for  those that will be sticking to air cooling for the board. Also included  is a waterblock that cools the northbridge and allows anyone who  already has a water cooling loop to cool the northbridge easily. All of  this extra cooling that is included would be great if it weren’t for one  thing. Both the waterblock and the extra heatsink attach to a piece of  metal that attaches to fins which attach to another metal base which  finally contacts the X58 northbridge. Does anyone else see the problem  here? There are Fins between the northbridge and the waterblock.</p>
<p><img src="http://img405.imageshack.us/img405/4906/dsc4518k.jpg" border="0" alt="" /></p>
<p>Fins are meant to dissipate heat not transfer it, as a result both the  extra air heatsink and the waterblock have little effect on northbridge  temperatures. After seeing this I proceeded to do all of my testing with  either the waterblock or extra heatsink. Throughout the course of  testing the northbridge temperature never exceeded 45 degrees Celsius,  which is impressively low especially compared to some of the other  high-end X58 based boards. I’m going to sum up the UD9 heatisnk  situation with this, if you find that your having problems with your  northbridge running too hot, odds are, you’re doing something wrong.</p>
<p><img class="aligncenter" src="http://img36.imageshack.us/img36/9184/dsc4474j.jpg" border="0" alt="" /></p>
<p>The CPU socket area is fairly typical, we see Gigabyte&#8217;s 24 phase power  delivery system and well, everything else is fairly typical of X58  boards. The mosfet cooling around the socket is a nice height as is did  not interfere with any of the cooling methods we tested including the  Prolimatech Megahalems and the single stage phase change cooler which  can be tough to mount on some boards.</p>
<p>The one thing I feel is worth mentioning from an overclocking point of  view is that the area around the socket is relatively crowded which  makes insulating the board for subzero runs a bit of a challenge.</p>
<p>Finally, the one thing that I is missing from the board is a set of  voltage measuring points as to be able to measure the actual voltage  that components are receiving. This has become standard on overclocking  oriented boards and I feel that it is a significant omission. Ironically  enough, the lack of measuring points hits especially hard as the  voltage set in BIOS and the actual voltage differed significantly most  of the time. This left me having ask around (thanks Jody) to find  measure points which were fairly inconvenient (behind the CPU socket.)</p>
<p><strong><span style="font-size: small">Test Setup</span></strong></p>
<p><strong>Motherboard:</strong> Gigabyte X58A-UD9<br />
<strong>Processor:</strong> Intel Core i7 980X Retail<br />
<strong>Cooling:</strong> Single stage phase change, Kingpin Cooling F1EE + LN2<br />
<strong>Memory:</strong> Corsair Dominator GT 2000C7<br />
<strong>Video Card:</strong> Gigabyte GTX 480<br />
<strong>Power Supply:</strong> Antec TPQ1200<br />
<strong>Hard Drive:</strong> OCZ Vertex and Agility SSDs</p>
<p>A few notes about the UD9 and its BIOS<br />
When I received the board it had the F1 bios, in this state is couldn&#8217;t  clock memory to save it&#8217;s life, multiple kits, multiple CPUs and it  still would only run 2000 MHz with 8-9-8-x or looser timings.  Thankfully, this issue was fixed in F2 and later BIOSes and is no longer  an issue as the UD9 now nearly identical to other high-end boards in  terms of memory performance.</p>

<p>All of the above results were achieved using the single stage phase  change cooling unit which runs between -30C and -40C depending on the  benchmark. Keeping this in mind, I&#8217;m happy with the results as the  scores are all right around where they should be for a high-end board.  The fact that Gigabyte has manged to keep their efficiency very close to  that of boards that do not have NF200s while having two on board is  impressive in my mind as most boards with NF200s on board take a slight  performance hit in single card tests due to the added latency.</p>
<p><a href="http://img33.imageshack.us/img33/3188/sub75049ud9.png" rel="lightbox[7284]"><img class="aligncenter" style="border: 0pt none" src="http://img33.imageshack.us/img33/3188/sub75049ud9.png" border="0" alt="" width="600" height="610" /></a></p>
<p>Now on to my favorite bench, low clock testing of SuperPi 32M. If I had  to pick an area where the UD9 stood out, this would be it. Throughout  testing, I was able to run 32M with my RTL values at least 1-2 settings  tighter than on the E760 Classified. As a result, the UD9 enjoys a  slight clock for clock advantage over the E760 classified in my testing.  This allowed me to achieve a new personal best for lowest frequency  needed to reach a sub 7 minute 32M run.</p>
<p style="text-align: center"><a href="http://img215.imageshack.us/img215/1738/417kam3.png" target="_blank" rel="lightbox[7284]"><img class="aligncenter" src="http://img227.imageshack.us/img227/4499/417227am3ud9ssthumb.png" border="0" alt="" /></a><br />
<span style="font-size: xx-small">Click for full screenshot</span></p>
<p>This final result required liquid nitrogen cooling to achieve, and while  not the greatest score overall, the clock for clock efficiency  demonstrates what is possible with a better CPU.</p>
<p><img class="aligncenter" src="http://img706.imageshack.us/img706/7772/dsc4450i.jpg" border="0" alt="" /></p>
<p>Overall, the Gigabyte X58A-UD9 proved itself to be a solid, dependable  board that never gave us any problems other than the initial memory  struggles. A solid feature set, combined with well thought out layout  and better efficiency than other boards make for a very respectable  flagship board. Regardless, in good conscience I can&#8217;t recommend it at  the $700 price point it currently occupies. It&#8217;s a great board but even  in my efficiency  oriented mind, the slightly better efficiency isn&#8217;t  worth anywhere near the $200 extra it costs. If Gigabyte can get the  price under control and bring it back into the realm of &#8220;reason&#8221;, say  under $550, the UD9 will prove a very compelling choice for enthusiasts  and overclockers alike.</p>

			<content:encoded><![CDATA[<p>The <a href="http://www.mcmelectronics.com/product/72-7712" target="_blank">72-7712 Digital Thermometer</a> from Tenma Test Equipment is a dual thermocouple meter with internal logging capability, USB output for saving logged data and software up-link.  This unit can become an integral part of a PC testing arsenal by allowing for isolation of case hot spots, heat sink testing and LN2/Dry Ice work. The limitations start to change and the performance bar can be raised when you know where it is hot and where it is not.</p>
<ul>
<li>Compatible with K-, J-, T- and E- thermocouples (others should work but these are the recommended types)</li>
<li>User programmable offsets</li>
<li>Internal memory stores 100 sets of temperature readings that can be transferred to PC software</li>
<li>Data logging software for real time testing (good for working with fan and component placement and viewing their effects in real time)</li>
<li>Ability to export data sets from software in .xls format to do comparative studies and graphing</li>
</ul>
<p>The graph capabilities of the 72-7712 software are not phenomenal, it does however serve the purpose. Though dual software readout (T1 &amp; T2) would be preferred; the logging capacity and decent feature set, as well as an Excel export feature make up for the software weaknesses.</p>

<p style="text-align: left;">Thermal conductivity of the heat sink material is an important factor in air cooling. Copper and aluminum are the most widely used materials in PC HSF (heat sink &amp; fan) construction. The properties of these two materials are critical to proper cooling of the processor.</p>
<p style="text-align: left;">The Chart below shows the thermal conductivity of materials for comparison. The only three that matter for this testing are aluminum, copper and air (water and the other items may be of interest to those who like to get a little wet).</p>
<p style="text-align: left;">
<div class="mceTemp mceIEcenter" style="text-align: left;">
<dl id="attachment_6992" class="wp-caption aligncenter" style="width: 590px;">

<dd class="wp-caption-dd">Fourier&#8217;s Law express conductive heat transfer as q = k A dT / s (1) where q = heat transferred per unit time (W, Btu/hr) A = heat transfer area (m2, ft2) k = thermal conductivity of the material (W/m.K or W/m oC, Btu/(hr oF ft2/ft)) dT = temperature difference across the material (K or oC, oF) s = material thickness (m, ft)</dd>

</div>
<p style="text-align: center;">:<a href="http://www.engineeringtoolbox.com/conductive-heat-transfer-d_428.html">More information about thermal conductivity and conductive heat transfer</a>:</p>
<p style="text-align: left;">Some simple ideas for improving the PC enthusiast experience:</p>
<p><strong>Checking the case for hot spots</strong>.</p>
<p style="text-align: left;">Keeping your entire case as close to ambient is probably the most important thing that can be done to keep the HSF operating at its maximum efficiency. A heat sink can not lower temperatures below case ambient and will usually level out 4-12 degrees centigrade above case ambient no matter how much money is spent on it.</p>
<p style="text-align: left;">By identifying hot spots, proper fan placement can be made. Though these areas may not seem relevant to CPU cooling; they are. Air circulating throughout the case creates eddies, (a current of air running contrary to the main current; <em>especially</em><strong>:</strong> a circular current <strong>:</strong> whirlpool) which in turn, remain hot and by cross circulation make  air circulating around them heat up.</p>
<p style="text-align: left;">Working in a similar fashion to the eddy, dead zones (hot area where there is no mechanical air circulation) may seem harmless, it is critical to circulate or eliminate this air to alleviate convection (heat transfer in a gas by the circulation of currents from one region to another). For dead zones a fan may not be an option and directed air may be needed. If directed air is not possible then closing in/sectioning off this area may be the only option.</p>

<p>Knowing where the hot areas of the case are allows for fixes that otherwise would not be possible.</p>
<p style="text-align: left;"><strong>Testing for efficiency.</strong></p>
<p style="text-align: left;">Methodology: Air can only dissipate a fixed amount of heat due to its low thermal conductivity. Having a material of higher thermal conductivity does not always mean better temperatures, but it does allow a potential for lower temperatures, depending on other contributing factors. Testing the two most common heat sink materials to see these differences helps gain an understanding of what the conductivity numbers really mean.</p>
<p style="text-align: left;">Copper and Aluminum heat sinks tested for conductivity.</p>
<p style="text-align: left;">Copper; 56.8 seconds to reach maximum <span style="color: #ff0000;">efficiency</span> with a variance of 3.9 degrees centigrade</p>
<p style="text-align: left;">Aluminum 59.8 seconds to reach maximum <span style="color: #ff0000;">efficiency</span> with a variance of 7.9 degrees centigrade</p>
<p style="text-align: left;"><span style="color: #ff0000;">This is the point where temperatures stabilize and heat is dispersed through natural convection. <strong>This is not a scientific test as the blocks were not exactly the same and some variables were omitted.</strong></span> What it does show is that copper will transfer heat faster and more evenly.</p>

<p style="text-align: center;">
<p style="text-align: left;">A two minute test of both materials (copper and aluminum) showed a 3.7 degree centigrade variance, copper being hotter (this is good, it means it will draw that much more heat to be dissipated). It must be taken into consideration that these heat sinks did not have a fan and the variance would have been lower during operation.</p>

<p>If the HSF is not equalizing temperatures within a reasonable variance or running 10+ degrees above ambient case temperature (check the temperature at the intake area of the HSF to eliminate the possibility of a hot spot causing the problem) then a re-seat of the HSF may be needed and possibly a replacement HSF of higher quality may be in order.</p>
<p>Using information gathered with a good temperature meter will help guide the process of lowering case temperatures and in turn allow for a cooler processor, memory and hard disk drive.</p>

<p><strong>Conclusion</strong></p>
<p>Using a dual probe temperature meter with capabilities comparable to the 72-7712 is a definite step up from the volt meter type single probe units that were used in the past. With the data logging capabilities and other features available with this unit it is much easier to maximize case cooling and potentially gain a few hundred MHz from a heat limited overclock.</p>
<p>With acceptable quality, useful software and features the 72-7712 makes an excellent addition to the tool box of the overclocker or small PC mod shop.</p>

			<content:encoded><![CDATA[<p align=center><img class="noborder" src="http://www.techreaction.net/wp-content/uploads/2009/07/3oh6_0006_01_banner-1.jpg"></p>
<p align="justify">The idea of a low clock challenge is to provide a playing field for benchmarkers to prove their tweaking skills in a given benchmark.  Setting specific limitations constructs the playing field and opens the doors to a lot of people to compete that might not have the newest or best hardware that a wide open competition would require.  <a href="http://www.overclockaholics.com/">Overclockaholics.com</a> recently had a low clock 3Dmark 01 challenge which locked CPU clocks to 4.2GHz and limited Nature Frames Per Second to 1200FPS for single card or 1400FPS for dual card entries.  These two simple limitations really setup an array of possible winning combinations that require tweaking skills at both the software and hardware level.</p>
<p align="justify">Needing a bit of a break from pounding my head against the wall with a memory review, I took a couple days to get back in the 3DMark 01 tweaking seat &#8211; which hasn&#8217;t been sat in for some time &#8211; and tried my hand at the <a href="http://www.overclockaholics.com">Overclockaholics.com</a> 3DMark 01 Low Clock Challenge.  Here is my story of how I came to winning the single card category last weekend.</p>
<p align="center"><a href="http://www.techreaction.net/wp-content/uploads/2009/07/3oh6_0006_prep-1.jpg" rel="lightbox[1434]"><img src="http://www.techreaction.net/wp-content/uploads/2009/07/3oh6_0006_prep-1sm.jpg"></a></p>
<p align="justify">There are two primary platforms that can be competitive in this type of challenge, using an Intel C2D on the 775 platform or the slightly less potent Intel i7 socket 1366 platform.  The reason i7 is actually a worse a platform for 3DMark 01 is the fact that the Nature benchmark scores are terrible on the i7 platform at 4.2GHz compared to C2D.  You will soon find out that I had plans to take care of that.  Essentially though, I had both platforms setup ready to rock but my goal was to be competitive with the i7 platform using whatever means necessary.  I began preliminary testing on the Intel i7/X58 platform with phase cooling on the CPU.  The need for sub-zero cooling on the CPU will also be explained shortly.</p>
<p align="center"><a href="http://www.techreaction.net/wp-content/uploads/2009/07/88794.png" rel="lightbox[1434]"><img src="http://www.techreaction.net/wp-content/uploads/2009/07/88794sm.png"></a></p>
<p align="justify">With the GPU on air, it was apparent that being competitive just wasn&#8217;t going to be possible.  At a minimum, 90K was going to be required to win this thing, at this point in the weekend, I think the top score posted for single card was around 89.5K already.  Even with the CPU under sub-zero conditions allowing for a very nice uncore clock &#8211; which helps 01 scores tremendously &#8211; the Nature FPS were just too low to compete.  That is when the big guns were brought out to help the little GTX260 play with the C2D boys.</p>

<p align="justify">A little rubber eraser, 1 <a href="http://www.kingpincooling.com">KingpinCooling.com</a> Tek9 4.0 Slim, a 50K ohm variable resistor, a couple shop towels, and this setup was ready to rock 01&#8217;s world.  The variable resistor was the only mod done to the card which was done to bypass OCP.  Other than that, this is just a straight up Gigabyte GTX260 216SP video card.  Here is a complete list of the hardware used for the rest of the competition.</p>

<p align="justify">Over the course of two six hour sessions, this system was beaten, abused, and downright throttled.  The GTX260 nicely surprised me willing to run through Nature at -140C.  Normally these GPU&#8217;s will cold bug well before that without a special BIOS so either these cards had that special BIOS, or this card is just a freak of nature.  Either way, the GPU clocks definitely helped the score and took the single card results for the competition to the next level.  Here are a couple photos of the two bench sessions.</p>
<p align="center"><a href="http://www.techreaction.net/wp-content/uploads/2009/07/3oh6_0006_setup-1.jpg" rel="lightbox[1434]"><img src="http://www.techreaction.net/wp-content/uploads/2009/07/3oh6_0006_setup-1.jpg" width="293" height="165"></a> <a href="http://www.techreaction.net/wp-content/uploads/2009/07/3oh6_0006_setup-2.jpg" rel="lightbox[1434]"><img src="http://www.techreaction.net/wp-content/uploads/2009/07/3oh6_0006_setup-2.jpg" width="293" height="165"></a></p>
<p align="justify">Most of the benching was done with the GPU at -120C and the CPU at -30C ~ -35C.  The digital multi-meter is showing the resistance across the OCP mod which I set to 13.33K Ω.  This allowed GPU voltage of 1.25v to be used at clocks in excess of 1000MHz.  For the suite of benchmarks, GPU clocks were set to 1026MHz with shaders running at 2052MHz.  The GPU memory clocks were most stable at 1215MHz but could creep close to 1300MHz.  For Nature however, the GPU clocks were set as they are in the screen shot below, 1080/2160/1215.  Here is the screen shot of my best &#8211; and winning &#8211; single card result.</p>

<p align="justify">Obviously this isn&#8217;t even the best this setup could pull off at 4.2GHz because Nature is far from maxed out.  If I could get GPU clocks high enough to hit the 1200FPS limit in Nature, the overall score would have been at least 92K.  Either way it didn&#8217;t matter as this was enough to win the competition and take home a very much needed <a href="http://www.kingpincooling.com">KingpinCooling.com</a> F1 EE CPU pot.   I have been benching with a MMouse Rev3 CU pot for so long that the upgrade to one with more mass is guaranteed to help with multi-threaded benchmarks like Vantage and 06 with the i7 processors.  To wrap things up, here are a couple photos of the setup during tear down.  Plenty of snow was produced during the bench session, nothing like winter in July.</p>

<p align="justify">I would like to thank <a href="http://www.overclockaholics.com">Overclockaholics.com</a> for a great contest, the rest of the competitors for pushing me to go LN2 on the GPU, and <a href="http://www.kingpincooling.com">KingpinCooling.com</a> for the prize.  All I can say is that this card is far from done.</p>

			<content:encoded><![CDATA[<p>Between June 26th- 28th I got the great opportunity to go to K|ngp|n&#8217;s lab in Detroit and bench on Liquid Nitrogen, and it was my first time&#8230;  That was after I took a bus trip to get there that was probably 10 times longer than what it would have been if I flew, though then again it wasn&#8217;t 850 USD either.</p>
<p>I arrived mid afternoon Friday and luckily I had no hardware casualties from the trip there, I met everyone when I arrived and it was really cool to meet those that I looked up at for so long.  Vince was benching a killer rig (pics being kept under my hat ) and said after they were done they would get me set up with a rig to learn LN2.  When I was being taught the ins and outs from everyone I was thinking that I had the opportunity to learn using LN2 from some of the best in the business and got a kick out of that. Shamino, K|ngp|n, Gomeler, Gautam, Vapor, 3oh6, Andre Yang, and Philly Boy were on hand with a few others to bench and hang out as well.  I was set up to bench LN2 at a desk and was lucky enough to learn benching the Classified under LN2 by none other than Shamino, and that was a real treat to me.  I was surprised how many Classified motherboards were on hand and then had to remind myself were I was and then it seemed normal. Over the weekend I saw a lot of records set and had a lot of fun -</p>
<p>I took some pics and think typing at 4:42am isn&#8217;t the best for blogging and will let the pics do the rest of the talking for me &#8211; notice how nonchalant Vince is as he fills his dewars LOL</p>
<p>The good photos of me were taken by 3oh6 (an awesome photographer)!</p>

			<content:encoded><![CDATA[<p style="text-align: center;"><a href="http://www.techreaction.net/wp-content/uploads/2009/05/1m.jpg" rel="lightbox[729]"></a>I was recently offered a choice by a certain individual&#8230;&#8230;</p>
<p style="text-align: center;">You take the blue pill and it&#8217;s over, you wake up tomorrow and continue life as you know it and you believe what you want to believe.</p>
<p style="text-align: center;">You take the Green pill and I show you a world you never could have imagined in your wildest dreams where limits and boundaries are meant to be broken.</p>
<p style="text-align: center;">I obviously chose the Green pill <img src='http://www.techreaction.net/wp-includes/images/smilies/icon_wink.gif' alt=';)' class='wp-smiley' /> </p>
<p style="text-align: center;">I will save the long drawn out speech for after the results&#8230;..So lets get right to the results&#8230;.</p>
<p style="text-align: center;">I would like to state that in no way did I push this CPU to the limits in 2D&#8230;.I had tuned my hardware for 100% efficiency prior to the trip to Austin.  I don&#8217;t use software tweaks, its not my thing and quite honestly I really don&#8217;t need them as I&#8217;m a firm believer that hardware tuning is greater than any software tuning can be.</p>
<p style="text-align: center;">
<p style="text-align: center;"><strong>System Configuration:</strong></p>
<p style="text-align: center;">Gigabyte 790FXT-UD5P</p>
<p style="text-align: center;">AMD ??? CPU</p>

<p style="text-align: center;">As always with me, I do not validate single cores, this is a 4 core validation also denoting I could have benched higher had I chosen to.</p>
<p style="text-align: center;"><a href="http://www.techreaction.net/wp-content/uploads/2009/05/cpu-z-validation.jpg" rel="lightbox[729]"><img class="alignnone size-thumbnail wp-image-738" src="http://www.techreaction.net/wp-content/uploads/2009/05/cpu-z-validation-150x150.jpg" alt="cpu-z-validation" width="150" height="150" /></a></p>
<p style="text-align: center;">I ran some 3D with my 2&#215;1GB set.</p>
<p style="text-align: center;"><a href="http://www.techreaction.net/wp-content/uploads/2009/05/2x-4890-2bdlace1.jpg" rel="lightbox[729]"><img class="alignnone size-thumbnail wp-image-741" src="http://www.techreaction.net/wp-content/uploads/2009/05/2x-4890-2bdlace1-150x150.jpg" alt="2x-4890-2bdlace1" width="150" height="150" /></a></p>
<p style="text-align: center;">Not happy with the result and knowing I could squeeze a few more points out, I swapped to my OCZ 2&#215;2GB sticks which I prefer for benching 3D.</p>
<p style="text-align: center;"><a href="http://www.techreaction.net/wp-content/uploads/2009/05/2x4890-wr-animals.jpg" rel="lightbox[729]"><img class="alignnone size-thumbnail wp-image-742" src="http://www.techreaction.net/wp-content/uploads/2009/05/2x4890-wr-animals-150x150.jpg" alt="2x4890-wr-animals" width="150" height="150" /></a></p>
<p style="text-align: center;">All in all I had a great time and would like to take a moment to thank some people.</p>
<p style="text-align: center;">Special thanks goes out to Simon Solotko for being a believer.</p>
<p style="text-align: center;">Special thanks goes out to Vince AKA K|ngp|n.  It was an honor to bench next to you and an honor to use your prototype pot</p>
<p style="text-align: center;">This thing is a beast and is going to make benching LN2 so much more relaxing</p>
<p style="text-align: center;">Special thanks goes out to Aaron Shradin for letting me test the prototype acrylic see through LN2 pot.</p>
<p style="text-align: center;">I think this is the first piece of hardware I have ever used that looks cool and works 100%.</p>
<p style="text-align: center;">I also think this may be one of the best pots ever made in the pound for pound category&#8230;.holding at -190 no load and -189.8 loaded.</p>
<p style="text-align: center;">Special thanks goes out to the rest of the AMD crew who was more than hospitable and helped to make this event possible right down to the engineers.</p>
<p style="text-align: center;">It was an honor to get invited and I truly hope I did not disappoint.</p>
<p style="text-align: center;">For those who may ever get a chance like this themselves, the best advice I can give you is to seize the moment and own it as this opportunity truly only comes once in a lifetime&#8230;</p>
<p style="text-align: center;">

			<content:encoded><![CDATA[<p align="justify">It was almost exactly a month ago that I took the Classified and its 965 occupant over the 5GHz mark and under seven minutes in 32M SuperPi.  Well today, I took the baby nephew of the 965 &#8211; an Intel Core i7 920 &#8211; well over 5GHz and even further below seven minutes in 32M Super Pi.</p>
<p align="justify">The trip started innocently enough with a locally purchased i7 920 sporting the date code 3845B026.  Soon after some quick air testing, however, things took a turn towards the crazy track with the idea to test a theory on whether a colder north bridge would assist with BCLK clocking.  It turns out it didn&#8217;t, but that won&#8217;t prevent me from showing the vacation photos.</p>

<p align="justify">I had simply planned on multiple layers of Armaflex insulation tape for the NB pot but ran into a problem when I realized my roll of Armaflex tape was still making it&#8217;s way back from the GOOC 09 event in California this past weekend&#8230;so I had to improvise.</p>
<p align="center"><a href="http://www.techreaction.net/wp-content/uploads/2009/05/prep-4.jpg" rel="lightbox[488]"><img src="http://www.techreaction.net/wp-content/uploads/2009/05/prep-4.jpg" alt="EVGA X58 3X SLI Classified" title="EVGA X58 3X SLI Classified" width="167" height="250" /></a> <a href="http://www.techreaction.net/wp-content/uploads/2009/05/prep-5.jpg" rel="lightbox[488]"><img src="http://www.techreaction.net/wp-content/uploads/2009/05/prep-5.jpg" alt="EVGA X58 3X SLI Classified" title="EVGA X58 3X SLI Classified" width="167" height="250" /></a></p>
<p align="justify">After some cutting of 1/2&#8243; Armacell sheets, I had a nice little north bridge pot insulation sandwich.  Paired with the mounted MMouse Rev 3 CU pot, I had my twin towers ready to rock.  After looking at the north bridge insulation sandwich for a while, it gave me the craving for a clubhouse, so it was a couple hours and a few pints later that the benching began.

<li type=square>Custom N&#8217;lightnd Windows XP Pro SP3
<li type=square>Corsair HX1000W</ul>
<p></p>
<p align="justify">As mentioned, the cold north bridge didn&#8217;t assist with BCLK at all, as I got the same clocks as previously with the north bridge running at a steady 70C during a previous session.  This wasn&#8217;t much of a surprise to be honest.  At the 250BCLK point, the Classified simply needs fine voltage adjustments to eek the most out of a processor.  It was still fun running the NB at -40C, and it seemed to handle those temps no problem at all.</p>
<p align="center"><a href="http://www.techreaction.net/wp-content/uploads/2009/05/cold-1.jpg" rel="lightbox[488]"><img src="http://www.techreaction.net/wp-content/uploads/2009/05/cold-1.jpg" alt="EVGA X58 3X SLI Classified" title="EVGA X58 3X SLI Classified" width="250" height="141" /></a></p>
<p align="justify">Enough fooling around though, time to look at the results.  First up is the highest BCLK I have reached with this combination so far.  As mentioned, more is definitely possible with proper time put in fine tuning secondary voltages&#8230;but 250+ for validation is still plenty impressive</p>
<p align="center"><a href="http://valid.canardpc.com/show_oc.php?id=558936" alt="Click for 253.36 x 21 = 5320.57MHz CPU-Z Validation" title="Click for 253.36 x 21 = 5320.57MHz CPU-Z Validation"><img src="http://valid.canardpc.com/cache/banner/558936.png" width="352" height="24"></a></p>
<p align="justify">After fooling around with voltages for a few minutes to maximize the BCLK without too much effort, I turned my attentions to Super Pi, both 1M and 32M. I only ran 1M a couple of times and did get 250BCLK to run a couple of times but had freezes opening CPU-Z. This has happened to me before with this motherboard and requires the CPU pot to warm up a bit. I didn’t have patience because I wanted to move on to 32M and didn’t have much time to spend benching. Here are the two best results I have pulled with this combo thus far.</p>
<p align="center"><a href="http://www.techreaction.net/wp-content/uploads/2009/05/1m_5216-1.png" rel="lightbox[488]"><img src="http://www.techreaction.net/wp-content/uploads/2009/05/1m_5216-1.png" alt="EVGA X58 3X SLI Classified" title="EVGA X58 3X SLI Classified" width="250" height="318" /></a> <a href="http://www.techreaction.net/wp-content/uploads/2009/05/32m_5215-1.png" rel="lightbox[488]"><img src="http://www.techreaction.net/wp-content/uploads/2009/05/32m_5215-1.png" alt="EVGA X58 3X SLI Classified" title="EVGA X58 3X SLI Classified" width="250" height="318" /></a></p>
<p align="justify">The first i7 920 under 7 minutes in 32M and if I am not mistaken, under 8 seconds in 1M.  At the time of posting, the 32M is actually 6th globally ranked amongst all CPU&#8217;s on HWBot.org and this 920 absolutely crushes the 965 C0/C1&#8217;s I have tested.  With a little more work on voltages and better memory, there are sure to be quicker times from this combo.</p>

<p align="justify">The EVGA X58 3X SLI Classified has been much heralded in the enthusiast and overclocking forums and for very good reason.  This particular 965 was only able to clock to around 5040MHz on both the EVGA X58 3X SLI and DFI X58-T3eH8 for 32M SPi.  On the Classified, however, I was able to push this processor almost 100MHz more at the same pot temperature of around -75C.  This extra 100MHz mated with a solid set of Corsair Dominator-GT 3&#215;2GB DDR3-1866 7-8-7 memory, got me below the 7 minute mark for the first time.

<p align="justify">Using a fairly typical SPi setup, getting into the 6&#8217;s was a bit of a battle.  At 5GHz it was evident that the setup had the chance to go sub 7 minutes but I had no idea how the CPU was going to clock on the Classified as this was my first session under LN2 working on 32M.</p>
<p align="justify">The only issue I had was getting a screen shot.  After getting sub 7 a couple of times, the system insisted on freezing when trying to open CPU-Z for the screen shot.  Even after an extensive copy wazza process and running 32M, the system didn&#8217;t like CPU-Z&#8230;which obviously wasn&#8217;t making sense.  As it turns out, letting the pot temperature warm up to near -50C was what it took to get the screen shot.  It only took about three Newcastle&#8217;s and a half dozen runs under 7 minutes for me to figure it out.</p>
<p><a href="http://www.techreaction.net/wp-content/uploads/2009/04/6m-59-734_5137_1027_4726-1.png" rel="lightbox[38]"><img src="http://www.techreaction.net/wp-content/uploads/2009/04/6m-59-734_5137_1027_4726-1.png" alt="EVGA X58 3X SLI Classified" title="EVGA X58 3X SLI Classified" width="599" height="464"/></a></p>
<p align="justify">It isn&#8217;t the most efficient run out there and my copy wazza/32M OS needs some work but the goal was sub 7 minutes and that was accomplished.  Thanks to EVGA for another fantastic motherboard and Corsair for a solid kit of memory.  Next up is trying to get that time down by a couple seconds and break into the top 5 overall 32M on HWBot.org with this setup.</p>
