As a benchmarker, the biggest milestone you will come across is your first plunge below -100C. Liquid Nitrogen is -196C by nature, and to utilize this exotic cooling material, you need a fantastic evaporator, or more commonly known as a pot. Much like dry ice, cooling the processor down this cold will decrease impedance that opposes electron flow. This allows for a more efficient circuit, promoting greater stability and overclocking headroom.

After 2 years of research, waiting, gathering hardware, blogging, and toying with dry ice, I have now crossed the line into the “big league” of extreme cooling. Liquid Nitrogen. I was originally inspired after I had the privilege of visiting an extreme overclocking event in Austin, Texas at the AMD Lonestar Campus Headquarters exactly 2 years ago to the day. I got to watch some of the best of the best overclockers such as Kingpin, Chew* and Gomeler work their magic with LN2. I wrote an article about it here.

This event also spawned a video: Xtreme Conditions ( I am in the black v-neck standing next to Chew*)

Without further ado, here comes my first Liquid Nitrogen run: inspired by overclockers, performed by overclockers.

I come equipped bearing:
-one 30L Union Carbide Laboratory Grade Dewar
-one LN2cooling.com Evaporator, one Phenom II X6 1090T BE
-one set of Mushkin Ridgeback 4GB PC3-12800
-one Gigabyte 890FXA-UD5
-one PC Power & Cooling 750 Watt “Silencer”
- two Scythe 120mm Variable CFM Fans
-one Sapphire Radeon HD 5870 1GB
-one container of dielectric grease
-one container of “no-leak” plumbing putty
-lots of neoprene bits
-and a roll of paper towel.

Board preparation and insulation was extremely similar to my DICE run preparation, which is why I have taken no pictures of this particular step this time around. However, I will post pictures from my previous prep. The only difference is I added a small amount of neoprene bits in areas where I ran out of putty.

Grease applied around the socket. The last line of defense against moisture and condensation.

Putty around the socket.

Before I post the results I just want to send out a big thanks to my benching partner Addies, as he helped find the great deal to purchase this dewar, as well as helping pitch for liquid nitrogen, helping me film, and helping me reach some great overclocking results. And I would also like to thank Aaron Schradin of LN2cooling.com for lending me this great evaporator.LN2cooling.com Evaporator

Union Carbide LD-30 30L Laboratory Grade Dewar

I was very proud of how my 890FXA-UD5 held up, as it’s already been through 3 DICE runs (Dry Ice Inception, Second Frost, and Deep Freeze). I had no condensation issues, as I used dielectric grease then layered on plumbers putty and neoprene. The LN2cooling.com pot did extremely well.

Addies and I managed to produce some decent results. Nothing special by any means, but for a first run we’re proud of the results.

Sandra Memory Bandwidth – 22.68GB/s

Thats it for results folks. My next run will include higher valids, Pifast, wPrime, and I will also bench my X4 555 BE which fully unlocks and is a better clocker than my X4 955 and X6 1090T.

I did not expect these results at all, actually I did not expect my IMC to allow speeds this high. Turns out I have a great hardware combination. When I was in the BIOS the speeds just kept going up and up. I eventually tightened the timings down to CAS8…which I thought was amazing for a frequency of 2240MHz.

Post On My Blog

I was just looking at the CPU-Z screen out of curiosity today, when I realized that an overclock on this machine is potentially possible. I was reminiscing on my A64 4200+ X2 HP days, when I managed to overclock the CPU 300MHz over stock using nothing but software (my very first overclock). Eventually I went on the net and grabbed SetFSB and started going through each PLL one by one, until I found on that worked on this particular chipset.

Its sort of lucky that it worked, considering Dell computers are built using proprietary components. The possibility of overclocking these in the first place are because the motherboards are based on retail market chipsets, and utilize some of the same PLL’s as a few boards out there.

I know some of you saw my recent dry ice runs on my Phenom II rig. In a few threads I discussed that for my next run I will have a different pot to play around with — and I assure you that promise was kept.

The video is up! Click here:

|Deep Freeze| – |LN2Cooling.com Evaporator| – |Phenom II X6 1090T @ 5.625GHz|

I got in touch with a friend and he agreed to let me take one of his cooling pots for a spin. Aaron Schradin of LN2Cooling.com has lent me an excellent pot to play around with and review for all of you guys. This pot is usually meant for the purpose of running under LN2 and LHe4. This is seen in the many AMD world record breaking overclocking attempts, which can all be seen over at amdblackops.com. However I will be playing around with the dry ice performance of this pot, which has mostly been overlooked until now.

The new little toy in town is in fact not little at all. This pot is huge. Much larger than the previous aluminum cooling pot I have been benchmarking with. There is also a lot of mass to work with which in turn equals to better cooling. Combine that mass with high quality copper and lots of surface area and you have yourself an excellent cooling pot.

The Pot

I was interested in the packing, a shipping tube made specifically to ensure this evaporator can be safely shipped anywhere.

Here’s a look at whats was included with my package. The hardware, mounting kit, and of course the copper base and aluminum reservoir.

Here is a closeup of the base. A little tarnished, but nothing a little bit of polish can clean up. Usually tarnished copper can be cleaned with ketchup as well.

This pot comes with a drilled in temperature probe hole for to ensure the pot is cooling to maximum capacity.

Here is the base cleaned up. A perfect mirror. It also shows the mounting hardware close up. These springs tightened up will ensure just the right amount of pressure bearing down on the cpu.

The mounting kit comes with the ability to use this pot with all current sockets on Intel and AMD platforms.

The pot threading. It was important not to tighten the reservoir too much when screwing it on to the base or else it will become extremely difficult to remove.

The pot with both parts screwed together is around 16cm tall. That is also about 6.3 inches.

The diameter of this monster is approximately 8.5cm. Once again that is about 3.3 inches.

And finally a shot of the internals taken from LN2cooling.com

The Results

Benchmarks:

CPU-Z
SuperPi 1m
SuperPi 32m
wPrime 32m
wPrime 1024m
PiFast
3DMark 06

For the results, I will be comparing the scores on this pot to the scores from my last run on my Duniek Aluminum pot.

CPU-Z  -  Core #1 5.579GHz @ 1.744Vcore – Validation

For this CPU-Z valid I went all out overclocking my chip’s strongest core, core #1. As you can see I disabled all but 2 cores, and ran down a bunch of other settings to get this. Before settling on 5.579GHz, I was able to hit 5.624GHz but was not able to validate without crashing. Maybe I will make this on my next run. My previous run on the aluminum pot only netted me a max validation of 5.547GHz.

CPU-Z  -  All 6 Cores, 5.500GHz @ 1.696Vcore w/ 3000NB and 1000MHz 7-9-6-15 memory

During my last run, I was only able to push 5.4GHz all 6 cores. This goes to display how the increased mass and the copper material of this pot makes for more efficient cooling and coping with the load of all 6 cores pushed to 5.5GHz.

SuperPi 1m  -  12.625 seconds

My old time on the aluminum pot was 12.797. SuperPi 1m is highly inefficient on Gigabyte boards for whatever reason, but I still managed to surpass my old score and net the top 1m DICE score for this processor on hwbot.org.

SuperPi 32m  -  12 minutes 58.219 seconds

Due to the fact that this pot can hold down better temps under load, I was able to increase cpu speed in contrast to my previous run. I broke the 13 minute barrier for 32m on DICE with this processor.

wPrime 32m  -  4.765 seconds

Not much to say here. I’m thinking I could have fine tuned my setup for a higher score, but I settled at this time. For my next run I will get a faster time.

wPrime 1024m  -  151.25 seconds

I was astonished at the pots ability to handle the load of all 6 cores stressed. All extreme benchers know that 1024 takes a bit of work to pass at higher frequencies. I managed to pass at 5.125GHz. The previous pot would not budge at over 5GHz.

PiFast  -  20.50 seconds

Once again, another untuned run. However I surpassed all of my personal bests with this one.

3DMark 06  -  28306 3DMarks

For the first time in a long time, I decided to test out some 3d stuff again. I did this mainly to gauge how the evaporator handles 3d load. This is where I saw my biggest improvement from my old pot. During one of my 955 X4 BE runs, I found myself only able to run 06 at 4.520Ghz using the aluminum pot. I was able to push out and run 5.25GHz stable under the load of 3dmark06.

That is all for the results. However, here are the improvements I made with the new pot summarized into one chart:

Conclusion

This is an excellent pot for all types of extreme cooling. Remember that this pot is not primarily for DICE. It begins to shine once under LN2 and LHe. The 99% pure copper design, combined with the excellent internal surface area and the mass of the base makes for extremely efficient cooling. The install is pretty straightforward as well.

This pot helped me break all my personal best’s that I made on my previous aluminum pot. Half of these runs still have headroom to tune as this pot is very efficient. In the BIOS it read -75C at almost all times, which is only 4C above the actual temp of dry ice itself. This is next to impeccable cooling performance. Any extreme bencher would love this evaporator.

I would like to thank Aaron Schradin over at LN2cooling.com for lending me this pot to play with.

Also, I should have another overclocking video of this run posted up on my youtube channel soon.

Over the recent months I have watched and observed as the Phenom II CPU found its niche within various enthusiast communities and online forums. Users have been provided with an excellent, all around, 45nm AMD quadcore.

However, there is one factor that people still find confusing and unclear. Overclocking the Phenom II. Why are people so confused?  One reason may be because they add a lot of new variables and overclock differently than the competitors chip. Some may choose to see Phenom II overclocking as a headache, or a fresh challenge in their hands. I choose to see it as a fun challenge.

Now, one area that people have mass amounts of problems is Ram/Memory stability and overclocking, as well as what role the IMC (NB) plays in affecting ram and performance.

The IMC

The IMC links the CPU to the memory in a system. In the case of the Phenom II AM3 series, DDR2 or DDR3 memory is supported. One important performance factor that people neglect when applying daily overclocks to their Phenom II systems is that the faster the IMC speed is, the better your memory will perform. Additionally, you have to take into account that overclocking the IMC may require voltage increases on the CPU/NB. This may add unwanted heat which happens to be the Phenom II’s arch-enemy. While overclocking though, always keep in mind that the IMC is a very touchy factor in an overclock. If it’s not working out for you, you perhaps need to try different combinations/ratios. When stress-testing the IMC, the most preferable method is Prime 95 blend test for at least 2-3 hours.

The Ram

The memory within an AM2+ or AM3 configuration acts and requires different tuning than your average Intel setup. The RAM ties strongly in with the IMC. If the ram is unstable it can cause instabilities in the IMC and vice versa. Ram on this platform tends to like lower memory frequencies and timings. When tuning ram, take into account every setting you can find in your BIOS. I mean it. Experiment. It may seem like a lot to take in, but hey, grab a coffee, a pad of paper, and sit down for 2 hours and do some testing. The second important portion of RAM clocking is that you must know what type of IC’s your RAM uses. This already will put you in a great position to fine tune the ram. Plenty of online resources can help you identify your IC’s if you do not already know. Once again, after clocking your ram, 100% stability can be found using Prime 95 linked above. Stability testing for benchmarking overclocks can be done in SuperPi 32M.

The CPU Cores

Since the focus of this article is geared towards Ram and IMC clocking, I will be quick on my CPU Cores description.

Phenom II CPUs are usually very intolerant to high voltages when using air setups. Be aware that more voltage may decrease stability going past 1.5V on quad core versions of Phenom II. Also remember that these cores love cold temperatures and scale brilliantly with it. This can be seen in my Canadian Winter blog series, as I will soon start to compare the scaling from normal air temperatures to very cold air temperatures. Even without winter air, every degree that you can lower your temperatures in an air setup is worth it towards overclocking.

Pulling It Together

This creates a 3 component chain wherein lies the secret to stability and performance. You have to realize that if any component in this chain (CPU, NB, Ram) happens to be unstable, the chain will not be complete and you will never see stability. In order to maintain stability, you have to find a sweet spot for each variable according to your setup. There are a plethora of ways you can approach this. However, I discovered that some specific methods are more efficient than others.

The Overclocking – Guide

Starting With The RAM

It is unarguable that even out of the box, with bare bone stock settings in a BIOS, memory will cause the most headaches for the AM3 setup. For example, prior to Phenom II X6 chips which include a brand new IMC revision, you could not take a standard 1800MHz 9-9-9-24 set of DDR3 and get it to run at it’s rated speeds without doing some tweaking to settings in the BIOS . Even sticks that can in fact run at rated speeds out of the box on an AM3 platform can be a pita for stability. This is in contrast to the CPU and IMC where on stock settings, they are supposed to operate flawlessly without any rifts.

1) To begin your overclock start with a default ram clock and timings. For example: 1333MHz 6-8-6-24. This can also depend on the stock specs of your ram to begin with. That is always a good starting point (excluding stock 1800MHz and 2000MHz sticks, as it is unlikely you will get them to run properly at first starting at such a high frequency).

2) You can start speeding up your ram in a variety of ways. By increasing clock speed (Through dividers and HT Ref Clock), tightening timings (adjusting latency timings, and sub-timings in the BIOS), or combining both for the ultimate overclock. Start in small increments on the frequency and timings. Remember that the 4 major ram timings (CAS, tRCD,tRP, tRAS) are very dependent on what IC’s your ram has, and changing these more then one value at a time can cause instant instabilities requiring a CMOS reset. Also remember that it is contradictory to loosen all timings significantly to increase frequency and vice versa. What increase in speed will there be if you are just trading off one thing for the other? However fiddling around with some sub-timings and loosening can help stabilize higher frequency overclocks, while minimally affecting performance. Generally, the most important part of ram clocking is getting familiar with your ram, and what settings greatly affect performance and stability. This is a lengthy process and there is a lot of rebooting involved. General ranges to shoot for would be: 1333MHz (CL 5 or 6), 1600MHz (CL 6 or 7), 1800MHz (CL 6-8), and 2000MHz (CL 7+). What range you want to fall into also depends on your ram, the quality of the IC’s and your ability to tune the timings. Remember to always experiment as much as you can and play around with everything available!

Here are a few sources that list different DDR3 IC’s:

http://ramlist.i4memory.com/

http://www.hardwareluxx.de/community/f13/hardwareluxx-ram-datenbank-ddr3-404293.html#post7147707

3) With each small change you make it is important to know if you are stable or not. In windows you can use Super Pi 32m as a preliminary stability test. This will not gauge 100% stability, but it will help you figure out what range you will be able to overclock within. Passing 32m also means that you are stable for most benchmarks. If you cannot pass 32m, then your ram is not remotely stable, and you can then adjust your settings accordingly. For full stability testing for 24/7 overclocks, utilize Prime 95 for at least 3 hours. During any stability test, it is important to eliminate the risk of cpu cores and IMC (NB Frequency) causing any stability problems. This is to ensure that if there are instabilities, they are occurring within your ram, not within your processor cores or memory controller. So make sure that the NB and CPU are as close as possible to stock settings prior to testing.

4) If you do find instabilities in your overclock there are a few things you can do to help stabilize them. First things first. Do not go crazy with the ram voltage. In moderation though, it can help. Recent DDR3 modules cannot take too much voltage on standard cooling. It is common for a lot of ram to come stock at 1.65v. Usually this ram should not exceed 1.75v for risk of degradation or damage to the ram. However some IC’s are known to like voltage more then others. Micron D9’s come stock at 1.8v usually and love voltage. Now that that’s out of the way, here are a few tips for stabilization. Increasing the CPU-NB voltage slightly is always helpful, regardless of whether the NB Frequency is at stock. NB Voltage is a setting in the BIOS that refers to the physical northbridge on the motherboard. Do not confuse this with the IMC. In some cases, increasing this voltage in moderation can help stabilize high ram overclocks. Another tip is to ensure that both of your ram sticks are in slots 3&4. On some Gigabyte 890FX boards these slots offer higher headroom for ram speeds. Keep the ram cool, pointing an extra fan toward it can always help. The final tip is to adjust drive strengths, which I will talk about in depth in the next step..

5) In the BIOS, there is an advanced set of ram settings. These are called drive strengths. Essentially you can use these to stabilize the ram further. It is very hard to understand which changes in drive strength values are useful unless you utilize memtest. You need to boot from this program off a CD or USB before going into windows. When changing the value of a drive strength always remember to do it for both sticks of ram (sometimes labeled DCT0&DCT1, or A&B). Only changing one value at a time, run a round of tests in memtest. You want to change drive strengths until memtest gives you as little errors as possible on the test suite. Once done so, you have essentially helped stabilize the ram or have created more headroom for overclocking. Remember that you cannot do this if you are getting preliminary tests of hundreds or thousands of errors in memtest. You need to begin with a handful of errors, and this is what you must use as your baseline value that you will start tuning from.

Adding In The Northbridge Overclock (IMC)

Once you have a proven ram overclock that is stable, it is time to work on the IMC. The IMC can vastly increase performance of the memory subsystem in all aspects. It allows a memory overclock to work to its full potential. Overclocking the memory controller is very similar to overclocking the CPU cores. It is much easier to overclock and understand then ram overclocking, as there are less variables in play.

1) When overclocking the IMC you need to know what will affect it’s  headroom. On the Phenom II X4, X3 and X2 chips, the NB Frequency has a max stable range of 2600-3000MHz depending on your chip. For 24/7 overclocks this frequency usually falls around 2700MHz. This will require voltage increases in the CPU-NB option in the BIOS.  However, Phenom II X6 chips are slightly different. Their max 24/7 range is around 2800MHz-3000MHz. They also require less voltage then previous chips.

2) Start by increasing the NB multiplier till you hit around 2300MHz-2500MHz. Try stability testing this in Prime 95 combined with your ram overclock. Do not adjust the voltage to the IMC just yet. If this passes, then move up a notch. Go until the IMC causes Prime 95 to crash, and then start increasing voltage in moderate increments on the CPU-NB option. When overclocking take into account that the HT Ref Clock (which also controls your ram and cpu frequency) will become the base that is multiplied by the NB multiplier to get your NB frequency. This means that each multi increase will have a bigger increment as opposed to if the HT Ref Clock was left at 200.

3) For CPU-NB voltages, do not exceed 1.5v. After that the IMC won’t really scale well. Also note that each time you add voltage to the CPU-NB, you are adding to the overall heat output of the chip. So this is something to watch under air cooling, as it could hinder your CPU core overclock that you will later add in. The rule of keeping the chip cool also applies to the NB. A cooler chip could equal a higher overclock headroom.

4) When stability testing your final NB overclock, run Prime 95 for at least 3 hours on the blend setting. This is to ensure that the ram and NB are both stressed to the maximum during the 512K FFT iterations. You may wish to run this longer then 3 hours if you like, but that is more stress then any real-world application can offer. After this is stable, then you have yourself a final overclock of the IMC and Ram.

The Final Step

For the final step, you would add in your CPU core overclock. A great guide to check out for overclocking the CPU is my previous guide here. All this information should help in completing your final stable, 24/7 overclock. Here’s an example (it was only 2 hours because of time constraints):

I hope you guys enjoyed my second guide, stay tuned for more in the future.

Oh and there is an all 6 core max OC result in the video that I didn’t SS.

Video will be up soon.

Thought you guys would appreciate some pics

Went to the store today and bought the following:

Dielectric grease to coat the board to prevent condensation from getting at the electronics of this very precious motherboard.

I couldn’t get any moldable eraser, so I though this would do. It said on the package that it was non-drying, non-cracking, and prevented seepage from water. It provides just the perfect seal to prevent condensation.

Dielectric grease applied around the socket and board.

Plumbing putty applied around the socket. Nice and easy.

Picked up my box of goodies from the benchpartner (Addies) today.

The DICE Pot

Ready To Go

Stay tuned guys. After my DICE run tomorrow, I will be posting a massive result thread, and making an HD video of the run.

Hey guys. I did some more tuning, got more results. So I am throwing together my second slushbox blog. To see the first one, click here.

I tried to place my rad in the cooler this time so that the ice covered more surface area. This resulted in idle temps of 0-1C. So i pushed my Phenom II X6 1090T even further.  Here goes my second set of results.

4.806GHz All 6 Cores @ 1.648Vcore 1C idle – Validation

It took me an hour to get this validation. I could only previously validate 4.73GHz. I needed to reposition my rad for better surface area of ice. Then I had to wait for my temperature to drop to 0-1C before I made the final push. I couldn’t get any further without going above 1.648Vcore. Here we have it, 4.806GHz on the slushbox. Can’t wait to see what this can do with DICE.

4.902GHz Core #1 @1.648Vcore 1C idle

I chose 3 of my chips cores for this result, meaning I had to disable 3 in the bios. I had previously tested all 6 individually, and the best clockers were cores #0,#1, and #4. The best of the three was core #1, the one which I decided to push for this screeny.

SuperPi 1M – 4.7GHz @ 1.616Vcore – 14.555 seconds

This is a very fast result. The upper limit for my cpu in 1m. Again, this result only uses three cores. I believe I could improve on this score by tuning my ram a bit more.

SuperPi 32m – 4.608GHz @ 1.616Vcore – 14 minutes, 53.148 seconds

This is the first time I have ever broken 15 minutes in 32m without using dry ice. This score could also be improved through a little ram tuning.

UPDATE: Low Volt Overclocking

I wanted to see how far this thing would go without using insanely high volts. It’s pretty amazing what a little bit of cold can do.

This was my boot speed. 4GHz using only 1.296Vcore. That is stock for these thuban chips.

4.5GHz only requiring 1.44Vcore. These things LOVE cold!

As always, these 1090T’s follow suit with their x4 brethren and respond well to cold. I can’t wait to throw some DICE on these and see how they scale. I’m looking for 5200MHz+.

Thanks for checking out my second session guys. I hope this was interesting. And I also hope to inspire many others to put their Phenom II’s under cold. You will not be disappointed with the results.
