The Package

The memory comes in a plastic package. All needful information you find on the paper enclosed inside the plastic and on the memory modules.The modules have nice looking green heatspreaders filled up with green LEDs. The LEDs located on the bottom of the modules are lightning every time, but the LEDs located on the top side of the modules illustrating the memory usage.If the memory module is idle the LEDs blinking very slow, but while memory stressing the LEDs blinking very fast.

BLINKING in IDLE

BLINKING in LOAD

Test rig and methodology:

MSI P55-GD80
3×1GB Crucial Ballistix Tracer PC3-10600(picked two from them for dual channel)
Intel Core i5 750
Gainward Rampage700
Akasa eXtreme Power 1200W 80+

I tested the memory with the default voltage registered from the manufacturer 1,65V. And with different memory timings (CL6-6-6-18, CL7-7-7-22, CL8-8-8-22, CL9-9-9-22) I tested the max reachable stable frequency. For the stability check I used the utility Linx with problem size 13000 and 5 loops. To the stable frequencies I added the Everest cache and memory benchmark to see the difference between frequencies and memory timings. So enough word here are the results.

Results

622.5MHz Cas 6

718.2MHz Cas 7

813MHz Cas 8

828MHz Cas 9

Conclusion

The memory is very great for every day use and have a little overclocking potential. The blinking LEDs can interfere with some users , maybe good for modded PC cases.

Parts used in the test:

MSI P55-GD80 BIOS v1.7

2×2GiB Kingston HyperX 1600 CL8

Intel Core i5 661

Sapphire X1600Pro for CPU tests, MSI N260GTX Lightning for 3D Mark 03 test

Akasa 1200W 80+

Started to test the max BCLK.
After some restarts and VTT voltage rising to 1,392V I managed to get into Windows on 250MHz BCLK with 2 cores and HT enabled. Then I used the buttons for BCLK rising on the board and I got the max. validated BCLK of 253MHz.

After I found the BCLK limit I started to clock the CPU for max. frequency validation. First try I stopped at 5300MHz 1.64V. Damn!!! More no go. After a hour of freezing, rising voltages, lovering voltages a idea lighted up…what if the problem is the memory divider? And I was right! It has problem with 4x memory divider to run the memory more then 1750MHz…With divider 3x no problem. So a little afraid off the divider problem I went back to the max. frequency…and after some button pushes on the mobo I get a frequency of 5761MHz 1.64V, VTT 1.366V, PLL 1,55V.

Then I played a little with SPI 1M, SPI 32M and PiFast. Here are the results:

SPI 1M: 7.656s – CPU: 5536MHz, MEM: 664MHz CAS6-7-6-21 1T

SPI 32M: 7m 39s 062ms – CPU: 5511MHz, MEM: 661MHz CAS5-7-6-21 1T

Hexus PiFast: 16.86s – CPU:5561MHz, MEM: 667MHz CAS5-7-6-21 1T

And at the end I run 3D Mark 2003 with MSI N260GTX Lightning clocked at 792/1584/1050MHz(Core/Shader/Memory) with the result:

68981 points – CPU: 5461MHz, MEM: 655MHz CAS6-7-6-21 1T

Thats all for now from single stage cooling… with the teammate we plan to run it on LN2 in a short time… so stay tunned

I had a little time last week and I done some pretesting with the HIS HD4890 1GB that it can do on cold air form outside – next time maybe extreme cooling power were used.

The components I used for the testing:

E8600 Q822A435 @ 4.5GHz 1,35-1,4V on h2o

Asus P5Q-E BIOS 2101

2×1GiB Patriot eXtreme performance PC8500 @ 500MHz CL5-5-5-15 2T 2,1V

HIS ATI Radeon HD 4890 1GB DDR5 on 100% FAN stock cooling

Maxtor 6V080E0 80GB SATA II

Akasa 1200W 80+

WaterCooling part used in the loop:

Laing DDC-1RT

D-Tek Fuzion v.1 w/o noozle kit

Black Ice GT 360 Stealth Lite + 3×12CM FAN @ 12V

10/8mm PUR tubing

2l expansion ghetto bottle

Setup photos

As usual I started on default voltage and it says 950MHz on the core and 1150MHz on memory. But I wanted more.

So I used the GPUTool and increased the core voltage on the max what it can be increased by software 1,45V and started to testing.

For 3D Mark 2003 the clocks stopped at 1030MHz for the core and 1150 for the memory with the result 76 841 points.

3D Mark 2005 I only could run at 1000MHz core and 1150 memory clock speed.    The result 29 686 points.

Same as 2005 I could run 3D Mark 06 only on 1000MHz core and 1150 memory clock speed. With the result of 20009 points.

And now the surprise. 3D Mark Vantage I could run at 1040MHz core a 1175 MHZ clock speed.  With the result of  11525 points. (12786 GPU score)

Even run Aquamark 3 but not surprised with the result. Only 248 912 points. Maybe a driver or operating system issue or something else.

Not bad results, but with a better CPU power the results will be a little better. So now I´m waiting for my new Core i7 setup.
