I had my first run with my Tek-9 tonight as well as my first GPU on LN2. Well....first successful/semi-successful run hehehe.
Here is the system.
P5K Vanilla voltmodded (Vcore/Vmch/Vpll, and all 3 measure points)
Q6600 G0 cooled on LN2 by a Dragon Evo 2.4 pot
8800 GTX (stock volts) cooled on LN2 by a Tek-9
Corsair HX620W
WD Caviar IDE 160gb
2 X 1GB Mushkin Extreme Performance 1066mhz
The max core clock I could achieve stable enough for 3D06 was 729 (real).
The max shader clock I could achieve stable enough for 3D06 was 1750 (1728 real I believe?)
The max memory clocks I could achieve stable 3D06 was...stock. 950
I ran the GPU pot anywhere from -30C to -50C. Should I be running colder?
A few others questions.
1. Regarding the memory clocks. Is this because there is a decreased heat dissapation from no timm/heatsinks/fans on them anymore? As far as I have been told its not a lack of voltage. My 8800 GTX has Hynix chips as opposed to the Samsungs, and from what I have been told (personal communication - ViperJohn from OCF GPU forums) the Hynix memory chips do not need any extra voltage to overclock and in fact, more voltage to these chips actually hinders overclocking potential. Agree or disagree with that statement? How can I get to increase my memory clock settings?
2. I was hoping for more on the core clocks than 729 even stock. Is that decent for stock volts LN2? I was hoping for closer to 800ish.
3. I was unable to run 3D05 at the above mentioned settings on 2 attempts (CPU 490X9, GPU 729/1750/950) but was able to run 3D06 repeatedly at those settings. on 3D05 1x it restarted and 1x it hung. I dont recall which test it hung on 3D05 though. More likely CPU or GPU related for 3D05?
4. Did not get to run 3D01 as I ran out of LN2 3D03 I got 1 attempt at, and it hung near the end. Cant recall the test either and settings were same as above.
5. Canyon Test 3D06 I was getting red and green "sheet-like" artifacts every single time I ran that test. Everything else looked 100% artifact free and crisp/clear. Is there something particular about that test that causes this? I have not seen that before. At first I thought it was because the GPU pot was not cold enough, but that was not it.
Even considering that I was not able to OC the memory, Im disapointed in the scores. With the same CPU at 3.9Ghz and 8800 GTX on air at 660/1620/1050 I was able to get 15,800, and only 16,800ish on LN2 for both GPU/CPU. I definitely need to look into some additional tweaks and suggestions are always appreciated
Thanks for looking!
