e8600, 2x 4870x2's, Rampage Extreme, CSX Diablo

For my first LN2 session I assembled one beast of a test bench. My aims were 6Ghz 3d stable, which I didnt get working until 2:30AM and I passed out at 3AM so not much testing. I also wanted to push my 8600 because I have seen a few of the same batch doing 6.2-6.3 3D stable, and 6400-6500 1M's. With no coldbug even at -140 I think I may have a winner on my hands here. The REX was a pleasure to work with. Great ram clocking, awesome stability at super high FSB and clocks, and one hell of an extensive BIOS! Great job Asus.

The CPU pot I had is OK at best for LN2 benching, its much better for DI. Temps swing wildly under load, and when pouring. The best I can do is keep it within a 10 range fluctuation. I had it @ -110 to -120 for most of the session. *Sees an F1EE in his future*

Hardware Setup:
e8600 820Axxx -140C lowest tested no CB yet
Duniek Copper/Aluminum stepped pot w/ Fluke 52S thermometer
2x 4870x2 w/ Asus TOP Bios stock heatsinks/no mods. (max 850/960)
2x Dryer tube pumping 2C air into the GFX Cards w/ 2x Delta fans (a 140CFM and a 240CFM)
2x1 GB CSX Diablo (good up to 1080Mhz 8-7-6-18-1T@2.1v or 980Mhz 7-6-6-15-1T@2.1v)
Asus Rampage Extreme (Booted at down to -115C, not CBB yet either)
Duniek Northbridge Copper/Aluminum Pot mounted onto existing heatsink assembly (removed waterblock). Not going too cold here because of condensation issues
Xion 800 Watt
Xitech POST Code PCI Card
Vista 32 Home vLited

Bios Setup:
600FSB (no setfsb)
1.9 vCore
1.45 vTT
2.1 vDIMM
1.65 vNB
loadline disabled (keep rebooting during windows splash screen if enabled)
Ram set 7-6-5-15-1T all else on Auto. 333Mhz 5:8 strap, memset the subtimings.

Dual Card Results

2001 sucks in Vista, but I still managed to take 4th place for this setup.

03 is of course a 4870x2's wet dream. Too bad I didnt encounter the "normal" performance for these cards, but instead had the low score "bug." Rubbish imo since only 5-10% of cards get the "normal" performance and the rest have a low score "bug."

05 I was very happy with, although I just couldnt get 41k - so close!

06 was a surprise as I was expecting may 28-29k, but actually broke 30k.

AM3 is another bench that crossfireX in vista didnt fare to well in.

A quick run I started the session with. I forgot to re-run at higher clocks

PiFast was the only 2D bench I ran. I was curious how performance was in vista, and surprising to me it wasnt bad at all. XP is still a touch faster but... this run was TOTALLY unoptimized. Just booted & ran it.

Single Card Results!

3DM01 - Not tweaked or optimized at all. Will be focusing more on 01 with my 4870 and 2x4870 as I believe they are better suited for it.

3DM05
2008-12-07 16.46.51.jpg

AM3 - last bench I ran when I finally figured out how to get over 6100Mhz Not sure how much more headroom I have until I hit the next wall though, since I didnt push it very hard.
2008-12-07 17.27.26.jpg

3DM06
2008-12-07 17.38.58.jpg

3DM03 I was getting ultra low score bug When I first ran the card in 03 (on air) I got about 96K (at 4.8ghz) now at 6Ghz I was getting mid 80K.... no combination of reboots/psu power down/etc would get my scores normal Even though I didnt hit my 6.2ghz goal, I was happy with the session. I am sure with more tweaking I can get higher. My pouring skills are also getting better and I can control the temps within a tighter range. I definitely need a new pot though.

As for skill... im still working on it. Ive been lucky to be running a Pc parts business... I can go through some gear b4 I find the good ones then sell the rest. Lucky also with my CPU picking this one is a gem, I just have to get a F1EE on her and take her to -160!!

Sure batch #820A405 (gomeler has same batch 6.2 3D, 6.4 1M, CB -118), I will be running 2D benches on LN2 Friday if I have time.

Here are some single 4870x2 3D air cooling results. Using TRUE with a 240CFM Delta pulling cold air from outside.
