update time...and the results are quite nice, up to 585FSB benchable under LN2 and another board hits 15K read bandwidth in Everest. until Nehalem drops, that is still quite the feat :biggrin:
I finally got a hold of a pair of GTX 260s, EVGA Superclocked + GTX 260s to boot. These two are from a retail store and appear to clock about as good as others with stock cooling in normal ambients. I only have them for a short period of time but will do my best to make use of the them as best I can. First up will be some clocking with the cards on air and the CPU under LN2 to get a feel for what they can do on this board and how the CPU will clock FSB under cold on this guy. Here is a complete list of hardware used for these results and then a photo of the setup as always:
The setup as tested...
- CPU: Intel C2D E8600 (L814A526)
- CPU Cooling: Rev3 CU Mousepot w/LN2
- RAM: Crucial Ballistix 2x1GB PC3-16000 CL9 // G.Skill HZ 2x1GB PC3-12800 CL7
- NB Cooling: Swiftech MCW30 / MCP655 / MCRES-Micro / PA120.2
- SB Cooling: Thermalright HR-05-SLI
- PWM Cooling: Swiftech MC14 x 4
- GPU: 2 x EVGA GTX 260 Superclocked+ (177.92)
- PSU: Ultra XPro 750W
- HD: Seagate SATAII 80GB 8MB NCQ
- OS: Windows XP Pro SP3 (fully updated)

I missed any Vantage or 06 benchmarks because I bugged the CPU and then it was all downhill from there. I didn't want to stick to the same clocks for each benchmark as 05/06 are limited by FSB so I basically maxed out each benchmark. The goal was to test FSB clocks for each benchmark as this was the first time running LN2 on this board. Consider these the shakedown runs, with most tweaks applied...be sure to note the bandwidth in a few of them, 15K on yet another 790i board for this guy :thumb:

Things went well and getting down to temperature went quite smooth. I was able to boot at the clocks you see above no problem and the board responded as it should throughout the session, until I bugged the CPU and warmed it up with a blow dryer. That was the end of that as the pot was just too unstable to run anymore. Temp swings were nightmarishly quick and all over the place. The pot needed to be warmed up to -80C before the bug went away, with the RE, this CPU would bug and 20 seconds later it was back in action without any outside heat applied which made benching a breeze. With this board, I will just have to make sure not to cold bug the bloody thing.
The other thing I want to mention is that my Ballistix will absolutely not boot at higher than 1050MHz. I thought it was a board issue and threw the G.Skills in to find they were booting just fine at 1096MHz so clearly not a board issue and related just to the Ballistix.
I might have one more session with the cards on air and CPU on LN2 before three potting it, but after getting these scores, there is no doubt I will be getting the GTX 260s cold at some point, even if I am only benching the CPU at 5850MHz. Might even bother with some 32M action at 5850MHz/1096MHz 8-7-6, should be some blinding fast times for the clocks.
