After switching to Akasa silver based thermal paste, the temperature was much more stable. So it was time to do SLI runs!
The setup is as follows:
Intel QX6850 at 11 x 462FSB > 5082MHz cooled by LN2
EVGA 680i SLI Motherboard
2 x ASUS EN8800 Ultras @ 918/1224MHz cooled by Dry Ice
GSkill 2 x 1GB HZ DDR2 Memory
Silverstone Olympia 1000w Power Supply
Nice Afternoon’s worth of benchmarking. Will probably try some LN2 on GPUs to further the score.
