Then I decided to go higher since overclocking is all about finding out the max stable speed. So I took just the clock up to 761 and played. It crashed. I restarted PC, added 1 bump of SB Voltage (up to 1.23v) and ran Crysis:Warhead, I-could-not-believe how fast Crysis:Warhead was playing there for a second, but it crashed again.
A pair of 285s can slay crysis. I haven't needed to bump up the SB voltage unless at extreme cpu clocks, adds a bit of stability then. Never really experimented with it at lower clocks, have to look at that. Have you tried different drivers & see if the nvlddmkm error is still there?
Crysis benched with volt modded 285s (hardmodded, no software voltage control for 285s)
