took out the 163 and put the card 430 in it. ran oc scanner stable 1.15 800/1600/1950.
but when i put both cards in -- i get that random shutdown/restart whenever i bench and program shutdown when i play metro. so it's not a PSU issue that my V1 TPQ 850 isn't drawing power correctly?
I'd try dropping the video memory back to stock clocks and seeing if it fixes the issue. And then OC it slowly back up from there. I've found that memory on Fermi's is less stable in SLI than it is w/one card. Core too, but mainly memory.
Honestly, just OC'ing the two cards while they are in SLI makes more sense than doing them individually.
Also, I'd drop your CPU overclock off, just to test and see if that's the issue. Bumping up your IOH (chipset) voltage a notch (from like 1.1V to 1.2V for example) is also worth a try.
By NO MEANS does that fact that both cards do some particular clock by themselves, but not in SLI, dictate that the 'issue' is your PSU. It COULD be the issue, but def. doesn't have to be.Edited by brettjv - 8/30/10 at 6:16pm
