help me oc sli'd 460's

post #1 of 5
Thread Starter 
hey guys. i got two msi gtx 460's in sli. ive overclocked 1 of the cards before i bought the second one. this being my first sli setup, i have no experience at overclocking 2 gpus in sli.

whats the best way to do this? one at a time? i got msi afterburner and kombuster. the two gpus have two different vid's so im assuming they will need different voltages to maintain stable overclocks. should i pull 1 card out of the rig and overclock till i find the sweet spot then do the same for the other?

any help is greatly appreciated. thanx guys.

Isnt there a little check box that says 'apply to both cards' or something?

yeah there is, but if 1 goes unstable how would you know which one it is? also if i apply to both cards it will apply the same voltage as well. this seems very complicated.

Then back down the OC. Unless like you said, you wanna find out what each card can do by themselves. One by one.

would it matter which one it is? If one of them isn't stable, then it wouldn't work anyway.
