OCing my gtx460 SLI noob

post #1 of 5
Thread Starter 
So I have my 2 gtx460 hawks installed and I want to OC them, I used afterburner to oc the core up a little on stock voltage and I looked at hwmonitor and it shows 2 different voltages for the GPUs and when I run OCCT the testing for the GPU is greyed out and I can't run the OCCT for the GPU. How long should I test with furmark or kombuster before I can tell it's stable? should I use any other programs? Thanks

Huh. I don't know about voltages, but by default the primary card should make all the clocks of all the other cards the same as it's own. Perhaps you need to tweak voltages for each card individually?

There should be an option that when you make a change to one GPU, it does the same to the second GPU... enable that.

Also, OCing a GPU isn't too hard, it just requires time and patience. I always do memory first. Up the memory and keep running 15 minute Furmark tests until you've found the point in which your can take the memory no further. Once you've found that point, double check it by running a test for a few hours to ensure maximum memory stability.

Core is a little different. For core I find it best to do the same thing, but then play video games for a few hours.

i can't seem to figure out where to find my GPU voltages, I see in afterburner to increase my core voltage but i can't see what the value is actually at. right now im OC'ing core first I guess. what is the max safe voltage for the memory to be oc'd at?

should I just put the voltage to +100mV and then increase the core?
