Max oc on msi twin frozr 660

post #1 of 4
Thread Starter 
I was overclocking my card, it has no factory oc. I was wondering what a safe oc is on that. I have increased the core clock my 100mhz, and the ram by 147mhz, and my temps are barely getting to 54c. anything i should worry about?

i also cant figure out how to increase the shader clock

Each card is different. Some overclock better than others, and some worse. We have no way to tell you what the max safe OC on your particular card is. Best thing to do is increase the clocks bit by bit and re-test for stability in games.

I like to use OCCT, Crysis, and Battlefield 3 to test GPU stability.

Im not an experienced OCer, but I would say that you can raise the clocks pretty much as high as you want to without harming your card, as long as you don't touch the voltage (not sure what software you're using, but if you have enhanced the frequency range obviously don't max it, use common sense and don't make too big leaps).
When it comes to voltage I think it is rare to harm the card if you only raise the voltage with a single digit percentage of the stock voltage. What is the stock voltage for your card? (depends not only on the model/brand, but also on how it's binned).
