Overclocking Gpus while in SLI?

post #1 of 5
Thread Starter 
Do I need to overclock each card separately? Can I do them at the same time? Will it affect my Overclock on my cpu? When I added the second card I had to tweak some voltages again

please help thanks

It shouldn't affect your CPU overclock, unless the second card draws too much power for your PSU to handle. You probably had to tweak voltages because your NB had a second card to deal with, hence more stress.

Overclocks can be affected by the additional heat generated by having a second graphics card.

Yes. Though you will only see one slider bar for the core and one slider bar for the memory, any alterations you make to the clock speeds of core and memory will be applied to both cards simultaneously.

Looked up your psu... 49A on 12v Rails is plenty...

I use riva tuner, set up nvidia control panel for "SLI Mode" and "Force Split Frame Rendering"
Then OC, it will be applied to both cards as you will se temp rise on each one when stressing them..
RivaTuner to OC.
ATI Tool to scan for artifacts..
