975 at 1.200 VS 1000 at 1.245?

post #1 of 8
Thread Starter 
Hi guys,
Just finished overclocking my 6790 "again".

Now after testing many core clocks at different voltage and all i am confused.I can have stable 975 Mhz at stock 1.19 v(Altho i set vcore to 1.2 to just avoid any stability problems.Its fine even with 1.19 for 1 hour of furmak and 3+ hours of crysis 2 @ ultra dx11).But to hit 1000 i have to set the vcore to 1.242,and again i set vcore to 1.245 to avoid any stability problems.

So what clock should i use?

I am even think of 1008 MHz (20% OC ) at some 1.255v (or more?)

If you are worried about the longevity of your card, 975.

Personally, unless you are on waterblocks, I would keep stock, and ramp the OC only when you game.

What are you gaining with these high clocks? 3 frames per second?

its not worth using the extra juice for the small gain in performance giving the amount of stress and possible damage that may occur for what your gain will be stick to the linear clock
