I got them installed with a fresh OS.
Not too impressed.... Using either afterburner or precision x, I have not been able to clock them higher than +100 core +550 mem @ +132% w/ volts @ stock or 1.175v.....
This leaves me with a 3dmark 11 score lower than the 7970's (which is in my sig). Here-> http://3dmark.com/3dm11/3185121 CPU was at 5.0ghz even though it shows 4.2ghz.
Anything higher than +100 core gets me a driver kernel stopped responding error. Anyone know of a work around or tweak that I am unaware of? Disable power states, voltage mod or driver tweak?
Maybe if I switched the cards around I could get a higher clock having the other one as primary? Temps under load dont push 60'c with custom fan profile.
Need some help, at this rate these 680's are going back.
Here is what I have noticed with my GTX 680. Clocking the core makes much more of a difference than clocking the memory and having a high memory clock creates an issue where the core does not clock as well.
For example I know that I can add +600 to my memory but if I do this then I can only add +140 to my core. If I leave my memory at stock then I can add +190 to my core. This results in better performance than messing with memory. For everyday gaming etc I have my GTX set at +150 on the core and +500 on the memory. I am watercooled though.
Set your cards back to default, remove afterburner and install EVGA precision X. Once done make sure your temps on both cards are below 70C or the dynamic OC will automatically cut in to throttle your cards and then just overclock core only. leave voltages at default and just raise power level to +132%.
I will bet that you will be able to raise your cores higher than +100....
