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.
Help?
