Problem with oc´d gtx 660´s sli?

post #1 of 4
Thread Starter 
I have evga gtx 660 sli cards. I have them clocked at 1162mhz but want to clock them a little bit more so i flashed them, changing only the volt to them from 1.174v to 1.2v then tried to clock the core to 1200mhz. A little clock as 38mhz! And running the volt at 1.2v. Then i turn on the fans at 100% and ran 3dmark 11. I got about 2000 less points before flash, with a small clock at 38mhz!! The test ran smooth and no signs the clock was to high! I even checked logg and it shows no throtling? The only option i come to think off is to maybe, flash them again and then oc the cards to 1200mhz again but maybe just raise the volt a little bit instead of to 1.2v? Maybe something like 1.190? Im clueless, cause its such small clock and the cooling is ok! And forget the memory clock i have tried to run memory at stock speed with same result? Thanks in advance for any pointers! Or if anyone can check my flashed rom if there is something wrong with it?

You should run something like Heaven 4.0 or Valley 1.0 in a loop for awhile and see if those clock speeds are actually stable.
