2X 8800 gtx SLI OC problem

[masta killa]

The problem is I cannot get it OC'ed anyhow. I tried rivatuner, ATI tools. I'm very familiar with riva. Was trying to OC it separetly of course, but each time I try to change clocks on lets say gpu1 on 3Dperformance state it comes right to factory defaults. ATI tool don't see them at all, which means I cannot move, OC anything. Looks like it dosen't recognize my cards.
Should I phisicaly remove one card then put another or something. Is this any known issue?
My system is win7 x64.

Try MSI Afterburner that allows for OC'ing each card seperately although it's built on rivatuner so you still could have a problem. If that doesn't work try GPUTool the sucessor to ATITool

Unfortunately none of them is working out for me. What do you think, it's got to be driver related problem?I'ev got the latest. Should I try older ones?

Get the 196.34 beta drivers. 196.21's are broken for OC's but the Beta's work perfectly.

196.34 beta Vista/Win 7 64-bit drivers (http://www.nvidia.com/object/win7_winvista_64bit_196.34_beta.html)
