D901C GPU performance issues

So my D901C with 8800m GTX's in SLI have kinda been dropping the ball during games for the last couple months. I have noticed that the cards clock speeds don't match up except while the system idles. I am currently running Dox 195.62 drivers that I installed 2 days ago. After installing them, and restarting, I enabled SLI, which did not tell me I needed to restart, I tried Dragon Age Origins and it ran perfectly on highest settings, and nvidia monitor showed maxed clock speeds for both GPU's. However after I restarted the system, its back to only one GPU showing max speeds, while the other only goes to about 50%.

This seems to be the case for any game I run, including Just Cause 2, Dragon Age Origins, and Assassins Creed 2. The clock speed settings under Nvidias control panel are the correct factory defaults.

Im running Windows 7 64 bit btw. I originally noticed this problem while running nvidias official 197.16 drivers, and switched to Dox 195.62 hoping to fix it.

 

If I remember correctly, it happened to me (M17X-R1 with 280M SLI) after installing the 195.62. I switched to 195.91 or .82, don't remember exactly, and it fixed the issue. Dunno, try other drivers, the only thing I can tell ya.

 

Thanks Aikimox. I'll see if either of those versions help. I've tried about 6 or so since posting this, but not those ones.

 

The same problem happened to me with Dox's 195.62 driver. The only way to repair it was a fresh format... I've stuck with Nvidia's official drivers since then.

Edit: For the record, different driver versions (including the 'best' 186.81) did not resolve the issue. I was forced to re-format and re-install Windows 7.
