Weird downclocking problem 8800M GTX

Ever since i've installed the new 177.83 drivers, i've had a strange intermittent downclocking problem. Occasionally, when I launch a game, the clocks will only go up to 380/300, instead of the full 800/500. It's noticeable in the game's performance being substantially decreased. I had never noticed this with older drivers, although it may have happened?

I should not have downclocking problems as I have the new clevo bios that solves this problem previously (In fact, I have the bios version 1.00.09b).

Has anyone got any ideas?

Thanks!

you can try this:

go into regedit (windows key+R, type regedit and press enter)

press F3 and search for, PerfLevelSrc

chanhge the value to 2222 and reboot,

this disables powermizer in vista and makes the gou run at full clock speeds.

hope that helps.

if not there could be a problem with that driver to vista x64
