The scores posted were 440 / 1100 respectively. I just did a bench before I posted. It is a mild overclock at best, I just ran a benchmark before I replied to this and at 400 / 1063 and 3dMark06 score 3750 ish.
The core clock produces the most noticeable change in score, my core maxes out at 490 on 3dmark05 (7900-8000 @490/1300) and 485 on 3dmark06 (4200 @485/1300). Those are benchmark stable, but I don't play games at those frequencies since I live in Los Angeles and the ambient temps here are roughly 90F+ lately.
I got my 92.97 is from X-Treme G's MobileForce M4 Drivers. If you download their drivers, you won't need to download the modded .inf because it is packed into the .exe instead of the usual .inf
You could also you laptopvideo2go.com to get the 97.92 drivers as well as stated above. I've tried a lot of the 100+ series drivers, and while some do have slightly better results (at stock), they seem to lock the clock speeds at stock settings.
