8800gt Problem

I was messing around with the driver settings in riva tuner even though I didnt really know what I was doing (probably shouldnt have been changing the settings >_<) but anyway I noticed that the memory clock had a little yellow (!) next to it and was all the way to the right.

But because I have the 8800gt OC from BFG which comes OCed with the memory at 1800 I knew it was fine. I went ahead and tweaked the core clock and shader clock a bit just to experiment.

When I was done I clicked the small arrow in the Drivers settings and chose the reset driver settings to their default values icon and my memory clock went down to the stock 900MHz and the slider wont let me put it back up to 1800 MHz (it stops at 1350).

I tried uninstalling and reinstalling the driver did nothing. Then I tried doing a system restore to earlier in the day which also didnt help. Any assistance you guys could provide me with would be greatly appreciated.
