overclocking results in lower 3dmark score?

[gotkilled]

I have the gigabyte ds and have overclocked my e6300 to 3.15 7x450 and is stable in othros prime and occt. For some reason, my 3dmark score gets cut in half to like 4k when I easily get 8k normally. When I default it back to stock speeds 266X7..the fps n 3dmark05 go back up again. I have the PCIE locked to 100mhz and pcie to stock.

PS I'm running vista.

any ideas?

How hot is your CPU getting underload, it might be throttling. Although i wouldn't think that it would affect it that much, anyway. Try running 3DMark06, if you can, it's less reliant on the CPU and compare your stock and overclocked scores.
