But I don't check the speed at 660Mhz core.
Memory limited to 975Mhz @ 2.2V.

@ madshrimps said : OVP is only for GTS not GTX ??
I think the problem is either

1) not enough cooling for your video card
2) your GTX is just not going to go over your current setting
3) make sure your shader speed isn't going too high b/c that can cause instability too

Other than this, I have no clue.
