The 765 showing is the max I know for sure is stable. I thought I had 785 stable, but it crashed in a mess of artifacts playing L4D. Survived furmark and OCCT just fine, which is what prompted this.
I don't know exactly what the issue may be, unless I just got an extremely poor chip for overclocking.
I think you just need a beefier power supply.
Seriously though, been so long since I oc'd a video card. No idea, but from what I'm gathering you should be able to hit 800 without much difficulty.
