What should I set my VCore too for this overclocking setup?

[SiliconVandal]

I've got my T-Bird running at 933MHz. I get random lockups in UT (don't know about any other games, havn't had time to install anything yet..), and I am using it because its the most "overclocking sensitive". When I get the lockup my sound loops and I can usually move around but my mouse dies, even the light goes off on the butt (explorer). I'm thinking its a combo of my broken PEP66 and not a high enough VCore. My PEP66 makes me T-Bird idle at 95ºC at 700MHz. I ordered a Taisol CGK74092 the other night, it should be here soon. What should I set my VCore too? It's set to "Auto". I want a speed that will let me have stability @933, but not add to much heat as to make it hotter, and then less stable. When my Taisol comes in im going to start running it at 1000 again. TIA!

Im running at 1000MHz right now, 7.5 x 133, 1.85 VCore. It's stable in Driver..but I havn't tried anything but it and UT. Doesn't crash much in UT (maybe every 2 hours?), and I had the VCore set to auto and now its at 1.85, so I will have to see if I still have stability problems.

i have buddys 750 t-bird running 7x133@1.85 rock solid.wwe play hours ut on lan not 1 lock up.
were also running pep66 with a delta.temps at idle are 28-30, highest 48, norm while gamming 45.
will boot 7.5x133@1.85 and play some games but locks on ut after about 1 hr.havent really tried playen with anything else to get stable at 1gig but have a feeling its in our reach.btw it wont even boot at 933 at 1.8.
