UPDATE: I am able to run graphics benchmarks all day @4.3...but 4.3ghz fails Prime 95 25.8 after about 30 min. Raising Vcore to 1.5 or over makes the temps shoot into the 90's...

If I go back to 4.2 Ghz...I can lover my Vcore to 1.42v (vs. 1.49) and Prime 95 runs great...it has gone about 8 hours....so that's good enough for me...temps are also 10C less at 4.2..averaging about 75C on 100% load..
