Looks like I don't have much luck with my E8500. Since I have EVGA 750i motherboard I only have positive values to set up. Tried with 40/0/40/0 and 50/10/50/10 with 1.35V in BIOS, actually 1.336V in load at 9x445 with FSB VTT at 1.2V (1.18V Everest says) and nForce MCP 1.40V, but Prime crashed with first core after 2 minutes...

With VTT 1.2V I get -0.038V that's way i tried combinations 40/0/40/0 and 50/50/50/10 for GTL ref values...
