OK, I am taking it slow.
I looked at another E6850/P5N32E-SLI combo here on Overclock.net to get some ideas how to get over my hump.
Ended up with raising Vcore, 1.2HT, and NB volts a bit to the following settings in BIOS:
CPU VTT: 1.55
NTune 5.05.47.0 is the only tool that reads the same thing back to me that I set in BIOS. Everest Ultimate and ASUS Probe II as you can see from the attached pic, all read different values.
And curiously the "Voltage" reading in CPU-Z dropped from 1.312 to 1.225. Not sure what THAT means.
Anyways, I made it successfully to 3.51GHz tonight. Max core temps read in Speedfan with +15 offset applied were 63c while doing Orthos Small FFTs.
I am beginning to believe my PC2-6400 Corsair TWIN2X2048-6400C4 is holding me back. I tried booting at 3.6G for the heck of it a few times without adjusting any volts. Didn't work very well. So I'll try again another time.
A local store has "BL2KIT12864AA1065 -- Crucial Ballistix 2GB PC2-8500" for $165. I might pick up a set to see if I gain some headroom. Any comments on that memory in the P5N32E-SLI ?
