I did a few quick tests;

2.9Ghz, +0.025mV, -4/-4/-4/-4
Core 4 errors immediately in Prime Blend

3Ghz, +0.025mV, 0/0/0/+2
Prime 95 crashes (as application, not errors)? Happened twice in a row.

3Ghz, +0.025mV, +2/+2/+2/+4
BSOD's after a minute in Prime Blend

lol, wut.

I noticed the 4th core is the weakest, but Ill play around more tomorrow to figure out whether the 2nd test I did is a matter of too low Vcore or wrong ACC settings or something.

I read from anandtech that stock value from SB600 the ACC was -2 ~ 0. With SB750, as you know, you can go from -12 ~ +12, with - going into the less Vcore direction and with + higher clock direction. Interesting.

Could someone btw comment on my tests? BSOD shows easily the settings were crap, but what about the 2nd? It actually never happened to me that Prime crashed as a program, always either error or BSOD Does this means more Vcore? Or is that impossible so I should be looking at ACC?

Thx in advance and gdnight.
