So, I did manage to find a semi-stable 4.0GHz (validation in signature). Ran Prime95 for ~4 hours before failing. I think I'm just gonna take my 3.9GHz at 1.387v and call it a victory.

Thanks. The difference between 3.912GHz and 4.025GHz is negligible so it's not a big deal.

I'm jealous of your unlocked cores. Mine are fully disabled.

4ghz is a magical number. You get instant +10k 3dmark06 points. Go for it man

Have you run prime95 or anything on it? I had all 4 unlocked at 3.6ghz and everything looked fine. Until I ran p95.... then it would instantly lock up as soon as i started.... Also 3.8ghz on dual cores was fine too...even ran p95 for over and hour.... then rebooted....doh! The dual core stuff is at default voltages.... i just ran p95 for 8hrs at 3.6ghz.... i think i'm gonna call that stable... i've been running the large FFTs in p95, not sure what everyone else is doing.... maybe that is overkill not sure...

Sounds like me. I can't get past 3.7GHz. Nor can I unlock my 2 cores . Not that there'd be much difference between 3.7 and 3.8, and I probably don't have the cooling for 3.9/4.0.

But 3.9Ghz at 1.387V, dam. I'm jealous.

I can hit 4.0ghz and boot into windows with 2 cores.... but.... prime95 ran for about 30secs then rebooted.
With 4 cores unlocked i got prime95 to run for a 30min with the small FFTs about a month ago at 3.6ghz. Now with 4 cores unlocked as soon as i try to run prime95 (Large FFTs) it just locks up.
I also got 3.8ghz to run prime95 for over an hour w/ 2cores... then boom, reboot!
So I'm gonna stick with the 3.6ghz for now with 2 cores at stock voltage...it runs stable for 8hrs with the large FFTs in p95.
When i had the 7750BE i hit a wall but with a little help i got it up to 3.2ghz...and that was well after I thought i was done...... so don't give up just yet... maybe your ram is holding you back..... i would try underclocking it and making sure it isn't causing the problem... just a thought

The thing that I find kinda weird is that I have to up my voltage to 1.475 to be stable at 3.7. I don't think I've seen anyone else with a voltage that high even around 3.8. Whenever I unlock the 2 cores, I can't even boot. Upped voltages across the board even and still never got past POST.
