I think I just got unlucky with the CPU. Still not entirely stable, so I dropped down to 3.8Mhz (19.0 multiplier) @1.45v.
Try 206x19.5 and 1.45v

Yea the C2 965 sucks for me. I have to keep it at 1.5v to keep it stable at 3.89ghz. Cant wait to move that pos to server duty in June. You may just have a bad cpu. Most people I saw with a 970 got theirs to 4.1 at 1.465 stable but not all CPUs are exactly the same.

Definitely try a higher base clock. Something like 250 MHz x 16. Temps obviously aren't the issue here, so something else is holding you back, and I'm pretty sure it's not the CPU. Keep HT Link frequency at or below stock of 2000MHz for now and same goes for NB frequency. Keep RAM at stock frequency and timings.

Oh, and make sure Spread Spectrum is off and so are Cool n' Quiet and C1E in your BIOS.

Have your tried increasing your CPU-nb voltage? I couldn't get my 1090 past 4.05ghz stable till I bumped up my CPU-nb voltage.

Hmmm I thought I was stuck a 4.0Ghz cause anything about 20 multi and I get a BSOD. I will have to use this advice and try upping the BLCK in combination with the multi.

So, I was reading this thread, and saw that you can't go past 4,0GHz.
I got a Phenom II x4 970 BE and I got past 4,3GHz with ease. Stable OC.

Here's my CPU-z stats and stuff. http://valid.canardpc.com/show_oc.php?id=2108943
