[Patch]

Try low pll. I typically use 1.5v. Sometimes up to 1.6. Definately lower than stock most of the time.

Make sure your ram isn't going too high with the multi. But you already know that.

Try shooting past a bit to jump a "bclock hole". They don't happen as dramatically as cedar mills and wolfdales sometimes did, but they do occasionally exist..

It's probably a wall though. And unlike 1366 clocking, post boot overclocking either doesn't work, or doesn't get you further.

My general experience is that SB can pretty much bench anything near its max boot cpu validation if you can keep temps reasonable.
