I had an Abit IP35 pro and Q6600 running prime95 stable at 400x8 but wanted to max out the FSB. I upped the FSB to 475x7, NB 1.33v and CPU at 1.45v, RAM at 2.2v since it's what Crucial recommends. When running Prime95 at the new frequency I hit a wall with the mosfet (PWM) temps. After 10 minutes they spiked to 80 degrees and a uGuru alarm started going off.
So I guess the question is how high should I have my northbridge voltage and would that lower my mosfet temps as well? Should I go for aftermarket mosfet cooling? If I do go for aftermarket cooling does that mean I need to get a NB and SB cooler as well since it's just one big heatpipe? Is it even worth it or should I just stay at a lower FSB and clock the CPU higher?
Thanks for your help.
Edit: Tried lowering the CPU voltage and it wouldn't remain stable, so it looks like it wants 1.45v at least to run stable at 3.3ghz+. 425x8 @ 1.45 still results in alarms. The PWM seems to hover right at 80, so I turned the alarm off for now until I can remove the heatpipe and add some paste which seems to have helped some other people.
