OCing help

Well I'm trying to hit 3.2GHZ with;
400x8
1:1
vcore 1.41v
ram timing 5-5-5-15

I even bumped the nb and sb voltages a bit. I can run orthos and prime95 for hours, my last run was about 7 hours but as soon as I tried to load up firefox or opening up coretemp again the system just hangs.

Any suggestions?

well, 3.2 with 5-5-5-15 works fine now but when i set the ram to 4-4-4-12 it hangs after 5 mins or so. any ideas?

Did you increase the ram voltage to what the manuf recommends for the high speed timings? If not, that is probally the issue. Most ram takes 2.1V or so (check manuf specs for your exact ram) to run the tighter 4 4 4 12 timings but only takes 1.8V for the looser 5 5 5 15.

Please excuse me if you have done this already, was hard to tell from you post.
