Hello everyone!
I've been using my Xeon X5460 on the P5Q Deluxe for some time now. It's been running at 4GHz stable since it arrived, and it performed well on Prime95 for over four hours. I decided to push its performance further by overclocking it to 4.3GHz, but stability issues arose. Sometimes my CSGO would crash unexpectedly, though not always. Instead, I encountered BSODs (pfn_list_corrupt) while browsing with Chrome. The Vcore seems fine; I think it's possible that running at 4GHz stable doesn't require a large jump to 4.3GHz. I've tried 1.37V and 1.34V to confirm, but results were consistent. I'm also experimenting with adjusting the northbridge and southbridge voltages, as well as using only one dimmer instead of four. My specs include an Xeon X5460 E0, Asus P5Q Deluxe, and four Crucial 800MHz 2GB dimmers. Here are some screenshots of my configuration. Thanks!

It's a $15 CPU purchase, but keep a spare on hand.

As long as temperatures stay under control, I recommend letting the smoke dissipate.
I’ve disabled one Prime95 instance and run three threads, which puts the CPU under 75-80% load. This performs well on Firestrike and Heaven benchmarks. You might try a more accurate voltage setting this way. I haven’t experienced any crashes during benchmark tests with that configuration.

i feel really foolish at the moment.
it was the vcore, and it seems stable at 1.42 volts (at least for now). it used to crash after a few minutes of prime95, but it's been 20 minutes and it's still running well.
though i won't run it in this way. 1.42 volts is way beyond my comfort level.
sorry for not doing enough research before posting...
