I have E8400 on a p5q-em MB with ddr2 800 mhz ram. I've overclocked cpu to 3.6 by raising fsb speed to 400 mhz and multiplier to 9. I set Vcore to 1.14 and have run prime 95 stability test for a couple hours no problem with advanced mode round off checking enabled . Cpu cores temp only reach 65c. Should I go down to 1.13 vcore and run prime 95 for ten minutes. And if stable go to 1.12 and test prime for ten more minutes and if no errors and keep going down like this until I fail a ten minute prime 95? And at that point raise Vcore and increase my prime95 test duration period for stabilty? Is this a good method? What increments should I be raising and lowering Vcore by?.

how do I properly adjust/lower Vcore?

What cooler are you using? 65c at load for 3.6Ghz is a tad high.
Other than that I would say you are on the right path. Might try using Intel Burn Test utility instead of P95 for 10 minutes. IBT puts more stress on the CPU in a shorter timeframe, and you'll actually see higher temps. But it provides a quick stability test. Keep lowering vCore, run IBT for 10 passes. Wash, rinse, repeat until it's unstable. The bump vcore back up for stability.

Well those temps are quite high. I'm running an E8400 at 4.05GHz with 1.255 volts and my load temps (aka 20 mins of intel burn test) are 54C and my load temps with prime95 are 47C.
I'm running a nt06 silverstone heatsink with a fan attached to underside of heatsink blowing air into my PSU which is mounted flush with top of nt-06. I don't expect great speeds, I went for the less noise option.
So Intel Burn Test utility is better for fast tests, thanks. Does it matter I'm using vista 64 bit? How does this program report failures? So I continue to lower my vcore by one tenth of a decimal point at a time say from 1.13 to 1.12 until I see instability within ten minutes of IBT. At that point should I just raise my vcore up one tenth of a decimal point and continue to test for up to 24 hours with prime 95 for final stability? Or should my first raising of value after failure be of a greater amount than just one tenth of a decimal point? Thanks; so to recap- IBP is better for quick 10 minute stability test, but prime 95 is still better for 12-24 hour long term stability test right?
