Corruption... CPU overheating... Very unstable computer... Crashing... Blue screens...

In short, it would be dumb not to run Prime95. If you encounter errors its usually because your CPU is not getting enough voltage. Voltage increases temps and with a quad you need to keep a close eye on them by using coretemp.

You should be ok if you have a shut down temperature set in the bios to have it auto shut off at a certain (safe) temp. Or a warning temp that will make loud beeping sound if it gets to warm.

Let it run for 40mins or so while your awake, if you temps are still safe they should be safe for the rest of the 12 hours. 12Hrs of overheating will rarely damage a processor anyway.

Also, make sure you guys are using v25.6 of prime95. Earlier versions do not support quads and this version is not on the official site. You should also select "Small FFT" for the test. Alot of people have the mistake and select "Large FFT" or "Blend". These tests are also good to run for a few hours after small FFT.

Another note, do NOT use speedfan with the Q6600. Its reads it wrong by default.

More VCore voltage if you can keep your temps down.

Also you may need to increase your NB or HT voltages.

Test your RAM before Priming to make sure your Ram isn't the problem. If MemTest fails after 10-15 minutes you may need to loosen your RAM timings or increase voltage on those.
