Why wouldn't you run a torture test over 30 minutes? Isn't that the point?

TAT is more than a torture test. it pushes your CPU further than any other program can by stressing the cores to their maximum. I agree with gamephile.

Well that's the thing... I didn't run any CPU intensive tasks, and that's when I got the BSOD! So that basically tells me nothing at this point. I'm still clueless at to what caused the problem. Since then I went back to 2.8GHz, and whatever I do : gaming, apps, music, - the temps never go above 57C. No more BSODs yet... IF I get another BSOD, I'll go down to 2.5GHz, and lover the volts. When the CPU will start showing it's age, that's when I'll buy a better HSF, and crank the CPU up to 3.0 or above.

PS: So what is considered a good, safe temp on an overclocked e6300? What number should I NOT go above?

If you BSOD when idling or doing some light tasks, then your rig is COMPLETELY AND UTTERLY UNSTABLE and you need to check what is unstable (RAM, CPU) and bump voltages, drop FSB, or loosen timings.
And don't drop voltages, even if you downclock. You'll probably still be unstable.

True enough!!!

CPU voltage is too high. E6300 can get to 2.8 at stock voltage (1.3125) while some chips (like mine) can get to 3.2 undervolted (1.2750).

And what's the memory voltage? Mine is rated for 2.1v

And I don't think anyone mentioned this, but have you tried 401 FSB instead of 400?

I agree. Don't even think about bumping voltage until you're over 3GHz. My E6300 is running 3.1 undervolted to 1.25v (using RMClock).

Here's a few more things to try:
1. Increase FSB to around 410. There's something called a northbridge strap. The board will automatically switch multipliers for the northbridge around 400FSB, but it depends on the board. My 965PT was unstable in the high 300's, but ran fine when I bumped it well over 400.

2. Disable Speedstep. It's a good feature when you get it working, but it drops the multi to 6x and voltage to 1.16v when the CPU's idle. RMClock is a good utility for tweaking this, but disable for now.

3. Chipset heatsink. I kinda doubt it at 400, but feel the heatsink anyway. It should be just warm to the touch. I have an Antec Spotcool fan blowing on mine.

Are you sure I can go up to 410 without having to mess with NB setting, memory timings, mem volts, etc?

All DDR2-800 should be able to get to at least 430 MHz. AT LEAST. What's your memory's rated voltage? The DS3's "normal" voltage is 1.8, so adjust that accordingly.

Disable all CPU features like Virtualization, C1E, etc...

my mem's rated voltage is 1.8-2.0v. Currently at 1.8.

Still think I can go to 410-430MHz when the rated is 400?
