How many runs to you guys usually use to verify it to be CPU stable?

And memory used?

I can set about 2048, a bit more actually before the program actually tells me there isn't enough memory. Different story on my x64 though.

Manage to run 400x9 on 1.225v for 10 runs. But the temperature was showing 73 max on both cores at tjmax=100. ._. Seems like I'll need the CCF soon.

Different la bro, yours is C2Q, mine's a C2D much easier to OC. Still on stock fans ~_~. 2 cores = lesser than 4 cores producing heat ma.

I tested my system with IBT 64-bit.

400*9, 60C max on both cores

100loops took quite sometime on my PC. I think was more than 8 hours. Overnight wake up still running :S. Then again, it depends on how much RAM you allocate for testing. Those with 8GB memory system, gonna take hell of a time.

Less than 8 hours don't worry . Your C2Q definitely faster than mine.
