I was running a Q6600 2.40Gz chip fine for ages in a P5Q-E motherboard, and then decided to OC it to 3.0Ghz. Did this, and only changed AI to Manual, and my FSB to 300, and entered my Ram timings 4-4-4-12 and Dram voltage of 2.10.
The Vcore was quite high though, even though the computer was stable it was 1.41v.
So I dcecided to upgrade the chip to the Q9550 and clock up from there.
Ever since installing it, my computer has been failing Prime95 tests on standard default Bios settings!
It fails a blend test very soon into the test on 3 out of 4 cores.
I have tried to run Memtest, but keeps restarting my computer when it tries it.
