I've been running my Q6600 at 3 GHz now for around 9 months. Stability has been fine.
I thought I'd try and get a bit more out of it, and started raising the FSB and CPU core voltage.
I've got to the point where I seem to be stable (not 100% confirmed, but prime for a couple of hours is ok) at 3.158 GHz (FSB at 351, CPU Core Voltage at 1.264V under load, multiplier is at 9). Temps under load are up at 69/70 C, which is about 6/7 C higher than temps at 3 GHz.
If I increase the FSB in the BIOS to 355, the PC hangs when it's checking the RAM. I've slackened the timings to 5-5-5-15 and rasied the RAM voltage to 2.1 (using 2 x 2Gb G.Skill PC2-8000), still hangs at same point on my LCD poster (motherboard is Asus Maximus Formula (X38)), testing the RAM.
I nominally increased the NB and SB volts from the 1.36V and 1.07V they were running at, but no change.
Not sure what to do next to get my Q6600 to somewhere near 3.4 GHz (on air). I'm sure it must be possible.
Any advice ?
