yeah i had a B3 6600, only clocked up to 3.4, hence no need to really change anything
Motherboard voltages when overclocking Q9650

Ok...
small fft runs stable for hours. blend crashes after an hour. do I need to loosen timings from 5-5-5-18?
cant go any slower on ram speed

If your ram is running faster than it's rated speed then relaxing timings may get you sorted. For a 45nm quad and high clocks PC2-8500 is the best option though.
Nah, never worked.
Tried it just, 7-7-7-21, blue screened after 5 mins on blend.
Weirdly 5 passes on intel burn test (on maximum), passes.
Ran small fft all day while at work, no crashes.

My old Q9550 would pass IBT/Linx no problem at 4.2Ghz but would then fail Prime. Linx/IBT is ok for doing a quick test while you find the maximum clock but Prime is best for ultimate stability. Small fft's is mainly the cpu but blend is ram and cpu which is probably why it's falling over. New ram or settle for a lower overclock i think.

Try running memtest and see if that passes?
I can't get my P5Q-E to boot Windows at 500 FSB even when lowering the cpu multiplier and I've checked my memory up to 533 using a memory multiplier and it's fine so it's looking like the board isn't capable which I find hard to believe.
Anyone know what settings need changing to get 500+ FSB on the P5Q boards?
I've changed the obvious like VTT, PLL and NB but no combination of changes work so I suspect I'm missing something.
For reference with a Gigabyte P45 board I can boot into Windows and it runs prime at 533 FSB when the CPU multiplier is lowered.

Some boards just can't do it. It's luck of the draw.
well, after a few more notches on vcore, i think im close to stability. very high though, 1.3875 in the bios setting, with no crashes in prime for 10 hours.
might start to try and drop the board voltages now.
