Hi,
I'm using a P6N Diamond (680i) with a Q6600 (G0) and 4GB Patriot 800mhz DDR2 (also have OCZ Platinum 800mhz to try.) PSU is a Corsair 620HX.
I've been trying to overclock the q0, and the processor runs cool, and overclocks smoothly upto 1199fsb but the mobo hits a wall at 1200mhz. It's not the CPU since I lowered the CPU multiplier down to 8, 7 then 6 - it just doesn't like the fsb. I tried lowering the memory speed down to 750mhz in case it was an odd memory divider at 1200mhz but that doesn't help. Clearly the 1333FSB is advertised as supported, and since I'm lowering the multiplier overall CPU clock speed can't be it..
I've heard about fsb holes, but I'm wondering what I can jump to? I tried 1250, 1300, 1333.. no dice. Should I be trying random frequencies in between? Does the NB to SB speed make any diff? Should I be upping the voltage on the NB and / or SB? I tried running each with +0.05V that didn't help - there's only .2V adjustment on the NB anyways, and the SB runs at 1.5V default, so I'm not sure I should push the voltages there.
