Default Q6600 ; Hitting a wall at 2.85Ghz, no voltage helps.

Hi guys,

I just set this rig up, took most of my other components from my old X2 setup. I'm overclocking it, but everytime I go past 2.85Ghz (1245FSB, 9x Multi), it just doesn't boot to windows. The wall is so extreme that I can do 2.85Ghz all voltages on auto (1.24vCore) and that works fine with prime. But if I dare go 10Mhz over that, no matter what voltage all the way up to 1.48v, it just doesn't make it to login. SPP voltage, or FSB voltage up to 1.5v, just doesn't matter at all.

Temps are okay, watercooled. I'm wondering if it's my PSU, I can't believe it though, because there are a few others with this PSU and Quad systems. My 5v+ is on 4.93v though, the rest is all well over 12v+ and 3.3v+. I don't know what to do. It's not a poor powersupply, tried switching the leads around, thinking rails wise etc, plugged in all cables, 8pin and molex aswell. Nothing changes.

Apart from that everything is adjusted properly in the bios I think, ram is unlinked from the FSB, at 800Mhz etc, no problem there.

I've been overclocking for a couple of years now, but I'm a bit baffled by this.
