I really need a new mobo i think. This DS4 & Q6600 does 3.6GHZ with 1.35V (10hours of P95 stable) but it just wont do 3.8GHZ, even had the Vcore upto 1.6V, mch & fsb to 0.2 and it still reboots.
Mobo may be faulty though has i got a noise like a cricket coming from the cpu which gets louder the higher the clock/Vcore goes

So, whats the best O/C board for these quads? money doesnt matter aslong as i can run my DDR2 in it
