its not really a great oc board about 140x11 w 2700 ram samsung i get 150 w 3200 twinmos but relaxed settings 2.5 cas3-3-7 manually, auto settings are too tight keep at 1.65 v core and unlock the cpu to get the lower multis for higher fsb without big crash. higher ocs tend to crash the pci bus,cant change the pci multiplier in my bios . good luck
