looks like 3.5/847 is stable, 1.5125 vcore, stock gpu voltage. im on 1333 memory which sucks. now i just need to figure out this things power states. im used to cool and quiet, and i dont see this as an option. my clock speeds will drop, but my vcore is staying at 1.5125
edit: nevermind i remember now. have to set the voltage option to offset instead of manual and adjust with +/- instead of just entering the voltage. there, i think ill call it good at this speed. for a black edition cpu, i was hoping for a little more than a 500mhz overclock, but meh, oh well. it seems pretty snappy on the desktop, nice and simple all in one solution.
