i think it can run 450, and 450 is enough for me, because even now i run at 450x8, and fyi, i didnt use easy tune, i juz use it for monitoring, hehe.. so thats mean i have to try to up the voltage right? if only that, i think ill get back to OCN if there is still problem after upping my voltage, and the voltage may vary right, so theres no recommended voltage for my 3.6ghz?
