hi there! i have the same motherboard what do you mean by disabling pll override? did you mean the Internal PLL Overvoltage? i can't see the pll override in my bios, the only override i saw was the CPU Override Voltage and it is set to 0.

Currently my highest OC is 4.3ghz and 4.6ghz HT off, my oc passed 3dmark11, 3dmark06, wPrime @ 212.731 sec but on 3dmark vantage cpu stress test i can't pass thru it always hangs up, i feel i'm missing something or there is something wrong with my settings. overclocking beyond 4.3ghz with HT on is almost impossible to me, my cpu doesn't boot nor post. I don't know how will i get a stable oc with my current rig. below is the setting i use to overclock please tell me if i did something wrong or am i missing something.

 

 

Everytime i attemp overclocking beyond 4.3ghz it doesn't boot at all, it just turn on then turn off over and over again, i have to clear cmos to get my cpu booting again. i can't oc over 4.5ghz...
