i5 750 overclocking problems

post #1 of 5
Thread Starter 
For some reason whenever i overclock my CPU's past 171 Bclock on my Asrock h55de3 they boot but fail after 2.5 passes of P95 Blend. The screen just goes black and doesn't restart. I went out and bought 1600mhz ram to replace my 1333 mhz ram thinking that was the problem. It was not.
I up the:
Vcore
VTT
PLL
DRAM

Is there something I'm missing that is not allowing me to overclock past 171 Bclock. This has happened on my i5 650 and my i5 750 now. Same motherboard.

Maybe mobo is problem? H55 isn't for high performance, however I don't have any experience with H55. and list your voltages too

careful with PLL, I prefer to set PLL to auto because it could fry CPU or/and RAM.
try this method, http://www.overclock.net/intel-cpus/...ing-guide.html
