Help Overclocking I5 750

Hi,

I have got my cpu to this settings in minutes, very stable with low temps i think. But i cannot exceed to 4 Ghz and i dont know why.

Motherboard is Gigabyte P55 US3L
Ram OCZ 1600 Mhz Platinum Edition 2x2 Gb

Cpu Is at 3.8 Ghz
FSB is 181 x 21 Multiplier
Ram Multiplier is 8
CPU Vcore is 1.1875 Volts
Ram 1.64 Volts
The rest are on auto

Turbo Boost is disabled.

I have tried 191 FSB with a vcore of 1.2 but the prime 95 test fails within seconds.

Could you please give me some suggestions, cos i think the temps are low and can overclock a bit more.

What do you guys thinks.

Thanks

The vcore sounds low, i would keep bumping that till you get stable at 4Ghz.

Both good guides and suggest voltages for the i5 750.

Yeh, the voltage is probably what is causing it to fail. Try going for around 1.25v, thats actually still pretty low voltage so there shouldn't be any harm in that

Yeah but what are the temps i should get at load, i mean something reasonable, for 24/7 use
