Good evening,

I have bought today a set of Dual Channel Geil 2x4GB DDR3, 2133MHz, Evo Corsa Memory Kit and i have an ASRock P55 Extreme motherboard. I have tried every option (including setting the 'Easy Memory OC' to 2133 MHz or using the XMP Profile, adding that the shown voltage is 1.65v) and in each case, the PC restarts, and when it has to start, all i get is a black screen. I have to reset the CMOS, using the button on the motherboard.

I have tried even the 1600, 1866 and 2000 MHz versions but neither works. I think i am missing something vital. At the moment, i am running on the safe 1333MHz value on CL5 Timing (if i remember correctly), but i want to use them at their full capacity.

Please help! :(

See caution#5 of your motherboard manual. Memory is controled by CPU. So it all depends what your CPU wiil support.

My Processor is an Intel Core i5 750 2.67 GHz and, as far as i know, it supports higher frequency RAM. Must i OC my processor along with my RAM, in order for it to work?

I read the Intel specifications on it ( and it says there it supports 1066/1333 MHz DDR 3 RAM.

But i have checked the Intel Core i7 2600k ( and i saw the specifications there are for 1066/1333 MHz DDR3 RAM as well. As far as i knew, i7 processors support high frequency RAM (up to 2600 MHz DDR3).

Does this mean i cannot use them at 2133 MHz? :(

Looks like you have to overclock the processor that is why they put the ( OC) behind the listed memory. Either overclock the cpu or underclock the memory I would do the memory.
