I am planning to buy a Gigibyte GA-P55A-UDP4 motherboard with an Intel Quat I5-750. I plan to use a CORSAIR Cooling Hydro Series CWCH50-1 cooler and overclock to 4GHz. I have a few open issues:
Please recommend the RAM speed point I should buy? DDR3 1600 through 2200 seem like the same parts with the OEM just changing the delay times. for example the DDR3 2000 (9-9-9-30) might be the same part as DDR3 1600 (7-7-7-24 ). Can someone clarify how the timing numbers affect th overall speed of the PC?
Also, Please recommend a process for achieving a stable 4GHz system?
