Can I put 1600mhz ram in this computer?

I currently have this motherboard: http://www.asrock.com/mb/overview.asp?Model=M3A790GXH/128M

And I want to put ddr3 1600mhz ram in it. It says that it can do 1600mhs (OC). What does this mean? If I buy the ram, will it work in my motherboard?

    It will support DDR3 1600 but not by default... Meaning you have to set the RAM to the specific MHz, Timings & Voltage, which relates to "overclocking" of the RAM.
  2. Setting your DDR to 1600 MHz is pretty easy, BIOS | Advanced | Memory Clock set to 1600 MHz, and the CAS Latency - from Auto to the correct timings {e.g. 9-9-9-24-1T}.

    Good Practices:
    Use either Certified DDR from the MOBO Mfg or Tested from RAM Mfg.
    Certified DDR - http://www.asrock.com/mb/memory/M3A790GXH128M.pdf
    Example Tested DDR - http://www.crucial.com/store/listparts.aspx?model=M3A790GXH/128M

    In addition, 1333MHz is perfectly fine for any OC 10-30% CPU OC {2.6 MHz -> 3.5Mhz}, and 1600 MHz is ideal for higher CPU OC. However, if you are planning on OC your CPU it is an unnecessary expenditure, and lower CAS DDR will be better suited. {e.g. 1333 MHz @ 6 CAS is better than 1333 MHz @ 7 CAS}. CAS or latency: Speed is the most important indicator of performance.

    Good Luck!
