How to increase from 1333 to 1600?


I have a pair of Corsair Vengeance (CMZ8GX3M2A1600C9B) for a total of 8gb (2X4). The packaging says that they are supposed to be @ 1600 mhz, but in my bios it shows that they are at 1333 mhz. Should I increase that to what the package specs say or should I not touch it? If so, how?

Thank you.

  1. Need to find the Memory Timing section of your BIOS and change the profiles to XMP profile 1 and if it doesn't automatically change RAM to 1600, try manually using the slider to set RAM to 1600.

    You probably wanna leave those settings as they are because the timings are also decreased in the system default settings for ram. So turning the frequency to 1600MHz and increasing the timings will actually won't speed up your system too much the speed boost is very little.

    Either way if you still wanna change it
    Open bios DEL key(most probably) during the post
    Open MB Intelligent Tweaker
    System Memory Multiplier
    Set the multiplier to 12.
    In DRAM Timing Schedule chane the timings to the timings specified on your ram card.
    I think the timings are 9-9-9-24.

  3. 1600 requires enabling XMP in BIOS. 1333 is safer but may still be faster than recommended for the RAM chips.
  4. Thank you. I won't be touching those specs. Leaving them alone is the best!

  6. You will not damage your system by enabling the XMP profile to get full use of the 1600 speed that RAM was designed to run at....Your board supports both speeds without overclocking.
