    2133Mhz RAM together with an i5-2500k


    Does anyone know for sure wether my rig will support 2133Mhz RAM?
    According to mainboard/cpu documentation the mainboard supports it, but the processor doesn't.
    My current RAM runs at 1600Mhz though and it seems to work.

    According to ark.intel.com not even 1600Mhz memory should work...

    I don't know.

    The QVL (qualified vendors list) for the board lists RAM up to 2400 MHz, but run at 1333. Support for high frequency RAM, but only after a fashion.

    I guess that anything over that would be overclocking. All that I can suggest is trying it (may require manually setting the memory frequency in the BIOS) and running a memory test to see whether it is stable.

    In keeping things simple, there's a standard that the industry follows where RAM speed is concerned and anything above that is considered overclocking. In the old days of the first i5/6/7 processors the spec was 1600. Today, it's 2133.

    That said, it's really up to the motherboard manufacture as to whether the RAM is capable of running at higher speeds so that's where you'd need to look. Not Intel. Again, this is the simplified version.

    Bottom line is you need to consult the MB vendor for RAM support.

    Thanks for the info! Can you go into more details though? Does this mean it doesn't really matter what intel says on their website about maximum memory frequency? I work in IT but don't do much hardware stuff so this interests me

    Thanks for the hint about QV Lists! My board is on there!



    I have just bitten the bullet and bought the RAM, i'll report back with more info when i'm done trying it out!

    The easiest way to explain this is to simply say Intel lets you overclock your RAM using what's known as an XMP Profile. The XMP profile is built into the RAM, and the motherboard manufactures says what profiles can be used. I.E. some profiles may be too high for certain boards - Example, certain MB/CPU's won't allow for 4000MHz RAM modules, while others might.

    You can read about it here - Intel® Extreme Memory Profile (Intel® XMP) and Overclock RAM
