Can't XMP OC my Corsair [CMZ8GX3M2X2133C9R]

I can't seem to be able to overclock my memory through X.M.P in the BIOS. I click on the XMP to enable it and select the relevant profile 1. When i save & Exit, during the reboot i get an error. "Overclock settings were incorrect or something and press F1 to resume set-up or F2 to load defaults"

Now some people say that this might be attributed to the fact that i didn't OC my processor so i OC'd my 4770k to 4.6Ghz (1.22v)and then tried the XMP settings. Again i get the same error. Now what is the problem? I know it is the RAM that is causing the problem! also this particular RAM is rated to run at 2133mhz at 1.5v and iall i'm getting is 1333mhz!

thank you.

  3. XMP profile isn't an overclock , it's a predefined optimized setting.

    Ok based on the Model # you have a single 2 stick set correct? 8GB total, XMP enabled and an OC of 4.6. If the above is correct let's drop multiplier to 43 for the moment, then since XMP is enabled check what freq is showing, should be 2133 if not manually change, next what timings are showing for the DRAM currently - should be 9-11-10-30 (if not manually change to these), next let's look for CR which is Command Rate or Command Timing (something similar, it will either be a setting of 1 or 2 followed by a T or N - so should appear as 1T, 2T, 1N or 2N - regardless of the letter it should be a 2, next find DRAM voltage should be 1.5 to 1.55, if so leave as is, if not change to 1.55 and finally there will be an area of advanced timings to look for, there will be a lot os odd things like tRC 31,, tWRD 7, etc look for tRFC and see what it is, believe should be around 128, if not leave as is and let me no....if it still has problems can try running the tRFC at 128
