RAM won't overclock

I have a fairly good system which includes an MSi Mpower Z87, an Intel 4770K and 2x8 GB of Corsair Dominator Platinum 2400 MHz.

My problem is that I can't get the RAM to list as running at 2400 MHz.. Not even the 1200 MHz you'd expect from a dual-channel setup.

I've enabled the XMP profile and, be it the BIOS Memory-Z or CPU-Z, it's always listed as 667 MHz.

Does anyone know what might be going on?
All replies are appreciated.

which one do you have exactly? http://www.corsair.com/en-us/memory/dominator-platinum about that o/c again if you are having auto voltage ensure you are at 45x100=4.5ghz(also mind that auto voltage results in ridiculously high voltages and temps.)are you sure you are 100% stable? if all seem right care for a bios update.

cpu z shows 667 so it is actually running at 1333mhz. also for running such high speed ram you may have to o/c the cpu. a minor increase at 4.2ghz will be enough!

ok try by manually setting the speed cl timmings and voltage.also is 4.5ghz as a result of increasing the multplier only or the bclk bus speed also? increasing the bclk also further increases mhz of ram and stresses the memory controller.

To get the 4.5 out of the CPU I only adjusted the multiplier.
I tried starting with XMP off and only setting the frequency from default 1333 to 2400 and to 2000, did not work.
I tried to implement the XMP settings (frequency and CL timings), but with XMP off, did not work.
