I have an MSI Z87-G45 motherboard with 2 sticks of 8 gb ram supposedly clocked at 1866 mhz (found here on Newegg: http://www.newegg.com/Product/Product.aspx?Item=N82E16820220830), and I noticed in the BIOS that the ram was running at 1600 mhz. I tried turning on X.M.P, which recognized the memory as 1866 mhz, but when I restarted the computer it told me that the overclock had failed and it would reset to the default BIOS settings.

How can I make the RAM run at full speed?

My processor is a i5 4670 (not the K version).

Just checked, voltage is at 1.5, and when when I change the multiplier manually I just get another crash screen and have to reset the BIOS
