That RAM is great RAM and it has an XMP profile. Set the XMP profile to the appropriate value in the BIOS (on my board it is XPM Profile 1). Also set the RAM speed limit in the BIOS to 1600 MHz.
I had a similar issue with my Vengeance RAM and this is what I did. Works fine at 1600 MHz now.
Sorry, I am new to all this, but how do you enter xmp and what will you do then. THanks!
