haha, thanx man but the XMP profile shouldn't be the reason for trying a kit of this memory for someone like yourself who can handle a BIOS.

i was just quite surprised that any Joe-blow could grab a kit of XMP memory and when they stuck it in the Maximus Extreme it would run these sticks at spec frequency/timing, without any input at all from the end user. and not just 7-7-7 DDR3-1800 spec but PL6 and 1N as well...very aggressive but 100% stable on my setup. sure beats my experiences with EPP profiles.
