Upon booting my system earlier i was met with an overclocking failed message, put everything back to default in bios which allows the system to boot and enter os fine. However, when trying again to set the ram to its XMP profile, upon rebooting after saving in bios i get the same message. Ram is a 16gb quad channel gskill ripjaw 4, c15-15-15-35 1.35v kit. Heard a few rumours when i first went X99 that some non oc socket boards had issues with ram running faster than 2666mhz, i did have a few at first but updating to a newer bios sorted theese and the kit has up until now ran fine at 3000mhz. Just had a look too on the msi website where this memory kit at 3000mhz is stated as being supported by the X99s mpower board.
