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.
 
I have mate, still no joy. Looks like a new ram kit is required. Had a similair issue a while back on a Z87 system. Kingston ram kit wouldn't work at xmp either. Had to rma it.
 
3000mhz is not always working on non-oc boards. I said this myself many times. What I say is not rumours it's after testing.

You can try pushing cache and SA voltages to help your issue sometimes this works and you regain stability.

System was ran mostly at stock, board. CPU and ram bought from Hivizman who assured me that 3000mhz was ok on this board, which I've ran since I bought it last year. Board states compatibility with ram upto 3200mhz. Had the CPU clocked at 4.5 until last night, but now xmp refuses to work with the chip at stock?
 
Will be interested if you solve this. Got exact same issue wih 3000 MHz kit now also. Dominator platinum but on x99 E-WS. Ran at 3000 MHz fine for months, now refuses to boot when I use the XMP profile. CPU has zero issues in reaching good overclocks still and this problem persists with CPU at stock or oc'd. Also has up to 3200 MHz support on ASUS's site.

Interesting, I thought all Asus boards had the oc socket, so high cache and memory speeds are standard on theese compared to non oc socket models?
 
Popped the battery out of the board this evening, ram now back running at 3000mhz? Cpu at defaults, had it at 4.5ghz up until this issue happened. Odd thing is though i had no errors such as bsods, black screens system freezes etc. Had the machine on alll monday night just browsing the net, shut down as normal only for this to appear last night upon the first switch on since monday. Definitely a strange one.
 
Rebooting fine all last night, but I've bought a pack of batteries just in case. System running ok at stock, will try it with a cpu oc too.
