Can't for the life of me get CMD16GX3M4A2666C12 to work with Rampage IV Extreme

Greetings,

I'm having huge problems with getting CMD16GX3M4A2666C12 to work with my Asus Rampage IV Extreme motherboard.

Running the X.M.P profile gives me AF debug error and no boot. I have tried to run 2600MHz @ 12-13-13-35-2T @ 1.65 without the default X.M.P BCLK overlock of 125MHz but it won't boot at all.


I've also tried to lower myself to 2400MHz and trying to run 2133MHz @ 9-11-10-27-2T @ 1.65 but nothing. On 2133MHz it will POST but is not able to boot neither memtest86+ nor Windows without rebooting on itself.


Currently I'm running as low as 1600MHz @ 7-8-7-24-1T but this gives me error in memtest86+ on test 6, but not on all passes. But also Intel Burn Test tells me my system is not stable.


I did previously have a set of CMT16GX3M4X2133C9 and they managed to run the X.M.P profile with 2133MHz @ 9-11-10-27-2T @ 1.5 without any issues?



Any recommendations of how I'm supposed to get these to work? Settling for a lousy 1600MHz @ CL9 seems stupid considering the price of this kit...

Did you check to see if the memory is listed for the RIVE - here is the list and I can't find this memory listed

RamGuy,
What CPU, SB-E or IV-E
I would say it would be difficult to run that speed on a SB-E but on an IV-E it should work fine, I had a Corsair 2666CL10 kit that worked beautifully with a 4930 and 4960, blck 125. You could try one of the memory presets in the bios
