Solved Crucial Ballistix Tactical 1866mhz 2x4GB defaulting to 1333mhz - how to I change? Tags: Memory Evo Crucial Last response: February 13, 2014 5:46 AM in Memory Share abuja_limey February 13, 2014 4:57:59 AM Hi all, Unfortunately my M5a97 EVO r2.0 mobo will only recognise this memory setup at 1333mhz. I have upgraded to the latest ASUS BIOS (2201) but that hasn't resolved the problem. Would the solution be to manually change it in the BIOS? I would know how to do that, but I am a complete beginner when it comes to voltages/timings.

Share abuja_limey February 13, 2014 5:40:45 AM Thanks, that did the trick! There was no simple 'change to XMP setting' though. For those wondering how to do this on the ASUS BIOS, I found this: "1. Set「Ai Tweaker」-->「Ai Overclock Tuner」to 「D.O.C.P.」 2. Set「Ai Tweaker」--> 「DRAM O.C. Profile」to 「Profile#1 or Profile#2」，and then press F10 t0 save and exit. " In my case there was a Profile#0 that I used. m 0 l Can't find your answer ? Ask ! Get the answer ubercake a b } Memory February 13, 2014 5:46:06 AM Glad to hear you got it working. That setting is always somewhere in the BIOS on most capable motherboards whether it's called XMP or DOCP. m 0 l Can't find your answer ? Ask !
