I am employing Corsair 8GB KIT, 4 components of model CM2x2G6400C4DHX, 4-4-4-12, 2T, 2,1V version. 1.2...

I distorted in BIOS only these values...because the other standards that can be changed in AI Tweaker ( BIOS-P5Q-E) I can not discover any certification about them....

So your help is very helpful if you have some options to check.
