I'm not a big AMD user, but I would guess given the list of features on the motherboard's site that you have some sort of hardware supported CPU frequency control. I would hunt around your BIOS, see if you can enable that functionality, and see if that solves the problem. I will say that your MB and memory vendors sound like small 3rd party groups, and I've faced a lot of issues with those types of vendors; that's why I stick with select ASUS MBs, and Corsair or similar memory vendors. -Garrett
