I was just thinking, do you have 1T enabled? because if youre running 2t that will absolutely KILL your performance, its worth like 35 FSB with equal timings

Also try running your tests in one of these 2 orders

LL DL CH DH LH N CL or
DL LL CH DH LH N CL

Some systems DL runs best first, sometimes it is LL, I run DL first
