I think I'm done tuning my 6000 MTs profile, though i could probably lower it more. I want to do a 6400 next, what are my chances of getting good results there?

I don't know what's up with my ram write speeds, need help with figuring this out. I will provide more system info as needed.

Generally help me spot 'wrong' timings. At the very least i know that I should increase tRAS.
