HTLink try dropping it too 600. Never tried it that fast, and the wild difference between the BUSes might cause instability, but if you are multi clocking maybe not.
should see a very small improvement on 2D benches with HTLink set very low.
Looks great though. For wprime 32M did you try running 3 threads? (seemed to give a small performance boost to me). 1024 though straight 2 threads.
If you can tune that RAM up some too it will help alot 1400 8-8-8 is weak sauce
Dunno what RAM you are running my 2K 8-8-8s I push 6-6-6 in the 1400 range. Without increase volts much.
