I've found several articles saying that most CG Clawhammer CPUs
OC up to 2.5 GHz on air. I'm not having that kinda luck watercooling and I have a CG ClawHammer.
And, to answer my own question from above. Running a divider on your memory shouldn't affect performance on A64s cause the memory controller in on-chip so it's already running at a divider. Makes sense cause CPU-Z always shows CPU/9 as the divider.
