hmm, I let my testbed run through the night, everything is crispy new. And only getting 43.7k PPD on a 6900 tpf of 27min. (with an overclock of 5ghz) Something feels off.
-edit- messed with ram slots and timing, got a tpf for one frame for a little over 50kppd, I will post results after a few frames. Hopefully that was it.
