Worked fine for me, 1DPC 3200C14 booted up with no issue using the XMP profile, now with tighter manual timings it's running even better. No cold boot issues, 2000% x 16 on HCI Memtest with no errors, 1.35V, 60ohm ProcODT. Can't seem to get 3333 going though and I can't speak for how this kit would have run on Summit.Based on my experience, Pinnacle Ridge performs worse than Summit Ridge with 1 DPC DR and 2 DPC configurations.
So far I haven't been able to reach 3200MHz on dual rank modules on Pinnacle, despite 3200MHz was rather easy on Summit.
And that's on B-die too.
Didn't get a screenshot of 2000% because I set the test to stop a 2000% not realizing it would close the instances and not just stop them, but ~900% below:
My old DR Hynix MFR kit -did- run worse on this 2700X/C7H than with my old 1800X/C6H though.
