CFD-Multiphysics Benchmark for x86 and ARM (Windows/macOS/Linux)

You’re running an AMD 9950X right? Yeah, just tuning my RAM alone got me a 30% faster score from 36m13s down to 25m30s. A little PBO didn’t help any more though. This benchmark is pretty heavy on memory i/o.

@gluon-free , as lemma mentioned in their insightful comments in the other thread, even a little RAM tuning can provide significant uplift for some workloads without pushing speeds into potentially unstable territory.

I’m guessing you could probably get at least 10% improvement by

  • confirming 1:1 uclk=mclk if it isn’t already
  • fabric clock at 2000MHz if it isn’t already
  • snug up tertiary/secondary timings a little
  • leave primaries mostly alone at your CL32 XMP profile

I’m curious the results if you decide to tune RAM. Thanks and cheers!
