Just finished a new build using a asrock x570 Taichi, a 3900x and 64GB Hyperx Predator Ram (this kit)
Turning on XMP got me up to these numbers: https://www.userbenchmark.com/UserRun/23798776
but latency is still quite high at 73.2ns
SC Read 27.2 GB/s
SC Write 24.6 GB/s
SC Mixed 38.6 GB/s
Latency 73.2 ns
Is that to be expected with 4 sticks of memory or can I do better?
