Installed 4 X 8 GB Flare X 3200MHZ CL 14 in my gigabyte X570 prowifi Ryzen 3800X build.
Runs stable with XMP enabled.
Checked mulitiple system analysis tools, all show expected frequency, timings, command rate, voltages etc.
However, performance is pretty bad. Benchmarking on UserBenchmark website says my RAM is performing significantly below expectations after multiple runs, no other significant programs running. Multicore bandwidth was 34.4 GB/S and singlecore was 30.7 GB/S. Latency was pretty typical for the kit and not a concern.
Now, looking at other benchmarks, this is a recurring theme, the same kit of RAM is performing below expectations on every 3600, 3600X, 3700X, 3800X build ive seen. Only one 3900X benchmark i saw looked normal.
This is contrasted to the 2700X which generally scores 40-45 GB/S multi and 35-40 GB/S single. And obviously the threadrippers with quad channel score quite a lot higher.
This also affects X470 boards running 3000 series CPUs too. And it affects 2 X 8 GB configs as well, bandwidth RAM speeds are much lower with ryzen 3000 series CPUs than 2000 series with the same RAM, whether 2 or 4X 8GB.
Looking at my passmark RAM benchmark however, the scores seem pretty normal.
Im thinking is this a bug in the UserBenchmark software, is it just not configured to benchmark RAM with Ryzen 3000 properly yet? Or is this an issue with immature BIOS or something else?
