[SOLVED] What does userbenchmark mean with "performing below expectation"? I may have issue with RAM with new build...

I just completed a new Ryzen build (yay)... well, minus the GPU as I'm still waiting for the AIBs for the 5700XT. Ran all my usual benches (Cinebench, Crystal, UserBench, etc) and I have a question about the latter. As you can see in my userbenchmark result, it looks like my RAM is performing "below expectations". So, what does that actually mean? Other users have higher OCs or something? From what I understand, the "expectation" comparison is against benchmarks using that exact same RAM kit. I would be very surprised that this relatively affordable RAM (XPG Gammix D10) would OC so well (and have more than half of its users OC'ing it above XMP).

I have the standard XMP profile enabled (timing C16, 3200MHz), and installed in slot 2 & 4 in my b450 MSI carbon AC mobo. Everything else is running stock. Looks like in particular, the RAM latency is kinda high.

Just want to make sure there's nothing inherently wrong with my RAM. I can still return the set via Amazon if I need to, but if what I'm seeing is normal here, then I'll just keep 'em. I'm just curious as to why I'm seeing the results above in userbenchmark. All other tests seemed fine.

Thanks!

Skip Userbench in the future. Try Aida64 or similar. They have a free/trial version.
Here is some ballpark figures for RAM https://github.com/integralfx/MemTestHelper/blob/master/DDR4 OC Guide.md#tightening-timings

Read speed should be the fastest, Copy the slowest.
Since you have a Ryzen 3600, your write speed will be half the speed, it's a 16-bit bus compared to 32-bit. Shouldn't really matter much. I mention it so you don't freak out.
50000 - 28000 - 45000 MB/s would be my guess for your system.

Thanks for the info. Looks like you were pretty close with your prediction : 46k - 26k - 44k MB/s with AIDA64. I guess that's normal-ish, right?

Yes. Could get better with tighter timings and maybe overclocking but that is very timeconsuming.
CPU overclocking has around 5 variables, RAM OC has 40-ish. Try to figure out which ones at fault when RAM's unstable.
