Memory Mixing on AMD epyc ok?

[mirol]

Hi Guys I got Asrock romed8-2t with AMD Epyc 7502P and I put already 5x 32gb Samsung M393A4K40DB3-CWE But because I coudnt get another 3 I was thinking to get 3x 32gb Hynix HMAA4GR7AJR8N-XN.My question is they will work ok together not lower performace or create any issues as both got the same speeds,size and timings they only difference is that Samsung is 2R x 4 and Hynix 2R X 8.

If you look at some of the XMR benchmarks under the RAM section, it seems that there are people mixing and matching RAM. Doesn't seem to hurt the performance too much.

I could be wrong tho.

That was my main curiosity as well as to the viability of mixing rank/bank sizes. Been trying to source more ram for mine on the cheap through the used market but it's like trying to find a unicorn for a proper match.
