Question on RAM compatability (lemmy.ml)

I just ordered a barebones Minisforum UM690S and am currently trying to find some RAM-chips and an SSD to put in it, but apparently these RAM-chips were a bit more complicated than I had imagined.

It runs an AMD Ryzen 9 6900HX, which on its site says it supports DDR5-RAM up to 4800 MHz. On the Minisforum spec page, it also says that it uses the SODIMM form factor.

So my questions:

  1. Am I bound to 4800 MHz? Could I go for 5600 MHz and accept that I won't get to utilize the full power? Minisforum sales rep says I should get 4800 MHz, but I've also read that higher is OK, it is just wasted. In my case, I can get 5600 MHz cheaper.
  2. The sales rep also specifically stated CL40. I can't see that elsewhere, neither on the AMD-site nor Minisforums spec page. From my preferred retailer, I can either get 4800 MHz with CL38, or 5600 MHz with CL40. But not the stated combo of 4800 MHz and CL40. What are my choices here?

The specific chips I am considering are the Kingston FURY Impact-chips:

  • Kingston FURY Impact DDR5 4800MHz 32GB, CL38 (38-38-38)
  • Kingston FURY Impact DDR5 5600MHz 32GB , CL40

I am lost 🫠
