Hey guys, this is my 2nd option for upgrade, so I made a different topic. I found good prices on some G.Skill memory, but I need to know if they are compatible with my setup (see my signature).

The 3600Mhz kits are said to be compatible (officially) only with B550 MB & Ryzen 3000, these are the kits:
  1. F4-3600C16D-16GTZSW > https://www.gskill.com/qvl/165/168/1536220427/F4-3600C16D-16GTZSW-Qvl
  2. F4-3600C16D-16GTZRC > https://www.gskill.com/qvl/165/166/1562743659/F4-3600C16D-16GTZRC-Qvl
The 4000Mhz kits only have Intel as compatible, but these are the best price/performance for me and I would like these if possible:
  1. F4-4000C18D-16GTZKW > https://www.gskill.com/qvl/165/168/1536219105/F4-4000C18D-16GTZKW-Qvl
  2. F4-4000C18D-16GTZR > https://www.gskill.com/qvl/165/166/1536657065/F4-4000C18D-16GTZR-Qvl
Why am I bothering with these if they are not officially supported? Because my current memory kit is not officially supported and not only does it run, I managed to OC it too.

So basically I'm asking if someone has used one of these kits in combination with Ryzen 2000s and B450 MB.

I was under the impression when a Ryzen's memory is clocked beyond 3600 the infinity fabric de-clocks itself to 1/2 the memory speed.

or am I confused?

You are correct, however I would buy the 4000MHz memory for future upgrade to the 5000 series Ryzen which has potential to accept it at 4000Mhz, if not at least 3800Mhz. Also being 4000Mhz at CL18, it usually means I can use it a lower CL with lower clocks.

Is there a good article on the general topic of Ryzen and memory speeds that you would recommend? I'm particularly interested in Ryzen-G as I use it for computer builds.

Hopefully, someone will come along and post up a spec sheet with the details of which processor is good for what speed.

I do not have a good article on the topic.

I highly doubt you will be able to get those memory clocks out of a Zen+ CPU, even if they are single rank modules.

This. If you want DDR4-3600 speeds, you really need a Zen2 (*or Zen3) CPU. Zen/Zen+ top out at 3200, or 3466. I've never seen a Zen/Zen+ @ 3600, but Zen2 does that easily.

The 4000Mhz kit is for future upgrading to Ryzen 5000. If I used it now, I won't use it at 4000Mhz of course. But I can use it at 3600 with low CL settings.

You're never seen Zen+ at 3600? I'm using now a Crucial kit OC to 3600 CL18 on Ryzen 2600... it's in my signature.

Here you go, and this is actually average performance, there are better memory kits than mine:
