Ryzen RAM

[Eric1987]

Gonna upgrade to 32GB for my Ryzen 1700 and I am curious what RAM is best compatible and has RGB? Haven't been keeping up. I have the latest bios x370 prime pro.

Bump just looking for the best RAM for my Ryzen. Is it all normal now?

I would've thought Gskill Trident Z DDR4-3200 C14, but I don't see it listed in the Prime Pro QVL - as a matter of fact, I didn't see anything above 3000 listed for all 4 DIMM slots. Samsung B-die is probably you're best bet.

Get 4x8GB stick instead of 2x16GB.
Works significantly better and at higher speeds on Ryzen.

What is that max memory speed allowed when populating all 4 dimm slots with Ryzen these days? This part still confuses me as well as I see alot of people saying they use 3200Mhz, but then there are people claiming 3600Mhz and even some say as low as only 2666Mhz.I know using all 4 dimms puts a strain on the memory controller so are these people just using 2 dimms and not all 4??

You're going to take a speed hit whether you use 4x8Gb or 2x16Gb, but I think the 4x8Gb route is generally safer.

If I wanted RGB RAM for a Ryzen system, I'd get the best TridentZ stuff I could afford. Plus that would potentially put you in a good position for a Pinnacle Ridge upgrade down the line.

3200+ support depends on motherboard, CPU IMC, and quality of the RAM used. Your best bet to achieve 32GB 3200+ is with 4 DIMMs of RAM that use Samsung B-die ICs.

Example of when I first got 3200 CL14 4x8GB working on a Gigabyte K7 (IIRC it required a few more UEFI updates before it was stable out of the box without tweaking):


Unfortunately, RAM prices have almost doubled since Ryzen's launch... so B-die will be prohibitively expensive.

2133MHz with 2 DPC single rank configuration, 1866MHz with 2 DPC dual rank.
There is generally very little difference in the frequency between 1 DPC and 2 DPC single rank configurations in terms of the maximum achievable frequency.
Dual rank DIMMs are generally a major PITA on Ryzen and even 3200MHz on them is rather hard to achieve, regardless how good the DIMMs are.

16GB DIMMs no doubt have a better resale value, but if you want to use 32GB of RAM on Ryzen at high speeds I highly recommend you to get 4x8GB instead.
