Asrock x470d4u RAM compatibility

Solved

I was wondering if someone with the Asrock x470d4u and ECC memory (32gbx2 preferably) could share what RAM they used and if anyone has had success with these Crucial ECC Memory sticks

I recently put my build together and it wouldn't post, so I assumed it was a BIOS and Ryzen 3900XT issue. However, I'd have to wait a while for a Zen 1 or Zen+ CPU, so I decided to troubleshoot other issues first. Once I switched the ECC RAM sticks out with some regular old RAM, the computer posted.

Now I'm wondering if my sticks of RAM just aren't compatible with the motherboard, or if I got some odd RAM (the RAM I got is similar but doesn't match the picture from the newegg link)

Thanks!

You need unbuffered ECC RAM. If the RAM you have is registered (buffered) like the RAM in your link, then thats why they aren’t working; they are not compatible.

No problem. Just look for UDIMM ECC sticks from Crucial, SK Hynix, Samsung, or Kingston and you’ll be good. And make sure the timings are compatible.

These are on the memory QVL list for your mobo:

If you want 32GB sticks then they should be a solid option.

I made the same mistake when building my server on that board :)

I used two Kingston KSM26ED8/16ME from Amazon, 2x16GB ECC for 32GB total, with a 3700x CPU.

The IPMI interface can be used to flash the BIOS over the network, without having to be able to boot the system, from the remote management console.

I was looking at those sticks just earlier. Thanks for the suggestion.

I'll need to read/watch more videos on how to use the IPMI interface. I'm pretty new to the server hobby, thank you for the knowledge!

If you are still shopping I use 4x of these on the board with a 3900x: https://www.amazon.com/gp/product/B07YXBHXN7/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
