AMD Ryzen And CentOS

CentOS 7 Comments

I have a new system with an AMD Ryzen 1600 CPU and I’m trying to run CentOS, so far without success. The only information I could find was a post reporting that CentOS 7 would crash during installation on a Ryzen system: https://www.CentOS.org/forums/viewtopic.php?ta831 .

I tried updating to the latest elrepo “mainline stable” kernel, version 4.11 (by booting from a live CD and using chroot to enter CentOS: that worked), but the system still doesn’t work properly.

I’m using CentOS 6 but I’ll switch to CentOS 7 if that will help. (But I assume that if installing the latest kernel didn’t help, neither would going to CentOS 7.)

Any suggestions? Is it known whether the next version will work properly with Ryzen?

  • The issue is likely about the chipset not being properly supported and so you will have to wait and see if 6.10/7.4 helps. You may want to check the RH release notes for RHEL 6.10/7.4 and see if support for the processor is listed there.

    While I can’t assure you that upgrading to 7 will fix the problem, the likeliness that will work is at least 50% better being as 7 is based on a newer kernel.

    I’ve installed CentOS 7 with the latest kernel from elrepo (4.11.8), and I can’t get Grub to install. I think I’ll have to conclude that it really doesn’t work with Ryzen. :-(

    Debian seems to work, so I’ll try it for a while.

  • I have a Desktop system With both CentOS 6 and CentOS 7 on it, and it works fine with my Ryzen 1700X cpu.

    CentOS 6 preexisten on the system before I upgraded it to Ryzen, CentOS 7 was installed with Ryzen. Never had any problems.

    supposed I installed or modified something at some point that Ryzen didn’t like.

    Thanks!

  • If you buy me one, I’ll create an installer that works for it :)

    Seriously though, I can regenerate an installer for ryzen if you find that a newer regular kernel works but the original one does not.

  • I’ve install CentOS 7.3 on an AMD Ryzen PC and its been up and running for a day with no issues, no hangs, etc. Lovin it!
