reach out to support to get a beta version of the bios, that fixed it for us.

I'm surprised you are having the issue with a 4004/7000 cpu, I thought it was due to the new gen 4005/9000 cpu.]]> Tue, 01 Jul 2025 05:17:03 +0000 https://forum.asrock.com/forum_posts.asp?TID=29599&PID=197977&title=c5-code-on-b650d4u#197977 https://forum.asrock.com/forum_posts.asp?TID=29599&PID=197976&title=c5-code-on-b650d4u#197976 Author: intuego

We have 5 new B650D4U boards 2 from vendor A, 3 from vendor B. Vendor B boards have this C5 issue after upgrading bios to 20.05 in order to support Epyc 4005/Ryzen 9000.
Swapping the memory from from a functioning A board to B boards, the issue appears inherent to the batch of B boards.


If anyone has resolution/other on this, it would be appreciated.]]> Sat, 14 Jun 2025 09:50:27 +0000 https://forum.asrock.com/forum_posts.asp?TID=29599&PID=196463&title=c5-code-on-b650d4u#196463 https://forum.asrock.com/forum_posts.asp?TID=29599&PID=195866&title=c5-code-on-b650d4u#195866 Author: mariusleu
