KB 813945 - AMD EPYC 9554 (100-000000912) Incompatibility with Turin BIOS on ASUS ESC8000A-E13P
Summary
This article outlines the incompatibility between the AMD
EPYC 9554 processor (part number 100-000000912) and BIOS versions optimized for
AMD’s EPYC 9005 “Turin” series, specifically on the ASUS ESC8000A-E13P server
platform.
Issue Description
Users attempting to deploy the AMD EPYC 9554 CPU on the ASUS
ESC8000A-E13P server with a BIOS version tailored for EPYC 9005 (Turin) may
experience:
Root Cause
While both EPYC 9004 (Genoa) and EPYC 9005 (Turin)
processors use the SP5 socket, BIOS-level support is not universal. Some
Turin-optimized BIOS versions:
Remove
microcode support for EPYC 9004 CPUs like the 9554
Are
designed for hardware revisions (e.g., Rev 2) that do not support
older CPUs
Belong
to separate BIOS branches that are not backward-compatible
Resolution
If using AMD EPYC 9554:
Do
not flash Turin-only BIOS unless explicitly stated to support EPYC
9004.
Revert
to a Genoa-compatible BIOS version from ASUS support.
Verify
motherboard revision: Ensure the board is not a Turin-only hardware
revision.
If planning to upgrade to EPYC 9005 (Turin):
