AMD AGESA 1.0.0.5C AM5 Enables Fine-grained Control Over Ryzen 7000X3D CCD Priority

ASUS began rolling out Beta UEFI firmware updates for its Socket AM5 motherboards encapsulating AGESA 1.0.0.5 patch-C microcode. This exposes several new options to end-users through the UEFI Setup Program, which gives them greater control over the way the processor prioritizes workload among the two CCDs (CPU complex dies) on 12-core and 16-core Ryzen 7000 series processors, including the upcoming 7000X3D processors.

While AMD is working to release Chipset Software updates that include “3D V-cache Optimization driver” components that introduce OS-level awareness of the asymmetric implementation of 3D V-cache on the 7900X3D and 7950X3D where only one of the two CCDs has the additional cache; these firmware-level options give users control on prioritizing one CCD over the other for workload. The firmware-level optimization is OS-agnostic, so pretty much any OS should benefit from 3D V-cache the way it was intended (where less parallelized workloads such as games are prioritized on the CCD with the 3D V-cache.
