AMD Zen 5-series CPU bug prevents iLok working

[mdyde]

PACE have notified us that a bug has been found in the microarchitecture of the AMD Zen 5-series CPUs that were released in July (branded under the “Ryzen 9000”, “Ryzen AI 9”, “Ryzen AI 300”, and possibly more names), which prevents any iLok-licensed products from working (including Hauptwerk).

They have reported it to AMD and are awaiting their response (hopefully a CPU firmware update to fix it).

In the meantime we'd strongly recommend avoiding buying those particular CPUs for use with Hauptwerk (or for use with any other iLok-licensed products).

This warning came at a good time. I was already considering upgrading the current Intel i7-13700H-based MiniPC to an AMD AI-R9-8945HS-based one, for performance and lower heat dissipation. So, I will wait for the outcome of this question to properly assess the possibility of this update.

Thanks, abaymajr.

A brief update: PACE have informed us that AMD currently expect to have a new BIOS version that fixes the problem ready for public release in early November.
