Apparently, only the Ryzen 5 7600X is affected, and not just any: only those equipped with a couple of CDDs. Most motherboard manufacturers have removed malicious firmware from their websites; a new one will arrive in a few days.
AGESA firmware 188.8.131.52 (SMU 84.79.204) will likely disable one of the Ryzen 5 7600X CPU cores, according to information shared by leaker chi11eddog. The latter tweeted the discovery following the recall of the incriminated BIOS by MSI and ASRock. Both of these brands have removed the firmware from their X670 and B650 motherboard pages, but it is still available on some Gigabyte 600 series motherboard pages. Naturally, avoid downloading this version.
The error will only affect the Ryzen 5 7600X; no more, with only two CCDs. Most instances of this processor have only one CCD, which is enough to fill its 6 cores / 12 threads. However, there are a few dual CCD Ryzen 5 7600X, leftover Ryzen 9 7900X and Ryzen 9 7950X. AGESA firmware 184.108.40.206 (SMU 84.79.204) will combat the Ryzen 5 7600X dual CCD: it disables one of the CPU cores, Core0, according to chi11eddog.
In December, buyers abandoned the Ryzen 7000
New firmware is being prepared
AGESA 220.127.116.11 (SMU 84.79.210) is in preparation to address this issue. If you’ve downloaded the new firmware and have a Ryzen 5 7600X, make sure it’s working properly; otherwise, you can revert to a previous version.
Remember that AMD expanded the Ryzen 7000 family at CES 2023. Non-X Ryzen 7000s will go on sale starting tomorrow.
