AMD: Update Your Bios Against Burnout, ‘Regular’ Ryzen 7000 CPUs Are Vulnerable Too – PC – News

AMD issued a second statement in response to reports of “blowing up” of Ryzen 7000 processors. Motherboard makers can immediately begin a bios update that limits the maximum soc voltage, even for CPUs without 3D cache.

The processor manufacturer shared the statement Thursday with several tech sites that have previously reported on the matter, including Tweakers. After AMD announced yesterday that it was thoroughly investigating the reports, it now says it has found the root cause. To prevent more cases, AMD releases a new agea, which is the core bios component.

The new agesa version does not have a clear version number yet, but in any case it is newer than agesa which was released last week. Agesa has restrictions on “certain power rails on AM5 motherboards to prevent the CPU from going out of spec, including limiting Vsoc voltage to 1.3V.” AMD adds that the changes have no impact on the ability to overclock the memory, using EXPO or XMP, or using the Precision Boost Overdrive. The aforementioned Vsoc rail feeds the integrated GPU and memory controller in the Ryzen 7000 processors, among others.

Curiously, the processor designer mentioned “Ryzen 7000 series” in its statement, without specifically mentioning variants with 3D V-Cache. Most of the reports from users have been about the Ryzen 7000X3D versions, which have only been on the market for a relatively short time. The manufacturing technique of adding incremental spool is known for its sensitivity to high voltages. However, AMD suggests in its statement that all regular models are also vulnerable – thus the 3D V-Cache may be causing a problem latent in all Ryzen 7000 chips that came out earlier.

A bios update will appear for all motherboards with AM5 socket. According to AMD, that will happen in the “next few days,” but at the time of writing that looks like anyway ASUS It has already started uploading new bios versions for its motherboards. AMD recommends that users install the update as soon as it becomes available for their specific model.

Finally, the manufacturer urges consumers who have a processor affected by this issue to get in touch customers service. It understands and treats requests related to this topic with priority, according to AMD.
