AMD's latest AGESA BIOS degrades the performance of Ruilong R57600X, which can no longer be powered on in severe cases.

Thanks to CTOnews.com netizen OC_Formula, Xiao Zhan cut, South China Wu Yanzu clue delivery! CTOnews.com January 9 news, before reading this article, let's first review an article published by CTOnews.com last year,"AMD R5 7600X part adopts dual Zen 4 CCD design, but only 6 cores and 12 threads," this news once caused netizens to discuss the opening of the core.

At that time, some users found that AMD Ryzen R5 7600X desktop CPU has two designs, one with a single CCD design, while some models use two CCDs, which led to the existence of two R5 7600X phenomena on the market.

This is not a problem, but AMD and Intel usually issue firmware updates to address critical vulnerabilities such as Spectre, and usually to "improve system stability and optimize system fluency," but due to certain details, these microcode updates can cause problems, such as now.

Some users have found that after AMD released the latest AGESA 1.0.0.4 firmware update for the Ryzen 7000 series, Ryzen 5 7600X experienced severe performance degradation, and the most serious may not even be able to boot.

It is worth noting that not all R5 7600X were affected. Some developers pointed out that AMD appears to disable Core0 in the AGESA update, which affects some dual-CCD R5 7600X processors.

That said, SMU version 84.79.204 has a Bug, and the new SMU version 84.79.210 should fix it. At present, in addition to Gigabit motherboard manufacturers have also removed AGESA 1.0.0.4, users who have not updated can jump directly to the latest version, and if you have installed this update, it is recommended to roll back to the previous firmware version, and then download the latest version of the BIOS update from the official website.
