AGESA upgrades have played a key role in AMD’s strategy since the launch of the first generation of Ryzen. I vividly remember that because of these upgrades Sunnyvale could improve RAM support and stability with Ryzen 1000 and that in later generations they also had a significant impact in terms of compatibility, support, stability and even performance.

However, these updates also pose a significant risk because ultimately are implemented at the BIOS level and if they are not perfectly polished they can end up causing very serious problemssomething that just happened with the AGESA 1.0.0.4 update for Ryzen 7000 processors, which is causing some significant headaches for some AMD Ryzen 5 7600X users.

The information we have indicates that this update is causing problems for Ryzen 5 7600X CPU owners. in the version with two active CCD units, i.e. in those models that do not have their 6 cores in one CCD unit, but have them distributed in two units. What will happen is that the update will disable core 0, causing a significant loss of performance and in some cases the system will not even boot at all.

So far no issues have been detected on other processors, but it’s important to note the update was downloaded quickly from the websites of the major motherboard companies, so it’s clear that this ended up greatly reducing the scope of this problem, as after all the BIOS isn’t something we tend to update very often.

If you installed this update and basically didn’t notice anything weird, you shouldn’t worry. In case you are having problems, the only solution is to pass at this point go back to AGESA 1.0.0.3 update, i.e. to the version immediately below. If you downloaded the update and planned to install it during these days, it is better to do so even if you have a Ryzen 7 7700X or higher, because there is no guarantee that you will not have problems.
