[Hardware] AMD AGESA 1.2.0.1 improves L3 cache bandwidth on Ryzen 5000 processors

The arrival of AMD Ryzen processors on the market has changed the way it is. Intel will soon make the leap to MCM processors with Alder Lake-S chips. But meanwhile AMD continues to work on improving the performance of its processors. This is why AMD releases the new AGESA 1.2.0.1 microcode for Ryzen 5000 processors.

 

For those who do not know what the AGESA microcodes are, it is the code on which the Ryzen BIOS are built. What this firmware allows is to improve the processor support for the different families of chipsets. They also offer other capabilities such as performance improvements, support for technologies such as Resizable BAR, among others.
 
This new AGESA 1.2.0.1 microcode implements SMART technology false error correction for M.2 NVMe SSDs that implement SK Hynix memory chips. Also fixes a bug that intermittently detected M.2 SSDs via SATA interface.

 

Some improvements have also been integrated. Improved stability of disabled cores on AMD Ryzen 5 5600X and Ryzen 7 5800X processors under AMD Ryzen Master software. It is not a fairly common practice, but it is interesting for overclocking.

 

Additionally, the bandwidth of the L3 cache has been improved, practically doubling the speed, with the consequent improvement in performance. This improvement has been under the AIDA64 benchmark, so it is not known if this improvement will work outside of said software.

 

Predictably within two weeks or more we should start seeing new BIOSes with AMD microcode. It will be a matter of waiting for MSI, ASUS, ASRock or Gigabyte to launch the new BIOS. Then you simply have to go to the website of the manufacturer of your motherboard and download and install the new BIOS.
