AMD officially provided the motherboard makers with the microcode AGESA 126.96.36.199 – the one that implements a lot of improvements for the Ryzen 3000 series processors. At the same time, the company talked about the microcode features and some of the most interesting innovations.
What you need to know for potential users of the flagship 16-core Ryzen 9 3950X processor – it will only work with a motherboard whose BIOS is built on AGESA 188.8.131.52. Since the developers of the motherboards have already received the microcode, then you should not particularly worry about this. However, when assembling the system, it will be necessary to take this point into account and, if necessary, upgrade to the corresponding BIOS version.
In the BIOS based on AGESA 184.108.40.206, the so-called Eco Mode will appear. When activated, the TDP restriction is triggered. For example, for processors with a TDP of 95 and 105 W, it will decrease to 65 W, and for models with a TDP of 65 W – up to 45 W. Of course, performance will suffer, but energy efficiency will increase. In some cases, this may be useful.
From other innovations: the performance of the 12-core Ryzen 9 3900X is separately optimized, the compatibility and stability of the Ryzen 3000 CPU and X570-based motherboards are improved – this applies to both different modes (ACPI power state) and different subsystems – PCIe, USB, SATA . AGESA 220.127.116.11 also allowed to reduce the time spent on self-test after switching on (POST) and loading – depending on the system board, loading is accelerated by up to 30%.
