Latest AGESA 188.8.131.52B microcode enables DDR5-8000+ support for AMD's AM5 motherboards
The AGESA 184.108.40.206B is now available from select motherboard makers with quite a few improvements for faster DDR5 memory kits. As reported by an AMD representative on Reddit, the new AGESA microcode is finally rolling out now after more than 2 months of development.
For now, only select B650 models from ASRock, X670 models from Asus and MSI as well as X670E models from Gigabyte and ASRock have received the update, but the new version should be released for all the other AM5 models towards the end of this month.
Some of the highlights for the 220.127.116.11B version:
- Memory Context Restore option can now reduce power-button-to-desktop times to around 15 seconds
- Many CPUs can run at least DDR5-6400 1:1 now
- DDR5-7200 CL32 is easier to achieve, and, depending on silicon lottery, DDR5-7600/7800 and even 8000/8200 speeds can be achieved with a bit of tinkering. Buildzoid showed that an ASRock LiveMixer B650 retailing for US$223 can run DDR5-8000 stably. MSI MEG X670 ACE can run DDR5-7600 OCed to 8200.
- DDR5 Nitro mode added to allow DDR5-7000 and above compatibility
- Added settings to let users change behavior of memory training. RAM kits can now be trained for a longer time and get better OC margins and stability.
