AMD AM5 motherboard enables fast DDR5 support
From 6000 MT/s sweet spot to enabling high-speed DDR5 memory with the latest BIOS.
AMD AM5 platform development has come a long way, and it appears that the latest AGESA 1.0.0.7 update, which is now available for some motherboards, and it is scheduled to be released later this month for others, shows significant improvement for DDR5 memory support.

The new AGESA is said to improve new memory synchronization mode which shows better compatibility and stability with high-speed memory modules. The new update which is already deployed for ASRock, shows that even on a relatively cheap sub-$300 motherboard gamers can see DDR5-8000 memory working, although it may need tinkering with the settings to get it full stable. The board used for this showcase by Buildzoid, is a B650 LiveMixer currently retailing at $223.

There are many other examples from the community members, overclockers and even motherboard makers themselves.

MSI MEG X670 ACE with Ryzen 9 7950X and DDR5-7600@8200 memory
The MSI X670E ACE motherboard, paired with a Ryzen 9 7950X processor and DDR5-8200 memory, boasts an impressive speed due to the latest AGESA update. This combination represents the fastest memory kit reported to be compatible with the new update. Notably, the testing took place on a high-end MEG ACE motherboard, which likely accounts for the exceptionally high memory speed support. The test was conducted using OLOY DDR5-7600 memory, which wasn’t originally validated for this speed but still delivered outstanding results.

The new BIOS is said to maintain the 1.3 SOC voltage, but it is possible to run high-speed memory even at 1.2V. This is still within the limits advised by AMD. According to the post on AMD Subreddit, the company has been working on the AGESA 1007B update for 2 months now. It is confirmed that many Ryzen 7000 systems will now be able to run 6400 MT/s memory with a 1:1 IC ratio.
This new firmware enables new settings that allow manual control that was previously hidden, including access to internal memory controller timing parameters. Memory kits using 7600-7800 MT/s should be now possible to run on many motherboards, and as shown by others, with proper hardware it may even reach higher.
