According to several Reddit, Twitter, and TechPowerUp reports, AMD has massively improved DDR5 memory support on the AM5 platform with a new microcode update known as AGESA 1.0.0.7b. The update allows some boards to push DDR5 frequencies as high as 8000MHz without issue and boosts the optimal 1:1 (UCLK:MEMCLK) ratio to 6400MHz. Gigabyte and ASRock have already published stability runs with the new BIOS update, showing off 8000MHz and 7200MHz working perfectly on the Aorus X670E Master and X670E Taichi.
Only a few AM5 motherboards have the new microcode update for now. Still, we suspect the update will become more readily available over the next couple of weeks, depending on the launch schedule of each motherboard manufacturer.
