AMD announced EXPO Ultra Low Latency at Computex this month, promising to bring it to most AM5 motherboards as part of the EXPO 1.2 update. We've known about EXPO 1.2 since April, when it first showed up in BIOS releases, and it has already been available on 800-series motherboards for a while. Now, the first batch of 600-series motherboards have begun receiving ULL support as well.MSI and Asus have both just pushed out new AGESA 1.3.0.1b BIOSes to various X670 products. Asus has updated the X670E Hero, X670E Gene, X670 Extreme, X670E-A Gaming Wi-Fi, X670E-E Gaming Wi-Fi, X670E-F Gaming Wi-Fi, and X670 Creator Wi-Fi. The X670E-I Gaming Wi-Fi, X670E-Plus, and X670-E Plus Wi-Fi are missing their subsequent updates for now, but they should be coming soon.These are all beta releases, so keep in mind they're not intended for most users. We also checked a bunch of B650 support pages manually (since they don't have a dedicated thread like X670), and no Asus motherboard seems to have been updated to AGESA 1.3.0.1b yet. They're all running the AGESA 1.3.0.0 or 1.3.0.1 releases from months ago, but don't explicitly mention EXPO ULL support being added.

Some models like the MAG X670-E Tomahawk Wi-Fi actually added ULL support back on May 27th when they were updated to 1.3.0.1, but that news was missed by most of the community.
