AMD AGESA 1007 turned out to be buggy support

AMD AGESA turned out to be buggy – support for 24GB and 48GB memory modules for Ryzen 7000 has been delayed

The AMD AGESA BIOS library for AMD 600 series motherboards for Ryzen 7000 processors currently contains many RAM compatibility bugs. Its release has been delayed for some time.

Shortly after a spate of complaints about Ryzen 7000X3D processors burning from high operating voltage, AMD and partners offered a quick but temporary fix by limiting the SoC processor’s operating voltage to a safe 1.3V in the motherboard BIOS. AMD promised to release a new library AGESA in early May, based on which motherboard manufacturers can create BIOS firmware for their products. These firmwares will first lower processor operating voltage limits to safe levels and introduce additional safety measures related to thermal limitations to eliminate any risk of processor burnout due to high voltage.

While most AMD partners have implemented some of these updates in BIOS firmware based on the AGESA library, ASUS decided to release a beta BIOS based on the new AGESA library. Apparently, as the practice of its use has shown, the mass release of the BIOS to AGESA will have to wait for some time. AGESA contains numerous deficiencies and bugs, especially related to overclocking capabilities of RAM modules and RAM compatibility with the platform.

AMD has already recognized these issues and is working with partners to address them in a new AGESA library internally named Version (AMD’s internal name). However, no one can guarantee that all of these errors will be corrected. AMD has recommended that all partners who have already released BIOS firmware based on the AGESA library roll these updates back to the previous version. This means that owners of AMD 600 series boards will have to resort to the BIOS of the AGESA library for some time, which contains operating voltage limits for Ryzen 7000X3D processors, but does not include the planned new temperature limits intended for the AGESA library will be introduced.

According to the informant chi11eddog, the current version of AGESA BIOS only supports 24GB and 48GB memory modules up to DDR5-4400. At least at this speed, a 192GB memory kit has been launched, although the manufacturer claims a higher speed for it. The BIOS firmware on AGESA, in turn, showed the ability to work with DDR5-6000 and even DDR5-6400 memory. In other words, in the new version of AGESA, AMD EXPO RAM overclocking profiles do not work properly and do not allow using faster RAM. Whether this issue will be resolved with the official release of the new AGESA is unknown.

According to the same source, the new settings for the PROCHOT Control and PROCHOT Deassertion Ramp features are also not available in the new AGESA. You are responsible only for the limitations associated with the temperature regimes of the processors. When the chip temperature reaches a critical level, the CPU and other system components will send out a PROCHOT signal. After that, the power consumption of the processor is reduced to avoid possible damage to the crystal. The PROCHOT deassertion ramp time in turn is responsible for the time intervals after which the processor returns to normal performance after the occurrence of the PROCHOT overheating signal.

It is not yet clear whether the new library AGESA (internal name) will be released as a new version of AGESA or as patch Motherboard manufacturers will receive the new AGESA library next week. New BIOS versions based on it will therefore appear at the earliest in the middle or even at the end of the current month.
