ASUS BIOS based on AGESA provides new features

The AMD Ryzen 7000X3D series processors are coming soon, and motherboard manufacturers are preparing new BIOS versions for their B650 and X670 series motherboards. These firmware updates will be based on the new AGESA microcode to support the new processors with 3D Vertical Cache (3D V-Cache) technology. ASRock and MSI have already released new firmware updates, while ASUS has a beta version, but there is no news yet from Gigabyte.

At CES 2023, AMD unveiled three desktop processors based on the Zen 4 architecture, all featuring 3D V-Cache technology: the Ryzen 9 7950X3D, Ryzen 9 7900X3D, and Ryzen 7 7800X3D, all with a TDP of 120W and an additional 64MB of L3 cache capacity. This means that even in models with dual CCD, only one CCD will have increased SRAM.

This asymmetric configuration can be a problem for users, even though AMD promises to work with Microsoft to ensure that the Windows operating system can recognize the difference between the two CCDs and allocate tasks accordingly. However, the software is not always that “smart”. According to Hothardware, ASUS has a menu in the BIOS called “Core Flex”, designed for Ryzen processors with multiple CCDs and 3D V-Cache, as it allows you to configure when the processor will swap a task from one CCD to the other.

Since this is set in the BIOS, the operating system or driver may not be aware of it. This method not only applies to Windows but also for Linux. There seem to be multiple “algorithms” that can be configured, and users can choose from various conditions, including core current and memory usage, to help the processor recognize and schedule tasks.

Although ASUS’s feature gives users more choices, it would be ideal if the operating system could allocate tasks effectively and make efficient use of resources. Since AMD has stated that they are collaborating with Microsoft on this issue, it may be worth waiting a few more days to see the actual results.
