MSI Releases AGESA For Its Entire AMD 500-Series Motherboard Lineup

MSI has announced that its entire AMD 500 motherboard series have received the AGESA BETA BIOS. This beta BIOS update will give Smart Access Memory (Resizable BAR) support to older Zen2 processors (Ryzen 3000 series) and will provide small fixes to SMART reporting and the AIDA64 memory bandwidth test.

MSI has even sent a screenshot to Wccftech that shows the use of SAM on the Ryzen 9 3900XT CPU. Previously, AMD wasn’t willing to confirm whether Zen 2 processors will support Resizable BAR or not, but they had to speed things up after Intel announced that their 10th Gen Core will support Resizable BAR technology.

It remains to be seen if NVIDIA’s RTX 3060 or other upcoming cards with ReBAR support will be compatible with this technology or not as MSI has only tested AMD Radeon RX 6800. NVIDIA has confirmed that its graphic cards will be compatible with Intel 10th & 11th Gen processors and AMD Ryzen 5000 series. NVIDIA confirmed this before AMD’s official announcement about SAM support for its Zen2 CPUs; hence there are high chances that the RTX 3060 will benefit from ReBAR when plugged in a MSI 500 series motherboard and paired with Ryzen 3000 series processors.

AIDA64 L3 Cache issue fix:

This system information and diagnostic software showed users a reduced bandwidth for Ryzen 5000 series, which made the users believe that their processor is underperforming. AMD has announced that this issue has been taken care of in the latest version of AGESA. Moreover, the Director of Technical Marketing at AMD, Robert Hallock, made a post on Reddit which confirmed that the software will not affect performance in any other software.

When MSI provided the screenshot to Wccftech, they also claimed that the L3 cache fix has improved the gaming performance, but Hallock’s Reddit posts prove it as incorrect and deceptive. There is a possibility that MSI might have mislabelled the chart, and is most probably showing the Smart Access Memory performance gain.
