Troubleshooting: Motherboard BIOS support requirements
The Socket AM4 and sTR4 platforms are designed to be a fully featured, scalable solution with
support for multiple processors, with varying capabilities. Since the release of 2000-series AMD
Ryzen™ and Athlon™ desktop processors, however there have been several BIOS updates made
available through our motherboard partners. These updates not only provide improved system
performance but also expand support for newer processors as they become available.
One of the possible reasons for a boot up issue is running an early BIOS that does not have support
for newer processors. This can be resolved by updating the motherboard BIOS to the latest version,
which can be performed by temporarily using a processor supported with the currently installed
BIOS, and swapping out the new processor after the BIOS has been updated. For a list of
supported processors per BIOS version, please refer to the CPU Support List document available on
your motherboard manufacturer's website:
 ASRock: https://www.asrock.com/support/cpu.asp
 ASUS: https://www.asus.com/support/cpu_support
 Biostar: http://www.biostar.com.tw/app/en/support/cpu_support.php
 Gigabyte: https://www.gigabyte.com/us/Support/CPU-Support
 MSI: https://www.msi.com/support/motherboard/cpu-support
On your motherboard manufacturer's website, make the appropriate selections to view the BIOS
version required to support your CPU. BIOS download and installation instructions are also found
on their website.
Workarounds
The following workarounds may be feasible for affected users, depending on their individual
circumstances, and should be considered before applying the boot kit solution detailed below:
Update from Retailer
1. If the motherboard was purchased through a computer parts retailer, check with the retailer to
see if they can facilitate the BIOS update at their location. There may be a charge for this, or it
may be offered at no cost.
2. If you have access to a processor supported on the current installed BIOS, use it to perform the
BIOS update, then swap out the processors when the update process is complete.
For a list of supported processors per BIOS version, please refer to the CPU Support List document
available on the motherboard manufacturer's website. BIOS download and installation instructions
are also found on their website.
