B350 TOMAHAWK ARCTIC BIOS : 7A34vHKM (7A34vHKQ now)<--------------
This BIOS fixes the following problem of the previous version:
- Update AMD ComboPI1.0.0.3a
- Support Ryzen 3000 series CPU.
Ryzen 9 3900X/Ryzen 7 3800X/Ryzen 7 3700X/
Ryzen 5 3600X/Ryzen 5 3600/Ryzen 5 3400G/Ryzen 3 3200G
- Change BIOS UI to click BIOS(GSE-Lite) mode.
As you can see for your motherboard to support the Ryzen 3600 you have to install the latest BIOS which is the 7A34vHKQ. It's HKQ because this is a beta BIOS and the M is now a Q but you need this BIOS.
The version you updated to is a version from the date 2019 january. The Ryzen 3600 wasn't out at that date and only a BIOS version at a later date would work. So the latest one. (7A34vHKQ)
