prodesk 400 g4 dm CPU upgrade

HP Recommended
prodesk 400 g4 dm
Microsoft Windows 10 (64-bit)

Hello, just picked up a prodesk with an 8th gen Pentium and a B360 chipset. I know this chipset supports 9th gen CPUs, but may need a bios update. Will a 9th gen chip work in this prodesk that shipped with an 8th gen CPU?

Below is the link to the HP quickspecs for the  prodesk 400 g4 dm.


The supported processors can be found on pages 13 -17.


Make sure you look under the DM grid.


No 9th gen core processors are supported.


I don't see any BIOS updates that added support for new processors.


You can read the release notes for each update at the link below.
