I need a list of Copatable CPU's

[Ross_InvestAcc]

Hi 

I need a list of compatible CPUs for the HP 8434 Version 11 Motherboard and I cannot find one anywhere 

I need to upgrade one of my works PC's to Windows 11 and the CPU is the only part not compatible 

The pc is an HP 285 G3 MT Business PC

Hi:

None of the supported processors in the HP 285 G3 MT Business PC meet Microsoft's W11 minimum processor specs for AMD processors.

Windows processor requirements Windows 11 supported AMD processors | Microsoft Learn

If you are interested in installing W11 on your PC as is, you can read this discussion for how I upgraded several HP and Dell notebook and desktop PC's that did not meet the W11 hardware requirements to W11 22H2.

If the in-place upgrade fails, you should be able to clean install W11 using the bootable W11 installation flash drive you made with Rufus.

Thank you, but that list isn't correct, It doesn't even show the processor that is in it now 

it currently has a Ryzen 3 2200G in it 

I have an app that checks for Windows 11 compatibly and the only thing that isn't compatible is the CPU

everything else on the machine is fine

I just need a list of compatible CPU's for this motherboard

You're very welcome, @Ross_InvestAcc 

Here's another specification sheet...there is one that meets the requirements.

HP 285 G3 Microtower PC

See page 5.

You can install the 2700 Pro and that will meet W11's requirement.
