@Tekapa,

Welcome to our HP Community forum!

An excellent question, and I researched this for you.

Looking at your PC platform (GT21-0xxx as fitted with the HanaOAC motherboard with SSID: 8949 -please verify) as well as closely related PCs in Userbenchmark, I could not find any users who managed to get the Ryzen 7 5800X3D to work.  Here is a comprehensive list of compatible processors for your PC:

Ryzen 5 5600G

Ryzen 5 5600X

Ryzen 7 5700G

Ryzen 7 5800X

Ryzen 7 5800XT

Ryzen 9 5900X

Ryzen 9 5950X

I noticed one related PC, an HP OMEN 25L GT12-1xxx with a Hana motherboard (SSID: 8876) fitted with the Ryzen 7 5800X3D: HP OMEN 25L Desktop GT12-1xxx Performance Results - UserBenchmark, but even though HP's motherboard naming is confusingly similar, these two motherboards use entirely different BIOS ecosystems.  Meaning, the HanaAOC motherboard despite having the exact same physical AM4 socket and B550 chipset as the Hana motherboard, HP's official CPU support list AND actual user data for the HanaAOC board tops out at standard 5000-series chips like the Ryzen 9 5900X or Ryzen 7 5800X. HP never officially updated the HanaAOC BIOS firmware to support the 3D V-Cache architecture of the 5800X3D.

If you were to drop a Ryzen 7 5800X3D into your HanaAOC motherboard, the PC will likely experience a Black Screen / No POST failure. The motherboard simply will not recognize the CPU instruction set.  Meaning, you could try it I suppose, but chances are it is not going to work.

Hope this was helpful.

Kind Regards,
