Hello, 

 

today I Ryzen 7 9800x3d and installed it. Before I installed latest bios. Unfortunately I got black screen on startup. When I switched back to original cpu got message that checksum is invalid and bios will automatically reset. It’s still working on old cpu. Need some help what I am doing wrong

@merbb,

 

Welcome to our HP Community forum!

 

You are doing nothing wrong, my friend!

 

However, your OMEN by HP 40L Gaming Desktop GT21-1xxx as fitted with the FrostBreath motherboard (SSID: 8A98) is not compatible -or at least, not yet, with a Ryzen 7 9800x3d.

 

The only other processors I could find online based on fellow GT21-1xxx Users which were not referenced in HP's FrostBreath motherboard specs, are the Ryzen 5 7600X and the Ryzen 7 7700X.

 

Unless and until HP releases new microcode/BIOS update, the best processor to date compatible with your rig would be the Ryzen 9 7900.

 

Meaning, the Ryzen 7 9800x3d is not compatible with your PC -at least not right now.

 

Kind Regards,
