Thanks for joining the Processor community.
At this stage, I recommend updating computer BIOS, see link below for reference:
Test different processor on your system, if you are not getting same issues, this means you may have defective processor. Check with Contact HP Support and Customer Service | HP® Support for possible warranty replacement.
Thanks for the information.
For this type of server product, you need to contact Super Micro Computer, Inc. - Support Home, the issue you described is directly related to your motherboard manufacturer.
