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.
It is not an HP branded product. It is a SUPERMICRO MBD-X9DR3-LN4F+-O Enhanced Extended ATX Server Motherboard Dual LGA 2011 DDR3 1600/1333/1066/800
and it is on the latest BIOS: R 3.0b
I only used the HP information as it was directly related to the issue I was having.
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.
