Question SuperMicro X11DPI-NT-O No video

[WizardTrading]

Built a new server and used an Intel Xeon Gold 6132 to upgrade the bios. everything worked perfectly fine with that Xeon CPU. installed an Intel Xeon 8259 cascade lake CPU and now no video, no post. just green lights on the motherboard. The supermicro board i have is the X11DPI-NT-O. i plan to go back to test the other cpu this afternoon.

Does anyone know what might be happening. The PSU (Corsair RM1000w) is new and worked fine previously with the other CPU. The memory (128GB) is all the same Crucial RDIMM which are supported by the motherboard.


Thanks for any suggestions and help

Does the BIOS specifically support the new CPU? Is CPU new or second hand.

I know my HP servers are fussy about non-OEM hardware changes, but you've got a SuperMicro board so you should be OK.

The BIOS is suppose to support these CPUs . The Motherboard supports Gen2 Xeon Processors according to the manual

The CPUs are used.

Thanks for the reply

What I would be concerned about is the 8259CL is NOT listed on the Intel ARK website. I am betting that CPU was only sold to OEMs. The Wikipedia page -- https://en.wikipedia.org/wiki/List_...de_Lake-based)#Xeon_Platinum_(octa_processor) shows this as a 210W CPU. The motherboard only supports 205W CPUs. I think you need to try to return that CPU and get a supported CPU.

i suspect you are correct and i appreciate your reply.

i found this other forum talking about similar issues with this chip and workarounds.

Xeon 8259CL

Has anyone purchased this CPU and got it working? I have tried on an HP and a Quanta server with no luck. Trying to see if the CPU is just bad. I know this is a custom AWS CPU. I actually deployed an AWS instance that uses this CPU and have verified the CPUID is the same as the other Second Gen...

was able to return the CPUs looking for something else for LGS3647
