At least some of Intel's Sapphire Rapids CPUs to feature onboard HBM memory.

0220H - HBM command / address parity error.
0221H - HBM data parity error.

That seems to be the only HBM info in the manual. It indicates that the memory controller has support for HBM. It would be a big jump to conclude this means there is HBM on-package.

Well, given the ball density of HBM modules and the requirement that traces between endpoints be too short for transmission line effects to be a major concern, any HBM has to be on-substrate with whatever chip hosts the memory controller by definition.

Does it indicate even that much? I mean, the CPU could encounter an HBM error when it accesses HBM memory on an accelerator over CXL.

Yes, that is likely the use. The Xe-HPC Ponte Vecchio GPUs will have stacks of HBM2e and the sketchy plans presented so far are for the Sapphire Rapids chips to access those GPUs via CXL .

Thank you for the update regarding the intel chip set.
Now I can update my hardware with this chip set so that my pc can run faster.
