Frequently Asked Questions

What is the difference between Xeon Platinum 8558P and standard Xeon Platinum 8558?

The 8558P is a performance-optimized variant of the 8558 with higher base frequency or cache configuration. The P”” designation typically indicates a higher-performance bin within the same core count family. Consult Intel ARK and HPE QuickSpecs for detailed specification differences between variants.

Does P67108-B21 support dual-socket (2P) configurations in Gen12?

Yes — the Xeon Platinum 8558P uses 20GT/s UPI-3 for high-bandwidth inter-socket connectivity in dual-socket Gen12 deployments. Both sockets must be populated with identical processor models for validated 2P operation per HPE ProLiant Gen12 QuickSpecs.

What memory does P67108-B21 support?

The Xeon Platinum 8558P supports DDR5-6400 memory channels. In HPE ProLiant Gen12 it works with HPE DDR5-6400 RDIMMs for maximum memory bandwidth. Consult HPE ProLiant Gen12 QuickSpecs for validated memory population rules and maximum capacity.
