FAQs

Q: What does the “P” designation mean?
A: The 9554P is designed for single-socket (1P) servers only and cannot be used in dual-socket configurations.

Q: Is it compatible with UCS X‑Series?
A: Yes, in AMD-based UCS X‑Series compute nodes that support single-socket EPYC 9004 CPUs. Check the node’s HCL and required firmware.

Q: Can I upgrade from a non-P CPU to 9554P?
A: Only if your node is configured and supported for single-socket operation; verify heatsink/carrier and thermal requirements.

Q: What memory is supported?
A: DDR5 RDIMM/3DS RDIMM; speed is dependent on DIMM choice and population rules.
