FAQs

Q: Is this compatible with my HPE server model?
A: Check the server’s QuickSpecs; the platform must support AMD EPYC 9004 (SP5) processors and the specific option kit.

Q: Can I mix this with a different EPYC CPU in a 2P server?
A: No. Dual-socket configurations require identical processors (model, stepping, and TDP).

Q: What memory configuration is recommended?
A: Use supported DDR5 ECC RDIMMs and populate all 12 channels per socket symmetrically for best performance.

Q: Is a heatsink included with the CPU option?
A: Use the server’s approved heatsink/thermal kit as specified for your chassis and airflow direction.

Q: Does it support virtualization and memory encryption?
A: Yes. AMD-V and AMD Infinity Guard features (e.g., SEV/SEV-ES/SEV-SNP) are supported when enabled by firmware and OS.
