FAQs

Q: Which socket and platform does this CPU require?
A: It is designed for SP5 (LGA 6096) platforms and Cisco UCS servers that support AMD EPYC 9004-series processors.

Q: Does this include a heatsink?
A: Heatsink and carrier are server/BOM dependent. Use an SP5-compatible thermal solution specified by your Cisco UCS chassis/blade or rack server.

Q: What memory is supported?
A: 12-channel DDR5 ECC with speeds up to 6000 MT/s; achieved speeds depend on DIMM type and population.

Q: Is this suitable for virtualization?
A: Yes. High core-count, large L3 cache, PCIe 5.0, and AMD security features (e.g., SEV-SNP) make it well-suited for virtualization and cloud workloads.
