Technical Specifications

FAQs

Q: Is this compatible with my UCS server model?
A: It is compatible with UCS servers that support SP3-socket 7003-series class CPUs. Consult the official UCS CPU support matrix for confirmation.

Q: Does the lower L3 cache affect performance?
A: For many workloads, higher base frequency and core count offset smaller L3. Cache-sensitive workloads may see different scaling; evaluate against your profiles.

Q: Can it be used in dual-socket configurations?
A: Yes, provided your UCS platform and BIOS support it in 2P.

Q: Do I need specific memory modules?
A: Use server-grade ECC RDIMM or LRDIMM qualified for your UCS model; speeds up to DDR4-3200 are supported.
