FAQs

Q: Will this CPU work in my UCS X‑Series compute node?
A: Yes, if the node is LGA4677-based and on a supported firmware level. Check the UCS HCL and release notes.

Q: Is the heat sink included?
A: Varies by kit. Confirm the bill of materials for your UCS SKU; some options are CPU-only.

Q: What memory should I use?
A: Use approved DDR5 RDIMM modules (up to 4800 MT/s). Consult the server’s memory qualification list for best results.

Q: Can I mix this with a different Xeon model in a dual-socket system?
A: Mixing is not recommended; use identical CPUs for dual-socket configurations unless the platform explicitly supports otherwise.
