FAQs

Q: Is this CPU compatible with Cisco UCS X-Series compute nodes?
A: Yes. It is intended for UCS X-Series M7-generation nodes that support 4th Gen Intel Xeon Scalable LGA4677 processors. Always confirm with your server’s CPU support matrix and required BIOS/firmware.

Q: Does this include a heatsink or carrier?
A: Typically no. CPUs are supplied as processor-only; heatsinks, carriers, and installation hardware are server-specific options sold separately.

Q: What memory is supported?
A: DDR5 RDIMMs up to 4800 MT/s (speed depends on DIMM type, rank, and population). ECC is supported.

Q: What is the difference between 6438N and 6438Y+ parts?
A: Both are 32-core 2.0 GHz processors with 60 MB cache on the same platform; the suffix reflects OEM/platform option codes. Use the code qualified for your specific server bill of materials.

Q: Can this be used in dual-socket configurations?
A: Yes, multi-socket support is provided. Follow your server’s CPU population and matching rules.
