FAQs

Q: What is the difference between 5218 and 5218B?
A: 5218B is a vendor-specific variant with the same core count, base clock, and cache footprint; use identical CPUs within a server for proper operation.

Q: Can I mix 5218 and 5218B in the same UCS system?
A: Mixing is not recommended. Dual-socket systems should use matching model and stepping.

Q: Is this compatible with my UCS M5?
A: Yes, if your UCS M5 platform supports LGA3647 Xeon Scalable Gen 2. Verify with the Cisco HCL and current BIOS/firmware.

Q: What memory speed is supported?
A: Up to DDR4-2666 MT/s, dependent on DIMM type and population.

Q: Are AVX-512 and virtualization supported?
A: Yes, AVX-512, Intel VT-x, and VT-d are supported.
