FAQs

Q: What workloads benefit most from this 64-core model?
A: Virtualization clusters, databases, analytics, microservices, and general-purpose enterprise apps that need a balance of core count and per-core performance.

Q: Is memory speed limited with full DIMM population?
A: Yes, maximum achievable speed can vary based on DIMM count and type. Refer to your server’s memory population rules.

Q: Can I use it in a single- or dual-socket configuration?
A: It supports both, provided your server model and firmware support the configuration.

Q: Are AVX-512 instructions supported?
A: Yes, including VNNI extensions for acceleration of AI inference and vector workloads.

Q: Do I need matched CPUs in dual-socket servers?
A: Yes, both CPUs must be identical model/stepping for supported operation.
