FAQs

Q: What does the P-suffix indicate?
A: P-series CPUs are optimized for single-socket (1P) servers and are not supported in dual-socket configurations.

Q: Is this CPU suitable for virtualization hosts?
A: Yes. The 64-core/128-thread design and large L3 cache make it ideal for dense VM and container workloads.

Q: Do I need a specific heatsink for this model?
A: Use a platform-qualified cooling solution rated for 360W TDP and follow server vendor installation guidelines.

Q: Will memory always run at 4800 MT/s?
A: 4800 MT/s is the maximum supported; actual speeds depend on DIMM type and population rules for the server.
