Technical Specifications

FAQs

Q: Is this CPU compatible with my server?
A: It fits platforms supporting 2nd Gen Intel Xeon Scalable (Cascade Lake) on socket LGA3647. Verify your server’s CPU support list and BIOS/firmware level.

Q: Can I mix this processor with different models in a dual-socket system?
A: Mixing is not recommended. Use matching model, stepping, and microcode for stability and performance.

Q: What memory speed is supported?
A: Up to DDR4-2933; actual speed depends on DIMM type, capacity, and population rules.

Q: Does it support Intel Optane DC Persistent Memory?
A: Yes. It supports Optane DC PMem; overall per-socket capacity depends on the specific CPU suffix (L variants enable higher capacities).

Q: How many PCIe lanes are available?
A: 48 lanes of PCIe 3.0 per CPU.
