FAQs

Q: Who should choose the 8280L over 8280/8280M?
A: Choose 8280L if your workloads require up to 4.5 TB of memory per socket, such as large in-memory databases and real-time analytics.

Q: Does this CPU support Optane DC Persistent Memory?
A: Yes, with supported server platforms and proper DIMM population rules.

Q: Is a heatsink included?
A: No. Purchase the correct server heatsink and airflow components separately.

Q: Can different CPU models be mixed in the same server?
A: No. Use identical CPU models and steppings across all sockets.

Q: What are the platform prerequisites?
A: Confirm LGA3647 socket, BIOS/firmware support for L-suffix memory capacities, and adequate power/thermal headroom.
