FAQs

Q: Is a cooler included with this CPU?
A: No. Order an appropriate heatsink and airflow kit approved for your server chassis.

Q: How does 8280 differ from 8280M/8280L?
A: Performance characteristics are similar; the suffix indicates supported memory capacity (1 TB for 8280, 2 TB for 8280M, 4.5 TB for 8280L per socket).

Q: Can this CPU be used with Optane DC Persistent Memory?
A: Yes, provided the server platform and BIOS support Optane DCPMM and correct population rules are followed.

Q: Can I use different CPU models together?
A: Use identical CPUs across sockets for supported multi-CPU configurations.

Q: What platform requirements should I check?
A: Confirm LGA3647 socket, BIOS/firmware support, VRM/TDP capability, and inclusion on the server’s CPU support list.
