FAQs

Q: What is the difference between 8276 and 8276L?
A: The 8276L is the high-memory variant supporting up to 4.5 TB per CPU (with DCPMM), ideal for very large in-memory datasets.

Q: What memory types are supported?
A: ECC RDIMM/LRDIMM DDR4-2933 and Intel Optane DC Persistent Memory modules, subject to platform support.

Q: Do I need special licensing to use the high-memory capability?
A: No additional CPU license is required; ensure your server platform and DIMM population rules support the capacity.

Q: Is a heatsink included?
A: No, as a tray CPU it requires a server-qualified cooling solution.

Q: Can I pair this with a non-L Xeon in a multi-socket system?
A: Use matched CPU models; mixing L and non-L variants is not recommended.
