Slot and capacity note
Source slot information: 2x SO-DIMM. This does not establish free slots. Dividing the total capacity limit by the number of slots does not establish a per-module limit; soldered memory and per-slot support need separate verification.
BIOS and manufacturer support
Before purchase, check the exact model’s service documentation and BIOS release notes. Treat a BIOS update as expanding memory support only when explicitly documented by the manufacturer.
