ℹ️
Slot and capacity note
Source slot information: 1x 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.
ℹ️
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.
ℹ️
Everyday use and integrated graphics
Assess memory needs using your applications and current memory usage. Check device documentation for dual-channel support and recommended population; suitability of 2×8 GB or another configuration depends on model capacity and slot support.
