HP EliteBook 840 14 inch G10 Notebook PC upgrades
HP's datasheet footnote says memory slots are not customer accessible/upgradeable, though other sources show two standard SODIMM slots. Check HP's service guide and warranty terms before upgrading.
- SODIMM memory slot: 2 × DDR5 SO-DIMM · up to 64 GB total · 4800 MT/s
- M.2 2280 NVMe slot: SSD M.2 2280 (NVMe) · up to 2 TB
SODIMM memory slot 2 × DDR5 SO-DIMM · up to 64 GB total · 4800 MT/s
Non-ECC unbuffered DDR5 SO-DIMM. 64 GB total implies 2 x 32 GB, but no source states the per-module limit. HP datasheet lists DDR5-4800 max; shipping units use DDR5-5200. Two modules enable dual channel. HP recommends HP-branded memory.
