So this laptop clearly says on its cover: HP Elitebook 840 G3
I searched google for "HP Elitebook 840 G3 tech specs". Right?
HP EliteBook 840 G3 - Specifications | HP® Customer Support
and the page title is : HP EliteBook 840 G3 - Specifications
so we are on the right product, right ?
and this is what it says:
DDR3L PC3L-12800 (transfer rates up to 1600 MT/s)
Two SODIMM slots supporting dual-channel memory
Both slots are customer accessible/upgradeable
4096 MB total system memory (4096 MB x 1)
8192 MB total system memory (4096 MB x 2)
8192 MB total system memory (8192 MB x 1)
16384 MB total system memory (8192 MB x 2)
Went to Amazon, looked for the DDR3L PC3L-12800 and bought the Crucial 16GB Kit (8GBx2) DDR3L 1600 MT/s (PC3L-12800) SODIMM 204-Pin - CT2KIT102464BF160B
When those arrived, they are completely incompatible with my laptop.... they don't fit in the slot. WHY??
Attached is a pic of the present, the old, the 4GB ram that is installed by default and is working on the laptop....
