System-Specific DDR4 SODIMM for EliteBook

This 4 GB DDR4 module is built for HP EliteBook 840 G6 and 850 G4 through G6 laptops. It delivers 2400 MHz speed with CL17 latency at 1.2 V in a 260-pin unbuffered SODIMM form factor. The non-ECC, single-rank design meets JEDEC standards for a warranty-safe upgrade.

Replaces factory-fitted memory when capacity

Upgrading from the original 4 GB or 8 GB sticks lets the system keep more applications and browser tabs in active memory. The jump is worthwhile when the current configuration forces frequent paging to storage, slowing everyday workloads. Matching speed and voltage avoids down-clocking or instability.

Fits the SODIMM slot inside compatible EliteBook

Installation requires only a small screwdriver and access to the memory compartment on the underside of the laptop. The module uses the existing 1.2 V power rail and needs no BIOS adjustment beyond automatic detection. It frees no additional slots, so total capacity depends on how many sockets the specific model provides.

Questions about this item

Does the 260-pin SODIMM fit the memory slot on my HP EliteBook 840 G6?

Yes, the module uses the standard 260-pin DDR4 SODIMM form factor that matches the slot in the EliteBook 840 G6 and the listed 850 G4, G5 and G6 models.

What is the correct way to seat the module, and what step do people often miss?

Align the notch with the slot key, insert at a slight angle, then press down firmly until both side clips click into the notches — the click is the step many forget.

Will this 4 GB stick need any firmware updates or replacement batteries over time?

No, DDR4 SODIMMs have no firmware or batteries; the module is a passive component that lasts the life of the laptop unless physically damaged.
