4 GB DDR3L SODIMM for EliteBook upgrades

This 4 GB DDR3L module runs at 1600 MHz with CL11 timing and 1.35 V operation. It uses a 204-pin SO-DIMM form factor and is unbuffered, non-ECC memory built with a 1Rx8 rank configuration. The stick is designed as a direct upgrade for specific HP EliteBook models.

Fits EliteBook 755 G3 820 G2 840 G2 only

This memory suits owners of the listed EliteBook models who need a single 4 GB module to fill one of the two available sockets. It will not work for buyers who require ECC error correction, registered buffering, higher capacities per module, or a different pin count or voltage.

1.35 V DDR3L voltage decides fit

The module operates at 1.35 V DDR3L specification, so it only belongs in systems that support this exact voltage. If the target laptop requires 1.5 V standard DDR3 or a newer DDR generation, this stick is not compatible.

Questions about this item

Will this 1.35 V DDR3L 1600 SODIMM run reliably in an EliteBook 840 G2 that currently uses 1.5 V DDR3 modules?

Yes, DDR3L is backward-compatible with 1.5 V slots; the module will operate at 1.35 V and the system will negotiate the correct voltage automatically.

How can I confirm the stick is running at CL11 1600 MHz after installation?

Open Task Manager or CPU-Z in Windows; the memory tab will show 1600 MT/s and 11-11-11 timings if the module is detected at its rated speed.

Does the package include only the single 4 GB SODIMM or are tools and a second stick provided?

The box contains one 4 GB 204-pin SODIMM; no screwdriver, no second module, and no adapter are included.
