8GB DDR3L SODIMM for EliteBook 755 G3 820 G2 840 G2

This 8GB DDR3L module runs at 1600 MHz with CL11 timing and 1.35V operation. It targets owners of HP EliteBook 755 G3, 820 G2 or 840 G2 notebooks who need a direct memory upgrade. The 204-pin SO-DIMM form factor matches the factory slot exactly. It is not for buyers who want more storage or a different memory generation.

Installation ease and common issues

The stick inserts into an accessible SO-DIMM slot after removing the bottom cover. No BIOS update is required because the module uses standard JEDEC timings of 11-11-11 at 1.35V. The only typical problem occurs if the notebook already has two populated slots, since these models support a maximum of 16GB across two sockets.

Sustained load behaviour

Unbuffered DDR3L runs at the rated 1600 MHz continuously without downclocking under thermal pressure. The 2Rx8 organisation keeps latency stable during long compile jobs or virtual-machine workloads. No heat spreader is fitted, so airflow in the chassis determines peak temperature.

Questions about this item

How can I verify the module is running at the rated 1600 MHz CL11 1.35 V after installation?

Open the BIOS or a system-information tool such as CPU-Z and confirm the memory tab shows DDR3L 1600 MT/s, CAS latency 11-11-11 and 1.35 V operation.

What ships in the package and is anything else required to install it?

The box contains one 8 GB 204-pin SODIMM stick; no extra cables, brackets or tools are needed — just a compatible laptop slot.

Should I choose the 8 GB stick or add a second one to reach the 16 GB maximum on my EliteBook 840 G2?

The EliteBook 840 G2 supports two sockets up to 16 GB total, so a single 8 GB module works alone or you can install a matching second stick for the full 16 GB.
