8GB DDR4 2400 SODIMM for EliteBook

This 8GB DDR4 2400 SODIMM module upgrades HP EliteBook 820 G4, 830 G6, 840 G4, 840 G5 and 840 G6 notebooks. It runs at 1.20V with CL17 timing and uses a 260-pin unbuffered non-ECC design. The single stick installs directly into an available memory slot.

Who this suits and who should look elsewhere

It suits owners of the listed EliteBook models who need a straightforward 8GB capacity increase. Buyers whose laptop is not in the compatibility list or who require ECC registered memory should look elsewhere. Systems limited to lower DDR4 speeds will run this module at the slower rate.

Deciding spec: 260-pin DDR4 2400 SODIMM

The 260-pin DDR4 2400 SODIMM form factor decides fit. Only notebooks accepting this exact pin count, voltage and generation will accept the module. Match your service manual to these specifications before ordering.

Questions about this item

How can I confirm the CM1024642400SO is running at 2400 MHz and CL17 after installation?

Open Task Manager or a tool such as CPU-Z; the memory tab should show DDR4-2400 with timings 17-17-17 at 1.20 V.

What does the box contain and what must I source separately?

The package includes one 8 GB 260-pin DDR4 SODIMM stick; no screws, tools or additional modules are supplied.

Should I choose the single 8 GB stick or add a second for 32 GB maximum?

Each EliteBook listed supports two sockets up to 32 GB total; a second identical stick enables dual-channel operation.
