8GB DDR4 2400 SODIMM for HP EliteBook

This 8GB DDR4 2400 SODIMM module is built for HP EliteBook 840r G4, 850 G3, 850 G4, 850 G5, 850 G6 and x360 830 G6 notebooks. It delivers 2400 MHz speed with CL17 latency at 1.20V. The unbuffered non-ECC design uses a 260-pin layout and major-brand chips. It suits professionals upgrading compatible business laptops.

Check your EliteBook model and slot count

Verify the exact model number matches the supported list before ordering. The system accepts up to 32GB across two SODIMM sockets. A 64-bit operating system is required to address more than 4GB. All installed memory will run at the speed of the slowest module or the processor limit.

Suits single-stick upgrades on listed models

Ideal for owners of the named EliteBook and x360 models adding one 8GB stick. Not for systems outside the compatibility list, for ECC or registered memory requirements, or for builds needing matched-pair kits for dual-channel optimisation. Buyers wanting higher total capacity should confirm both sockets are free.

Questions about this item

Does the CM1024642400SO package contain only the 8GB SODIMM or any extra parts?

The box contains one 8GB DDR4 2400 SODIMM module and nothing else; no tools or cables are included.

My EliteBook 850 G5 has two slots and supports 32GB maximum — should I buy one 8GB stick or two?

For best performance install a matched pair so the memory runs in dual-channel mode; a single 8GB stick works but leaves the second channel unused.

Will the CL17 2400 MHz rating actually run at 2400 MHz inside my EliteBook 840r G4?

The module is rated DDR4 2400 CL17; the EliteBook 840r G4 memory controller sets the final speed, so it will operate at the highest speed the platform allows.
