8GB DDR4 SO-DIMM for HP ProBook

This 8GB DDR4 2400 CL17 module is built for HP ProBook 455 G6, 455R G6, 470 G3 and x360 440 G1 laptops. It uses a 260-pin SO-DIMM form factor, runs at 1.2V and is unbuffered non-ECC. The single stick expands memory in compatible systems without requiring configuration changes.

Check slots and OS before ordering

Verify your laptop has a free SO-DIMM slot; the supported platforms offer two sockets with a 32GB maximum. A 64-bit operating system is needed to address more than 4GB of memory. All installed modules will run at the speed of the slowest stick or the processor limit.

Replaces slower or smaller DDR4 sticks

Swapping a 4GB module or a lower-frequency DDR4 SO-DIMM for this 8GB CL17 unit adds capacity and can raise the memory clock to 2400 MHz. The upgrade is worthwhile when the system currently runs at a lower speed or has only one populated slot.

Questions about this item

Does the package include anything besides the single 8 GB DDR4 SO-DIMM?

The box contains one 260-pin DDR4 2400 CL17 module rated at 1.2 V; no heat spreader, cables or tools are supplied.

My ProBook 455 G6 has two slots and supports up to 32 GB — should I add one stick or a matched pair?

Installing two identical 8 GB sticks in the two slots enables dual-channel operation and lets the system reach the full 32 GB limit; a single stick works but runs in single-channel mode.

Will the CL17 2400 MHz rating actually run at that speed in an HP ProBook x360 440 G1?

The module is rated DDR4-2400 CL17, but the laptop’s memory controller and any slower modules already installed will determine the final operating frequency and timings.
