Targeted HP EliteOne & EliteBook upgrade

This 8GB DDR4 SO-DIMM is built for HP EliteOne 830 G5, 840 G3, 840 G4 and 840 G5 systems. It delivers 2400 MHz speed with CL17 timing at 1.2V in a 260-pin unbuffered format. The module uses major-brand chips in a 2Rx8 configuration and ships as a single stick for simple capacity increases.

Suits owners of listed HP models needing more memory

Buyers whose laptop or all-in-one is not in the compatibility list should look elsewhere. Systems requiring ECC or registered modules cannot use this non-ECC unbuffered stick. Machines already at the 16GB maximum across two sockets will not benefit from adding another module.

Straightforward SO-DIMM installation

Power down, open the memory compartment, align the notch on the 260-pin edge connector and press firmly until the retention clips click. Common issues arise when the stick is not fully seated or when a second slot is already populated with an incompatible rank or speed.

Questions about this item

Does this 260-pin DDR4 SO-DIMM require a laptop with an open SO-DIMM slot?

Yes, it installs in a standard 260-pin DDR4 SO-DIMM slot. The compatible HP EliteOne and EliteBook systems listed have two such sockets and support up to 16 GB total.

Will the CL17 timing slow down my existing DDR4 2400 CL15 module?

The memory controller will run both sticks at the slower CL17 timings, so the CL15 module will operate at CL17 while paired with this 2Rx8 module.

How can I verify the module is running at DDR4 2400 after installation?

Check the memory speed in BIOS or with a tool like CPU-Z; it should report 2400 MT/s (PC4-19200) at 1.2 V with 17-17-17 timings.
