HP EliteBook SODIMM upgrade

This 16 GB DDR4 3200 CL22 SODIMM targets owners of HP EliteBook 630 G9, 640 G9, 640 G10, 645 G10 and 650 G10 laptops who need more memory for everyday workloads. The 260-pin unbuffered module runs at 1.2 V and meets JEDEC PC4-25600 specifications. It is built for simple DIY installation in compatible business notebooks.

Replacing factory 8 GB or slower DDR4

Swapping a single 8 GB stick or slower DDR4 memory for this 16 GB PC4-25600 module adds capacity and bandwidth for multitasking and larger datasets. The jump is worthwhile when the system currently runs below 3200 MHz or has only one rank populated. Users already at 3200 MHz with matched pairs will see less benefit.

Check slot count and maximum supported memory

Verify the laptop has a free SODIMM slot or supports replacing the existing module before ordering. Confirm the platform accepts 16 GB non-ECC DDR4 at 3200 MHz and 2Rx8 organisation. The module has no heat spreader, so ensure chassis clearance is adequate. Matched capacity and speed across all slots is recommended for best stability.

Questions about this item

Will the 260-pin SODIMM fit the memory slot in my HP EliteBook 640 G9?

Yes, the module uses the standard 260-pin DDR4 SODIMM form factor required by the EliteBook 630 G9, 640 G9, 640 G10, 645 G10 and 650 G10.

What is the correct way to seat the module so the laptop recognises the full 16GB?

Insert the SODIMM at roughly a 30-degree angle until the gold contacts disappear, then press down firmly until both side clips click into the notches on the PCB.

Does this CL22 1.2V module require any firmware update or matching stick later on?

No firmware update is needed; it runs at JEDEC 3200 CL22 1.2V. For best stability, OWC recommends adding a second stick of the same capacity, speed and manufacturer.
