8GB DDR4 SODIMM for HP ProBook 640 G2

This 8GB DDR4 2133MHz module upgrades the HP ProBook 640 G2. It is a 260-pin SO-DIMM running at 1.2V with CL15 timings. The unbuffered, non-ECC stick uses a 2Rx8 rank configuration. It targets owners of that specific laptop seeking a memory increase.

DDR4 2133MHz speed and two-slot maximum

The laptop accepts DDR4 2133 (PC4 17000) memory across two sockets. Total system memory cannot exceed 16GB, so a single 8GB module leaves one slot free for a matching stick. Faster DDR4 modules will downclock to 2133MHz. The platform does not support ECC or registered DIMMs.

Check your current slots and model number

Verify the exact ProBook 640 G2 part number such as V1H09UT, V1P72UT or W0S35UT before ordering. Confirm how many of the two SODIMM slots are already populated. The module height is standard SO-DIMM profile without a heat spreader.

Questions about this item

Is the single 8GB stick or a two-stick kit better for my HP ProBook 640 G2?

The ProBook 640 G2 has two SODIMM slots and supports up to 16GB total. This single 8GB module leaves the second slot free for a matching stick later, giving you the full 16GB when you add it.

What does the 2133MHz rating actually deliver inside the laptop?

The module runs at DDR4-2133 with CL15 timings at 1.2V. In the ProBook 640 G2 the memory controller will operate it at this rated speed, providing the standard bandwidth and latency for this platform.

Will the 260-pin DDR4 SO-DIMM fit and work in my ProBook 640 G2?

Yes. The ProBook 640 G2 uses DDR4 SO-DIMM slots, and this 260-pin unbuffered non-ECC module matches the required form factor, voltage and pin-out exactly.
