Targeted 8GB DDR4 upgrade for select HP ProBooks

This 8GB DDR4 2133MHz CL15 SODIMM is built specifically for HP ProBook 430 G4, 470 G4, 640 G2, 650 G2 and 655 G3 notebooks. It delivers a JEDEC-standard PC4-17000 module that fits the 260-pin slot and runs at 1.2V without ECC or buffering.

Steady multitasking headroom under continuous load

The CL15 latency and 2Rx8 rank organisation keep data flowing during extended sessions with many browser tabs, documents or background services. Because the module follows strict JEDEC timings, the memory controller can sustain its rated throughput without throttling or timing violations.

Cool, quiet operation at standard laptop voltage

Operating at 1.2V, the unbuffered Non-ECC stick adds minimal heat to the system's existing thermal envelope. No heat spreader is fitted, so the module relies on the chassis airflow already present in the compatible ProBook designs, keeping fan behaviour unchanged.

Questions sur cet article

Does the OWC 2S1D42R808GB 8GB DDR4 2133MHz CL15 1.2V SODIMM run hot or draw extra power when the laptop is under load all day?

The module operates at the standard JEDEC 1.2V and has no heat spreader, so it adds minimal heat and power draw during sustained use.

What does the buyer need to already own for this 260-pin DDR4 SODIMM to work?

A compatible HP ProBook 430 G4, 470 G4, 640 G2, 650 G2 or 655 G3 with a free DDR4 SODIMM slot.

How does this CL15 2133MHz DDR4 module behave alongside the factory memory already in an older ProBook?

It will run at the system's lowest common speed and latency; the 2Rx8 rank is compatible with the listed ProBook platforms.
