OWC 2S1D42R808GB 8GB DDR4 2133MHz CL15 1.2V 260pin SODIMM HP ProBook 430 G4 470 G4 640 G2 650 G2 655 G3

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.
