Computer Memory Solutions 16GB (2x8GB) DDR4 2400MHz CL17 SODIMM C109

HP ProBook DDR4 Upgrade

This 16 GB kit contains two 8 GB DDR4-2400 SO-DIMM modules built for HP ProBook 430 G3, 430 G4, 440 G3 and 440 G4 notebooks. It targets owners of those models who need the maximum 16 GB capacity supported by the two available memory slots. The unbuffered, non-ECC sticks run at 1.2 V with CL17 timing and use major-brand DRAM chips.

Replacing Factory 4 GB or 8 GB Modules

Most units shipped with a single 4 GB or 8 GB stick, leaving one slot empty or capping total memory below the platform limit. Installing this matched pair fills both sockets and reaches the 16 GB ceiling in one step, which is worthwhile when multitasking, virtual machines or large spreadsheets regularly exhaust the original amount. Buyers whose workloads stay within 8 GB will not see a benefit.

Sustained Load Behaviour

Without a heat spreader the modules rely on the notebook’s internal airflow, yet the low 1.2 V voltage and standard CL17 latency keep thermals modest during extended compile, render or database sessions. The 2Rx8 organisation provides two ranks per DIMM, allowing the memory controller to interleave accesses and maintain steady throughput over long periods rather than throttling after a short burst.
