Computer Memory Solutions 32GB DDR4 2666 CL19 2Rx8 SODIMM memory upgrade D47

32GB DDR4 2666 SODIMM for HP ZBook workstations

This single 32GB module upgrades compatible HP ZBook 15 G5, ZBook 15 G6 and ZBook 17 G6 mobile workstations. It runs at DDR4 2666 (PC4 21300) with CL19 timing at 1.2V and uses a 2Rx8 unbuffered non-ECC layout on a 260-pin SO-DIMM form factor.

Professionals expanding ZBook memory without ECC

Suits users adding capacity to the listed ZBook models where non-ECC DDR4 SO-DIMM memory is required. Not suited for systems that demand ECC registered modules, such as configurations with Intel Xeon processors, nor for desktops or laptops using full-size DIMM slots or a different DDR generation.

32GB single module with 128GB platform ceiling

One 32GB stick occupies one of four SO-DIMM sockets, leaving room to reach the platform maximum of 128GB when all four slots are populated with matching modules. Performance scales with matched pairs; a single module runs at its rated speed but dual-channel bandwidth is unavailable until a second identical stick is installed.
