Description
NEMIX RAM memory upgrades for the HP Z640 Workstation: DDR4-2400 PC4-19200 ECC Registered (RDIMM) modules, 8GB and 16GB, sold as single modules and matched kits of up to 8, selected as drop-in, compatibility-tested replacements. 1.2V, 288-pin, JEDEC-compliant.
The HP Z640 Workstation is built for one or two Intel Xeon E5-1600 or E5-2600 v3/v4 processors. It has 8 DDR4 DIMM slots and supports up to 128GB with 16GB RDIMMs. HP lists DDR4-2400 registered memory for the Z640; the processor sets the running speed (2400, 2133 or 1866 MT/s). Four slots are on the system board and four on the optional second-processor memory module; a one-processor system has 4 slots (64GB with RDIMMs). For more capacity HP supports 32GB LRDIMMs; RDIMMs and LRDIMMs cannot be mixed. For LRDIMMs, see the HP Z640 LRDIMM listing. Install identical modules in matched sets, following the slot order HP gives for each processor; the system runs memory at the speed its processor supports.
