They are the same generation at three sizes. The Z440 is a single-socket tower for CAD and modelling. The Z640 can run one or two processors in a mid-sized case. The Z840 is the full dual-socket model with the most memory, drive bays and expansion slots. All three use Xeon E5 v3/v4 processors and DDR4 ECC memory.

For light workloads and tight budgets, yes. Both use the older Xeon E5 v1/v2 platform with DDR3 ECC memory, so they are slower and less efficient than the Z440 and Z840. They remain capable for 2D CAD, training rooms, lab machines and general office use where a solid tower matters more than speed.

The Z640 is designed to run one or two processors, so a single-processor unit can be expanded. The second processor needs matching hardware and a processor of the same model. Send the serial number and the processor you have, and the team will confirm what is needed before you order.

No. HP split in 2015 into HP Inc., which makes PCs, printers and Z workstations, and Hewlett Packard Enterprise, which makes ProLiant servers and enterprise storage. Z workstations are HP Inc. products. The difference matters when you look up drivers, BIOS updates and documentation.

It depends on the model and generation. The Z420 and Z820 use DDR3, while the Z440, Z640 and Z840 use DDR4, and graphics cards are limited by size, slot and power connectors. We do not assume compatibility. Send the serial number and the parts you want to fit, and the team will confirm before you order.
