Memory upgrades matched to your HP Z workstation. Each listing covers one HP Z model and one memory type, with the speed, module sizes and kit sizes HP specifies for that model. To find yours, type the model into the search bar at the top of the page, for example Z4 G4, Z8 G4, Z2 Tower G9, Z2 Mini G5 or Z840. For help identifying your workstation, see the HP workstation memory guide.

ECC or non-ECC?
Z4, Z6, Z8 and ZCentral workstations use registered ECC memory. Z2 and Z240 systems take ECC memory with a supporting processor (Xeon, and some Core models) and non-ECC memory otherwise; HP does not support mixing the two. Match what is installed, or replace all modules at once.
