HP Z820 DDR3 ECC kit

This kit provides 16 GB of DDR3 ECC memory in four 4 GB unregistered DIMMs built for the HP Workstation Z820. It suits technicians upgrading or repairing that specific workstation platform.

DDR3 1333 speed ceiling

The modules run at 1333 MHz with CL9 timing and 1.5 V. The Z820 accepts 1066 MHz, 1333 MHz or 1600 MHz depending on the processor installed, so this kit will operate at its rated speed only with a compatible CPU.

Four-slot unregistered limit

The workstation supports up to 64 GB of unbuffered ECC across its 16 sockets, but mixing unregistered and registered DIMMs is not supported. Builders needing more than 64 GB or registered memory must choose a different configuration.

Spørgsmål om denne vare

Should I pick the 16GB (4×4GB) kit or a single 4GB module for my Z820?

The Z820 has 16 DIMM slots in 8 banks of 2; the 16GB kit fills four slots at once and keeps each bank balanced, while a single 4GB stick leaves the other slot in that bank empty and limits total capacity.

What does the 1333MHz rating deliver once the modules are installed in the Z820?

The system runs the memory at 1333MHz when the installed processor supports that speed; otherwise it steps down to 1066MHz, so actual throughput depends on the CPU model.

Is this DDR3-10600 ECC UDIMM limited by the Z820's memory controller?

Yes — the Z820 accepts both registered and unbuffered ECC DDR3 but will not mix them; the kit's 1.5V unbuffered modules run at 1333MHz or 1066MHz as the processor allows, up to the 64GB unbuffered maximum.
