System-specific DDR3 for HP Z workstations

This 8GB DDR3 ECC registered DIMM is built for second-generation HP Z420, Z620 and Z820 workstations. It targets professionals who need reliable server-grade memory to expand or replace modules in those platforms. The single-module kit keeps upgrades simple and cost-effective.

ECC registered 2Rx4 at 1.5V

The module runs at DDR3 1600 (PC3-12800) with CL11 latency and a 2Rx4 dual-rank organisation. ECC registration is mandatory for these workstations; the module will not work in systems that require unbuffered ECC or non-ECC memory. Voltage is fixed at 1.50V.

Straightforward DIMM installation

The 240-pin DIMM seats in standard DDR3 slots without tools. Consult the workstation manual for correct channel population and seating order. Mixing speeds is possible but the system will run at the slowest module. No heat spreader is fitted, so airflow around the slots should be adequate.

Questions about this item

What does the 1600MHz speed mean once the module is installed in an HP Z420, Z620 or Z820?

The DIMM operates at 1600MHz PC3-12800; the system will run at the speed of the slowest installed module.

How does the registered ECC interface affect what the workstation can use?

This is an ECC Registered RDIMM (2Rx4) and must not be mixed with ECC Unbuffered UDIMM modules in the same system.

What physical slot and pin count does this 8GB module need to fit?

It requires a 240-pin DDR3 DIMM slot on the HP Z420, Z620 or Z820 motherboard.
