Z620 Registered ECC Memory Kit

This 32 GB kit contains four 8 GB DDR3L 1600 registered ECC DIMMs built for the HP Z620 workstation. It targets professionals who need error-correcting memory for stable compute workloads on that platform. The modules run at 1.35 V with CL11 timing and are validated for the system’s registered memory channels.

Capacity and Headroom

The Z620 accepts up to 192 GB of registered ECC memory across twelve sockets, so this 32 GB kit leaves ample room for future expansion. Quad-channel performance is achieved when like modules are installed in banks of four, matching the configuration supplied here. Speeds of 1066, 1333, 1600 and 1866 MHz are supported depending on the installed processor; this kit operates at the 1600 MHz rating.

Upgrade Path

The kit replaces lower-capacity or unbuffered ECC modules that limit the workstation to 96 GB and prevent mixing with registered DIMMs. Moving to registered memory unlocks the full 192 GB ceiling and twelve-slot capacity of the Z620. The jump is worthwhile when workloads demand more than 96 GB or require the signal integrity of registered modules for sustained operation.

Questions about this item

Will this 240-Pin DDR3L 1600 kit run reliably in a Z620 that currently uses 1066 MHz or 1333 MHz modules?

The Z620 supports 1066, 1333, 1600 and 1866 MHz speeds depending on the installed processor; mixing RDIMM and UDIMM is not supported, so this registered kit will run at the highest common speed the CPU allows.

How can I verify the four 8 GB sticks are operating as registered ECC at 1.35 V after installation?

Check the BIOS memory information or OS hardware monitor for 32 GB total, ECC active, registered mode, CL11 timings and 1.35 V reported voltage.

What exactly ships in the box and is any extra hardware required for the Z620?

The package contains four 8 GB 240-Pin DDR3L registered ECC DIMMs; no additional brackets, cables or cooling are needed for the Z620's 12 DIMM sockets.
