HP Z440 server memory kit

This 32 GB kit contains four 8 GB DDR4 registered DIMMs validated for the HP Z440 workstation server. ECC error correction and registered signalling provide the data integrity required by professional workloads. The modules run at 1.2 V and fit the system's 288-pin slots.

Capacity and headroom

Four modules deliver 32 GB total, leaving four of the eight DIMM sockets free for future expansion up to the platform maximum of 128 GB. The single-rank x4 organisation keeps each channel lightly loaded at this capacity. Applications needing more than 128 GB will exceed the supported limit.

Thermals and power

Operating at 1.2 V without heat spreaders, the sticks rely on the workstation's directed airflow for cooling. Registered buffering adds minimal latency while reducing electrical load on the memory controller. Power draw stays low during typical server duties such as virtualisation or database hosting.

Questions about this item

Can these 2133 MHz registered ECC DIMMs mix with the DDR4 modules already in my Z440?

The kit provides four 8 GB DDR4-2133 registered ECC DIMMs at 1.2 V with CL15 timing; the Z440 server supports up to 128 GB of registered ECC RDIMMs across eight sockets, so adding this 32 GB kit leaves four slots free for existing modules.

How can I verify the memory is running at 2133 MHz with ECC active after installation?

Enter the system BIOS or use a hardware information utility; it should report each DIMM as 8 GB DDR4-2133 (PC4-17000) registered ECC, 1Rx4, CL15, at 1.2 V, and show the total capacity as 32 GB plus any previously installed memory.

What comes in the box and is anything else required to use them?

The package contains four 288-pin DDR4 registered ECC DIMMs; no heat spreaders, cables or additional hardware are included or required for installation in the compatible HP Z440 server.
