Compatible Z440 Server Memory Kit

This 64GB kit contains four 16GB DDR4 ECC registered DIMMs built for the HP Z440 server. Each module runs at 2133MHz with CL15 timing at 1.2V. The registered design and ECC support suit workloads that demand data integrity and multi-module stability.

Verify Processor Speed And Slot Plan

The Z440 clocks memory to the processor’s capability; an 1866MHz CPU will limit these modules to 1866MHz. The system provides eight DIMM sockets with a 128GB registered maximum, so confirm available slots and current population before ordering. White slots mark the first DIMM per channel for single-DIMM-per-channel configurations.

Standard Voltage Registered Thermals

Operating at the standard 1.2V DDR4 voltage, these registered modules draw typical power for server DIMMs of this density. Heat-spreader presence varies by inventory, so airflow across the memory zone should follow the workstation’s standard cooling guidance. Acoustic impact is governed by the system fans rather than the memory itself.

Questions about this item

Does the kit contain four 16 GB modules or do I need to buy extra sticks?

The kit ships with four 16 GB DDR4 modules, giving 64 GB total, so no additional sticks are required.

Should I choose the 64 GB kit or a smaller capacity for my Z440 server?

The Z440 server supports up to 128 GB of registered ECC memory across eight slots, so this 64 GB kit fills half the capacity and leaves room for future expansion.

Will the memory actually run at 2133 MHz once installed in my Z440?

The modules are rated for 2133 MHz, but the installed processor determines the final speed; an 1866 MHz capable CPU will limit the memory to 1866 MHz.
