32GB DDR4 ECC Registered Kit

This 32GB kit contains two 16GB DDR4 ECC registered DIMMs running at 2133MHz with CL15 timing. It is built for the HP Z440 workstation and operates at 1.2V using a 288-pin interface. The registered design and ECC support target professional workloads that require data integrity and server-class stability.

Two-Module Population and Speed Scaling

The pair fills two of the eight available registered DIMM slots, leaving room to reach the platform maximum of 128GB. Actual operating speed follows the installed processor; an 1866MHz-capable CPU will clock the memory down to 1866MHz. White DIMM slots mark the first slot of each channel for correct single-DIMM-per-channel population.

Major Brand Chipset and Variable Heat Spreader

Modules use a major-brand chipset in a 2Rx4 organisation and may ship with or without a heat spreader depending on current inventory. The registered buffer reduces electrical load on the memory controller, supporting reliable operation in fully populated configurations. No additional accessories or software are included beyond the two DIMMs.

Questions sur cet article

Will the 288-pin DDR4 DIMMs need any periodic maintenance or replacement during normal server operation?

No scheduled maintenance is required for the registered ECC modules; they are rated for continuous operation at 1.2 V with a limited lifetime warranty from the manufacturer.

What limit appears first when the kit runs at full 2133 MHz load in the Z440 workstation?

The processor’s memory controller caps the speed; with an 1866 MHz capable CPU the modules will clock down to 1866 MHz regardless of their 2133 MHz rating.

How much heat and power do the two 16 GB sticks draw when the workstation runs all day?

Each module operates at 1.2 V with CL15 15-15-15 timing; registered ECC DDR4 at this voltage typically stays cool under sustained load without active cooling.
