System-specific DDR4 kit

This 16 GB kit contains two 8 GB registered DIMMs built for the HP Z440 workstation. Each module runs at DDR4 2133 with CL15 timing at 1.2 V and includes ECC error correction. The registered design reduces electrical load on the memory controller in multi-socket server configurations.

Fits eight registered slots

The Z440 accepts up to 128 GB across eight ECC RDIMM sockets and this kit occupies two of them. White DIMM slots mark the first slot of each channel; for single-DIMM-per-channel population the white slots are used first. Memory speed scales to the installed processor, dropping to 1866 MHz when an 1866 MHz-capable CPU is fitted.

Steady throughput under load

Registered buffering and ECC maintain data integrity during sustained compute tasks. The modules operate at standard 1.2 V DDR4 voltage and clock down automatically to match the processor’s supported rate, preventing instability when all channels are populated. Rank configuration is 2Rx8 per DIMM.

商品問答

Will the CL15 timing limit throughput when the system runs at the full 2133 MHz speed?

The kit is rated CL15 at 2133 MHz, so the rated latency is already validated for the top supported frequency.

Do the registered ECC DIMMs draw more power or generate extra heat during continuous 24/7 server workloads?

Each module operates at the standard DDR4 1.2 V, so power draw and thermal output match typical registered DDR4 DIMMs under sustained load.

Does the Z440 workstation require a specific processor to run this 2133 MHz kit at its rated speed?

Yes — the system clocks memory to the processor capability; an 1866 MHz-capable CPU will limit the kit to 1866 MHz.
