System-Specific DDR4 Kit for HP Z640

This 16 GB kit contains two 8 GB registered DIMMs built for the HP Z640 workstation. ECC and registered operation protect data integrity in server-grade workloads. The modules run at 1.2 V with CL15 timings at 2133 MHz.

Sustained Load Behaviour

Registered buffering reduces electrical load on the memory controller during continuous operation. ECC corrects single-bit errors without halting the system. Speed scales down to 1866 MHz when the installed processor limits the memory clock.

Upgrade Context

The kit adds 16 GB to the Z640's eight DIMM sockets, which support up to 128 GB of registered ECC memory. It is not for non-ECC platforms or consumer boards that cannot accept registered modules.

Fragen zu diesem Artikel

How much power does the 1.2V DDR4 2133MHz ECC registered kit draw during continuous operation?

Each module runs at 1.2V; total power depends on the Z640's memory controller and workload, so the kit itself has no separate power-draw rating.

What must the HP Z640 already have for these 288-pin registered DIMMs to function?

The workstation needs a processor that supports DDR4 ECC registered memory and free white DIMM slots for the first DIMM per channel.

Will the memory clock down to 1866MHz if my Z640 uses an 1866MHz-capable processor?

Yes — the processor determines the clock speed, so an 1866MHz CPU will limit the kit to 1866MHz operation.
