64 GB DDR4 ECC UDIMM kit for servers

This 64 GB kit contains four 16 GB DDR4 2400 MHz ECC UDIMM modules. It is built for servers and workstations that require error-correcting unbuffered memory. It is not compatible with standard desktop or laptop computers.

Dual-rank 2Rx8 organisation

Each module uses a 2Rx8 dual-rank x8 organisation and runs at the standard DDR4 voltage of 1.2 V. The CL17 latency and PC4-19200 rating deliver the rated bandwidth for supported platforms.

288-pin DIMM installation with channel guidelines

The 288-pin DIMM form factor fits compatible DDR4 server and workstation slots. Follow the system manual for correct seating order and channel population. Mixing ranks or skipping slots can prevent the system from posting.

Questions about this item

Will the dual-rank 2Rx8 modules need any firmware updates or reconfiguration when I add more memory later?

The 2Rx8 organisation is fixed on each 16 GB module; adding further kits only requires the motherboard to support the total capacity and rank count.

What electrical or thermal limit appears first when all four sticks run at 2400 MHz continuously?

Each module operates at the standard 1.2 V DDR4 voltage, so the platform’s memory-controller power budget and DIMM-slot cooling capacity become the limiting factors.

How much heat and fan noise should I expect from the 64 GB kit under 24/7 server workloads?

Unbuffered ECC DDR4 at 1.2 V produces modest heat; typical server chassis airflow keeps temperatures low and adds no audible fan noise beyond the system’s normal cooling.
