128 GB DDR4 server kit

This 128 GB kit contains four 32 GB DDR4 2400 modules built for servers and workstations that require ECC load-reduced memory. The quad-rank x4 organisation and registered design let compatible platforms address large capacities across four channels. Desktop and laptop systems cannot use these modules.

ECC load-reduced operation

On-die error correction detects and corrects single-bit errors while the load-reduced buffer lightens the electrical load on the memory controller. This combination allows the platform to populate all slots at rated speed without signal degradation, improving data integrity for virtualisation, databases and other memory-intensive workloads.

288-pin DIMM build quality

Each module uses major-brand chips on a standard 288-pin DDR4 PCB tested to the supplier's quality-assurance programme. The 1.2 V operating voltage matches the DDR4 specification, and the quad-channel kit simplifies balanced population across supported server boards. Verify your system manual for correct slot placement before installation.

Questions about this item

How do I replace a failed module in the 128GB quad-channel kit?

Each 32GB LRDIMM uses a 288-pin DDR4 form factor; remove the faulty stick and insert a matching 4Rx4 ECC Load Reduced module at 2400 MHz and 1.20V to keep quad-channel operation.

What limits sustained throughput on these 4Rx4 LRDIMMs?

The CL17 latency at DDR4 2400 (PC4-19200) sets the timing ceiling, while the quad-rank x4 organisation caps maximum density per channel on supported server platforms.

How much heat and power do four 32GB LRDIMMs draw under continuous load?

Four modules at the standard 1.2V DDR4 voltage draw modest power; load-reduced buffering lowers electrical load on the memory bus, so typical server airflow handles the resulting heat without extra cooling.
