128 GB DDR4 ECC RDIMM kit

This 128 GB kit contains two 64 GB registered DIMMs built for DDR4 servers and workstations. Each module runs at 2933 MHz with CL21 latency at 1.20 V. The dual-rank x4 organisation and on-board ECC protect data integrity in multi-socket platforms. It is not compatible with desktop or laptop computers.

Registered 288-pin build with major-brand chips

The 288-pin RDIMM form factor fits standard DDR4 server slots and the registered buffer reduces electrical load on the memory controller. Major-brand DRAM chips are used throughout and every module undergoes quality-assurance testing before shipment. Dual-channel packaging lets you populate matched pairs for optimal throughput.

Upgrade path for capacity-bound DDR4 platforms

This kit replaces lower-capacity DDR4 RDIMMs when workloads exceed the memory ceiling of the current configuration. The jump is worth it when virtualisation, database or compute tasks trigger swapping or limit concurrent jobs. Verify your system's qualified-vendor list and maximum supported density per slot before ordering.

Questions about this item

What DDR4 standard and speed rating does this kit use?

The kit is rated DDR4 2933 MHz with a PC4-23400 designation, delivering 2933 MT/s on compatible server platforms.

What physical slot and module dimensions are required?

Each module is a 288-pin DDR4 RDIMM; the system must provide registered DIMM slots that accept 288-pin DDR4 memory.

How are the two modules installed for dual-channel operation, and what step is often missed?

Install one module per memory channel following the motherboard’s channel-population guide; the common mistake is placing both modules in the same channel instead of splitting them across channels.
