Server DDR4 RDIMM kit

This 64GB kit contains four 16GB DDR4 2400 ECC registered DIMMs built for servers and workstations that require registered memory. Each module runs at CL17 latency and 1.2V standard voltage using single-rank x4 organisation. The 288-pin form factor fits only platforms designed for DDR4 RDIMM memory.

Registered ECC 288-pin design

Registered buffering and ECC error correction work together to maintain data integrity under sustained workloads in multi-socket systems. The quad-channel kit populates four slots simultaneously, so the memory controller can interleave traffic across all modules. Single-rank x4 chips keep electrical loading low per channel, helping stability when all slots are filled.

Upgrade from smaller RDIMM sets

Adding this kit replaces lower-capacity registered kits or mixed-rank modules to give a matched quad-channel population. The jump is worthwhile when your workload exceeds the current memory ceiling and the platform supports DDR4 2400 registered DIMMs. Desktop and laptop systems cannot use these modules.

Questions about this item

Does this DDR4 2400 (PC4-19200) kit run at the rated speed on any server board that lists DDR4 2400 support?

Speed will follow the highest JEDEC DDR4 2400 profile the platform enables; some systems may default to a lower data rate until the correct memory mode is selected in firmware.

What physical slot and keying do these 288-pin RDIMMs require?

They fit standard DDR4 RDIMM sockets with the registered DIMM key notch; desktop UDIMM or SO-DIMM slots will not accept them.

What is the correct way to populate the four modules for quad-channel operation?

Install one module per channel following the motherboard's population sequence (for example CPU1 slots A1, B1, C1, D1) so each channel receives a single 1Rx4 rank.
