128GB DDR4 ECC Registered Kit

This 128GB kit contains two 64GB DDR4 2400 modules built for servers and workstations that require ECC registered memory. The dual-channel configuration adds capacity while maintaining signal integrity through the registered buffer.

Quad-rank 3DS stacking and 288-pin form factor

Each module uses 2S2Rx4 quad-rank x4 organisation with 3DS through-silicon via stacking to reach 64GB density on a standard 288-pin DIMM. Registered buffering reduces electrical load on the memory controller, a requirement for multi-DIMM server boards.

DDR4 2400 CL17 at 1.2V defines the operating

The modules run at PC4-19200 speed with CAS latency 17 and standard 1.2V DDR4 voltage. Compatibility is limited to platforms that explicitly support DDR4 ECC registered DIMMs with quad-rank 3DS topology; desktop and laptop systems cannot use this memory.

Soalan tentang produk ini

Does the PC4-19200 rating on these DDR4 2400 modules limit the throughput in a single-channel server slot?

The PC4-19200 rating matches the DDR4 2400 speed of each 64 GB module; actual throughput depends on the server's memory controller and channel configuration.

What physical slot and clearance do the 288-pin ECC RDIMM modules need in a server chassis?

Each module uses a standard 288-pin DDR4 DIMM slot; verify the motherboard supports 3DS/TSV quad-rank RDIMMs and that heatsink height clears the module.

What is the correct installation sequence for this dual-channel 2x64 GB kit, and which step is commonly missed?

Populate the two modules in the motherboard's designated dual-channel slots (usually same-coloured banks), seat each until the retention clips lock, then confirm the BIOS recognises 128 GB at DDR4 2400 with ECC active.
