Kit capacity and target systems

This 256 GB kit contains two 128 GB DDR4 2400 modules built as ECC load-reduced DIMMs for servers and workstations. The octal-rank 3DS design lets compatible platforms address very high memory densities per slot. It is not suitable for desktop or laptop computers.

Installation notes

The 288-pin DIMMs install like standard registered memory but require a motherboard that supports LRDIMM and the 2S4Rx4 rank structure. Mis-seating or placing modules in unsupported channels is the most common cause of boot failure; always follow the system manual for population rules.

Who this suits and who should look elsewhere

Suits administrators expanding memory in qualified DDR4 servers that accept 128 GB ECC LRDIMMs per slot. Builders needing non-ECC memory, desktop form factors, higher speeds, or capacities beyond what their platform qualifies should choose a different kit.

Questions sur cet article

How can I confirm the 256GB DDR4 2400 ECC LRDIMM kit is running at the correct 2400 MHz speed and CL17 latency after installation?

Enter the system BIOS or UEFI and verify the memory frequency reads 2400 MHz with CAS latency 17; the modules operate at 1.20V standard DDR4 voltage, and the ECC Load Reduced function will be reported by the server management interface if the platform supports it.

What exactly ships in the 256GB dual-channel kit and are any extra parts required for installation?

The box contains two 128GB 288-pin DDR4 ECC LRDIMM modules (2S4Rx4 octal-rank 3DS/TSV); no heat spreaders, cables or additional hardware are included, and nothing else must be purchased separately provided the server has free 288-pin DDR4 DIMM slots.

Should I choose this 256GB (2x128GB) 2S4Rx4 DDR4 2400 ECC LRDIMM kit or a different capacity or rank configuration?

Select this kit when your server or workstation specifically supports 128GB DDR4 ECC Load Reduced DIMMs with 2S4Rx4 octal-rank 3DS/TSV organisation and you need a matched 256GB dual-channel pair; otherwise choose a capacity and rank layout listed in your system's qualified-vendor list.
