128 GB DDR4 ECC UDIMM kit

This 128 GB kit contains eight 16 GB DDR4 modules rated at 2400 MHz with CL17 latency and 1.20 V operation. It is built for servers and workstations that require ECC unbuffered memory in a 288-pin DIMM form factor.

Installation notes

Modules install like standard DIMMs but must go into platforms that explicitly support DDR4 ECC UDIMM 2Rx8 configuration; desktop and laptop boards will not accept them. Verifying the system manual for correct channel population avoids the most common seating errors.

Sustained workload behaviour

ECC corrects single-bit errors on the fly, keeping data integrity intact during long compute runs or heavy virtualisation loads. Dual-rank organisation helps maintain throughput when all eight slots are populated under continuous demand.

Questions about this item

How can I verify the 128GB kit is running at the rated DDR4 2400 speed after installation?

Enter the system BIOS or use a tool such as CPU-Z; the memory tab should show 2400 MHz and CL17 timings for each of the eight 16GB modules.

What exactly ships in the box and is anything else required to install the modules?

The box contains eight 16GB DDR4 2400 ECC UDIMM 2Rx8 modules; no extra cables, brackets or software are needed, only a compatible server or workstation with 288-pin DDR4 slots.

Should I choose this 128GB 2Rx8 kit or a different capacity for my DDR4 2400 server?

Select this 8x16GB kit when your platform supports 128GB of unbuffered ECC memory and you want dual-rank x8 modules; choose a smaller kit if your board has fewer slots or a lower maximum capacity.
