128GB DDR5 ECC UDIMM kit

This 128GB kit contains four 32GB DDR5 4800 modules with CL40 timing and 1.1V operation. It targets servers and workstations that require error-correcting unbuffered memory for data integrity.

Four ranks of 2Rx8 density at PC5-38400

Each module uses a 2Rx8 organisation, giving the kit high capacity per slot. The DDR5 4800 speed handles typical enterprise workloads, while CL40 latency and 1.1V voltage define the performance envelope.

288-pin DDR5 ECC unbuffered form factor

The modules fit standard 288-pin DDR5 UDIMM slots without heat spreaders. They require a platform that supports DDR5 ECC unbuffered memory and leave adjacent slots free for further expansion.

Questions about this item

Can the 4800 MT/s ECC UDIMMs run alongside slower DDR5 modules already in the server?

All DDR5 modules in a system operate at the speed of the slowest installed kit, so existing slower DDR5 will reduce these 4800 MT/s modules to that lower rate.

How can I confirm the kit is running at the rated 4800 MT/s with CL40 timings after installation?

Check the memory speed and latency reported in the BIOS or a tool such as CPU-Z; they should show 4800 MT/s and CL40 when the kit is operating as specified.

Does the 4 x 32 GB kit include only the four UDIMMs, or are any cables or brackets supplied?

The package contains the four 288-pin DDR5 ECC UDIMMs and nothing else; no cables, brackets or additional hardware are included.
