128GB DDR5 ECC UDIMM Kit

This 128GB kit contains four 32GB DDR5-5600 ECC UDIMM modules built for servers and workstations that require error-correcting unbuffered memory. It suits administrators expanding memory capacity on platforms validated for 288-pin PC5-44800 EC4 DIMMs at 1.10V.

Sustained Load Behaviour

Dual-rank 2Rx8 organisation and CAS 40 timings allow each module to maintain throughput during extended compute or virtualization tasks without the buffering latency of registered DIMMs. ECC correction operates continuously to preserve data integrity under heavy multi-threaded workloads.

DDR5 Interface Limits

The PC5-44800 standard caps transfer rate at 5600 MT/s and mandates 1.1V operation, so this kit cannot exceed those speeds or voltages on any platform. Compatibility is restricted to systems explicitly qualified for DDR5 ECC UDIMM; desktop and laptop boards that lack EC4 support will not accept these modules.

Questions sur cet article

How much power does the 1.10V DDR5-5600 kit draw under sustained server workloads?

The modules run at the standard DDR5 voltage of 1.10V. Actual power draw depends on the server platform and workload intensity, so consult your system documentation for precise figures.

What motherboard features are required to run this 288-pin ECC UDIMM kit?

You need a server or workstation board with DDR5 slots that support ECC unbuffered DIMMs and quad-channel operation. Desktop and laptop platforms are not compatible.

Will the dual-rank 2Rx8 organisation work alongside older single-rank DDR5 modules I already own?

Mixing ranks is possible only if the platform's memory controller and BIOS explicitly support mixed-rank populations. Check the system manual for approved configurations before combining modules.
