128 GB DDR5 4800 ECC RDIMM kit

This quad-channel kit delivers 128 GB of DDR5 4800 registered ECC memory across four 32 GB modules. It is built for servers and workstations that require error-correcting, registered DIMMs for data integrity and platform stability.

DDR5 4800 registered ECC platform limits

The modules operate at the standard DDR5 4800 speed with CL40 latency and 1.10 V voltage. Registered ECC RDIMMs only function in server and workstation platforms that explicitly support DDR5 ECC registered memory; they are physically and electrically incompatible with desktop or laptop systems.

288-pin single-rank x4 build quality

Each module uses a 288-pin DIMM form factor with a single-rank x4 (1Rx4) organisation and major-brand chips. The registered design adds a buffer that reduces electrical load on the memory controller, allowing higher capacities per channel while maintaining signal integrity in multi-DIMM configurations.

Questions about this item

Should I choose this 128GB kit of four 32GB modules or a different capacity for my server?

This kit provides 128GB total across four 32GB RDIMMs, designed for quad-channel server and workstation platforms that support DDR5 ECC registered memory.

What does the DDR5 4800 speed rating deliver in a real server workload?

The modules run at 4800 MT/s with CL40 latency at 1.10V, giving registered ECC bandwidth of PC5-38400 for multi-threaded server applications.

How does the 288-pin RDIMM interface and EC8 registered design affect compatibility?

The 288-pin DDR5 RDIMM form factor with single-rank x4 EC8 registration works only in DDR5 server and workstation platforms that explicitly support ECC registered DIMMs.
