NEMIX RAM 128GB (8x16GB) DDR5 4800 CL40 1.1V ECC RDIMM 288-Pin Kit

128GB DDR5 4800 ECC RDIMM Kit

This 128GB kit contains eight 16GB DDR5 4800 registered DIMMs with ECC and a CAS latency of CL40. It operates at 1.1V and uses a 288-pin form factor for compatible server motherboards. The modules are single-rank 1Rx8 and built with major OEM chips for ThinkMate Supermicro SuperServer 521C-NR systems.

DDR5 4800 Registered ECC Limits

DDR5 4800 sets the baseline data rate for fifth-generation double data rate memory at 4800 MT/s. Registered buffering adds a clock cycle to address and command signals, which stabilises large populations of modules but prevents use in platforms that require unbuffered DIMMs. ECC corrects single-bit errors and detects double-bit errors, yet the registered design means these modules will not function in consumer desktop boards that lack registered memory support.

Upgrade From Lower Capacity or Non-ECC DDR5

This kit replaces smaller DDR5 RDIMM sets or non-ECC DDR5 modules when the workload demands 128GB of registered, error-correcting capacity. The jump is worth it when the server platform supports eight DIMM slots at 4800 MT/s and the application requires data integrity across all ranks. Systems limited to fewer slots, lower speeds, or unbuffered memory cannot use this configuration.
