128GB DDR5 4800 ECC RDIMM

This 128GB registered DDR5 module targets IT professionals upgrading THINKMATE Supermicro SuperServer platforms such as the 111C-NR and 121C-TN2R. It delivers error-correcting registered memory for mission-critical server and workstation environments requiring maximum single-slot capacity.

DDR5 4800 registered interface limits

The DDR5 4800 standard operates at 1.10V with a CAS latency of CL40 and a 4Rx4 rank structure. Registered buffering adds a clock cycle for address and command signals, which stabilises large memory arrays but prevents use in unbuffered consumer motherboards that lack registered DIMM support.

Capacity headroom for dense workloads

A single 128GB module provides substantial headroom for virtualisation hosts, in-memory databases and large-scale analytics. The four-rank organisation maximises density per slot, yet total system capacity remains constrained by the server memory-controller channel limits and the number of available 288-pin RDIMM sockets.

Questions about this item

Should I pick a single 128 GB module or multiple smaller modules to reach 128 GB?

The listing supplies one 128 GB stick, so capacity is fixed at that density; add additional identical modules only if your board has free slots and the memory controller supports the total rank count.

What does the 4800 MT/s rating deliver once the module is installed in a server?

The module runs at DDR5 4800 with CL40 latency, providing the standard JEDEC data rate for registered ECC workloads without overclocking.

How does the 288-pin DDR5 RDIMM interface limit usable bandwidth?

The 288-pin registered DIMM connects through the DDR5 memory controller at up to PC5-38400, so peak throughput is capped by that bus specification and the CL40 timing.
