High-capacity registered DDR4 module

The RIMLANCE RRD25600DD4C128 is a single 128GB DDR4 3200 registered DIMM built for servers and workstations that require maximum memory density per slot. ECC protection and registered buffering help maintain data integrity under sustained heavy workloads.

288-pin form factor and major-brand DRAM

The module uses a standard 288-pin DDR4 interface and is assembled with DRAM chips sourced from Samsung, SK Hynix or Micron. Each unit undergoes individual inspection and testing before shipment to ensure reliable installation in qualified platforms.

Low-voltage operation at CL22

Rated at 1.2V with a CAS latency of 22, the DIMM runs within the standard DDR4 power envelope for its speed grade. Registered buffering reduces electrical load on the memory controller, contributing to stable thermals in densely populated chassis.

Questions about this item

What does DDR4 3200 PC4-25600 mean for real-world throughput?

The module runs at 3200 MT/s, giving a peak bandwidth of 25600 MB/s; actual throughput depends on the server's memory controller and channel configuration.

What physical slot and clearance does the 288-pin registered DIMM need?

It requires a standard 288-pin DDR4 RDIMM slot; the registered design adds a small buffer chip, so verify heatsink clearance in dense chassis.

How is the module installed and what step is often missed?

Align the notch with the slot key, press firmly until both retention clips click, then confirm in BIOS that the registered ECC module is detected at 3200 MT/s.
