256GB DDR4 3200 ECC RDIMM Kit

This 256GB kit contains sixteen 16GB DDR4 3200 registered DIMMs with ECC and 2Rx8 organisation. It is built for servers and workstations that require error-correcting registered memory. The modules run at 1.2V with a CAS latency of 22.

Registered DIMM Platform Requirements

Each module uses the 288-pin DDR4 RDIMM form factor and presents a registered signal to the memory controller. The platform must support registered ECC DDR4 memory and provide enough DIMM slots for the desired capacity. The kit frees the builder from mixing densities or speeds across channels.

Upgrading From Smaller DDR4 RDIMM Sets

The kit replaces smaller DDR4 RDIMM configurations such as 8GB or 16GB modules when the workload demands 256GB of registered ECC capacity. The jump is worthwhile when the application scales beyond the current memory ceiling and the platform can address the full 256GB.

Questions about this item

What CAS latency will the kit settle at during sustained server workloads?

The modules run at CL22, so latency remains at 22 cycles once the system is fully warmed up.

How much heat and power should I budget for when all sixteen DIMMs run continuously?

Each stick draws 1.2 V at DDR4 3200 speeds, giving low per-module power and modest heat output across the full 256 GB kit.

Which server platform features are required for this registered ECC kit to function?

The motherboard must support DDR4 RDIMM slots, 288-pin layout, registered buffering and ECC capability for the 2Rx8 modules to work.
