32GB DDR4 2133 ECC RDIMM Kit

This 32GB kit contains two 16GB DDR4 2133 registered DIMMs with ECC and CL15 latency. It operates at the standard 1.20V voltage and uses a dual-rank x4 organisation across 288 pins. The modules are built for servers and workstations that require registered memory and will not function in standard desktop or laptop systems.

Registered ECC with Dual-Rank Layout

The registered buffer reduces electrical load on the memory controller, allowing larger capacities per channel while ECC corrects single-bit errors to protect data integrity. The 2Rx4 configuration increases bank density for heavier workloads. Together these features change how the system handles memory stress compared to unbuffered non-ECC alternatives.

Suited for DDR4 Servers and Workstations

This kit suits administrators upgrading compatible DDR4 servers or workstations that specifically call for registered ECC RDIMMs. It is not for desktop PCs, laptops or any platform that accepts only unbuffered memory. Buyers needing higher speeds, different capacities or non-ECC modules should look at other product lines.

Questions about this item

Will the registered DIMM modules require any firmware updates or periodic replacement to maintain ECC error correction?

The modules operate at standard 1.2V DDR4 voltage with major-brand chips and undergo quality-assurance testing; no firmware updates or scheduled replacement are needed for ECC functionality.

What is the first limit reached when the 2Rx4 dual-rank modules run at 2133 MHz under sustained server workloads?

The CL15 CAS latency at DDR4 2133 (PC4-17000) sets the timing boundary that appears before bandwidth or thermal limits during continuous operation.

How much heat and power do the two 16 GB sticks draw when the server runs all day at 1.2V?

Each module runs at the standard 1.20V DDR4 voltage, so total power draw stays at the JEDEC baseline for 32 GB of registered memory with no extra cooling required.
