16GB DDR4 2133MHz ECC LRDIMM Module

This 16GB DDR4 2133MHz ECC LRDIMM module is built for servers and workstations that require registered memory with error correction. The load-reduced design lowers electrical load on the memory controller, allowing higher capacities per channel. It operates at 1.2V standard DDR4 voltage with CL15 latency.

288-Pin DIMM Build and Major Brand Chips

The module uses a standard 288-pin DIMM form factor and major brand chips tested for dependable operation in multi-module server configurations. Load-reduced buffering means the memory controller sees less signal loading, which helps stability when populating multiple slots. ECC circuitry detects and corrects single-bit errors to protect data integrity.

DDR4 2133MHz Speed and Platform Constraints

The DDR4 2133MHz (PC4-17000) interface sets the maximum data rate this module can deliver; systems limited to lower speeds will downclock automatically. Load-reduced DIMMs require motherboards and CPUs that explicitly support LRDIMM technology — standard registered DIMM slots will not accept them. Verify your platform's qualified vendor list before installation.

Questions about this item

What DDR4 speed does this PC4-17000 LRDIMM actually run at?

The module operates at DDR4 2133 MHz, which is the PC4-17000 data rate; the memory controller will not exceed this frequency.

What physical slot and pin count does this 2Rx4 ECC LRDIMM require?

It fits a standard DDR4 DIMM socket with 288 pins; the motherboard must support load-reduced DIMMs, not just registered ones.

How is this ECC LRDIMM installed and what step do builders often miss?

Power down, open the chassis, align the notch with the 288-pin slot, press firmly until both latches click, then enable ECC in the BIOS or the error-correction will stay inactive.
