Server Memory Upgrade

This 64GB DDR4 2133 MHz ECC LRDIMM module is built for servers and workstations that require registered load-reduced memory. It is not compatible with standard desktop or laptop platforms. The quad-rank 4Rx4 organisation lets a single DIMM deliver high capacity for memory-intensive workloads.

Sustained Workload Behaviour

ECC error correction maintains data integrity during long compute runs, while the load-reduced buffer lowers electrical load on the memory controller. At CL15 latency and 1.20V the module delivers steady throughput without the voltage scaling needed for higher speeds. The Major Brand Chipset supports consistent operation across fully populated channels.

Thermals Noise Power

Standard 1.2V DDR4 voltage keeps power draw predictable inside dense server chassis. Passive operation means no fan noise is added by the module itself. The 288-pin form factor fits industry-standard DIMM slots, allowing normal airflow across the PCB.

Questions about this item

How much power does the 64GB DDR4 2133 LRDIMM draw at its rated 1.20V voltage?

The module operates at the standard DDR4 voltage of 1.20V. As a Load Reduced DIMM, it reduces electrical load on the server memory bus, which helps system power efficiency when fully populated.

Does my server motherboard need specific LRDIMM support to use this 288-pin quad-rank module?

Yes, this 288-pin DDR4 ECC LRDIMM requires a server or workstation platform that explicitly supports Load Reduced memory. It is not compatible with standard desktop or laptop computers.

Can I mix this 4Rx4 PC4-17000 stick with older DDR4 2133 RDIMMs in the same server?

Mixing LRDIMMs and standard RDIMMs is generally not supported by server platforms. This quad-rank Load Reduced module should be installed in a homogeneous configuration per the system manufacturer's guidelines.
