1 TB DDR4 2933 ECC LRDIMM Kit

This kit provides one terabyte of DDR4 server memory across eight 128 GB modules. It is built for enterprise servers and workstations that require high-capacity, error-correcting load-reduced DIMMs. Desktop and laptop systems cannot use these modules.

DDR4 2933 LRDIMM limits

The DDR4 2933 interface tops out at this data rate, so throughput cannot exceed the PC4-23400 specification. Load-reduced architecture reduces electrical load on the memory bus, yet the quad-rank 4Rx4 organisation still limits the number of modules each channel can support. CAS latency is fixed at CL21 and voltage at 1.20 V.

Compatibility checklist

Confirm that your server or workstation motherboard accepts DDR4 288-pin LRDIMMs and supports 4Rx4 quad-rank modules at 2933 MHz. Verify the maximum DIMM capacity per slot and the total memory limit per processor. Check the manual for required population order and channel rules before ordering.

Questions about this item

Should I choose the 1TB kit with eight 128GB modules or a different capacity for my server?

This kit provides 1TB total capacity using eight 128GB modules. Verify your server's maximum supported memory and available DIMM slots to confirm this configuration fits your requirements.

What does the DDR4 2933 speed rating mean for real-world server performance?

The modules run at 2933 MHz with CL21 latency, delivering PC4-23400 bandwidth. Actual throughput depends on your processor's memory controller, populated channels, and workload characteristics.

How does the LRDIMM interface affect maximum capacity and speed in practice?

Load Reduced DIMM technology buffers the data bus, allowing the quad-rank 4Rx4 design to operate at 2933 MHz without overloading the memory controller, enabling higher densities per channel.
