Dell-compatible 128 GB DDR4 LRDIMM

This registered 288-pin LRDIMM delivers 128 GB of ECC DDR4 memory for Dell servers. It operates at 2666 MHz with a CAS latency of 15 and runs at 1.20 V. The module uses major-brand DRAM chips and is built to meet OEM specifications.

8Rx4 quad-rank organisation

The 8Rx4 layout packs eight logical ranks per module, allowing a single DIMM slot to provide the full 128 GB capacity. This density is the deciding factor for systems that need maximum memory per channel without exceeding the platform's rank limit.

Fits Dell platforms that accept 128 GB LRDIMMs

Installation requires a motherboard qualified for 288-pin DDR4 LRDIMMs at 2666 MHz with registered ECC support. The module frees additional DIMM slots for future expansion while keeping the server within its existing power and thermal envelope. Builders who need a different rank configuration or non-ECC memory should look elsewhere.

Questions about this item

What does the 2666 MT/s speed mean for my server once the module is installed?

The module runs at DDR4-2666 with CL15 latency, so the memory controller will operate at that data rate and timing, delivering the rated bandwidth for workloads that can use it.

What does the PC4-21300 designation cap in practice?

PC4-21300 is the peak transfer rate label for DDR4-2666; the module cannot exceed that bandwidth, and the platform's memory controller will limit actual throughput to its supported maximum.

Will the 288-pin LRDIMM fit in a standard DDR4 DIMM slot?

Yes, it uses the 288-pin DDR4 LRDIMM form factor, which is keyed for registered DDR4 server slots; the notch position matches the DDR4 standard.
