Dell-compatible 32 GB DDR4-2133 ECC LRDIMM with CL15 latency, 1.2 V operation and 4Rx4 organisation for server upgrades
This module is a Dell-compatible 32 GB DDR4-2133 load-reduced DIMM built for server platforms that require ECC memory. It operates at 1.2 V with a CL15 latency and a 4Rx4 organisation across 288 pins. The part matches Dell part number KVTD4 and uses major-brand DRAM from Samsung, SK Hynix or Micron.
The 32 GB density provides substantial memory headroom for virtualisation hosts, database workloads and memory-intensive applications running on supported Dell servers. Four-rank organisation maximises capacity per slot, though total system capacity remains limited by the platform's memory-controller and slot count.
The DDR4-2133 interface delivers up to 17 000 MB/s of theoretical bandwidth per module, which becomes the ceiling for memory-bound tasks. Higher-speed DDR4 modules will down-clock to this rate when mixed, and platforms that only support registered DIMMs cannot use load-reduced modules without explicit qualification.

Mixing load-reduced and registered DIMMs is not supported by Dell platforms; all slots must use the same memory technology for the server to POST and run stably.
Enter the system BIOS or iDRAC interface and verify the memory shows 2133 MT/s, CL15, 1.20 V and ECC enabled for each installed module.
The module ships as a single 288-pin LRDIMM; no cables, brackets or additional components are included or required for installation.
