32 GB DDR4-2133 ECC load-reduced DIMM for Dell servers, CL15 at 1.20 V
This 32GB DDR4-2133 PC4-17000 module is a load-reduced DIMM with ECC and a 4Rx4 organisation. It operates at 1.20V with a CAS latency of 15. The part is built with major-brand DRAM and is validated as a direct replacement for Dell part number A7946646. It targets administrators upgrading compatible Dell PowerEdge platforms.
Confirm that your server platform accepts DDR4 LRDIMM modules and specifically supports 4Rx4 density at 2133 MT/s. Check the system documentation for maximum capacity per slot and total rank count per channel. Ensure the BIOS is current, as some platforms require a firmware update to recognise higher-density load-reduced modules.
The module installs into a standard 288-pin DDR4 DIMM socket and draws 1.20V from the memory bus. ECC and load-reduced buffering reduce electrical load on the memory controller, freeing rank budget for additional modules in the same channel. Identical modules can be added to scale capacity within the platform's supported configuration limits.
