Server memory for registered ECC platforms

This Kingston module delivers 32GB of DDR4 capacity at 3200 MT/s with a registered signal and ECC support. It is built for servers and workstations that require error correction and buffered addressing for stable operation under sustained workloads.

Registered DIMM with 288-pin DDR4 interface

The registered design places a register between the DRAM and the memory controller, reducing electrical load on the motherboard and allowing larger memory populations per channel. The 288-pin DDR4 form factor fits standard server DIMM slots and operates at 1.20V for efficient power use.

Single-rank 1Rx4 organisation with CL22 timing

The single-rank 1Rx4 layout provides straightforward timing at CL22-22-22, simplifying memory training and compatibility on qualified platforms. No additional accessories or software are bundled; the module itself is the complete product for direct installation.
