Kingston Technology Corp. KSM26RD4/32HDI 32GB DDR4 2666 CL19 ECC Registered server RAM

32GB DDR4-2666 Registered ECC Module

This 32GB DDR4 module runs at 2666MHz with CL19 timings and 1.20V operation. It features ECC parity checking and registered signal processing for data integrity. The 288-pin DIMM uses a 2Rx4 rank configuration without a heat spreader. It is built for server platforms that require registered memory.

Registered DIMMs Require Platform Support

Registered memory modules place a register between the DRAM and the memory controller to reduce electrical load. This design only functions on motherboards with chipsets and BIOS firmware that explicitly support registered DIMMs. Standard desktop and consumer workstation boards typically cannot initialise these modules. The DDR4-2666 speed rating follows the PC4-21300 standard for bandwidth specification.

Verify Registered Memory Compatibility First

Before ordering, confirm your server motherboard qualification list includes registered ECC DDR4 DIMMs at this density and speed. Check that the memory controller supports 2Rx4 rank organisation for 32GB modules. Ensure the system BIOS is updated to a version that validates this configuration. Systems requiring unbuffered or non-ECC memory will not operate with this module.
