32GB DDR4 ECC DIMM

This Kingston KTL-TS426E/32G module delivers 32GB of DDR4 2666 memory with ECC error correction for rack-server workloads. The unbuffered 2Rx8 design targets systems that require registered-free signalling while maintaining data integrity. It suits administrators who need single-module capacity upgrades without moving to registered memory.

Unbuffered 288-pin build

The standard 288-pin DIMM fits DDR4 server slots that accept unbuffered ECC modules and operates at 1.20V. Dual-rank organisation provides density within a single slot, leaving additional slots free for further expansion. Buyers whose platforms mandate registered or load-reduced DIMMs cannot use this module.

Module-only supply

The package contains the memory stick alone; no software, heat spreader or mounting hardware is bundled. Configuration relies entirely on the host system BIOS to apply the CL19 timings and 2666 MT/s speed. Administrators needing pre-tested kits or labelled multi-module sets must source them separately.

Questions about this item

What data rate does DDR4-2666 cap at in practice?

The module runs at 2666 MT/s, which is the maximum speed the DDR4-2666 standard defines for this part.

What slot and clearance does the 288-pin DIMM require?

It fits a standard DDR4 288-pin DIMM socket and needs the usual DIMM height clearance inside a rack server chassis.

How is the ECC unbuffered module installed and what step is often missed?

Align the notch with the key, press firmly until both retention clips click, then verify the BIOS recognises 32 GB at 2666 MT/s with ECC active.
