32GB DDR4-2666 ECC Unbuffered DIMM

This 32GB DDR4-2666 module delivers error-correcting code memory for workstations and entry-level servers that require data integrity without registered buffering. It operates at 1.20V with a CL19 latency and a 2Rx8 rank organisation. The 288-pin DIMM uses unbuffered signal processing for direct memory controller access.

Check motherboard support for unbuffered ECC DDR4

Verify that your platform accepts unbuffered ECC DDR4 DIMMs at 2666 MHz and can supply 1.20V. Confirm the board has a free 288-pin slot and that the BIOS recognises 2Rx8 modules of this capacity. Intel XMP 2.0 profiles are present, but the system must be configured to apply them.

Sustained operation at rated speed and voltage

Under continuous load the module maintains 2666 MHz at 1.20V without a heat spreader, relying on chassis airflow for thermal management. ECC correction runs constantly to detect and fix single-bit errors during extended compute tasks. The unbuffered design keeps latency consistent across long sessions.

Questions about this item

Does the KTD-PE426E/32G module ship with any accessories or mounting hardware, or is it just the bare DIMM?

The KTD-PE426E/32G is supplied as a single 32GB 288-pin DDR4 DIMM without additional accessories or mounting hardware; it installs directly into a compatible motherboard slot.

Should I choose this 32GB CL19 2Rx8 module or a lower-capacity stick for my workstation?

Select this 32GB 2Rx8 module when you need maximum capacity per slot and ECC data integrity; choose a smaller kit only if your board limits total memory or you prefer lower density.

What does the 2666 MHz PC4-21300 rating mean for actual throughput in my server?

The 2666 MHz rating delivers up to 21300 MB/s peak bandwidth per module, with CL19 latency and 1.20V operation, provided the platform runs the memory at its rated DDR4-2666 speed.
