32GB DDR4 2666 ECC UDIMM for servers

This 32GB DDR4 2666 ECC UDIMM module is built for server and workstation systems that require error-correcting memory. It operates at 1.20V with CL19 latency and uses a 2Rx8 rank configuration. The unbuffered design suits platforms that accept ECC UDIMMs rather than registered DIMMs.

Check DDR4 288-pin ECC UDIMM support

Verify that your motherboard accepts DDR4 288-pin ECC UDIMM modules and supports 2666MHz operation at 1.20V. Confirm the maximum capacity per slot and total system limit before ordering. This module replaces Kingston KSM26ED8/32HA, KSM26ED8/32ME and KTD-PE426E/32G part numbers.

Fits single-slot upgrades in compatible platforms

The single 32GB module fills one DIMM slot and leaves remaining slots free for further expansion. ECC functionality protects data integrity in critical workloads while the standard DDR4 voltage keeps power draw predictable. Ensure your BIOS recognises the 2Rx8 organisation for proper operation.

Questions about this item

Does the 32GB DDR4 2666 ECC UDIMM come as a single 288-pin module or do I need to buy additional sticks?

The product is a single 32GB module in a 288-pin DIMM form factor; no extra sticks are included.

When would I choose this 32GB 2Rx8 CL19 module over a lower-capacity or single-rank alternative?

Choose this 32GB 2Rx8 CL19 module when your server or workstation requires maximum capacity per slot and supports ECC unbuffered DDR4 at 2666 MHz.

What does the PC4-21300 rating tell me about real-world throughput?

PC4-21300 is the JEDEC designation for DDR4 2666; the module runs at 2666 MT/s with CL19 latency at 1.20V when installed in a compatible system.
