Transcend DDR4-2666 ECC DIMM 16GB

This Transcend module is a DDR4-2666 ECC DIMM with 16 GB capacity and a 2Rx8 organisation. It runs at 1.2 V and carries a CL19 latency rating. The stick uses Samsung DRAM and is built for commercial or industrial workloads that require error-correcting memory.

Upgrade from non-ECC or lower-capacity DDR4

The jump makes sense when your platform supports ECC and you need the 16 GB density for data-integrity tasks. It replaces standard unbuffered DIMMs that lack error correction or lower-density ECC sticks that limit total system memory. The 2666 MT/s speed matches common server and workstation memory buses.

Check motherboard ECC support and voltage tolerance

Verify that your board accepts 288-pin DDR4 ECC DIMMs and can run at 1.2 V. Confirm the CPU and chipset officially support ECC functionality, as some consumer platforms disable it. Ensure the 1.23-inch PCB height clears your CPU cooler. Note that warranty coverage may not apply outside Japan.

Questions about this item

Will the 1.23-inch PCB height clear my server chassis air baffle?

The module measures 1.23 inches tall, so verify the baffle gap in your chassis before ordering.

Which orientation notch on the 288-pin edge connector lines up with the DIMM slot key?

Align the single off-centre notch on the gold contacts with the slot key, press straight down until both retention clips click.

Does the Samsung DRAM require any firmware update or periodic re-training after installation?

No firmware or re-training is needed; the ECC DIMM runs at 2666 MT/s CL19 once seated and recognised by the BIOS.
