16GB DDR4 ECC UDIMM for Lenovo Servers

This 16GB DDR4 module runs at 2666MHz with CL19 latency and 1.2V operation. It uses an unbuffered ECC design built with major-brand chips in a 2Rx8 configuration. The 288-pin DIMM fits compatible Lenovo servers and workstations that accept the 01KR360 part number.

DDR4 2666 unbuffered ECC limits

Unbuffered ECC DIMMs operate without a register between the memory controller and the DRAM chips. This design reduces latency but restricts the maximum module count per channel compared to registered alternatives. Systems must support ECC UDIMM topology and DDR4 2666 signalling to use this module at its rated PC4-21300 bandwidth.

288-pin build and daily handling

The module uses a standard 288-pin DDR4 DIMM edge connector with gold contacts that resist oxidation during repeated seating. Major-brand chips are screened through quality-assurance testing before shipment. The single-module packaging simplifies upgrades for administrators who need to populate one slot at a time without splitting kits.

Questions about this item

Should I choose the 1x 16GB module or a 2x 8GB kit for my server?

This listing supplies a single 16GB DDR4 2666 ECC UDIMM module. If your server has free DIMM slots you can add it alone; for dual-channel bandwidth you would need a second identical 16GB stick.

What does the 2666 MHz rating actually deliver once the module is installed?

The module runs at DDR4 2666 (PC4-21300) with CL19 latency at 1.2V, providing the rated throughput when the platform memory controller is set to that speed.

Is this a registered DIMM or an unbuffered ECC UDIMM, and what does that limit?

It is an ECC UDIMM (unbuffered), so it works in platforms that accept unbuffered ECC memory and cannot be mixed with registered RDIMMs.
