16 GB DDR4-2666 ECC UDIMM

This 16 GB DDR4-2666 ECC UDIMM module is built for servers and workstations that require error-correcting memory without registered buffering. It suits administrators who need reliable capacity for virtualisation, database or file-serving workloads.

CL11 CAS latency and 1.20 V operation

The module runs at CL11 latency with a standard 1.20 V supply, delivering 2666 MT/s throughput under the PC4-21300 rating. These timing and voltage figures decide whether the DIMM matches the platform's memory controller requirements.

Fits 288-pin unbuffered ECC slots in dual-rank

Installation requires a motherboard with 288-pin DDR4 UDIMM slots that accept unbuffered ECC memory and support 2Rx8 organisation. The single module leaves remaining slots free for further capacity expansion up to the board's limit.

Perguntas sobre este artigo

What does the 2666 speed rating mean once the module is installed?

The module runs at 2666 MT/s with a CAS latency of 11, delivering a peak transfer rate of PC4 21300 in a system that supports DDR4 2666.

What interface does the 288-pin DDR4 connector use and what does it limit?

It uses a standard DDR4 SDRAM interface limited to 2666 MT/s and 1.2 V, so the module cannot exceed that speed or voltage.

What physical slot and clearance does this 288-pin UDIMM need?

It fits a standard 288-pin DDR4 UDIMM slot and requires the usual DIMM height clearance for an unbuffered module.
