QNAP 4GB DDR4 2666 SO-DIMM

This QNAP module provides 4GB of DDR4 memory in a 260-pin SO-DIMM form factor rated at 2666 MT/s (PC4 21300). It is built for compatible QNAP NAS appliances and laptops that accept DDR4 SO-DIMMs. The T1 version designation identifies this specific part number for ordering accuracy.

Suits DDR4 SO-DIMM slots at 2666 MT/s

This module suits administrators upgrading a supported QNAP system or laptop with an available 260-pin DDR4 slot running at 2666 MT/s. It does not suit systems that require DIMM form factors, different pin counts, other DDR generations, or speeds not matching the PC4 21300 rating.

Deciding spec: 260-pin DDR4 SO-DIMM at 2666 MT/s

The single specification that decides fitment is the 260-pin DDR4 SO-DIMM interface operating at 2666 MT/s (PC4 21300). Verify that the target device explicitly supports this exact pin layout, generation, and speed before purchase.
