Kingston Technology Corp. 64GB (2×32GB) DDR4 2666MHz SO-DIMM Desktop RAM CL19 with Anti-Static Wristband

Capacity and platform fit

This 64 GB kit supplies two 32 GB SO-DIMMs rated at 2666 MHz CL19 for Dell OptiPlex 3080, 5080 and 7080 micro form factor desktops. It is built as unbuffered DDR4 PC4-21300 memory and includes an anti-static wristband with grounding wire for safe handling. The modules use a 288-pin layout that matches the MFF motherboard slots.

Steady throughput under load

Unbuffered DDR4 at 2666 MHz delivers consistent bandwidth during extended workloads because there is no register stage to add latency. CL19 timing remains stable across long sessions, so compile jobs, database caches or virtual machines see predictable frame-to-frame access times. The SO-DIMM form factor fits the tight MFF chassis without blocking airflow to other components.

Straightforward slot-in install

Align the notch on each 288-pin SO-DIMM with the MFF socket key, press firmly until the side clips click, then attach the wristband clip to a grounded point before handling the modules. The only common mistake is attempting the upgrade in a small form factor or tower OptiPlex, which the kit explicitly does not support. No BIOS configuration is required; the system detects the new capacity on first boot.
