Two green SO-DIMM sticks and a blue anti-static wristband

Kingston Technology Corp.

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

SKU CH-W57T-0VED8

A 64GB DDR4 2666MHz SO-DIMM kit with CL19 latency and an anti-static wristband, built for Optiplex 3080, 5080 and 7080 micro desktops

  • 64GB total capacity from two 32GB modules for heavy multitasking
  • 2666MHz DDR4 speed rated at PC4-21300 for responsive performance
  • CL19 CAS latency keeps timing tight under load
  • SO-DIMM form factor fits Optiplex 3080, 5080 and 7080 MFF desktops
  • Anti-static wristband with grounding wire protects components during installation

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.

Questions about this item

How much power does the 64GB DDR4 2666MHz kit draw when the Optiplex 3080 runs all day?

Standard DDR4 SO-DIMMs at 2666 MHz typically consume a few watts per module under load, so the pair adds only a small amount to the system’s total power draw and produces minimal extra heat inside the Micro Form Factor chassis.

What must the desktop already have for these two 32GB SO-DIMMs to work?

The PC must be an Optiplex 3080, 5080 or 7080 Micro Form Factor with two free SO-DIMM slots that accept 288-pin DDR4 PC4-21300 unbuffered non-ECC memory.

Will the CL19 modules run correctly alongside any original 2666MHz sticks I keep in the Optiplex 7080 MFF?

Yes, the memory controller will operate all installed modules at the common 2666 MHz speed and CL19 timing, so older compatible sticks can remain in place without stability issues.
