64GB DDR4 UDIMM Bundle for Optiplex 3080, 5080, 7080

This kit provides 64GB of DDR4 memory across two 32GB unbuffered UDIMMs rated at 2666MHz CL19. It targets owners of Optiplex 3080, 5080 and 7080 small form factor and tower desktops who need the maximum supported capacity. An anti-static wristband with grounding wire is included for safe handling during installation.

DDR4 PC4-21300 speed and platform limits

The modules run at 2666MHz under the PC4-21300 specification with a CAS latency of 19. They are built as 288-pin UDIMMs for standard desktop slots and are explicitly not compatible with laptops or micro form factor computers. Buyers using other desktop platforms or smaller Optiplex chassis should verify support before purchasing.

Simple two-module install with static protection

Installation consists of seating both 32GB DIMMs into the available memory slots and wearing the supplied wristband to prevent electrostatic discharge. The kit contains no additional cables, brackets or software. The most common issue is attempting to fit these full-height UDIMMs into micro form factor systems where physical clearance prevents proper seating.

Questions about this item

Should I pick the 64GB (2 x 32GB) kit or a smaller capacity?

The 64GB (2 x 32GB) kit fills both slots on Optiplex 3080, 5080 and 7080 SFF and Tower desktops, giving the maximum dual-channel capacity those systems support.

What does the 2666MHz rating deliver in my Optiplex?

At 2666MHz the modules run at the native DDR4 speed the Optiplex 3080, 5080 and 7080 memory controllers are designed for, so you get the full rated bandwidth without down-clocking.

Does the PC4-21300 label limit what speed I actually see?

PC4-21300 is the JEDEC designation for 2666MHz DDR4, so the modules operate at that standard data rate when installed in compatible Optiplex desktops.
