16GB DDR4 3200 module for Dell OptiPlex

This 16GB DDR4 3200 CL22 UDIMM is built for Dell OptiPlex 7080 SFF, 7080 Tower, 7090 SFF, 7090 Tower and XE4 SFF systems. It runs at 1.2V without ECC or buffering and fits the standard 288-pin desktop slot. The module is JEDEC compliant and RoHS certified for a warranty-safe upgrade.

Sustained multitasking with backward speed support

Under continuous workloads the memory maintains its 3200MHz rating at CL22 timing. It also operates at 2133MHz, 2400MHz, 2666MHz and 2933MHz when the platform requires a lower speed. The dual-rank 2Rx8 organisation helps keep throughput steady during long sessions with many applications open.

Replaces slower or smaller DDR4 DIMMs in listed

The upgrade is worthwhile when the installed modules run below 3200MHz or total capacity limits multitasking. It is not suited for systems that need ECC, registered memory or a different form factor. Buyers whose chassis only accept low-profile modules should verify clearance before ordering.

Questions about this item

How much power does the 1.2V DDR4 3200 module draw when the OptiPlex runs all day?

At the JEDEC-standard 1.2 V the 16 GB stick runs at the low voltage the platform expects, so sustained load adds only the normal DDR4 power envelope — no extra cooling or PSU headroom is needed.

What must the Dell OptiPlex already have for this 288-pin UDIMM to work?

A free 288-pin DDR4 slot on a 7080 SFF, 7080 Tower, 7090 SFF, 7090 Tower or XE4 SFF; the board must accept non-ECC unbuffered memory, which these models do.

Will the CL22 3200 MHz stick run with older 2133 MHz or 2400 MHz modules I keep in the same OptiPlex?

Yes — the module is backward-compatible down to 2133, 2400, 2666 and 2933 MHz, so it will clock down to match the slowest installed DIMM.
