Capacity and Compatibility

This 32GB DDR4 SODIMM module is built for Dell OptiPlex 7480, 7490 and 7780 all-in-one systems. It suits professionals who need more memory for multitasking and larger datasets in those specific AIO workstations. Buyers with other Dell models or non-AIO desktops cannot use this module.

Speed, Latency and Headroom

The stick runs at 3200MHz with PC4-25600 bandwidth and CL22 latency at 1.2V. It handles everyday office workloads, browser-heavy sessions and light content creation comfortably. Workloads that demand ECC protection, registered buffering or speeds beyond the JEDEC DDR4 3200 standard will exceed this module's capabilities.

Installation and Build Fit

The 260-pin unbuffered non-ECC SODIMM plugs directly into the SO-DIMM slot inside the OptiPlex AIO chassis. No heat spreader is fitted, so clearance is minimal and airflow is unaffected. Systems that require ECC, registered DIMMs or a different pin count will not accept this upgrade.

Questions about this item

Will the 32GB DDR4 3200 CL22 SODIMM run with the existing memory already inside my OptiPlex 7480 AIO?

The module is 1.2V DDR4 3200 CL22 260-pin non-ECC unbuffered 2Rx8; matching those specs with the installed sticks avoids timing mismatches.

How can I confirm the 32GB DDR4 3200 CL22 SODIMM is operating correctly after installing it in my OptiPlex 7490 AIO?

Boot into BIOS or UEFI and verify the new module shows 32GB at 3200 MT/s with CL22 latency and 1.2V.

What comes in the box with the 32GB DDR4 3200 CL22 SODIMM and is anything else required for my OptiPlex 7780 AIO upgrade?

Only the single 32GB 260-pin SODIMM is included; no tools or extra parts are needed for the AIO slot.
