Compatible Dell OptiPlex upgrade

This 16 GB DDR4 SO-DIMM is built for Dell OptiPlex 3070 Micro, 5070 Micro, 7070 Micro and 7470 All-in-One systems. It installs in a 260-pin slot and runs at 2666 MHz with CL19 timings at 1.2 V. The unbuffered, non-ECC module suits office and light-workstation workloads.

Single-module capacity increase

Each supported chassis offers two slots with a 32 GB ceiling, so this stick adds 16 GB in one slot and leaves the second free for a matching module. The jump is worthwhile when the factory 4 GB or 8 GB configuration limits multitasking or forces paging. Matched pairs enable dual-channel throughput for the best gain.

Steady throughput under load

The module uses major-brand chips rated for continuous 2666 MHz operation at standard voltage without a heat spreader. In the compact Micro and All-in-One enclosures, sustained workloads keep frequencies stable because the platform memory controller caps speed at the slowest installed module or CPU limit. Mixing speeds simply lowers the common rate.

Questions about this item

Will the 260-pin DDR4 SO-DIMM fit the single memory slot in a Dell OptiPlex 3070 Micro?

The module uses the standard 260-pin DDR4 SO-DIMM form factor required by the OptiPlex 3070 Micro, 5070 Micro, 7070 Micro and 7470 All-in-One, so it seats directly in the SO-DIMM slot without adapters.

What is the correct orientation step when installing this CL19 2666 MHz stick in a Dell OptiPlex 7070 Micro?

Align the notch on the 260-pin edge connector with the key in the slot, press firmly until the side clips click, then verify the system shows 16 GB at 2666 MHz in BIOS.

When should the 16 GB 2Rx8 unbuffered module be replaced if ECC errors appear on a Dell OptiPlex 7470 All-in-One?

The stick carries a lifetime warranty from Computer Memory Solutions; if memory diagnostics report uncorrectable errors, contact the manufacturer for a replacement under that warranty.
