Targeted upgrade for Dell OptiPlex 9020 systems

This OWC module adds 4GB of DDR3 memory to OptiPlex 9020 Micro, SFF, Tower and USFF desktops. It is built for owners of those specific models who want a straightforward capacity increase without configuration hassles. The kit is not for builders working on other platforms or for anyone needing ECC error correction.

DDR3 1600 PC3-12800 CL11 specification

The single decisive figure is the DDR3 1600 PC3-12800 CL11 rating; the OptiPlex 9020 chipset requires this exact speed and latency combination. A different DDR generation will not fit the 240-pin slots and a different speed grade can prevent the system from posting. The module runs at the standard 1.5V JEDEC voltage.

4GB capacity for everyday multitasking

A single 4GB DIMM lets the machine keep more browser tabs, office documents and background services in memory at once. It handles typical productivity workloads comfortably but runs out when editing large media files or running virtual machines alongside heavy applications. Adding a second identical module would double the headroom if the board has a free slot.
