Computer Memory Solutions CM5126412800DIMM 4GB DDR3 1600MHz for Dell Optiplex 7020 Mt/Sff memory upgrade

System-Specific DDR3 Upgrade

This 4 GB DDR3-1600 module is built for the Dell Optiplex 7020 MT and SFF desktops. It uses a 240-pin unbuffered DIMM with a CL11 timing profile. The stick is non-ECC and runs at the standard 1.5 V. Computer Memory Solutions validates each unit for these specific chassis.

DDR3-1600 Interface Limits

The DDR3-1600 standard tops out at 12 800 MB/s theoretical bandwidth. Four memory slots are available in the host system, capping total capacity at 16 GB. Single-channel operation applies when only one module is installed. Mixing speeds forces all sticks to run at the slowest common rate.

4 GB Capacity Headroom

A single 4 GB stick handles everyday office tasks and light multitasking comfortably. The Optiplex 7020 platform maxes out at 16 GB across four slots, so three more modules can be added later. Heavy workloads such as virtualisation or large datasets will exhaust this headroom quickly.
