8GB DDR3 1600 Module for Dell Optiplex 3020

This 8GB DDR3 1600 memory module is built specifically for the Dell Optiplex 3020 MT and SFF systems. It uses a 240-pin DIMM form factor and operates at 1.5V with CL11 latency. The single stick provides a straightforward capacity increase for compatible desktops.

Suits owners upgrading a Dell Optiplex 3020.

This module targets users who need more RAM in a Dell Optiplex 3020 MT or SFF chassis. It will not fit laptops, servers or motherboards requiring ECC, registered, SODIMM or a different DDR generation. Buyers with a different desktop model should verify their exact specifications first.

Simple DIMM installation; watch for slot limits

Installation follows the standard desktop DIMM process: power down, open the case and press the module into the 240-pin slot until the clips lock. The Optiplex 3020 has two slots and a 16GB maximum, so a second 8GB stick fills the board. Mismatched speeds or exceeding the slot count will prevent the system from booting.

Questions about this item

Does the Dell OptiPlex 3020 MT/SFF need a free 240-pin DDR3 slot to install this 8GB module?

Yes, the system uses 240-pin DDR3 DIMM slots and this stick occupies one of them.

Can I keep my existing 1600 MHz DDR3 memory and add this CL11 8GB stick alongside it?

It will run at the speed and timings of the slowest installed module, so matching 1600 MHz CL11 memory works best.

How can I confirm the new memory is detected at 1600 MHz after installation?

Check the BIOS memory information or Windows Task Manager — both should show 8GB running at 1600 MHz.
