4GB DDR3 1600MHz DIMM for Dell Optiplex 3020

This 4GB DDR3 memory module is built specifically for the Dell Optiplex 3020 MT and SFF desktop systems. It installs directly into a 240-pin DIMM slot and runs at 1600MHz with CL11 timing. The unbuffered, non-ECC design matches the original system requirements for a straightforward capacity increase.

Ideal for Optiplex 3020 owners adding a single

This upgrade suits users whose Dell Optiplex 3020 has a free DIMM slot and supports the stated 16GB maximum across two sockets. It is not for systems that require ECC or registered memory. Builders working on any other desktop or laptop model cannot use this module because the compatibility guarantee applies only to the listed Optiplex 3020 MT and SFF platforms.

1600MHz DDR3 speed with CL11 latency

The module operates at PC3-12800 speed with a CAS latency of 11 and a 1.5V voltage. This specific speed and timing combination determines whether the memory will run correctly in the target system. Verify that your Optiplex 3020 configuration accepts DDR3 1600MHz non-ECC DIMMs before ordering.

Questions about this item

Does my Dell Optiplex 3020 Mt/Sff need an open 240-pin DDR3 slot for this module?

Yes, the CM5126412800DIMM uses the 240-pin DDR3 form factor and fits a free DIMM socket in the Optiplex 3020 Mt/Sff.

Can I keep my existing DDR3 1600 CL11 memory and add this 4 GB stick?

The module runs at 1600 MHz with 11-11-11 timing at 1.5 V, so it will match other DDR3 1600 CL11 sticks already installed.

How do I verify the new RAM is running at 1600 MHz after installation?

Check the memory speed in the BIOS or with a tool like CPU-Z; it should report 1600 MHz (PC3-12800) for the CM5126412800DIMM.
