System-specific DDR3 kit for Dell Optiplex 9020

This 8 GB kit contains two 4 GB DIMMs rated at 1600 MHz with CL11 timings and 1.5 V operation. The modules are unbuffered, non-ECC and built on a 240-pin DDR3 interface. Computer Memory Solutions validates compatibility for the Optiplex 9020 MT, SFF and USFF form factors.

Suits owners restoring

The kit matches the factory specification for these desktops and fills two of the four available slots. Buyers needing more than 32 GB total capacity or registered ECC modules should look elsewhere. Systems that require a different pin count, voltage or DDR generation will not accept these sticks.

The 240-pin DDR3 1600 MHz CL11 specification

Only motherboards designed for unbuffered non-ECC DDR3 at 1.5 V can use this memory. The 1Rx8 rank organisation and 11-11-11 timing are fixed by the module design. Verify the target system uses 240-pin DDR3 slots before ordering.

Questions about this item

My Optiplex 9020 has four DIMM slots — will this 2 x 4 GB kit leave room to reach the 32 GB maximum?

Yes, the kit occupies two of the four slots so you can add two more modules later to reach the 32 GB limit.

The modules are specified as 1.5 V unbuffered non-ECC — does that match the Optiplex 9020 MT/SFF/USFF memory requirements?

The kit is built to the 1.5 V unbuffered non-ECC DIMM standard that the Optiplex 9020 MT/SFF/USFF uses.

After installing both sticks, how can I confirm the system sees the full 8 GB at 1600 MHz CL11?

Check the BIOS memory information or the operating-system task manager; they should report 8 GB total running at 1600 MHz with CL11 timings.
