4GB DDR3 Kit for OptiPlex 990

This 4GB kit contains two 2GB DDR3 modules built to match the Dell OptiPlex 990 desktop, mini-tower and small-form-factor systems. The memory runs at 1333MHz with CL9 timing and operates at the standard 1.5V. It is unbuffered, non-ECC and uses a 240-pin DIMM form factor.

Suits OptiPlex 990 owners adding memory

The kit fits the OptiPlex 990 DT, MT and SFF chassis as well as the Ultra by MS variant. It will not work in systems that require ECC, registered modules or a different DDR generation. Buyers needing more than 4GB total capacity or a higher speed grade should look at other options.

1333MHz DDR3 speed confirms fit

The rated speed of DDR3 1333 (PC3 10600) is the single specification that determines whether this kit matches the OptiPlex 990 memory controller. Verify that your system specifies this exact speed before ordering.
