Dell Optiplex 390 Memory Kit

This 8GB kit uses two 4GB DDR3 DIMMs built for the Dell Optiplex 390. The modules run at 1333MHz with CL9 timing at 1.5V. They are unbuffered, non-ECC and use a 240-pin layout. The pack contains two sticks ready to install.

Suits Optiplex 390 owners adding standard memory

Buyers who need ECC error correction cannot use this kit. Systems requiring registered or buffered modules should look elsewhere. Machines limited to lower voltage memory are not supported. The kit only works with 240-pin DDR3 slots.

240-pin DDR3 form factor decides fit

The modules use the 240-pin DDR3 interface that the Optiplex 390 expects. A different pin count or DDR generation will not seat in the board. Confirm the slot type before ordering. This spec alone determines whether the upgrade works.
