Direct Dell OptiPlex 790 Upgrade

This 2GB DDR3-1333 module is built specifically for Dell OptiPlex 790 desktops. It installs in any of the four 240-pin DIMM slots and runs at 1.5V without requiring ECC or registered buffering. The single stick delivers PC3-10600 bandwidth at CL9 timing.

Suits owners adding capacity to a 790

Buyers who need ECC error correction, registered signal buffering, or speeds beyond DDR3-1333 should look at something else. The unbuffered, non-ECC design matches the desktop platform exactly, but it will not satisfy server or workstation requirements that demand those features.

2GB capacity per module

Each stick provides 2GB of memory, and the system accepts up to 16GB total across its four slots. Populating all banks with identical modules reaches that ceiling, while mixing lower-density sticks limits the final amount.

Questions about this item

Will the 16 GB maximum capacity of the Dell OptiPlex 790 limit this 2 GB DDR3-1333 module under sustained use?

The OptiPlex 790 supports up to 16 GB across four slots, so a single 2 GB module leaves ample headroom before the platform limit becomes a constraint.

How much heat or power does this unbuffered non-ECC DDR3 stick generate when running all day at 1.5 V?

As a standard 1.5 V DDR3 DIMM without a heat spreader, it draws typical low power for its class and runs cool enough for continuous operation inside the OptiPlex 790 chassis.

Does my OptiPlex 790 need a specific BIOS revision or chipset to recognise this 240-pin DDR3-10600 module?

The module is validated for the OptiPlex 790 platform; installing it in any of the four 240-pin slots will be recognised without additional hardware.
