Dell Optiplex 790 memory kit

This 4 GB kit contains two 2 GB DDR3 DIMMs built for Dell Optiplex 790 desktops. It targets owners of that model who need a straightforward capacity increase without guessing compatibility. The modules are unbuffered, non-ECC and run at the standard 1.5 V for the platform.

Two matched modules simplify installation

The pair is tested together so both sticks operate at the same 1333 MHz speed and CL9 timing. Buyers avoid mixing loose modules that can cause boot failures or down-clocking. The kit plugs directly into the four available slots and works within the system's 16 GB maximum.

DDR3 1333 MHz speed rating

The PC3 10600 specification decides whether this kit matches the board's memory controller. Systems requiring a different DDR generation or a higher data rate will not accept these modules. Check the motherboard manual for the supported speed before ordering.

Perguntas sobre este artigo

Will the 1.5 V DDR3 modules need any firmware updates or capacitor replacements over time?

No firmware or capacitor maintenance is required; the unbuffered 1.5 V DDR3 sticks run passively and have no serviceable parts.

What limit appears first when the Optiplex 790 runs all four DIMM slots at 1333 MHz continuously?

The platform caps total memory at 16 GB across four slots, so capacity is the first ceiling you reach.

How much heat and noise do the two 2 GB sticks add when the system runs all day without a heat spreader?

Bare 1.5 V DDR3 modules produce minimal heat and zero noise; case airflow handles the thermal load without extra cooling.
