Dell Optiplex 790 memory upgrade

This 4 GB DDR3 module is built for Dell Optiplex 790 MT, DT and SFF desktops. It uses a 240-pin DIMM form factor and runs at 1600 MHz with CL11 timing. The kit contains a single unbuffered, non-ECC stick.

Low-voltage DDR3 operation

The module runs at 1.5 V and has no heat spreader, keeping power draw modest in normal office workloads. Passive cooling is sufficient for typical desktop use. Noise and thermals remain at stock system levels.

Adds capacity to compatible Optiplex 790 systems

The platform supports up to 32 GB across four sockets, so this stick suits builds that need more multitasking headroom. It is not for systems that require ECC or registered memory. Buyers needing higher density per slot or faster speeds must look elsewhere.

Perguntas sobre este artigo

How do I install this 240-pin DDR3 DIMM in my Optiplex 790 and which step is often missed?

Align the notch on the module with the slot key, press firmly until both side clips click shut, then verify the BIOS shows the new 4GB at 1600 MHz.

What maintenance or replacement will this CL11 1.5V module need over time?

No scheduled maintenance is required; if a stick fails it is covered by the limited lifetime warranty from Computer Memory Solutions.

What limit appears first when this 1Rx8 unbuffered kit runs sustained workloads?

The system maximum of 32 GB across the four slots is reached before any thermal or voltage ceiling on this module.
