Dell OptiPlex 990 SFF Desktop

The Dell OptiPlex 990 SFF is a small form factor desktop computer powered by an Intel Quad-Core i7-2600 processor running at 3.40GHz with a 3.80GHz turbo boost. It comes with 16GB of DDR3 memory and a 256GB 2.5" solid state drive. Windows 10 Pro 64-bit is pre-installed along with a DVD±RW drive, USB keyboard and mouse.

DDR3 Memory and SFF Constraints

This system uses 240-pin DDR3 desktop memory modules; no other DDR generation is compatible. The small form factor case limits internal expansion space and restricts the use of full-height add-in cards. Integrated Intel HD Graphics 2000 provides basic video output without support for discrete graphics upgrades.

16GB DDR3 Decides Fit

The installed 16GB of DDR3 RAM represents the maximum memory capacity for this configuration. Buyers who need more memory must choose a different platform because the chipset and form factor prevent further upgrades. This specification determines whether the system meets your multitasking requirements.

Questions about this item

Should I pick the 16 GB DDR3 configuration or add more later?

This unit already ships with 16 GB of DDR3 memory installed. The motherboard uses 240-pin DIMM slots and DDR3 is the only supported generation. If you need more capacity you would have to replace existing modules with higher-density DDR3 sticks; no other memory type fits.

What does the 3.40 GHz quad-core i7-2600 deliver in daily use?

The Intel Core i7-2600 runs at a base clock of 3.40 GHz and can boost to 3.80 GHz on up to four cores. With 8 threads it handles typical office multitasking, web browsing and media playback smoothly. The integrated Intel HD Graphics 2000 drives basic display output but is not suited for modern 3D gaming.

Which video outputs does the SFF case provide for a monitor?

The small form factor chassis relies on the integrated Intel HD Graphics 2000 for video. Available ports are those native to the OptiPlex 990 SFF rear I/O panel — typically VGA and DisplayPort — allowing direct connection of one or two monitors without a discrete graphics card.
