Dell OptiPlex 990 SFF Desktop

This Dell OptiPlex 990 is a Small Form Factor desktop computer built for everyday home and office tasks. It runs on an Intel Quad-Core i7-2600 processor clocked at 3.40 GHz with a 3.80 GHz Turbo Boost. The system includes 8 GB of DDR3 memory and a 1 TB 2.5-inch Solid State Drive. Windows 10 Pro 64-bit comes pre-installed for immediate use.

Suits general office and home users

The compact SFF chassis fits limited desk space while providing a DVD±RW drive and integrated Intel HD Graphics 2000 for standard display output. Gigabit Ethernet and a WiFi USB adapter handle network connectivity. Buyers who need discrete graphics performance for modern gaming or intensive 3D rendering should look elsewhere. The DDR3 memory standard also limits upgrade paths compared to newer platforms.

8 GB DDR3 memory capacity

The installed 8 GB of DDR3 RAM determines multitasking headroom for typical productivity applications. The manufacturer notes a maximum supported capacity of 16 GB using the same DDR3 DIMM 240-pin standard. This ceiling defines whether the system can handle heavier workloads or virtual machines. Verify your software requirements against this limit before purchasing.
