Dell OptiPlex 990 SFF All-in-One 22

This Dell OptiPlex 990 SFF All-in-One integrates a 22-inch 1920 x 1080 display with a compact desktop base. It runs on a 2nd Gen Intel Core i5-2400 processor at 3.10 GHz with 16 GB of DDR3 RAM and a 256 GB solid-state drive. Windows 10 Pro 64-bit is pre-installed. A USB keyboard, mouse and USB Wi-Fi adapter are included for immediate setup.

Thermals noise and power in normal use

The small form factor chassis houses the processor, memory, storage and optical drive behind the screen. Office workloads such as document editing, web browsing and video playback run within the thermal envelope of the integrated cooling solution. The DVD-RW drive spins only when media is accessed, keeping acoustic output low during typical productivity tasks.

Upgrade path and when the jump matters

This system replaces a tower-and-monitor combination where desk space is limited and cable count must be minimal. The 256 GB SSD and 16 GB DDR3 allocation cover multi-tab browsing and light content creation without storage swaps. Buyers who need discrete graphics performance, additional internal drive bays or newer memory standards should consider a separate tower platform.

Questions about this item

How do I install the 16 GB DDR3 memory in this small-form-factor OptiPlex 990, and what step is often missed?

Open the SFF chassis, insert each DDR3 module into a DIMM slot until the retention clips click, then reinstall the fan shroud so airflow reaches the memory area.

What maintenance or replacement will the 256 GB 2.5-inch SSD and DVD-RW drive need later?

The SSD has no moving parts and needs no routine service; the DVD-RW may eventually require a laser-lens clean or drive swap if disc errors appear.

Which limit appears first when the i5-2400 runs at sustained load inside this all-in-one base?

The compact AIO thermal solution saturates first, so the CPU throttles from its 3.60 GHz turbo ceiling to protect itself.
