Ultra Small Form Factor Desktop

The Dell OptiPlex 780 USFF is a compact desktop computer built around an Intel Core 2 Duo E8400 3.0 GHz dual-core processor. It ships with 4 GB of DDR3 RAM, a 250 GB hard drive and Microsoft Windows 7 Professional 64-bit pre-installed. Integrated Intel GMA 3000 graphics and a DVD-RW drive complete the basic configuration.

Installation and Common Issues

The ultra-small chassis limits internal access, so memory upgrades require low-profile DDR3 DIMM modules and storage changes use the Serial ATA interface. The proprietary layout can make cable routing awkward, and the legacy BIOS may not recognise drives larger than 2 TB without a firmware update.

Capacity and Headroom

The 250 GB hard drive holds the operating system, office documents and a modest media library, but fills quickly with modern applications or large photo collections. Four gigabytes of RAM handles single-task workflows, yet multitasking with several browser tabs or background updates pushes the system into heavy paging. The Intel Q45 chipset supports up to 16 GB of DDR3, giving a clear upgrade path when the stock memory becomes a bottleneck.

Questions about this item

How do I confirm the Intel Core 2 Duo E8400 is running at 3.0 GHz after setup?

Open Task Manager in Windows 7 Professional and check the Performance tab; the processor speed should read 3.0 GHz for the dual-core E8400.

What comes in the box and what must I buy separately for the OptiPlex 780 USFF?

The unit includes the desktop, power cord, 4 GB DDR3 RAM, 250 GB hard drive, DVD-RW drive, WiFi and Bluetooth adapters, and Windows 7 Professional pre-installed; you must buy a monitor, keyboard, and mouse separately.

Which memory version should I choose if I want to upgrade the 4 GB DDR3 later?

The system uses DDR3 DIMM 240-pin modules and supports up to 16 GB total; buy matching DDR3 240-pin sticks to add capacity.
