Refurbished OptiPlex 755 desktop

This refurbished Dell OptiPlex 755 is a compact business desktop built around an Intel Core 2 Duo processor running at 2.33 GHz. It ships with 2 GB of memory and a 320 GB hard drive. Windows 10 Home is pre-installed, and a Microsoft Windows 11 Pro upgrade path is noted. The small form factor suits office environments where space is limited.

Included software and drive

The bundled Windows 10 Home licence provides a familiar desktop environment and the option to move to Windows 11 Pro when required. A combo optical drive handles CD and DVD media for legacy software installation or data archiving. Integrated Intel GMA 3100 graphics drive the video output without a separate card, keeping the 275 W power supply within its limits.

Chassis, connectivity and expansion

The black and silver chassis uses a slim layout with a 275 W supply and Gigabit Ethernet for wired networking. Four 240-pin DIMM slots are present, though all are currently populated with 512 MB modules totalling 2 GB. The Intel Q35 chipset and LGA 775 socket define the platform ceiling, while integrated audio covers basic sound needs without extra hardware.

Questions about this item

How much more memory can be added to the four DIMM 240-pin slots and what is the maximum supported?

All four slots are occupied by 512 MB modules, so adding memory requires replacing existing sticks; the board supports up to 8 GB total.

What component will hit its limit first during sustained loads with the 275 W power supply and integrated Intel GMA 3100 graphics?

The integrated Intel GMA 3100 graphics will reach its performance ceiling before the 275 W power supply becomes a bottleneck under sustained workloads.

How loud and hot does the system get when running all day with the Core 2 Duo 2.33 GHz processor and 275 W power supply?

The small-form-factor chassis uses a single fan that stays relatively quiet at idle but becomes noticeable under continuous load; the 2.33 GHz Core 2 Duo and 275 W supply keep internal temperatures within normal business-desktop ranges.
