OptiPlex 755 business desktop

The DELL OptiPlex 755 is a refurbished small-form-factor desktop aimed at office environments that need a compact, quiet system for everyday productivity. It runs an Intel Core 2 Duo processor at 2.66 GHz 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 integrated Intel GMA 3100 graphics and Gigabit Ethernet handle typical business workloads.

Who this suits and who it does not

This unit fits buyers who want a ready-to-use Windows 10 PC for document editing, email and legacy line-of-business applications. It is not for users who need discrete graphics performance, modern gaming capability or more than the installed 2 GB of memory without sourcing compatible modules separately. The four DIMM slots are already populated, so any memory increase requires replacing the existing sticks. The 275 W power supply and small chassis also rule out most add-in cards that need supplementary power.

Deciding specification: installed memory

The critical detail is that 2 GB is installed across four occupied 240-pin DIMM slots in a 512 MB × 4 arrangement, leaving zero free slots for simple expansion. If the intended workload runs acceptably in 2 GB this desktop is a match; if more memory is required the buyer must plan a full module replacement rather than an upgrade.

Questions about this item

What form factor and slot type does the memory use?

The system uses 240-pin DIMM modules installed in four slots, all currently occupied by 512 MB sticks.

How is the processor mounted and what is a common installation error?

The Core 2 Duo seats in an LGA 775 socket; a frequent mistake is bending socket pins by forcing the CPU without aligning the notches.

What component will likely need replacement first and what are the limits?

The 275 W power supply is the usual first failure point; the board supports a maximum of one LGA 775 processor.
