Refurbished OptiPlex 745 business desktop

This Dell OptiPlex 745 (NE1-0031) is a refurbished tower system built for office environments. It runs a 2.13 GHz Intel Core 2 Duo processor with 2 MB L2 cache on an Intel Q65 chipset. The unit ships with 4 GB of memory installed across four DIMM slots and a 750 GB hard drive. Integrated Intel GMA 3100 graphics, Gigabit Ethernet and a DVD drive complete the configuration. Windows 10 Home is pre-installed.

Suits basic office tasks; not for modern workloads

The dual-core 64-bit processor and integrated graphics handle document editing, email and legacy business applications. Buyers who need more memory will find all four slots occupied, leaving no room for expansion without removing existing modules. The 305 W power supply and integrated graphics make this unsuitable for gaming, video editing or CAD work. Organisations requiring Windows 11 out of the box should note the system ships with Windows 10 Home.

LGA 775 socket limits processor upgrades

The motherboard uses an LGA 775 socket with a 1066 MHz front-side bus and supports a single CPU. This socket generation restricts upgrades to older Core 2 Duo or compatible processors only. No newer Intel or AMD CPUs will fit this platform. The four 240-pin DIMM slots are fully populated at 1 GB each, so any memory increase requires replacing the existing sticks.

Questions about this item

What tower dimensions and 305W power supply clearance does the OptiPlex 745 NE1-0031 require?

The unit is a standard black/silver tower chassis that houses a 305W power supply; allow enough depth and rear clearance for the PSU fan and cable routing.

How do I install additional memory in the four 240-pin DIMM slots when all slots are currently populated with 1GB modules?

All four slots hold 1GB modules for the 4GB total; to add capacity you must remove existing sticks, match the 240-pin form factor, and refill slots in matched pairs.

When will the LGA 775 Core 2 Duo processor or the 750GB hard drive likely need replacement?

The LGA 775 socket limits CPU upgrades to similar-era chips, and the mechanical 750GB drive should be monitored for SMART warnings and replaced if noise or errors appear.
