Dell OptiPlex 790 Mini Tower Desktop

This Dell OptiPlex 790 Mini Tower desktop is a complete system built around a second-generation Intel Core i5-2400 quad-core processor.

Perguntas sobre este artigo

How do I install the DDR3 memory modules and what step is often missed?

Align the notch on each 240-pin DDR3 module with the slot key, press down firmly until the retention clips snap shut, then verify the system recognises all 16 GB at boot.

Which component will likely need replacement first during the system's life?

The 3.5-inch 500 GB hard drive is the only moving part and typically fails before the solid-state components.

What thermal limit appears first when the i5-2400 runs at 3.10 GHz under sustained load?

The processor will hit its 3.40 GHz turbo ceiling and then throttle to stay within its thermal envelope.
