The XPS 720 H2C Edition is built around a variety of premium technologies designed for overclocking. The system ships with 800MHz Corsair DOMINATOR EPP memory modules (factory overclocked to 1066MHz) combined with Intel multi-core processors (factory overclocked up to bin+3). Additionally, BIOS switches allow users to manipulate the speed of the front-side bus and chipset through the Windows operating system and third-party applications such as nVIDIA nTune.

To help ensure optimal operating conditions, Dell's patent-pending, two-stage liquid H2C Ceramic cooling technology can deliver optimized thermal controls with minimal power.

Dell has expanded the LightFX toolkit, originally introduced on the XPS M1710 notebook computer, to the XPS 720 H2C desktop. LightFX is a unique application that allows users and developers to manipulate the multi-colored perimeter lighting LEDs incorporated into the XPS 720 H2C Edition.
