ASUS X99-A Motherboard

Other Features

The portrayed motherboard supports the installation of a TPM (Trusted Platform Module), in charge of storing encryption keys in order to increase the security of the computer.

This X99-A has a POST diagnostics display that shows through a two-digit code which component is preventing the computer from turning on. It also has power and reset buttons, as shown in Figure 7.

There is a “TPU switch” that enables an automatic overclocking, increasing the CPU clock multiplier (position “I”) or both the CPU clock multiplier and the CPU base clock (position “II”), and an “EPU switch” that enables or disables a power-saving feature. There are also one switch that configures the SLI or CrossFireX mode, and an “EZ_XMP switch,” which increases memory clock.

There is also a “MemOK!” button, which allows you to test the compatibility of the memory modules that are installed.

One curious fact is that the small heatsink near the rear panel has no function except aesthetics. As shown in Figure 8 (with the heatsink removed from its original place), the heatsink does not touch any component.
