C.P.R. (CPU Parameter Recall)

The BIOS C.P.R. feature automatically restores the CPU default settings

when the system hangs due to overclocking failure. C.P.R. eliminates the

need to open the system chassis and clear the RTC data. Simply shut

down and reboot the system, and the BIOS automatically restores the

CPU parameters to their default settings.

ErP ready

The motherboard is European Union´s Energy-related Products (ErP)

ready, and ErP requires products to meet certain energy efciency

requirements in regards to energy consumptions. This is in line with

ASUS vision of creating environment-friendly and energy-efcient

products through product design and innovation to reduce carbon

footprint of the product and thus mitigate environmental impacts.
