Computer motherboards and expansion cards contain very delicate Integrated Circuit (IC) chips. To avoid damaging them due to static electricity, follow these precautions whenever you work on your computer. 1. Unplug the computer when working on the internal components. 2. Use a grounded wrist strap or touch a safely grounded object or to a m

It is recommended to use CPU Default as the CPU core voltage. CPU Default means the Vcore is generated according to the CPU VID configuration. For each jumper setting, there are two voltage options, depending on the CPU used.

HARDWARE SETUP 6) USB Device Wake-up (USB01PWR / USB23PWR / USB45PWR) Set these jumpers to +5V to allow wake up from the S1 sleep state (CPU stopped; RAM refreshed; system running in low power mode). The default setting for the three jumpers is [1-2] to select +5V, since not all computers have the appropriate power supply. NOTE: This feature requires an ATX power supply that can supply at least 2A on the +5VSB lead when these jumpers are set to +5VSB. Othe
