VID[4:0] Pins | The VID[4:0] (Voltage Identification) outputs are used to | |||||
| dictate the VCC_CORE voltage level. The VID[4:0] pins are | |||||
| strapped to ground or left unconnected on the processor | |||||
| package. The VID[4:0] pins are pulled up on the motherboard | |||||
| and used by the VCC_CORE DC/DC converter. | |||||
| The VID codes and corresponding voltage levels are shown in | |||||
| Table 23. |

VREFSYS Pin | VREFSYS (W5) drives the threshold voltage for the system bus | |||||
| input receivers. The value of VREFSYS is system specific. In |
addition, to minimize VCC_CORE noise rejection from VREFSYS, include decoupling capacitors. For more information, see the AMD Athlon™
