Power Bios Features - Nvidia nForce4 Ultra Manual Del Usuario

Introduction

3-4 POWER BIOS Features

This page lets you adjust various parameters to obtain improved performance for overclocking.
Overclocking requires expert knowledge and risks permanent damage to system components.
We recommend you leave these parameters at their default values for proper operation.
CPU Frequency
Enables you to increment the CPU's clock generator at 1 MHz step. This works together with CPU Clock Ratio (below)
to set the CPU operating frequency.
CPU Clock Generator x CPU Clock Ratio = CPU Frequency
For example, if you have a processor that is rated at 2.4GHz and the clock generator is 200MHz, then 200MHz x 12
= 2.4GHz
Options: 200 to 450 in 1MHz increments.
Overclocking failure will cause no display on the monitor. To overcome this switch off the power supply
and switch on again. Restart the system, press and hold < Insert> key. This will revert the BIOS to
default or initial setting.
PCIE Clock
Enables you to subtle tune the PCI-E frequency at increments of 1MHz step.
Options: 100 to 145 in 1MHz increments.
CPU Clock Ratio
Use this item to select a multiplier to set the CPU frequency. See CPU Frequency item above for explanation. If your CPU
multiplier is locked this option will be unavailable.
AMD K8 Cool'n'Quiet
Reduce the noise and heat from your PC when AMD's Cool'n'Quiet
Options: Auto, Disabled.
CPU Voltage
This item allows you to adjust the CPU Vcore voltage.
Options: Off, Auto, -0.200V to +0.350V in 0.025V increments. We recommend that you leave this at the default
value.
Chipset Voltage
This item allows you to adjust the Chipset voltage.
Options: +1.5V to +1.8V in 0.1V increments. We recommend that you leave this at the default value.
