Intel DX58SO2/DX58OG Desktop Board Performance Tuning Guide

3.4.4 Remove Power and Reboot

For a system hang, resetting your system or removing, reapplying AC power, and

rebooting will allow the system to initiate a reboot. Note that BIOS settings will

remain unchanged during a reset or removal of AC power. The watchdog timer, the

Back to BIOS button, the BIOS configuration jumper, or pressing the F2 key at the

setup screen prompt will allow the user to adjust performance settings in BIOS to

restore system stability.

Performance Tuning Process

Simplified tuning processes for use with either Intel Extreme Edition or non-Extreme

Edition processors are included below. The simplified tuning process allows users to

make a significant increase in performance in a few easy steps. More in depth tuning

procedures are included in Section 3.5.3 of this guide for users wanting to increase

performance levels beyond those obtained with the simplified tuning processes.

3.5.1 Simplified Tuning Process for Intel

Core™ i7

Extreme Edition Processors

These performance settings are applicable with the Intel Core i7 Extreme Edition

processors. This includes the Intel Core i7-990X, i7-980X, i7-975, and i7-965

processors. An Intel tower model E88216-001 fan heatsink was used for processor

cooling with the performance settings listed below.

Performance Settings

1. Power up the system and press the F2 key to go into BIOS setup mode.

2. These instructions assume default BIOS settings are present and only changes

from those defaults are listed below. Optionally, the F9 key may be pressed to

load Setup Defaults. If other BIOS configuration changes have been previously

made (i.e., SATA Configuration), they will need to be reapplied after loading Setup

Defaults.

3. From the BIOS Performance menu where the disclaimer asks if you wish to

continue, select Yes. This will enable the Performance screen to be displayed.

4. Scroll down and select the Processor submenu. From the Processor Overrides

screen, make the following settings:

a. Set the Processor Voltage Override Type to Dynamic.

b. Set the Dynamic Processor reference Voltage to 1.3500 volts.

c. Set TDC current limit override to 200 amps.

d. Set TDP Power Limit Override 150 watts.

e. Set core ratio limits (also referred to as multipliers or Turbo ratios) to 31 for

each processor core.
