Untied Overclocking Technology

echnology

This motherboard supports Untied Overclocking Technology, which means during
overclocking, FSB enjoys better margin due to fixed PCI / PCIE buses. Before you
enable Untied Overclocking function, please enter “Overclock Mode” option of
BIOS setup to set the selection from [Auto] to [CPU, PCIE, Async.]. Therefore, CPU
FSB is untied during overclocking, but PCI and PCIE buses are in the fixed mode so
that FSB can operate under a more stable overclocking environment.

HDMR Card Driver Installation

When you install the drivers to your system, please make sure to install Realtek
Audio driver before installing HDMR card driver; for other drivers installation,
please follow the driver order in our support CD. It is suggested to install Win-
dows

OS, Realtek Audio and HDMR drivers with the HDMR card inserted to this

motherboard; in this way, there is no problem on the Audio CODEC function.
However, if you install Windows

XP 64-bit OS without HDMR card inserted and

plan to insert the HDMR card to this motherboard, please install the Realtek Audio
driver again; otherwise, the Audio CODEC will not work. If you install Windows

2000 / XP OS without HDMR card inserted and plan to insert the HDMR card to this
motherboard, you just have to restart your computer, then the Audio CODEC can
work successfully.
