Using SATA / SATAII / SATA3 HDDs without NCQ function

STEP 1: Set Up UEFI.

A. Enter UEFI SETUP UTILITY Advanced screen Storage Configuration. B. Set the option “SATA Mode” to [IDE]. (For SATAII_0 to SATAII_3, SATA3_0 and

SATA3_1 ports.)

Set the option “ASMedia SATA3 Operation Mode” to [IDE]. (For SATA3_A0 port.)

STEP 2: Install Windows® 7 / 7 64-bit / VistaTM / VistaTM 64-bit OS on your system.

2.24 Untied Overclocking Technology

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 UEFI setup to set the selection from [Auto] to [Manual]. Therefore, CPU FSB is untied during overclocking, but PCI / PCIE buses are in the fixed mode so that FSB can operate under a more stable overclocking environment.

Please refer to the warning on page 9 for the possible overclocking risk before you apply Untied Overclocking Technology.
