utton (Red) 2.8 Untied Overclocking Technology This motherboard supports Untied Overclocing 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. 2.9 Serial ATA (SATA) Hard Disks Installation This motherboard adopts ULi M1573 southbridge chipset that supports Serial ATA (SATA) hard disks and RAID functions (RAID 0, 1, JBOD). You may install SATA hard disks on this motherboard for internal storage devices. This section will guide you to install the SATA hard disks. STEP 1: Install the SATA hard disks into the drive bays of your chassis. STEP 2: Connect the SATA power cable to the SATA hard disk. STEP 3: Connect one end of the SATA data cable to the motherboard's SATA connector. STEP 4: Connect the other end of the SATA data cable to the SATA hard disk. If you plan to use RAID 0, RAID 1, or JBOD functions on SATA, SATA HDDs must not operate in ATA Combination Mode enabled. Please refer to page 32 for details. 23
