[. . . ] After you install the CPU into this motherboard, it is necessary to install a larger heatsink and cooling fan to dissipate heat. You also need to spray thermal grease between the CPU and the heatsink to improve heat dissipation. Make sure that the CPU and the heatsink are securely fastened and in good contact with each other. For dual channel configuration, you always need to install identical (the same brand, speed, size and chip-type) DDR2 DIMM pair in the slots of the same color. In other words, you have to install identical DDR2 DIMM pair in Dual Channel A (DDRII_1 and DDRII_2; Yellow slots; see p. This motherboard also allows you to install four DDR2 DIMMs for dual channel configuration, and please install identical DDR2 DIMMs in all four slots. If you want to install two memory modules, for optimal compatibility and reliability, it is recommended to install them in the slots of the same color. In other words, install them either in the set of yellow slots (DDRII_1 and DDRII_2), or in the set of orange slots (DDRII_3 and DDRII_4). If only one memory module or three memory modules are installed in the DDR2 DIMM slots on this motherboard, it is unable to activate the Dual Channel Memory Technology. If a pair of memory modules is NOT installed in the same Dual Channel, for example, installing a pair of memory modules in DDRII_1 and DDRII_3, it is unable to activate the Dual Channel Memory Technology . It is not allowed to install a DDR memory module into DDR2 slot; otherwise, this motherboard and DIMM may be damaged. If you adopt DDR2 1066 memory modules on this motherboard, it is recommended to install them on DDRII_3 and DDRII_4 slots. Please make sure to disconnect power supply before adding or removing DIMMs or the system components. When you playback HDCP-protected video from Blu-ray (BD) or HD-DVD disc, the content will be displayed only in one of the three monitors instead of all monitors. With the internal VGA output support (DVI-D, D-Sub and HDMI) and external add-on PCI Express VGA card, you can easily enjoy the benefits of surround display feature. Please refer to page 17 for proper expansion card installation procedures for details. Then connect other monitor cables to the corresponding connectors of the add-on PCI Express VGA cards on PCIE2 slot. dVI-D and HDMI monitors cannot display at the same time. You can only choose the combination: DVI-D + D-Sub or HDMI + D-Sub. Enter "Share Memory" option to adjust the memory capability to [32MB], [64MB], [128MB] [256MB] or [512MB] to enable the function of VGA/D-sub. Please make sure that the value you select is less than the total capability of the system memory. If you do not adjust the BIOS setup, the default value of "Share Memory", [Auto], will disable VGA/D-Sub function when the add-on VGA card is inserted to this motherboard. [. . . ] Therefore, the drivers you install can work properly. If you want to install Windows® XP / XP 64-bit / VistaTM / VistaTM 64-bit on your SATA / SATAII HDDs with RAID functions, please refer to the document at the following path in the Support CD for detailed procedures: . If you want to install Windows® XP, Windows® XP 64-bit, Windows® VistaTM or Windows® VistaTM 64-bit OS on your SATA / SATAII HDDs without RAID functions, please follow below procedures according to the OS you install. If you want to install Windows® XP or Windows® XP 64-bit on your SATA / SATAII HDDs without RAID functions, please follow below steps. [. . . ]
