1.7.2 Memory conîÂÂgurations Y ou may install 512MB, 1GB, 2GB, and 4GB unbuffered ECC and non-ECC DDR3 DIMMs into the DIMM sockets. ⢠Y ou may install varying memory sizes in Channel A and Channel B. The system maps the total size of the lower-sized channel for the dual-channel conîÂÂguration. Any excess memory from the higher-sized channel is then mapped for single-channel operation. ⢠Always install DIMMs with the same CAS latency . For optimum compatibility , we recommend that you obtain memory modules from the same vendor . ⢠Due to the memory address limitation on 32-bit Windows î OS, when you install 4GB or more memory on the motherboard, the actual usable memory for the OS can be about 3GB or less. For effective use of memory , we recommend that you do any of the following: - Install a maximum of 3GB system memory if you are using a 32-bit Windows Install a maximum of 3GB system memory if you are using a 32-bit Windows î OS. - Use a 64-bit Windows Windows î OS if you want to install 4GB or more memory on the motherboard. ⢠This motherboard does not support DIMMs made up of 256 megabits (Mb) chips or less.

1.8 Expansion slots In the future, you may need to install expansion cards. The following sub-sections describe the slots and the expansion cards that they support. Unplug the power cord before adding or removing expansion cards. Failure to do so may cause you physical injury and damage motherboard components. 1.8.1 Installing an expansion card T o install an expansion card: 1. Before installing the expansion card, read the documentation that came with it and make the necessary hardware settings for the card. 2. Remove the system unit cover (if your motherboard is already installed in a chassis). 3. Remove the bracket opposite the slot that you intend to use. Keep the screw for later use. 4. Align the card connector with the slot and press îÂÂrmly until the card is completely seated on the slot. 5. Secure the card to the chassis with the screw you removed earlier . 6. Replace the system cover . When using PCI cards on shared slots, ensure that the drivers support âÂÂShare IRQâ or that the cards do not need IRQ assignments. Otherwise, conîÂÂicts will arise between the two PCI groups, making the system unstable and the card inoperable. 1.8.3 PCI slots The PCI slots support cards such as a LAN card, SCSI card, USB card, and other cards that comply with PCI speciîÂÂcations. 1.8.2 ConîÂÂguring an expansion card After installing the expansion card, conîÂÂgure it by adjusting the software settings. 1. T urn on the system and change the necessary BIOS settings, if any . See Chapter 2 for information on BIOS setup. 2. Assign an IRQ to the card. 3. Install the software drivers for the expansion card. 1.8.4 PCI Express x1 slot This motherboard supports PCI Express x1 network cards, SCSI cards, and other cards that comply with the PCI Express speciîÂÂcations. 1.8.5 PCI Express x16 slot This motherboard supports a PCI Express x16 graphics card that comply with the PCI Express speciîÂÂcations.

1.9 Jumpers 1. Clear RTC RAM (CLRTC) This jumper allows you to clear the Real T ime Clock (RTC) RAM in CMOS. Y ou can clear the CMOS memory of date, time, and system setup parameters by erasing the CMOS RTC RAM data. The onboard button cell battery powers the RAM data in CMOS, which include system setup information such as system passwords. Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default position. Removing the cap will cause system boot failure! T o erase the RTC RAM: 1. T urn OFF the computer and unplug the power cord. 2. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on pins 2-3 for about 5~10 seconds, then move the cap back to pins 1-2. 3. Plug the power cord and turn ON the computer . 4. Hold down the <Del> key during the boot process and enter BIOS setup to reenter data. ⢠If the steps above do not help, remove the onboard battery and move the jumper again to clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the battery . ⢠Y ou do not need to clear the RTC when the system hangs due to overclocking. For system failure due to overclocking, use the CPU Parameter Recall (C.P .R) feature. Shut down and reboot the system so the BIOS can automatically reset parameter settings to default values.

1.8 Expansion slots In the future, you may need to install expansion cards. The following sub-sections describe the slots and the expansion cards that they support. Unplug the power cord before adding or removing expansion cards. Failure to do so may cause you physical injury and damage motherboard components. 1.8.1 Installing an expansion card T o install an expansion card: 1. Before installing the expansion card, read the documentation that came with it and make the necessary hardware settings for the card. 2. Remove the system unit cover (if your motherboard is already installed in a chassis). 3. Remove the bracket opposite the slot that you intend to use. Keep the screw for later use. 4. Align the card connector with the slot and press îÂÂrmly until the card is completely seated on the slot. 5. Secure the card to the chassis with the screw you removed earlier . 6. Replace the system cover . When using PCI cards on shared slots, ensure that the drivers support âÂÂShare IRQâ or that the cards do not need IRQ assignments. Otherwise, conîÂÂicts will arise between the two PCI groups, making the system unstable and the card inoperable. 1.8.3 PCI slots The PCI slots support cards such as a LAN card, SCSI card, USB card, and other cards that comply with PCI speciîÂÂcations. 1.8.2 ConîÂÂguring an expansion card After installing the expansion card, conîÂÂgure it by adjusting the software settings. 1. T urn on the system and change the necessary BIOS settings, if any . See Chapter 2 for information on BIOS setup. 2. Assign an IRQ to the card. 3. Install the software drivers for the expansion card. 1.8.4 PCI Express x1 slot This motherboard supports PCI Express x1 network cards, SCSI cards, and other cards that comply with the PCI Express speciîÂÂcations. 1.8.5 PCI Express x16 slot This motherboard supports a PCI Express x16 graphics card that comply with the PCI Express speciîÂÂcations.

1.9 Jumpers 1. Clear RTC RAM (CLRTC) This jumper allows you to clear the Real T ime Clock (RTC) RAM in CMOS. Y ou can clear the CMOS memory of date, time, and system setup parameters by erasing the CMOS RTC RAM data. The onboard button cell battery powers the RAM data in CMOS, which include system setup information such as system passwords. Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default position. Removing the cap will cause system boot failure! T o erase the RTC RAM: 1. T urn OFF the computer and unplug the power cord. 2. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on pins 2-3 for about 5~10 seconds, then move the cap back to pins 1-2. 3. Plug the power cord and turn ON the computer . 4. Hold down the <Del> key during the boot process and enter BIOS setup to reenter data. ⢠If the steps above do not help, remove the onboard battery and move the jumper again to clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the battery . ⢠Y ou do not need to clear the RTC when the system hangs due to overclocking. For system failure due to overclocking, use the CPU Parameter Recall (C.P .R) feature. Shut down and reboot the system so the BIOS can automatically reset parameter settings to default values.
