You 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. To erase the RTC RAM: 1. Turn 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 key during the boot process and enter BIOS setup to re-enter data. Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default position. Removing the cap will cause system boot failure! If the steps above do not help, remove the onboard battery and move thejumper again to clear the CMOS RTC RAM data. After the CMOS clearance, reinstall the battery. Chapter 4: Motherboard information 2. VGA controller setting (3-pin VGA_SW1) This jumper allows you to enable or disable the onboard VGA controller. Set to pins 1–2 to activate the VGA feature. 3. CPU Fan and Chassis Fan control setting(3-pin CPUFAN_SEL1, CHAFAN_SEL1) These jumpers allow you to switch for fan pin selection. The CPUFAN_SEL1 jumper is for the CPU fans control and the CHAFAN_SEL1 jumper is for the front fans and rear fans control. Set to pins 1–2 when using 4-pin fans or pins 2–3 when using 3-pin fans. • If you use a 4-pin fan but set the jumper to pin 2-3, the fan you installed may not work. • If you use a 3-pin fan but set the jumper for a 4-pin fan, the fan control willnot work and the fan you installed will always run at full speed. ASUS RS500A-E6/PS4 4. LAN controller setting (3-pin LAN_SW1, LAN_SW2) These jumpers allow you to enable or disable the onboard Intel® 82574L Gigabit LAN controllers. Set to pins 1-2 to activate the Gigabit LAN feature. 5. DDR3 voltage control setting (4-pin LVDDR3_SEL1; LVDDR3_SEL2) These jumpers allow you to adjust the DIMM voltage. Set to pins 1–2 toselect 1.5V BIOS control, pins 2–3 to select 1.2V Force or 3–4 to select 1.35V Force. Chapter 4: Motherboard information 6. Force BIOS recovery setting (3-pin RECOVERY1) This jumper allows you to quickly update or recover the BIOS settings when it becomes corrupted. To update the BIOS: 1. Set the jumper to pins 2–3. 2. Insert the USB flash that contains the original or latest BIOS and turn on the system to recover or update the BIOS. 3. Shut down the system. 4. Set the jumper back to pins 1–2. 5. Turn on the system. ASUS RS500A-E6/PS4 4-8 Chapter 4: Motherboard information 4.3 Internal connectors 1. Serial ATA connectors (7-pin SATA1, SATA2, SATA3, SATA4; RED) (7-pin SATA5, SATA6; Black) Supported by the AMD® SP5100 chipset, these connectors are for the Serial ATA signal cables for Serial ATA hard disk drives that allows up to 3Gb/s of data transfer rate. 2. SAS connectors (7-pin SAS1, SAS2, SAS3, SAS4; Red) (7-pin SAS5, SAS6, SAS7, SAS8; Blue) This motherboard comes with eight (8) Serial Attached SCSI (SAS) connectors, the next-generation storage technology that supports both Serial Attached SCSI (SAS) and Serial ATA (SATA). Each connector supports one device. • These connectors function only when you install a PIKE RAID card. • Connect the SAS hard di...
