Chapter 1 Product introduction 1.1 Welcome! Thank you for buying an ASUS® F1A55 motherboard! The motherboard delivers a host of new features and latest technologies, making it another standout in the long line of ASUS quality motherboards! Before you start installing the motherboard, and hardware devices on it, check the items in your package with the list below. 1.2 Package contents Check your motherboard package for the following items.
AMD® A55 FCH (Hudson D2) Chipset AMD® A55 FCH (Hudson D2) is designed to support up to 5GT/s interface speed and PCI Express™ 2.0 x 16 (at x4 speed) graphics. ATI® CrossFireX™ Technology ATI’s CrossFireX™ boosts image quality along with rendering speed, eliminating the need to scale down screen resolution to get high quality images. CrossFireX™ allows higher antialiasing, anisotropic filtering, shading, and texture settings.
ASUS Anti-Surge Protection This special design protects expensive devices and the motherboard from damage caused by power surges from switching power supply unit (PSU). AI Suite II With its fast user-friendly interface, ASUS AI Suite II consolidates all the exclusive ASUS features into one simple to use software package. It allows you to supervise overclocking, energy management, fan speed control, and voltage and sensor readings.
ASUS CrashFree BIOS 3 ASUS CrashFree BIOS 3 is an auto-recovery tool that allows you to restore a corrupted BIOS file using the bundled support DVD or a USB flash disk that contains the BIOS file. C.P.R. (CPU Parameter Recall) The BIOS C.P.R. feature automatically restores the CPU default settings when the system hangs due to overclocking failure. C.P.R. eliminates the need to open the system chassis and clear the RTC data.
1.5 Motherboard overview 1.5.1 Placement direction 1.5.2 Screw holes When installing the motherboard, ensure that you place it into the chassis in the correct orientation. The edge with external ports goes to the rear part of the chassis as indicated in the image below. Place six screws into the holes indicated by circles to secure the motherboard to the chassis. DO NOT overtighten the screws! Doing so can damage the motherboard. Place this side towards the rear of the chassis.

1.6 Accelerated Processing Unit (APU) This motherboard comes with an FM1 socket designed for AMD® Fusion™ A- & E2- series accelerated processors with AMD® Radeon™ HD 6000 series graphics. Ensure that you use a APU designed for the FM1 socket. The APU fits in only one correct orientation. DO NOT force the APU into the socket to prevent bending the pins and damaging the APU! 1.6.1 Installing the APU To install a APU: 1. Locate the FM1 socket on the motherboard. F1A55 F1A55 processor socket FM1 2.
5. When the APU is in place, push down the socket lever to secure the APU. The lever clicks on the side tab to indicate that it is locked. 6. Install a APU heatsink and fan following the instructions that comes with the heatsink package. You can also refer to section 1.6.2 Installing heatsink and fan for instructions. 7. Connect the CPU fan cable to the CPU_FAN connector on the motherboard.
1.6.2 Installing the heatsink and fan Ensure that you use only AMD-certified heatsink and fan assembly. To install the CPU heatsink and fan: 1. Place the heatsink on top of the installed CPU, ensuring that the heatsink fits properly on the retention module base. • The retention module base is already installed on the motherboard upon purchase. • You do not have to remove the retention module base when installing the CPU or installing other motherboard components.
3. Align the other end of the retention bracket to the retention module base. A clicking sound denotes that the retention bracket is in place. Ensure that the fan and heatsink assembly perfectly fits the retention mechanism module base, otherwise you cannot snap the retention bracket in place. 4. Push down the retention bracket lock on the retention mechanism to secure the heatsink and fan to the module base. 5.
1.7.2 Memory configurations You may install 1GB, 2GB, and 4GB unbuffered non-ECC DDR3 DIMMs into the DIMM sockets. • You 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 configuration. Any excess memory from the higher-sized channel is then mapped for single-channel operation. • We recommend that you install the memory modules from the blue slots for better overclocking capability.

1.7.3 Installing a DIMM Unplug the power supply before adding or removing DIMMs or other system components. Failure to do so can cause severe damage to both the motherboard and the components. 2 1. Press the retaining clips outward to unlock a DIMM socket. 2. Align a DIMM on the socket such that the notch on the DIMM matches the DIMM slot key on the socket. DIMM notch 1 1 DIMM slot key Unlocked retaining clip A DIMM is keyed with a notch so that it fits in only one direction.
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 To install an expansion card: 1.
VGA configuration PCI Express operating mode PCIe x16_1 PCIe x16_2 Single VGA/PCIe card x16 (Recommended for single VGA card) N/A Dual VGA/PCIe card x16 x4 • In single VGA card mode, use the PCIe 2.0 x16_1 slot (blue) for a PCI Express x16 graphics card to get better performance. • We recommend that you provide sufficient power when running CrossFireX™ mode. See page 1-21 for details.
• 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. • You 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. 1.10 Connectors 1.10.
