1.2 Before you proceed

Take note of the following precautions before you install motherboard components or change any motherboard settings.

• Unplug the power cord from the wall socket before touching any component.

• Before handling components, use a grounded wrist strap or touch a safely grounded object or a metal object, such as the power supply case, to avoid damaging them due to static electricity.

• Hold components by the edges to avoid touching the ICs on them.

• Whenever you uninstall any component, place it on a grounded antistatic pad or in the bag that came with the component.

• Before you install or remove any component, ensure that the ATX power supply is switched off or the power cord is detached from the power supply. Failure to do so may cause severe damage to the motherboard, peripherals, or components.

1.3 Motherboard overview

Before you install the motherboard, study the configuration of your chassis to ensure that the motherboard fits.

Ensure that you unplug the power cord before installing or removing the motherboard.

Failure to do so can cause you physical injury and damage motherboard components.

Authorization (RMA) requests only if the motherboard comes with the cap on the

LGA1155 socket.

• The product warranty does not cover damage to the socket contacts resulting from incorrect CPU installation/removal, or misplacement/loss/incorrect removal of the PnP cap.

To install an APU:

1. Locate the FM1 socket on the motherboard.

Ensure that the socket lever is lifted up to a 90°-100° angle; otherwise, the APU will not fit in completely.

3. Position the APU above the socket such that the APU corner with the gold triangle matches the socket corner with a small triangle.

4. Carefully insert the APU into the socket until it fits in place.

The APU fits only in one correct orientation.

DO NOT force the APU into the socket to prevent bending the pins and damaging the

APU!

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.

DO NOT forget to connect the CPU fan connector! Hardware monitoring errors can occur if you fail to plug this connector.

Chapter 1: Product introduction

1.4.2 Installing the heatsink and fan

Use only AMD-certified heatsink and fan assemblies.

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.

• If you purchased a separate CPU heatsink and fan assembly, apply Thermal Interface

Material to the CPU heatsink or CPU before you install the heatsink and fan assembly.

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. When the fan and heatsink assembly is in place, connect the CPU fan cable to the connector on the motherboard labeled CPU_FAN.

DO NOT forget to connect the CPU fan connector! Hardware monitoring errors can occur if you fail to plug this connector.

1.5 System memory

1.5.1 Overview

This motherboard comes with four Double Data Rate 3 (DDR3) Dual Inline Memory Module

(DIMM) sockets. A DDR3 module has the same physical dimensions as a DDR2 DIMM but is notched differently to prevent installation on a DDR2 DIMM socket. DDR3 modules are developed for better performance with less power consumption. The figure illustrates the location of the DDR3 DIMM sockets:

DIMM_A1 DIMM_A2 DIMM_B1 DIMM_B2

Channel Sockets

Channel A DIMM_A1 and DIMM_A2

Channel B DIMM_B1 and DIMM_B2

F1A55 R2.0

F1A55 R2.0 240-pin DDR3 DIMM sockets

1.5.2 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 using the blue slots for better overclocking capability.

• Always install DIMMs with the same CAS latency. For optimal compatibility, we recommend that you install memory modules of the same version or date code (D/C) from the same vendor. Check with the retailer to get the correct memory modules.

• When overclocking, some AMD CPU models may not support DDR3 1866 MHz or higher frequency DIMMs.

• Due to the memory address limitation on 32-bit Windows ® 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:

- Use a maximum of 3GB system memory if you are using a 32-bit Windows ® OS.

- Install a 64-bit Windows motherboard.

® OS if you want to install 4GB or more on the

ASUS F1A55 R2.0

1-14

• This motherboard does not support DIMMs made up of 512 megabits (Mb) chips or less.

• Memory modules with memory frequency higher than 2133 MHz and its corresponding timing or the loaded X.M.P. Profile is not the JEDEC memory standard. The stability and compatibility of these memory modules depend on the

CPU’s capabilities and other installed devices.

• The maximum 64GB memory capacity can be supported with 16GB or above

DIMMs. ASUS will update the memory QVL once the DIMMs are available in the market.

• The default memory operation frequency is dependent on its Serial Presence Detect

(SPD), which is the standard way of accessing information from a memory module.

Under the default state, some memory modules for overclocking may operate at a lower frequency than the vendor-marked value. To operate at the vendor-marked or at a higher frequency, refer to section 2.4 Ai Tweaker menu for manual memory frequency adjustment.

• For system stability, use a more efficient memory cooling system to support a full memory load (4 DIMMs) or overclocking condition.

1.7 Jumpers

Clear RTC RAM (3-pin CLRTC)

This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. 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.

F1A55 R2.0 Clear RTC RAM

Normal

(Default)

Clear RTC

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 <Del> key during the boot process and enter BIOS setup to reenter data.

ASUS F1A55 R2.0

1-21

1-22

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 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, then the BIOS automatically resets parameter settings to default values.

1.9 Onboard switch

Onboard switches allow you to fine-tune performance when working on a bare or opencase system. This is ideal for overclockers and gamers who continually change settings to enhance system performance.

MemOK! switch

Installing DIMMs that are incompatible with the motherboard may cause system boot failure, and cause the DRAM_LED near the MemOK! to switch lights continuously.

Press and hold the MemOK! switch until the DRAM_LED starts blinking to begin automatic memory compatibility tuning for successful boot.

F1A55 R2.0

F1A55 R2.0 MemOK! switch

• Refer to section 1.12 Onboard LEDs for the exact location of the DRAM_LED.

• The DRAM_LED also lights up when the DIMM is not properly installed. Turn off the system and reinstall the DIMM before using the MemOK! function.

• The MemOK! switch does not function under a Windows® OS environment.

• During the tuning process, the system loads and tests failsafe memory settings. It takes about 30 seconds for the system to test one set of failsafe settings. If the test fails, the system reboots and tests the next set of failsafe settings. The blinking speed of the DRAM_LED increases, indicating different test processes.

• Due to memory tuning requirements, the system automatically reboots when each timing set is tested. If the installed DIMMs still fail to boot after the whole tuning process, the DRAM_LED lights up continuously. Replace the DIMMs with ones recommended in the Memory QVL (Qualified Vendors Lists) in this user manual or on the ASUS website at www.asus.com.

• If you turn off the computer and replace DIMMs during the tuning process, the system continues memory tuning after turning on the computer. To stop memory tuning, turn off the computer and unplug the power cord for about 5–10 seconds.

• If your system fail to boot due to BIOS overclocking, press the MemOK! switch to boot and load BIOS default settings. A message will appear during POST reminding you that the BIOS has been restored to its default settings.

• We recommend that you download and update to the latest BIOS version from the

ASUS website at www.asus.com after using the MemOK! function.
