APU & Heatsink Installation
Proper installation of the APU and heatsink is crucial for system stability and to prevent overheating. Follow these steps:
- Pull the socket lever sideways away from the socket, raising it to a 90-degree angle.
- Locate the gold arrow on the APU and align it with the corresponding mark on the socket. The APU can only be installed in the correct orientation.
- Ensure the APU pins are completely embedded into the socket and are not visible. Incorrect installation may cause permanent damage to the motherboard.
- Press the APU down firmly into the socket and close the lever. While closing the lever, press down on the APU with your fingers to ensure it remains properly seated.
- Apply a thin layer of thermal paste or thermal tape evenly on the top of the APU to aid heat dissipation and prevent overheating.
- Locate the CPUFAN connector on the motherboard.
- Place the heatsink onto the motherboard, ensuring the fan cable is oriented towards the CPUFAN connector and the heatsink fasteners align with the motherboard holes.
- Align the protrusion of the push-pin with the notch of the fastener and insert the two push-pins into the fasteners.
- Push down the push-pins until they are securely wedged into the motherboard holes. A click sound indicates the fastener is locked.
- Inspect the motherboard to confirm that the fastener ends are properly locked in place.
- Attach the fan cable to the CPUFAN connector on the motherboard.
Important:
- Confirm that the APU cooler has formed a tight seal with the APU before booting the system.
- Refer to the documentation included with the APU cooler package for more detailed installation instructions.

Memory Installation
The DIMM slots (DIMM1, DIMM2) are used for installing memory modules. For compatibility information, visit: http://www.msi.com/service/test-report/
Important:
- DDR3 memory modules are not interchangeable with DDR2 and are not backward compatible. Always install DDR3 memory modules in DDR3 DIMM slots.
- Due to chipset resource usage, the system may only detect up to 31+ GB of memory (not the full 32 GB) when all DIMM slots are populated with 8GB memory modules.

BIOS Setup
Default BIOS settings optimize performance and system stability. You may need to access Setup when:
- An error message prompts you to run SETUP during boot.
- You wish to change settings for customized features.
Important:
- To restore optimal performance and stability after changing BIOS settings, load default settings by selecting "Restore Defaults" and pressing Enter.
- If unfamiliar with BIOS settings, it is recommended to keep default settings to prevent system damage or boot failures due to incorrect configuration.
Entering BIOS Setup
Power on the computer. During the Power On Self Test (POST), when the prompt appears, press the <DEL> key to enter BIOS Setup. Alternatively, press F11 to enter the Boot Menu.
If the prompt disappears before you can respond, restart the system by turning it off and on again, or by pressing the RESET button. You can also restart by pressing <Ctrl>, <Alt>, and <Delete> simultaneously.

OC Menu (Overclocking)
Important: Manual overclocking is recommended for advanced users only. Overclocking is not guaranteed and improper execution can void your warranty or damage hardware. For easier overclocking, MSI recommends using the OC Genie utility.
Frequency Information
- Current CPU/ DRAM/ NB/ GPU Frequency: Displays current frequencies (Read-only).
- Adjust CPU Ratio [Auto]: Sets the CPU ratio to determine clock speed. This can only be changed if the processor supports it.
- Adjusted CPU Frequency: Shows the adjusted CPU frequency (Read-only).
- DRAM Frequency [Auto]: Sets the DRAM frequency. Overclocking behavior is not guaranteed.
- Adjusted DRAM Frequency: Shows the adjusted DRAM frequency (Read-only).
Memory Timing Settings
- DRAM Timing Mode [Auto]: Selects the memory timing mode.
- [Auto]: DRAM timings are determined by SPD of installed memory modules.
- [Link]: Allows manual configuration of DRAM timing for all memory channels.
- [UnLink]: Allows manual configuration of DRAM timing for respective memory channels.
- Advanced DRAM Configuration: Accesses sub-menu for detailed memory timing settings. Changing memory timing can lead to instability or unbootable systems; clear CMOS if issues occur.
Spread Spectrum
This function reduces Electromagnetic Interference (EMI) by modulating clock generator pulses.
- [Enabled]: Reduces EMI.
- [Disabled]: Enhances CPU Base clock overclocking ability.
Important:
- For optimal stability and performance without EMI issues, leave at [Disabled]. If EMI is present, select Spread Spectrum for reduction.
- Higher Spread Spectrum values reduce EMI but may decrease system stability. Consult local EMI regulations for optimal values.
- Disable Spread Spectrum when overclocking, as jitter can cause processor lock-ups.
Voltage and Detection Settings
- DRAM Voltage [Auto]: Sets memory voltage. "Auto" lets BIOS set it, or manual setting is possible.
- CPU Memory Changed Detect [Enabled/Disabled]: Enables or disables a warning message during boot if CPU or memory is replaced. [Enabled] shows a warning and loads defaults for new devices; [Disabled] keeps current settings.
- OC Retry Count: If overclocking fails, setting this to [1,3] allows the system to reboot 1 or 3 times with the same configuration. If it fails repeatedly, defaults are restored.
Overclocking Profiles
Manage overclocking profiles (1-6). Save or load profiles to/from USB flash drives (FAT32 format only).
System Information
- CPU Specifications: Displays installed CPU information (Read-only). Accessible via F4.
- CPU Technology Support: Shows key features supported by the installed CPU (Read-only).
- MEMORY-Z: Displays all settings and timings of installed memory.
CPU Features
- AMD Cool'n'Quiet [Auto/Enable/Disabled]: Manages AMD Cool'n'Quiet technology for dynamic CPU speed and power reduction. [Auto] depends on AMD design. [Enable] activates the technology. [Disabled] turns it off.
- Important: Adjusting CPU Ratio may disable Cool'n'Quiet. For CPUs supporting Turbo Core Tech., set both Turbo Core Tech. and Cool'n'Quiet to Disabled to maintain default CPU core speed.
- SVM Mode [Enabled/Disabled]: Enables or disables CPU Virtualization, allowing multiple operating systems in independent partitions.
- Core C6 State [Enabled/Disabled]: Enables or disables C6 state support. When enabled, CPU cores save state and reduce voltage to zero, but wake-up time increases. [Disabled] turns off this function.
