- Align the CPU's triangle mark with the socket's triangle mark and gently place the CPU into the socket.
- Lower the retention lever to secure the CPU.
- Apply thermal paste evenly onto the CPU surface.
- Mount the CPU cooler heatsink onto the CPU.
- Connect the CPU heatsink's 4-pin fan power connector to the CPU_FAN header on the motherboard.
⚠️ Important:
- Ensure the motherboard supports the CPU.
- Always unplug the power cord before installing or removing the CPU.
- Retain the CPU protective cap after installation.
- Do not power on the system if the CPU cooler is not installed.
- Confirm the CPU heatsink forms a tight seal with the CPU.
- Protect CPU socket pins with a plastic cap when the CPU is not installed.
- Do not force the CPU into the socket; ensure the lever is lifted.
Install Memory
To install memory modules:
- Wrench the latches on both sides of the memory slot outwards.
- Align the memory module's notch with the slot's notch.
- Insert the memory module firmly into the slot.
- Flip the latches on both sides of the slot to lock the memory module in place.
⚠️ Important:
- Ensure memory compatibility with the motherboard. Using memory of the same capacity, brand, speed, and chips is recommended for stability.
- Always turn off the computer and unplug the power cord before installing memory.
- Memory modules have a foolproof design; if it doesn't fit, try rotating it.
- Memory stability and compatibility can depend on the CPU and overclocking.
- This motherboard supports 4-Channel Technology, requiring at least two modules for dual-channel and four for quad-channel. Server and desktop memory cannot be mixed.

BIOS Setup
What is BIOS?
BIOS (Basic Input and Output System) is firmware that records hardware parameters and initializes the system upon startup. It performs the Power-On Self-Test (POST), identifies, configures, and tests hardware, and connects the computer to the operating system. The BIOS Setup program allows modification of basic system configuration settings.
When the computer is off, the motherboard's battery supplies power to the CMOS to retain BIOS configuration values.
⚠️ Important:
BIOS flashing is risky. It is recommended not to flash the BIOS unless necessary, and to do so with caution to avoid system malfunction.
BIOS Setup Utility
The default BIOS settings are optimized for system stability. It is recommended not to alter them unless required, to prevent instability or boot failures.
⚠️ Important:
BIOS items are updated regularly for performance improvements. Descriptions are for reference only and may differ slightly from the latest BIOS versions.
Entering BIOS Setup
When the computer starts, it performs a self-test. Upon completion, a message like "Press DEL key to enter Setup Menu" is displayed. Press the DEL key at this time. If the message disappears quickly, restart the computer (using the reset button or Ctrl+Alt+Delete) and repeatedly press the "Del" key immediately after starting to ensure entry into BIOS mode.
Image shows the Aptio Setup Utility BIOS screen, displaying information such as BIOS Vendor (American Megatrends), BIOS Version (E5-MR9A PRO MAX), System Date, and System Time. It also shows navigation instructions (↑↓: Select Item, Enter: Select, +/-: Change Opt., F1: Help, F2: Previous Values, F3: Optimized Defaults, F4: Save & Exit, ESC: Exit).Reset BIOS
To restore default BIOS settings, you can:
- Enter BIOS Setup and press F6 to load optimized defaults.
- Short the Clear CMOS jumper on the motherboard.
⚠️ Important:
Ensure the computer is powered off before clearing CMOS data. Refer to the Clear CMOS jumper section for details.
