What are the optimal BIOS settings for overclocking an ASUS ROG Maximus XIII Hero motherboard?

In today’s tech-savvy climate, the ASUS ROG Maximus XIII Hero motherboard stands as a beacon for enthusiasts eager to push their systems to the limit. The marriage of the Intel Core CPUs and the ROG Maximus XIII Hero motherboard opens a world of opportunities for overclocking endeavors. This detailed guide walks you through the optimal BIOS settings for overclocking this high-performance motherboard. Whether you are new to overclocking or a seasoned pro, these settings will help you extract every ounce of power from your rig.

Understanding the BIOS

Before diving into specific settings, it’s crucial to grasp what the BIOS entails. The BIOS (Basic Input/Output System) serves as the bridge between your motherboard hardware and the operating system. It is responsible for booting up your system and offers various options to tweak performance settings. For the ASUS ROG Maximus XIII Hero, understanding the BIOS is the first step to unlocking its true potential.

Entering the BIOS

To access the BIOS on the ASUS ROG Maximus XIII Hero, restart your computer and press the Delete key during the boot process. You will be greeted by the EZ Mode interface, a simplified view of your system’s data. For comprehensive tuning, switch to the Advanced Mode by pressing F7.

Navigating the BIOS

In Advanced Mode, various tabs like “Main,” “Extreme Tweaker,” “Advanced,” and “Monitor” become available. These tabs house the settings required to overclock your system efficiently.

CPU Overclocking Settings

Overclocking the Intel Core CPU on the ASUS ROG Maximus XIII Hero demands meticulous adjustments. Here’s a step-by-step guide to optimize your CPU settings.

Core Ratio

The core ratio is pivotal in defining the CPU’s operational speed. Adjusting the core ratio multiplies the base clock, resulting in an increased clock speed.

  1. Navigate to the “Extreme Tweaker” tab.
  2. Locate the “CPU Core Ratio” setting.
  3. Set the CPU Core Ratio to “Sync All Cores.”
  4. Enter a core ratio value. Start conservatively with a value of 50 for a 5 GHz overclock.

CPU Voltage

Voltage settings ensure that your CPU receives adequate power for stable overclocking. However, too much voltage can overheat and damage the CPU.

  1. Under “Extreme Tweaker,” find the “CPU Core/Cache Voltage” setting.
  2. Set it to “Manual Mode.”
  3. Input a starting voltage of 1.35V.

Load-Line Calibration

Load-Line Calibration (LLC) stabilizes the voltage supplied to the CPU. This is crucial to maintain stability during high loads.

  1. In the “Extreme Tweaker” tab, find “Load-Line Calibration.”
  2. Set LLC to Level 5 or Level 6 for a balanced voltage supply.

Thermal Management

Effective thermal management is essential. Ensure that you have a robust cooling solution in place, such as an RGB Corsair liquid cooler, to maintain safe temperatures.

Memory Overclocking Settings

Memory or RAM overclocking can significantly enhance system performance. The ASUS ROG Maximus XIII Hero’s BIOS provides multiple options for fine-tuning your RAM.

XMP Profile

The XMP (Extreme Memory Profile) automates memory overclocking, providing a simple yet effective method to boost RAM speed.

  1. Head to the “Extreme Tweaker” tab.
  2. Locate the “Ai Overclock Tuner” setting.
  3. Set it to “XMP” and select the preferred profile.

Manual Memory Timing

For more granular control, manual timing adjustments are available.

  1. Still under “Extreme Tweaker,” find the “Dram Timing Control” setting.
  2. Enter the primary timings provided on your RAM module.
  3. Start with a Command Rate of 1T and adjust the CAS Latency (CL), tRCD, tRP, and tRAS as needed.

Memory Voltage

Just like the CPU, your RAM needs adequate voltage to operate at higher speeds.

  1. In the “Extreme Tweaker” tab, find “DRAM Voltage.”
  2. Set the voltage to approximately 1.35V or as recommended by your RAM manufacturer.

Additional BIOS Settings

Several other settings within the BIOS can influence your overclocking success. Here are some additional adjustments to consider:

CPU Power Management

Disabling certain power-saving features can improve stability when overclocking.

  1. Navigate to the “Advanced” tab.
  2. Find “CPU Configuration.”
  3. Disable “Intel SpeedStep,” “C1E,” and other power-saving options.

VCCIO and VCCSA Voltage

Adjusting the VCCIO and VCCSA voltages can help stabilize the memory controller.

  1. In the “Extreme Tweaker” tab, find “VCCIO Voltage” and “VCCSA Voltage.”
  2. Set both to 1.15V-1.2V to begin with.

Fan Control

Proper cooling is critical. Adjust your fan curves to ensure efficient cooling.

  1. Go to the “Monitor” tab.
  2. Select “Q-Fan Configuration” and customize fan speeds.

Testing Stability and Performance

All the settings in the world mean nothing if they are not stable. After configuring your BIOS settings, testing stability is crucial.

Stress Testing

Utilize tools like Prime95 or AIDA64 to stress test your CPU and memory. Monitor temperatures and voltages closely using software like HWMonitor.


Benchmarking tools like Cinebench and 3DMark can provide performance comparisons before and after overclocking. Look for improvements in CPU and GPU scores.


Overclocking often requires patience and adjustments. If your system proves unstable, tweak the settings slightly.

  1. Lower the core ratio or voltage incrementally.
  2. Adjust memory timings or voltage if experiencing RAM instability.

Final Thoughts
