ASRock H310CM-HDV/M.2 SE UEFI Setup Utility

1 Introduction

This section introduces how to configure your system using the UEFI SETUP UTILITY. After turning on the computer, press F2 or Del to enter the UEFI SETUP UTILITY. Otherwise, the Power-On Self-Test (POST) will continue its test routine. If you want to enter the UEFI SETUP UTILITY after POST, you can restart the system by pressing Ctrl + Alt + Delete or the reset button on the system chassis. You can also restart the system by turning it off and then on again.

Due to continuous updates of UEFI software, the UEFI setup screens and descriptions provided are for reference only and may differ from what you see on your screen.

2 EZ Mode

By default, the EZ Mode screen appears when you enter the BIOS setup program. EZ Mode is a dashboard that displays various readings of the system's current status. You can check the most important system information, such as: CPU speed, DRAM frequency, SATA information, fan speed, etc.

Press F6 or click the “Advanced Mode” button in the upper right corner of the screen to switch to “Advanced Mode” for more options.

Key Functions in EZ Mode:

• 1 Help: Provides assistance.
• 2 Load UEFI Defaults: Loads default UEFI settings.
• 3 Save Changes and Exit: Saves changes and exits the setup.
• 4 Discard Changes: Discards any changes made.
• 5 Change Language: Allows changing the display language.
• 6 Switch to Advanced Mode: Switches to the Advanced Mode interface.

3 Advanced Mode

Advanced Mode provides more options for configuring BIOS settings. Refer to the following sections for detailed configuration.

To access EZ Mode, press F6 or click the “EZ Mode” button in the upper right corner of the screen.

3.1 UEFI Menu Bar

The top of the screen has a menu bar with the following options:

• Main: Displays system time/date information.
• Overclocking Tool: Configures overclocking settings.
• Advanced: Advanced system configuration.
• Tool: Useful tools.
• Hardware Monitor: Displays current hardware status.
• Boot: Configures boot settings and boot priority.
• Security: Security settings.
• Exit: Exits the current screen or the UEFI Setup Utility.

3.2 Navigation Keys

Use the ← and → keys to select options on the menu bar, and use the ↑ and ↓ keys to move the cursor up or down to select items. Then press Enter to enter a sub-screen. You can also use the mouse to click on the desired item.

Please check the following table for descriptions of each navigation key:

4 Main Screen

When you enter the UEFI SETUP UTILITY, the Main screen appears and displays a system overview.

My Favorites

Displays your favorite BIOS items. Press F5 to add/remove favorite items.

5 Overclocking Tool

In the Overclocking Tool screen, you can set overclocking functions.

CPU Configuration

Performance Mode

Defaults to the maximum Non-Turbo performance mode. This setting keeps the CPU flexible in its multiplier until the operating system takes over. Maximum Battery mode sets the CPU multiplier to x8 until the operating system takes over. It is recommended to set this option when overclocking BCLK.

FCLK Frequency

Sets the FCLK frequency.

AVX Frequency Offset

The AVX frequency offset setting adjusts the negative offset for the CPU multiplier under AVX load. The AVX load is heavier, so it reduces the AVX multiplier to ensure the maximum possible multiplier for SSE load.

BCLK Aware Voltage

BCLK Aware Voltage can be set to Enabled or Disabled. When set to Enabled, the pcode will consider the CPU V/F curve when calculating the CPU V/F curve. This is suitable for BCLK overclocking to avoid high voltage overrides.

Ring to Core Ratio Offset

Disabling the Ring to Core Ratio Offset allows the Ring and Core to operate at the same frequency.

Intel SpeedStep Technology

Intel SpeedStep Technology allows the processor to switch between multiple frequencies and voltages to achieve better power savings and thermal performance.

Intel Turbo Boost Technology

Intel Turbo Boost Technology allows the processor to operate at speeds above its basic operating frequency when the operating system requires it.

Intel Speed Shift Technology

Enable/Disable Intel Speed Shift Technology. Enabling this technology exposes the CPPC v2 interface, allowing hardware to control the P-state.

Long Duration Power Limit

Configures the package power limit 1 (Watts). When this limit is exceeded, the CPU multiplier will be reduced after a period of time. Lower limits protect the CPU and save power, while higher limits improve performance.

Long Duration Maintained

Configures how long it takes for the CPU multiplier to be reduced after exceeding the long duration power limit.

Short Duration Power Limit

Configures the package power limit 2 (Watts). When this limit is exceeded, the CPU multiplier will be immediately reduced. Lower limits protect the CPU and save power, while higher limits improve performance.

CPU Core Current Limit

Configures the current limit (Amperes) for the CPU in Turbo mode. Lower limits protect the CPU and save power, while higher limits improve performance.

GT Current Limit

Configures the current limit (Amperes) for the GPU in Turbo mode. Lower limits protect the GPU and save power, while higher limits improve performance.

GT Frequency

Configures the frequency of the integrated GPU.
