The ASRock Z68 Extreme4 Gen3 motherboard, a popular choice for enthusiasts and gamers in the early 2010s, offered a compelling blend of features and performance. A crucial component of any motherboard is its BIOS (Basic Input/Output System), the firmware that initializes the hardware and provides the interface for configuring system settings. This article provides an overview of the ASRock Z68 Extreme4 Gen3 BIOS version 2.20, its features, and where to find the download. Understanding the BIOS is critical for optimizing your system’s performance and ensuring compatibility with various hardware components.
Understanding the BIOS
Before delving into the specifics of the 2.20 update, it’s essential to understand what the BIOS does. The BIOS is the first software that runs when you power on your computer. Its primary functions include:
- Power-On Self-Test (POST): The BIOS performs a series of diagnostic tests to ensure that all essential hardware components (CPU, memory, storage devices, etc.) are functioning correctly.
- Hardware Initialization: It initializes and configures the hardware components, enabling them to communicate with the operating system.
- Boot Loader: The BIOS locates and loads the operating system from the designated boot device (hard drive, SSD, USB drive, etc.).
- Setup Utility: It provides a user interface (often accessed by pressing a key like Delete, F2, or F12 during startup) that allows you to configure various system settings, such as boot order, CPU clock speeds, memory timings, and fan speeds.
Updating the BIOS can be a crucial step in improving system stability, adding support for new hardware, and addressing security vulnerabilities. However, it is essential to proceed with caution, as a failed BIOS update can render your motherboard unusable.

Updating the BIOS: A Word of Caution
Updating the BIOS is a critical process that should be approached with caution. A failed BIOS update can render your motherboard unusable, requiring specialized equipment to recover (if possible). Before proceeding with a BIOS update, consider the following:
- Is the Update Necessary? Only update the BIOS if you are experiencing a specific issue that the update addresses or if you need support for new hardware. If your system is running stable and you don’t need any new features, there’s no need to update the BIOS.
- Read the Instructions: Carefully read the instructions provided by ASRock for updating the BIOS. These instructions will outline the recommended method for updating the BIOS and any precautions you should take.
- Backup Your Existing BIOS: If possible, back up your existing BIOS before performing the update. This will allow you to revert to the previous version if something goes wrong. Some motherboards have a dual-BIOS feature, which provides a backup BIOS in case the primary BIOS fails.
- Use a Reliable Power Source: Ensure that your computer is connected to a reliable power source during the BIOS update process. A power outage during the update can corrupt the BIOS and render your motherboard unusable.
- Do Not Interrupt the Update: Do not interrupt the BIOS update process once it has started. This includes turning off the computer, restarting it, or unplugging the power cord.
- Use the Correct BIOS File: Ensure that you are using the correct BIOS file for your motherboard model (ASRock Z68 Extreme4 Gen3) and revision. Using the wrong BIOS file can damage your motherboard.
Methods for Updating the BIOS
ASRock typically provides several methods for updating the BIOS, including:
- Instant Flash: A built-in BIOS utility that allows you to update the BIOS from a USB drive. This is generally the easiest and safest method.
- DOS Flash: Updating the BIOS from a DOS environment using a bootable USB drive.
- Windows-Based Update: Updating the BIOS from within Windows using a special utility. This method is generally not recommended due to the risk of interruption.
Refer to the ASRock Z68 Extreme4 Gen3 motherboard manual for detailed instructions on how to use each method.
