ASUS Motherboards Microcode Update for Speculative Execution and Indirect Branch Prediction Side Channel Analysis Method

    Important Information about Meltdown and Spectre

    ASUS is aware that current Intel® and AMD microcode versions might be subject to recently identified security vulnerabilities, commonly known as Meltdown and Spectre. We are working diligently to update ASUS motherboards that support 6th, 7th or 8th Generation Intel Core™ processors or Intel Core X-Series processors for X99 and X299 platforms*, and also all AMD AM4 / TR4 processors for X399 / X470 / X370 / B350 / A320 platforms. We recommend customers update their systems by downloading and applying the latest BIOS, as soon as the relevant revision becomes available. We also encourage customers to review relevant security information from Intel and AMD, paying particular attention to the appropriate identification and mitigation measures.

    For detailed information about the security issues, please visit the Intel Security Center page or AMD Processor Security page.

    *Intel will not release microcode updates for some processors based on the X79/X58/P45 platforms. For details, please see the Intel Microcode Revision Guidance document at: https://newsroom.intel.com/wp-content/uploads/sites/11/2018/04/microcode-update-guidance.pdf.

    Resolution:

    • Step 1: Check below to see if your motherboard is listed.
    • Step 2: Download and install the latest BIOS to update affected platforms.
