  • How do I use the USB BIOS Flashback feature on the Asus STRIX X99 motherboard?

    The USB BIOS Flashback feature allows you to update the BIOS without entering the existing BIOS or operating system. To use it:

    1. Place the bundled support DVD into the optical drive and install the USB BIOS Flashback Wizard. Follow the onscreen instructions.
    2. Insert the USB storage device containing the latest BIOS version into the USB Flashback port (the USB port hole marked in green on the I/O shield). USB BIOS Flashback
    3. Launch the USB BIOS Flashback Wizard to automatically download the latest BIOS version.
    4. Shut down your computer.
    5. Press the BIOS Flashback button for three seconds until the Flashback LED blinks three times, indicating that the function is enabled.
    6. Wait until the light goes out, which indicates that the BIOS updating process is completed.

    It is recommended to use a USB 2.0 storage device for better compatibility and stability. Do not unplug the portable disk, power system, or press the CLR_CMOS button while the BIOS update is ongoing. If the light flashes for five seconds and turns into a solid light, it means the BIOS Flashback is not operating properly, possibly due to improper installation of the USB storage device or filename/file format error. In this case, restart the system to turn off the light.

    Install a 64-bit Windows OS when you want to install 4 GB or more on the ® motherboard. c) For more details, refer to the Microsoft support site at http://support.microsoft. ® com/kb/929605/en-us. • The default memory operation frequency is dependent on its Serial Presence Detect (SPD), which is the standard way of accessing information from a memory module. Under the default state, some memory modules for overclocking may operate at a lower frequency than the vendor-marked value. To operate at the vendor-marked or at a higher frequency, refer to section 3.5 Ai Tweaker menu for manual memory frequency adjustment. • For system stability, use a more efficient memory cooling system to support a full memory load (8 DIMMs) or overclocking condition. • Always install the DIMMS with the same CAS Latency. For an optimum compatibility, we recommend that you install memory modules of the same version or data code (D/C) from the same vendor. Check with the vendor to get the correct memory modules. • The design of the DIMM fan may vary. Ensure that the DIMM fan fits to the motherboard. ASUS STRIX X99 GAMING...

    1.1.6 Onboard buttons and switches Onboard buttons and switches allow you to fine-tune performance when working on a bare or open-case system. This is ideal for overclockers and gamers who continually change settings to enhance system performance. Power-on button The motherboard comes with a power-on button that allows you to power up or wake up the system. The LED near the button also lights up when the system is plugged to a power source indicating that you should shut down the system and unplug the power cable before removing or installing any motherboard component.
  • Page 25 • Refer to section 1.1.8 Onboard LEDs for the exact location of the DRAM_LED. • The DRAM_LED also lights up when the DIMM is not properly installed. Turn off the system and reinstall the DIMM before using the MemOK! function. • The MemOK! button does not function under Windows OS environment. ® • During the tuning process, the system loads and tests failsafe memory settings. It takes about 30 seconds for the system to test one set of failsafe settings. If the test fails, the system reboots and tests the next set of failsafe settings. The blinking speed of the DRAM_LED increases, indicating different test processes. • Due to memory tuning requirement, the system automatically reboots when each timing set is tested. If the installed DIMMs still fail to boot after the whole tuning process, the DRAM_LED lights continuously. Replace the DIMMs with ones recommended in the Memory QVL (Qualified Vendors Lists) in this user manual or at www.asus.com. • If you turn off the computer and replace DIMMs during the tuning process, the system continues memory tuning after turning on the computer. To stop memory tuning, turn off the computer and unplug the power cord for about 5–10 seconds. • If your system fails to boot up due to BIOS overclocking, press the MemOK! button to boot and load the BIOS default settings. A message will appear during POST reminding you that the BIOS has been restored to its default settings. • We recommend that you download and update to the latest BIOS version from www.asus.com after using the MemOK! function.

    Plug the power cord and turn ON the computer. Hold down the <Delete> key during the boot process and enter BIOS setup to re-enter data. Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default position. Removing the cap will cause system boot failure! • If the steps above do not help, remove the onboard battery and move the jumper again to clear the CMOS RTC RAM data. After the CMOS clearance, reinstall the battery. • You do not need to clear the RTC when the system hangs due to overclocking. For system failure due to overclocking, use the C.P.R. (CPU Parameter Recall) feature. Shut down and reboot the system so the BIOS can automatically reset parameter settings to default values. • Due to the chipset behavior, AC power off is required to enable C.P.R. function.
