Delovanje
Nastavitev BIOS-a:
The BIOS (Basic Input/Output System) is firmware that initializes hardware during the boot process. To enter the BIOS setup utility, press the DEL key repeatedly during system startup. Here you can configure various system settings such as boot order, date/time, CPU/memory settings, and enable/disable integrated peripherals. The GA-990FXA-UD3 features GIGABYTE's DualBIOS with Hybrid EFI technology, providing redundancy and support for large hard drives.
Namestitev gonilnika:
After installing your operating system, install the necessary drivers for the motherboard's components. You can use the driver CD included in your package or download the latest drivers from the official GIGABYTE webspletno mesto (www.gigabyte.com) for optimal performance and compatibility.
Vzdrževanje
- Vzdržujte čisto: Regularly clean dust from the motherboard and components using compressed air. Ensure fans are free of obstructions.
- Posodobitve BIOS-a: Občasno preverite GIGABYTE webspletno mesto za posodobitve BIOS-a. Posodobitve BIOS-a lahko izboljšajo stabilnost sistema, dodajo podporo za novo strojno opremo ali odpravijo napake. Pri posodabljanju BIOS-a natančno upoštevajte navodila podjetja GIGABYTE.
- Preverite povezave: Prepričajte se, da so vsi napajalni kabli, podatkovni kabli in razširitvene kartice varno nameščeni. Ohlapne povezave lahko povzročijo občasne težave.
Odpravljanje težav
- Brez napajanja: Ensure the power supply is connected correctly to the motherboard (24-pin and 8-pin connectors) and that the power supply switch is on. Check front panel power button connection.
- Brez zaslona: Verify that the graphics card is properly seated in its PCIe slot and that all necessary power connectors are attached. Ensure the monitor cable is securely connected to the graphics card.
- Sistem se ne zažene: Check memory modules are correctly installed. Try booting with only one memory module. Verify boot order in BIOS.
- Unexplained Slow Boot Times: Some users have reported slow boot times with this motherboard, even with SSDs. Ensure your BIOS is updated to the latest stable version. Verify that the SSD/HDD is set as the first boot device in the BIOS.
- Linux Compatibility (IOMMU/USB/Network Issues): For Linux users experiencing issues with network or USB 2.0 ports, it may be necessary to disable IOMMU in the BIOS and add "iommu=soft" to your GRUB boot options.
- Overclocking Instability: If overclocking, ensure adequate cooling and gradually increase voltages and frequencies. Refer to online resources and community forums for stable overclocking profiles for your specific CPU and memory.
- Audio Crackling: If experiencing audio crackling, try reinstalling the audio drivers. Ensure no conflicting audio software is running.
