4. Einrichtung und Installation
Follow these steps carefully to install your EVGA X299 Dark Motherboard and its components.
4.1. Vorbereitung des Motherboards
- Auspacken: Carefully remove the motherboard from its packaging. Place it on an anti-static surface or use the included Visual Guide / Bench Stand.
- CPU-Installation: Open the LGA 2066 socket lever. Align the CPU with the socket, ensuring the gold triangle on the CPU matches the indicator on the socket. Gently place the CPU into the socket without forcing it. Close the lever to secure the CPU.
- Installation des CPU-Kühlers: Install your compatible CPU cooler according to its manufacturer's instructions. If using a custom backplate, utilize the optional Socket 20XX Backplate provided.
- RAM-Installation: Open the clips on the DDR4 DIMM slots. Align the memory modules with the slots, ensuring the notch on the module matches the key in the slot. Press down firmly on both ends until the clips snap into place. Refer to your cooler's clearance for optimal slot usage.
4.2. Installation von Speichermedien
- M.2 SSDs: Locate the M.2 slots. Remove any protective covers or screws. Insert the M.2 SSD into the slot at an angle and secure it with the provided screw. Apply the included thermal pads for optimal cooling, especially for PCIe 4 M.2 drives. If using a Key-E M.2 device, use the vertical adapter.
- SATA-Laufwerke: Connect your SATA storage devices (HDDs/SSDs) to the SATA 6Gbit/s ports using the provided SATA data cables. Ensure power cables are also connected from your power supply.
- U.2 Drives: Connect U.2 drives to the dedicated U.2 ports if applicable.
4.3. Stromanschlüsse
Connect the 24-pin ATX power connector and the 8-pin CPU power connectors from your power supply to the corresponding ports on the motherboard. Ensure all connections are firm.
4.4. Expansion Cards and Peripherals
- Grafikkarten: Insert your graphics card(s) into the appropriate PCIe x16 slots. If installing multiple graphics cards for SLI, use the provided 3-Way SLI® Bridge. Ensure the PCI slot switches are enabled for the slots you intend to use.
- Andere PCIe-Karten: Install any other PCIe expansion cards as needed.
- Frontplattenanschlüsse: Connect your case's front panel headers (power button, reset button, USB, audio) to the corresponding pins on the motherboard. Use the USB 2.0 Header Bracket for additional USB 2.0 ports if required.
5. Bedienungsanleitung
Once your system is assembled, follow these steps for initial boot-up and configuration.
5.1. Erster Start und BIOS-Einrichtung
- Einschalten: Schließen Sie Monitor, Tastatur und Maus an. Schalten Sie Ihr System ein.
