4. Configuración e instalación

4.1 Instalación da CPU

Carefully align your Intel LGA 1851 processor with the socket on the motherboard. Ensure the notches on the CPU match the alignment keys on the socket. Gently lower the CPU into place and secure it with the retention arm.

4.2 Instalación da memoria (RAM)

This motherboard supports DDR5 memory modules. Open the retention clips on the DIMM slots. Align the notch on the DDR5 memory module with the key in the DIMM slot. Press down firmly on both ends of the memory module until the clips snap into place.

4.3 Instalación de almacenamento (SSD M.2, unidades SATA)

The motherboard features two M.2 slots. For M.2 SSDs, remove the M.2 heatsink (if present), insert the M.2 SSD into the slot, and secure it with the provided M.2 screw and rubber package. The heatsink protects the M.2 slot, preventing performance degradation (throttling) of M.2 storage due to heat generated during long data transfers. For SATA drives, connect the SATA data cables (included) to the SATA 6Gb/s ports on the motherboard and to your storage devices.

4.4 Expansion Cards (GPU, other PCIe cards)

Insert your graphics card or other PCIe expansion cards into the appropriate PCIe slots. The primary PCIe 5.0 x16 slot features a reinforced metal sheath (SafeSlot) to securely mount video cards and enable high-speed data transfer.
