Hardware Installation

This section of the manual guides you through installing the CPU, memory, and storage devices on your Gigabyte B550 UD AC motherboard.

Installing the CPU

Before you install the CPU, make sure the power supply is disconnected from the wall outlet. Carefully remove the CPU cooler and its mounting bracket from the motherboard. Locate the CPU socket on the motherboard, which is a rectangular cutout with a lever on one side. The lever should be in the unlocked position. Align the CPU with the socket’s arrow markings, ensuring the notch on the CPU aligns with the socket’s corresponding notch. Gently lower the CPU into the socket, ensuring it sits flush with the socket. Once the CPU is in place, carefully lock the lever by pressing it down until it clicks into place. Make sure the lever is completely closed. Next, apply thermal paste to the top of the CPU. A small pea-sized amount is sufficient. Carefully align the CPU cooler’s mounting bracket over the CPU and gently press it down until it clicks into place. Securely attach the cooler’s fan to the mounting bracket. Double-check that all screws are securely fastened.

Installing Memory

Locate the DDR4 memory slots on the motherboard. They are typically black and have a small clip on each side. Open the clips by gently pushing them outwards. Align the memory module’s notch with the corresponding notch on the memory slot. The memory module should only fit in one direction. Gently push the memory module into the slot until it clicks into place. Ensure both clips are securely closed. For optimal performance, install memory modules in pairs, starting with the slots closest to the CPU. Refer to the motherboard’s manual for specific memory slot configurations for dual-channel operation. If installing multiple memory modules, make sure they are all the same type, speed, and capacity for compatibility. Once the memory modules are installed, close the computer case and connect the power supply.

Installing Storage Devices

The Gigabyte B550 UD AC motherboard offers various options for storage devices, including SATA and M.2 slots. Locate the SATA ports on the motherboard, usually labeled SATA1-6.

There are two slots, one for NVMe and the other for SATA-based M.2 SSDs. Align the SSD with the M.2 slot and gently push it into place. Secure the SSD with the screw provided. Make sure the SSD is correctly oriented in the slot, as indicated by the keying mechanism. Refer to the motherboard manual for specific instructions on installing M.2 SSDs and for the correct screw size.
