Gigabyte B450M DS3H WiFi (rev. 1.0/1.1/1.2/1.3)
The quintessential budget AM4 micro-ATX workhorse, supercharged with integrated wireless connectivity.
Overview
How It Works
Install the CPU and Cooler
Insert the AM4 processor into the zero-insertion-force socket, lock the retention arm, and apply thermal paste before mounting either the stock AMD Wraith cooler or an aftermarket solution. Secure the cooler to the pre-installed motherboard backplate.
Configure Memory and Storage
Populate the DDR4 DIMM slots (slots DDR4_1 and DDR4_2 for dual-channel priority) and install an M.2 NVMe SSD into the primary M.2 slot, taking care to secure it with the provided standoff and screw.
Connect Power and Expansion
Plug in the 24-pin ATX main power and 8-pin 12V CPU power cables. Install your graphics card into the primary PCIe 3.0 x16 slot and connect front panel header cables, SATA drives, and the Wi-Fi antenna to the rear I/O.
Flash BIOS and Boot
Power on the system and enter the UEFI BIOS. If using a newer Ryzen 5000-series CPU, ensure the BIOS is updated to the required version (e.g., F60 or newer) using the built-in Q-Flash utility before configuring XMP memory profiles.

Setup Tips
Attach the External Wi-Fi Antenna
Always screw the included dual-band antenna securely onto the gold threaded jacks on the rear I/O. Leaving these disconnected will result in extremely poor Wi-Fi and Bluetooth reception, even if you are positioned right next to your router.
Verify BIOS Version for Ryzen 5000 Series
Before assembling your PC with a Zen 3 processor, check the box for a 'Ryzen 5000 Desktop Ready' sticker. If missing, prepare a USB drive with the latest BIOS file and be ready to perform a boot sequence with an older AM4 processor if needed.
Enable XMP in UEFI
By default, your high-speed RAM will run at standard JEDEC speeds (2133MHz or 2666MHz). Restart your PC, press Del to enter the BIOS, navigate to the M.I.T. tab, and enable the Extreme Memory Profile (X.M.P.) to unleash your RAM's rated frequency.
Install the Correct Motherboard Standoffs
This is a Micro-ATX board, but it is slightly narrower than standard mATX dimensions. Ensure you align and install only the standoffs that correspond to this board's mounting holes in your PC case to prevent short circuits.
