Socket AM4 ATX platform

The GIGABYTE B450 AORUS PRO is an ATX motherboard built around the AMD B450 chipset for Socket AM4 Ryzen processors. It provides four 288-pin DDR4 slots supporting memory speeds up to 3200 MHz and a maximum capacity of 64 GB. The board delivers a single PCI Express 3.0 x16 slot alongside two PCI Express 2.0 x16 slots and one x1 slot for expansion.

Builders needing one full-speed GPU slot

This board suits builders who need a single graphics card running at PCI Express 3.0 x16 speeds plus additional cards at x16 electrical x4 or x1 speeds. It also provides six SATA 6Gb/s ports and two M.2 sockets for storage. Users who require multiple full-speed x16 links should look at a different chipset.

One PCI Express 3.0 x16 slot

The decisive specification is the single PCI Express 3.0 x16 slot, which sets the limit for high-bandwidth add-in cards. If the build calls for only one such device, this motherboard matches the requirement; if it calls for more, a different platform is needed.

Questions about this item

How can I confirm the board is running DDR4 at 3200 MHz after setup?

Enter the BIOS or use a hardware monitor in Windows and verify the memory frequency reads 3200 MHz for the installed DDR4 modules.

What comes in the box and which essential parts must I purchase separately?

The motherboard includes the ATX board, I/O shield, SATA cables and manual; you must buy a Ryzen AM4 CPU, DDR4 DIMMs, storage drives and an ATX power supply separately.

Which memory capacity should I choose for the four DDR4 slots?

Populate the four slots with matching DDR4 modules up to 16 GB each to reach the 64 GB maximum; 8 GB sticks give 32 GB total, 16 GB sticks give 64 GB total.
