Socket AM4 ATX board with 128 GB DDR4 limit

The Gigabyte X570 UD is an ATX motherboard built for AMD processors that use the AM4 socket. It accepts up to 128 GB of DDR4 memory across its slots and provides a single PCI Express 3.0 x16 slot for a graphics card plus one legacy PCI slot. The rear panel includes one LAN port and one USB 3.1 Gen 2 Type-A connector.

Builders using AM4 CPUs who need a full-size board

This board suits anyone assembling a new system around a compatible AM4 processor and who wants the expansion room of an ATX form factor. It is not for builders who require more than one full-length PCIe x16 slot or who need additional rear USB ports beyond the single Gen 2 connector provided.

One PCI Express 3.0 x16 slot for graphics

The single PCIe 3.0 x16 slot is the specification that determines whether this motherboard fits your build. If your design calls for a discrete graphics card and no second x16 device, the slot count matches that requirement; if you need multiple x16 devices, this board will not meet it.

Questions about this item

What PCIe standard does the single x16 slot use, and what bandwidth does that cap it at?

The board provides one PCI Express 3.0 x16 slot, which limits graphics or add-in cards to Gen 3 speeds.

What physical space and mounting pattern does this ATX board require?

It follows the standard ATX form factor, so it fits any ATX-compatible case with the matching standoff layout and I/O shield cutout.

How is the board installed, and which step is most often missed?

Mount the standoffs for ATX, fit the supplied I/O shield first, then secure the board; the step people skip is installing the shield before the motherboard.
