AM5 motherboard for Ryzen 7000, 8000 and 9000

The GIGABYTE X870 AORUS INFINITY is an Extended ATX board built on the AMD X870 chipset for AM5 processors. It supports Ryzen 7000, 8000 and 9000 series CPUs and provides two DDR5 slots with a maximum capacity of 128 GB. Dual-channel memory can reach DDR5 11400 when overclocked using AMD EXPO or Intel XMP 3.0 profiles. The board targets enthusiasts who need high memory speed and extensive storage options.

PCIe 5.0 graphics and storage with CPU-dependent

The primary PCI Express x16 slot runs at PCIe 5.0 x16 with Ryzen 9000 and 7000 processors, but drops to PCIe 4.0 x8 or x4 with Ryzen 8000 series CPUs. A second x16-sized slot shares bandwidth; when populated the first slot operates at up to x8. One M.2 connector wired to the CPU supports PCIe 5.0 x4 SSDs on Ryzen 9000 and 7000, while Ryzen 8000 series limit it to PCIe 4.0. Four SATA 6 Gb/s ports and NVMe RAID 0, 1, 5 and 10 complete the storage picture, though RAID 5 requires a Ryzen 9000 CPU.

Straightforward installation

The 288-pin DDR5 slots and AM5 socket follow standard mounting procedures, and the I/O shield is pre-installed. Builders must remember that the second x16 slot shares lanes with the first, so a single graphics card should always go in the top slot. Populating the M.2 connector or the second x16 slot reduces primary-slot bandwidth, which can surprise users expecting full x16 throughput. Wireless LAN uses Wi-Fi 802.11 be and BLUETOOTH 5.4, while audio runs through a Realtek ALC1220 codec delivering 7.1 channels.

Questions sur cet article

Which DDR5 speed should I pick for this board?

The board is validated up to DDR5 11400 (OC) via AMD EXPO or Intel XMP 3.0 profiles, so choose a kit rated at or below that speed for guaranteed stability.

What does the DDR5 11400 (OC) figure mean once the board is running?

It is the maximum overclocked memory frequency the board can sustain with a compatible Ryzen 7000, 8000 or 9000 series CPU and an EXPO or XMP 3.0 kit; actual speed depends on the processor's memory controller.

How does the PCIe 5.0 x16 slot behave with different Ryzen generations?

Ryzen 9000 and 7000 series run the slot at PCIe 5.0 x16; Ryzen 8000 Phoenix 1 runs it at PCIe 4.0 x8; Phoenix 2 runs it at PCIe 4.0 x4. Populating the second x16 slot reduces the primary to x8.
