Gigabyte X870 Aorus Infinity Motherboard Review: limited-edition, designed for extreme overclocking, but pricey for X870

Gigabyte’s X870 Aorus Infinity blends extreme overclocking ability and tools with good all-around features and aesthetics. But you’ll have to pay up for this limited-edition board’s flexibility.

At Computex 2026, we saw Gigabyte’s concept

motherboard using that incredible-looking space-age material for VRM cooling, along with something more practical: the X870 Aorus Infinity, a production board, not a concept. The Infinity is made for overclockers. Just look at the right edge: All those buttons and voltage read points make pushing the limits even easier. It sports a two-DIMM design, with the DRAM slots above the socket, prioritizing speed over capacity. Priced at an eye-opening

, it's far from cheap (it is a 40th-anniversary limited-edition board), even for the enthusiast X870E platform, but it offers a wide range of features that work for nearly everyone.

As far as specifications go, the Aorus Infinity is well-equipped for an X870 board. You get eight total USB ports on the rear IO (one USB4), three M.2 sockets (one PCIe 5.0), and four SATA ports for storage, fast networking with 5 GbE and Wi-Fi 7 (320 MHz), and a quality last-gen flagship-class audio codec. And of course, there are all of the features designed for overclocking, including robust power delivery and the Overclocking kit, with several buttons and voltage read points, to take some of the complications of extreme overclocking down a notch. Gigabyte also lists support for a staggering DDR5-11400(OC), but it needs manual tweaking, specialized BIOS fine-tuning, and the right hardware (likely an APU with an excellent IMC).

On the performance front, the X870 Aorus Infinity delivered average-to-above-average results across most tests, using our primary Kingston DDR5-6000 kit, which is what we like to see. It proved competent not only in daily office tasks and other productivity functions, but also as a solid gaming platform. Overall, this board is a well-rounded performer.

Below, we’ll examine the Aorus Infinity’s performance and other features, and decide if it has a chance to make our list of the best motherboards. But before we share test results and discuss details, here are the specifications from the Gigabyte website.

The Aorus Infinity's design stands out primarily for its rotated socket area and top DRAM slots. The left VRM area features a unique heatsink with a plastic cover that slides open to install 8-pin EPS connectors, and slides closed to cover them. On top is the Aorus Falcon, representing the brand, and it's backlit by RGB lighting from below. Where you’d normally find the top M.2 socket (below the CPU socket) is now populated with VRMs, and the M.2 is to the right, running vertically where the DRAM slots normally are. In essence, the entire socket area primary M.2 socket and DRAM slots are rotated 90 degrees counterclockwise.

The bottom portion of the board uses reinforced PCIe slots and plate-style heatsinks with DIY-friendly features like PCIe EZ Latch Up (which works similarly to Asus’ method they had to change) and EZ Latch Plus/Click for screwless M.2 mounting. Overall, it’s a good-looking board that looks good inside any dark chassis.

Starting our tour in the top left, we get a better look at the sliding cover on the large, heatpipe-connected (big 8mm heatpipes) heatsinks. The smoked plastic piece on top slides down to allow access to the two 8-pin EPS connectors (one required). Connect the leads from the power supply, then slide the piece up to hide the unsightly wires. The only RGB element on the board is the Aorus Falcon flying high on the VRM heatsink, with RGB lighting radiating a frosted glow from below.

The two DRAM slots on top of the board have locking mechanisms on both sides. Gigabyte lists support up to an incredible 9600 MT/s and has/had a record on this board reaching an insane 11,400 MT/s (surely that’s achieved with cherry-picked processors and RAM kits) with heavy manual tweaking. Still, it is possible. In a nod to how well this dual-DIMM-slot board handles RAM, it’s one of the rare motherboards that lets our Ryzen 9 9900X run our Klevv DDR5-8000 kit. Normally, that’s only reserved for the APU and its superior IMC or other (but not all) two-DIMM boards.

Moving past the socket, we hit our first M.2 slot, running vertically where you would normally see RAM slots. It’s also one of two CPU-connected M.2 sockets, both supporting PCIe 5.0 x4 (128 Gbps) speeds and 110mm drives. Above that are two (of eight) 4-pin fan headers, each supporting PWM or DC-controlled devices. The BIOS or Gigabyte Control Center (GCC) controls these headers. Above that are two RGB headers, a 3-pin ARGB (one of three) and a 4-pin RGB header. The RGB Fusion app in GCC controls the integrated RGB feature and anything attached through the headers.

Under the large plate-style heatsink with the Aorus branding are two other M.2 sockets (M2B_CPU and M2D_SB). The top socket, M2B_CPU, as the name implies, connects through the CPU and runs at PCIe 5.0 x4 (128 Gbps). Note that this socket shares bandwidth with the USB4 port. You can run it at PCIe 5.0 x2 (64 Gbps, like PCIe 4.0 x4) or disable the USB4 port altogether for full M.2 bandwidth. This isn't ideal for those who need two PCIe 5.0 x4 drives and USB4, but this split is common across vendors. All M.2 sockets also use Gigabyte’s M.2 EZ-Latch Plus and EZ-Latch Click for easy M.2 installation. For anyone who may want to RAID their M.2s, the board supports RAID01/5/10 modes for NVMe (but RAID5 is only available with Ryzen 9000 series).

Along the right edge, we spot a vertical 8-pin PCIe connector that, when used, supports up to QC-USB 65W charging on the front panel (Type-C port). Below that are the front-panel USB 3.2 Gen 2x2 (20 Gbps) Type-C connector and the board's ATX power connector. Just behind the ATX connector are two 2-pin temperature headers for the two included thermistors. Below the ATX connector are the four SATA ports (supports RAID0/1/10).

Below that are five LEDs: four used for debugging during POST (CPU, VGA, DRAM, Boot), and an additional LED (orange) is for storage activity. We’ve also included several images of the board’s active IC’s. Gigabyte uses a mix of Infineon (PWM controller and MOSFETs) and Realtek (audio, USB, USB4, LAN, etc.).
