Socket AM5 DDR5 platform

The GIGABYTE B850 AORUS STEALTH ICE is an ATX motherboard built for AMD Ryzen 9000, 8000 and 7000 series processors. It targets builders who want a clean white aesthetic with modern connectivity and strong overclocking headroom.

256 GB DDR5 capacity with 8200 MT/s OC headroom

Four 288-pin slots support dual-channel DDR5 up to 256 GB. AMD EXPO profiles and manual tuning can push memory to 8200 MT/s. Two SATA 6 Gb/s ports handle legacy drives while one CPU-linked M.2 slot runs at PCIe 5.0 x4 for the fastest SSDs.

PCIe 5.0 graphics slot plus Wi-Fi 7 and 5 GbE LAN

The primary PCIe 5.0 x16 slot connects directly to the CPU for high-bandwidth GPUs. A second x16 slot runs at PCIe 4.0 x4 and shares bandwidth with an M.2 connector. Rear I/O includes HDMI, USB 3.2 Gen 2 Type-C, four USB 3.2 Gen 1, four USB 2.0, 5 GbE RJ-45, Wi-Fi 7 and Bluetooth 5.4. EZ-Latch releases simplify GPU and M.2 installation.
