Overview
The GIGABYTE B850 Aorus Stealth ICE is a full-size ATX gaming motherboard built on the AMD B850 chipset, designed for AMD Socket AM5 processors including the Ryzen 9000, Ryzen 8000, and Ryzen 7000 series. Its clean white aesthetic and STEALTH-series design philosophy prioritise broad chassis compatibility, making it a versatile choice for DIY builders who want a cohesive, minimalist white build. Power delivery centres on a digital twin 14+2+2 phase VRM solution, reinforced by VRM Thermal Armor Advanced heatsinks that maintain stable CPU voltages even under sustained multi-core workloads. GIGABYTE's X3D Turbo Mode BIOS feature applies dedicated optimisation parameters that can raise gaming frame rates on Ryzen 9000-series processors, including non-X3D variants, by tuning cache and latency settings at the firmware level. Memory support spans four DDR5 DIMM slots in a dual-channel configuration, accommodating up to 256 GB (with 64 GB single-DIMM modules) at speeds from 4400 MT/s up to 8200 MT/s via overclocking. Both AMD EXPO and Intel XMP memory profiles are supported, simplifying one-click memory tuning in the AMI UEFI BIOS. Storage options are expansive: four M.2 slots (including one PCIe 5.0 x4 CPU-connected slot capable of next-generation NVMe speeds) plus two SATA 6 Gb/s ports. RAID 0, 1, 5, and 10 are available for NVMe devices (RAID 5 requires a Ryzen 9000 processor), while SATA supports RAID 0 and RAID 1. The EZ-Latch Plus and EZ-Latch Click mechanisms allow tool-free M.2 and PCIe card installation. Connectivity is handled by a Realtek Wi-Fi 7 (RTL8922AE) module covering 2.4 GHz, 5 GHz, and 6 GHz bands with 160 MHz channel support and Bluetooth 5.4, alongside a Realtek 5GbE wired LAN port. The back panel provides one USB Type-C (USB 3.2 Gen 2), two USB 3.2 Gen 2 Type-A, four USB 3.2 Gen 1, four USB 2.0 ports, HDMI 2.1 output (up to 4096×2160 @ 60 Hz for iGPU use), optical S/PDIF out, and dual audio jacks. Onboard audio is powered by the Realtek ALC1220 codec with 7.1-channel HD Audio support. RGB lighting is managed through three addressable RGB Gen2 headers and one standard RGB header, with full control available via GIGABYTE Control Center software. Q-Flash Plus enables BIOS updates without a CPU or memory installed.
