Slim Specs Table

Compact Micro-ATX with Full AM5 Power

Built on AMD’s B850 chipset, this Micro-ATX board supports the latest Ryzen 9000, 8000, and 7000 series processors. Its 8+1+1 Dr.MOS power stage delivers clean, stable power for demanding workloads, while the pre-installed I/O shield saves installation time. The 9.6″ x 9.6″ footprint fits small cases without sacrificing PCIe 5.0 graphics and M.2 performance.

Dual-Channel DDR5 for Responsive Multitasking

Four DDR5 DIMM slots support up to 256 GB of memory at speeds up to 8000+ MT/s (overclocked). Dual-channel architecture improves bandwidth for content creation, 3D rendering, and multitasking. XMP/EXPO profiles enable instant memory overclocking, and ECC support adds data integrity for workstation use.

Blazing Storage: PCIe 5.0 + Gen4 M.2

One M.2 socket runs PCIe 5.0 x4 (up to 128 GB/s) for ultra-fast NVMe SSDs, while a second supports PCIe 4.0 x4 (up to 64 GB/s). Four SATA 6 Gb/s ports handle additional drives. Combined with RAID 0/1/10 support, this setup offers flexible, high-throughput storage configurations for games, media, and professional projects.

Wi-Fi 7 + 2.5GbE for Ultrafast Networking

802.11be Wi-Fi 7 delivers higher throughput and lower latency than Wi-Fi 6, ideal for streaming, cloud gaming, and remote collaboration. The 2.5GbE Dragon LAN port ensures reliable wired speeds, with software for bandwidth control, visual usage stats, and preset modes for gaming, browsing, and streaming.

ASRock EZ Update & Troubleshooting Tools

BIOS Flashback allows firmware updates without a CPU installed. ASRock Auto Driver Installer simplifies software setup, while Full HD UEFI provides an intuitive interface for tuning. RGB LED and addressable headers support ASRock Polychrome SYNC for coordinated lighting effects.
