ASUS ROG Crosshair X870E APEX - Extreme Overclocking Motherboard

The ROG Crosshair X870E APEX is engineered for enthusiasts who demand world-record overclocking performance on the AMD AM5 platform. Built around the AMD X870E chipset, this ATX motherboard combines 18+2+2 power stages with advanced cooling solutions to push AMD Ryzen 9000, 8000, and 7000 series processors beyond their limits.

DDR5 Memory Performance

Featuring dual DDR5 DIMM slots with NitroPath DRAM Technology, this motherboard achieves speeds exceeding 9 GT/s with Ryzen 9000 series CPUs. The included ROG Memory Fan Kit provides active cooling for extreme DDR5 overclocking, while ASUS Enhanced Memory Profile (AEMP) and DIMM Fit Pro optimize individual memory modules for peak performance. Maximum capacity reaches 128GB with support for AMD EXPO profiles.

PCIe 5.0 and Storage Expansion

Three onboard M.2 slots support PCIe 5.0 x4 connectivity for next-generation SSDs, with the unique ROG DIMM.2 expansion card adding two PCIe 4.0 M.2 slots. All M.2 installations utilize tool-free Q-Latch and Q-Slide mechanisms. Two PCIe 5.0 x16 SafeSlots with Q-Release Slim technology accommodate the latest graphics cards without manual latch manipulation.

Connectivity and Networking

Dual USB4 ports deliver 40Gbps bandwidth with DisplayPort Alt Mode support. The rear I/O includes six USB 10Gbps ports and two USB 5Gbps connections. Wi-Fi 7 (802.11be) with the included Q-Antenna supports 320MHz channels across 2.4/5/6GHz bands, achieving speeds up to 6.5Gbps. Realtek 5Gb Ethernet provides wired connectivity with AI Networking II optimization.

Advanced Power Delivery

Front-panel USB 20Gbps Type-C ports feature Quick Charge 4+ with up to 60W Power Delivery and USB Wattage Watcher monitoring. The 18+2+2 power stage design with dual 8-pin CPU connectors and an 8-pin PCIe connector ensures stable power delivery during extreme overclocking sessions.

AI and BIOS Features

Dynamic OC Switcher automatically alternates between manual overclocking and Precision Boost Overdrive based on workload. Core Flex provides granular control over individual core frequencies, power limits, and thermal thresholds. The asynchronous clock generator isolates CPU base clock from memory and PCIe speeds. BIOS Q-Dashboard simplifies configuration with visual hardware representation, while AI Cooling II balances thermals and acoustics automatically.

Audio and RGB

ROG SupremeFX audio with ALC4080 codec delivers 32-bit/384kHz playback through a Savitech amplifier capable of driving high-impedance headphones. Aura Sync RGB lighting synchronizes with compatible peripherals through addressable Gen2 headers and an 80-LED light bar connector.
