Overview
The ASUS ROG Crosshair VIII Dark Hero is a high-end ATX motherboard built on the X570 chipset for AMD Ryzen 5000/3000 processors. With 16+2 power stages, 2x M.2 slots, and DDR4 support up to 128GB, it targets enthusiasts and power users who demand premium features and rock-solid reliability.
Security advisory: check your BIOS
AMD published bulletin AMD-SB-7064 on 11 August 2026. It covers two high-severity flaws in AMD's firmware TPM: CVE-2026-6726, an information-leakage flaw that lets a forged TPM key be certified as genuine, and CVE-2026-6727, a timing side-channel. AMD scores them 8.5 and 8.3 on CVSS 4.0. Affected processors run from Ryzen 3000 to Ryzen 9000, plus Threadripper, Ryzen AI and Ryzen Embedded parts. Both attacks need local privileged access, so neither is remotely exploitable. The underlying flaw is in the Trusted Computing Group's TPM 2.0 reference code, which AMD ships as fTPM.
The fix arrives as a motherboard BIOS update. Windows Update will not install it. Find this board in ASUS's Download Center, open Driver & Tools and then BIOS & Firmware, install the latest BIOS, then look for an fTPM or TPM security fix in the release notes. Coverage varies by board, and we have not verified that a fixed BIOS exists for this one.
Before you flash: if this machine uses BitLocker, save your recovery key first. A firmware update can trigger BitLocker recovery, and Windows will then ask for a 48-digit key before it unlocks the drive. Our BIOS update guide covers the safe order.

Pros & Cons
Pros
- Strong 16+2 power delivery for reliable performance
- 2.5 Gigabit Ethernet for high-speed wired networking
Cons
- DDR4 memory limits future upgrade path to DDR5
- No PCIe 5.0 GPU slot — not ideal if you want maximum future bandwidth
Who Should Buy This Board?
Gamers and creators who want premium features without flagship pricing. A great choice for high-end AMD Ryzen 5000/3000 builds that prioritize connectivity, storage expansion, and solid power delivery for sustained loads.
Build Tips & Recommendations
- AM4 has excellent cooler compatibility. Nearly every tower cooler and AIO supports this socket out of the box.
- DDR4-3600 CL16 is the optimal speed for this platform. Enable XMP/DOCP in BIOS to ensure your RAM runs at its rated frequency.
- Install your primary NVMe SSD in the top M.2 slot closest to the CPU socket for the fastest connection. The 2x M.2 configuration is sufficient for most builds.
- Any standard ATX mid-tower or full-tower case will work. Ensure your case has sufficient fan mounting points and front panel USB headers that match this board's internal connectors.
- Always update to the latest BIOS before installing components for the best compatibility, especially with newer CPUs and RAM kits. Download the BIOS file to a USB drive and use the flashback feature if available.
