AM5 · X870E · ATX · DDR5
The GIGABYTE X870E AORUS Master is a flagship ATX motherboard built on the X870E chipset for AMD Ryzen 7000/9000 processors. With 20+2+1 power stages, 4x M.2 slots, and DDR5 support up to 128GB, it targets enthusiasts and power users who demand premium features and rock-solid reliability.
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. Check GIGABYTE's security page and this board's own support page, 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.
