GoKawiilUsed Ryzen CPU triggers Valorant hardware ban from previous owner's cheating
A German gamer bought a secondhand AMD Ryzen 7 5800X3D and was banned from Valorant because Riot's Vanguard anti-cheat had blacklisted the chip's hardware ID in August 2026 over a prior owner's cheating. Riot support told the buyer the ban couldn't be reversed, though Riot anti-cheat specialist Phillip Koskinas later clarified on X that such hardware bans are game-specific and last a maximum of four months, and that only the flagged component—not the whole PC—gets denylisted.
GoKawiil's interpretation of the reporting above, not reported fact.
The incident highlights a blind spot in the used hardware market: buyers currently have no way to check whether a CPU or other component carries an anti-cheat ban before purchasing it. Riot's response suggests the consequences in this case may be less severe and permanent than first feared, but other anti-cheat systems reportedly impose permanent HWID bans, meaning similar purchases elsewhere could carry greater risk depending on the game and developer.
- Buying a used CPU can inherit an anti-cheat hardware ban tied to its previous owner.
- Riot says Vanguard hardware bans are game-specific and capped at four months, contradicting some user fears of permanent, system-wide blacklisting.
- No existing tool lets buyers check a used component's ban status before purchase, and other anti-cheat systems may enforce permanent bans.
