Used Ryzen 7 5800X3D Was Blocked From Valorant by Vanguard

Vanguard blocked a previously used CPU

A gamer from Germany reported that a used AMD Ryzen 7 5800X3D worked normally in their computer but triggered an immediate Valorant ban when they launched the game. The player shared the problem on Reddit and contacted Riot Games for support.

Riot support traced the restriction to the processor's hardware ID. According to the gamer, the CPU had been purchased on September 21, 2026, but Vanguard had placed it on its denylist on August 12, 2026 because the previous user apparently cheated in Valorant. Support said the ban could not be reversed and seemed to affect the buyer's Valorant account.

The buyer said the restriction was not a major issue for them, but also claimed that other components in their system had been blocked. That impression was later disputed by Riot Games.

Riot clarified the hardware ban rules

After the story spread on X, Riot Games anti-cheat specialist Phillip Koskinas said hardware bans last for a maximum of four months and are specific to the game in which they were issued. He also said customer support can tell players how much time remains on their ban.

Koskinas said Vanguard matches only one component on its denylist, rather than adding every part of the offending player's computer. The Ryzen 7 5800X3D owner could therefore play Valorant again after the restriction expired.

Hardware ID policies differ across anti-cheat systems

Other games and developers use different approaches to hardware ID enforcement. Easy Anti-Cheat bans cheaters and users with affected hardware across games using the system, while BattlEye enforces permanent global bans. Vanguard requires Secure Boot and TPM 2.0. Ricochet, the anti-cheat system used by Call of Duty, contacts Microsoft's servers to check whether a system remains untampered.

Anti-cheat systems have faced criticism for being intrusive and resource-intensive. One Valorant anti-cheat update also soft-bricked purpose-built cheating hardware, alarming some players. However, the source notes that such systems remain important for reducing cheating, trolling and griefing in online games.

The case highlights the risk faced by buyers of used CPUs and GPUs. Hardware may retain a restriction associated with a previous owner, and buyers may have no practical way to check its status before trying to use it in a game.
