Guide on B550 Motherboards and DMA Compatibility


Recommended Posts

  • 1. Administrators

A rare issue affects some B550 motherboards, primarily ASUS models, where a security driver flags DMA devices regardless of firmware. This can lead to bans in Easy Anti-Cheat (EAC)-protected games. While most reports involve ASUS boards, a few cases have been noted with other brands, though these are extremely rare.

Other chipsets, like B450 and B650, are completely free of this issue. The problem persists regardless of DMA firmware type, whether Basic (CFW), Premium (Valorant CFW), or Ultimate (Emulated FW).

For a worry-free setup, any other motherboard would be your safest option. If using a B550, especially ASUS, test thoroughly in low-risk scenarios. For most users, this issue is unlikely to occur.
