IOMMU is a powerful hardware security feature, which is used to protect your machine from malicious software as well as helping guarantee the integrity of matches protected by FACEIT Anti-cheat.
We are rolling out IOMMU as a requirement progressively, and recommend turning this feature on in BIOS if you haven’t already done so. If you are now required to activate IOMMU and haven’t done so, an error message will pop up when launching the FACEIT Anti-cheat. To remove it and get back on the server, make sure to read the sections of this article that are relevant to you!
We've published the final rollout schedule with more details about why we are requiring this in order to improve protection against cheats across matchmaking and official matches on FACEIT.
⚠️Any changes to your BIOS are made at your own risk, we are not responsible for any issues with your PC. If you are not familiar with making changes in your BIOS we recommend contacting a professional.
🖥️ Identify Your CPU and Motherboard Brand
No matter your build, the first step is inevitably to understand which hardware you are using, in order to perform the right changes. You can find this information using the System Information tool (msinfo32):
- Press the Windows key.
- Type msinfo32 and press Enter.
- Look for Processor and BaseBoard Manufacturer/Model.
🔧 BIOS Settings Overview
To enable IOMMU, you will need to perform a specific set of steps tailored to your build, as your BIOS settings vary by motherboard and CPU model - make sure these have all been updated to the latest versions! To find how to enable IOMMU, we recommend searching online for:
“How to enable IOMMU on [your motherboard model]”
or visit your motherboard manufacturer’s website for specific instructions.
We’ve also included a set of instructions for the most common setups below - make sure you’ve identified which section applies to you, and follow the instructions!
