IOMMU (AMD-Vi) not detected – Alienware Aurora Ryzen 9 5900 – FACEIT Anti-Cheat issue

Hello everyone,

I’m running into a problem with my Alienware Aurora desktop (Ryzen 9 5900, RTX 3080, BIOS version 2.8.0) and I’m hoping someone here might know if there’s a solution.

I’m trying to use FACEIT Anti-Cheat, which requires IOMMU (AMD-Vi) to be enabled and detected at boot. My BIOS, however, does not expose any option for IOMMU or AMD-Vi, only the standard “Virtualization (SVM)” setting, which I’ve already enabled.

What I’ve done so far:

  • Enabled SVM / Virtualization in BIOS

  • Checked for updates, and it seems I have the latest available BIOS driver (2.8.0)

  • Contacted FACEIT support (they confirmed IOMMU must be active and initialized early at boot, and asked me to confirm this with Dell)

My question is:

  • Does anyone know if IOMMU is enabled by default on this model even though the option isn’t visible?

  • Is there a hidden setting, firmware update, or method to confirm that AMD-Vi is being initialized?

  • Has anyone successfully run FACEIT Anti-Cheat on this same system?

Any help or insight from Dell engineers or others would be greatly appreciated 

Thanks in advance,

Verify under Windows:

  1. Press Windows Key + R, type msinfo32, and press Enter.
  2. In the System Information window, expand “System Summary.”
  3. Look for “Virtualization.” It should indicate “Virtualization Enabled in Firmware.”
  4. More specifically for VT-d, you might need to look under “Components” -> “System Devices” or similar sections, although direct confirmation in msinfo32 for VT-d itself can be subtle.

If it's not enabled and not exposed under the BIOS menu as a setting, I am afraid you will be out of luck.

Hi,

I have the same configuration and the same issue. The Dell support escalated this issue three times and the final answer was that it will be pass over to engineers and maybe they will issue an update. Unfortunately, IOUMM is disabled by default by Alienware and there is no way to enable it, unless Dell turns it on via a BIOS update.

I'll never buy their product ever again because of such things. We buy gaming desktop to play games, but we can't because some features are disabled (which all other manufacturers have enabled).
