GTR 9 Pro IOMMU bios options

DrDre

Hey @Beelink CS-George . I noticed that when disabling IOMMU under OS options, we get a measurable performance increase, about 6-12%. Currently the option to disable IOMMU in bios is grayed out, is there a reason for that?

(NOTE: for readers of this post, IOMMU is necessary for virtualization and VMs. If you’re making use of these features then you can’t disable.)

Hello there,

Please press delete key as soon as you turn on the PC, so that you can go to BIOS. Please send us a picture of the Main page.
We will check if you need to update the BIOS.

Please repeatedly press delete key as soon as you turn on the PC, go to BIOS. On Save&Exit page, please click Restore defaults, press enter to confirm, then press F4 to save.

@Beelink CS-George The bios version is the latest Image description
As can be seen below, the bios IOMMU setting is set to auto without option to change:

I would upload higher resolution images but we’re limited to 120kb in the forum
