Kurkoko Posted February 6, 2021 Share Posted February 6, 2021 Hello, Just moved all my Gaming PC to work as unRaid. All is working but have iommu group issues I expected good iommu groups with this motheboard but found that 1st and 2nd PCIE16x (i know when both are populated are 8x8x) are in the same IOMMU group. Need help from someone using maybe any variation of Aorus Z390 just to know bios version or if have the same porblem. Im on the latest one F11n i think. Best regards Quote Link to comment
Squid Posted February 7, 2021 Share Posted February 7, 2021 Try one of the ACS override options. I would think that by and large the PCIe's coming off of the CPU instead of the chipset will always wind up in the same group without ACS Quote Link to comment
Kurkoko Posted February 7, 2021 Author Share Posted February 7, 2021 I wanted not to use ACS becouse as far as I know it comes with performance penalty hope someone have similar to know if old bios have better iommu groups Quote Link to comment
