I have a question, I've got DSI motherboard and IOMMU and Above 4G decoding is on. It works. What are the downsides of keeping Above 4G active?Oh yes that's right. I forgot to mention that there are a couple of bios settings that need to be set on the DSI for the ZS cpu's, it's finicky. So turn on IOMMU and disable Above 4G decoding and it should work
