This is good news! So you're completely stable with XMP enabled? Any crashes since you posted this?
can u test this and see if it solves issue?
Just an FYI to those having this issue. My first Z490-I would freeze when installing windows when there were two stick of RAM installed. I RMA'ed this board and promptly bought a second board, that board had random freezing issues that got much worse when XMP I or II was enabled. ASUS replaced the first board and I swapped it out today and it was able to pass the XTU stress test with XMP I enabled. Will be RMA'ing the second board as well.
My Z490-I has this issue as well. The BIOS shared in this thread didn't help, and ASUS advised me to return the motherboard to the retailer. Can we please get an update from the engineers that are looking into it?
