I have the same problem with my GSKILL 7600 Kit. Also a Hero Z790 Board.
I am not able to load any XMP profiles. Also 6400 is not booting. I have tried the BIOS 0703 from today (I guess)
Is that a error from the Board or can this be fixed from BIOS side? I have only 3 days time left to be able to give back my board to the Shop.
My ME Version is 1825. Is that an issue to run an older ME Version? I getting also a n error when I want to use the MEUpdateTool. Please see picture attached. Where can I find the latest MEupdateTool for my Z790 Hero Board?
Thank you very much
Just cancelled my Z790 Apex pre-order at Newegg. 😞
