"Asus support says that the RAM I am using is not on the Z690 Hero "approved list" which is nuts because I received that RAM and Mobo from a Newegg combo! The agent linked me the list and sure enough that CAS 36 version of the GSkill Z5 6000 is not on that list! I asked him why it would have 0 issues getting to the BIOS last night etc and he said that it can work for awhile and then stop working all together.'
