hi there, i just upgrade my board from z690 hero in z790 hero. just upgrade a board all whole left i use my old pheriperal when it still in use at z690 hero
got a few problem now
1. if i shut down the pc and start it again, pc keep fail too boot and q code 55 show up
restart pc no affect. pc can restart normally. only when shut down and want to turn it on again q code 55 come out
when q code 55 and screen blank i force shut down by pressing power button. ater that show notify about instabillity and must entering bios
but can boot after that.

2. ram at slot A2 sometimes just not detected by motherboard (system only read 16gb) and ram at slot A2 cant sync rgb at armoury crate
3. cant tuning case fan speed via fanxpert4, at z690 hero i can tune fan speed there. at z790 hero fan just run max speed all whole time
4. also sometimes got usb error at device manager - set address fail. this also happen at z690 hero
what i do until now:
1. reseat cpu, reseat cpu cooler. reseat ram. try to change position between ram - problem still persist
2. downgrade bios version from 0816 into 0813 (same problem). i try to donwgrade into 0703 but cant, because ez flash file cant read
wehen board first come bios ver was 0703. but after installing windows i just update me and bios ver. soo dont know 0703 have same issue or not.
3. if xmp off, after shut down pc can boot normaly
4. still not try gaming until now
1. it only bios issue or something wrong with my board?
because my ram run fine with z690 hero lastest bios
