forgot today is chap goh meh etc
asus china on holiday
so have to wait more for that new bios

busta no that is error thats related with voltage
test memtest hci for a hour or so in diagnostic mode
i had the same issue with uncore 4000 and came with the same conclusion
until i failed memtest hci 3000% something
and then started messing around with ioh/ich voltage to find the right combo with the vtt.
and never appeared after that.
