	Do you have both the four pin and eight pin ATX 12V CPU power connectors on the board connected to the PSU? Both of these connectors must have a cable from the PSU attached or the CPU will not start. C0 is called by AMI a "OEM BDS initialization code", which means it is a very early failure in the POST process, which makes me think you don't have both of those power cables connected, but I may be wrong. Besides the PSU and CPU, we have no idea what other components you are using.

	Tried other DDR4 ram, still no joy... I'm at a bit of a loss here, I'm kinda thinking its going to be an RMA job... but why do they have Fault Codes for motherboards that then they don't even list... First time buying an ASROCK and yeah not a good experience so far...

	Heya!! Just built a 1950X on a X399 Taichi The Build went sweet with no real issues, ran my water loop for a good 18 hours with no leaks etc... I went to turn on the PC and i am getting a C0 fault. I have re-seated the ram (which was already in perfectly) I have taken the CPU cooler off and lifted the CPU up again and double checked the pins which were all fine... I have an AX1200i and have checked connections which are all fully seated in their respected sockets I am considering a bios flash using the BIOS Flashback option. I have downloaded the Instant Flash rom from the website and have been looking for a reference as to a file name. I'm probably going to go put it in now to see if it works. Does anyone else have any further suggestions from this point ? Oxijex
