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 ?

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...

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.

Hi Parsec,

At that point in time all i had was the ram installed and the 1950X and the AX1200i connected. I didn't see the point in listing any further components due to already having had removed them to try and fault find :(

Ok so, for some reason... it started working...

I took the Cmos battery out... removed the cpu for the 10th time and replaced it... started it with only the ram and then i got GPU code.. so put GPU in and got BIOS... the m2 was a bit dicky but it worked in slot 3.... anyway... can't really say what it's issue was.. It's working now.. From such a really cool way to install a CPU it turned into a nightmare build :(

what parsec was sort of asking
was for you to help us help you

specific to your issue was the question about your power supply

make and power and model

we had a chap the other day stuck with an x399 it turned out he had the wrong type of leads on his power supply and hadnt connected them correctly

hence why people here ask for details of your system so we can help you better

anyway i know it has started now but lets make sure this problem dosnt happen again

are you aware with the x399 you need a power supply with TWO eps/cpu leads as well as the normal 24 pin ?

if your dosnt or one is not connected this may be giving you these errors

Hi Datonyb

All i got from Parsec was that he didn't read my original post, I listed what i had done, while cryptic from my message you can gather that i am running a

X399 Taichi
1950X
AX1200i - Corsair AX1200I 1200W power supply

I do appreciate your feedback, but if you have people coming on here asking for assistance in building a PC then they shouldn't be building one. I am on here because i have fault codes for seemingly no reason. I would have rathered RMA the board but it seems after flashing the bios 7 times and reseating the cpu 6 times the thing decided to work.

When i made my post i was really looking for 

"A C0 Motherboard fault often relates to this" 

I have never had a build fail so much and to be honest being the man i am, i will blame ASROCK and AMD.... and i'm pretty dissapointed with the forums. I gave a decent slot of information from the start to then be provided with "Need more information about system" *No you don't i told you the simple components that i was using to still recieve the fault* "are you aware with the x399 you need a powersupply with TWO eps/cpu leads as well as the normal 24 pin ?" *Dude do you know what an AX1200i is ????*
