I just loaded a 2nd generation Threadripper into a motherboard, and got this same error.? Using BIOS Flashback, I updated to the latest and all is working.??


I received this code too. Downloaded latest Bios. Used BIOS Flashback function with BIOS on USB. Bingo, it boots.

I really didn't think a BIOS update would be necessary but it was.

I could have sworn at one point I too had a C0. Mine is because I had one faulty DIMM that eventually I found a slot and a good seating for.

Just FYI I had that C0 error also with an MSI board and in the end it turned out to be a faulty DIMM slot. What happened was I put in 4x16GB and the bios saw 4x16GB sticks installed in the slots, but the system only saw 48GB of memory available.  I then tried 2 sticks and also got half memory, so I put in one stick C0 error, changed the stick to the other one in the same slot and got a C0 error. So try putting in 2 sticks, if you can get into the bios and it reads half the total memory then it's probably a bad dimm slot.

And the PSU.

Okay, so I got a new TR and still get the C0.
Could someone from AS Rock please tell me what C0 means and what I could possibly do?

Leaving the setup powered for a while leaves it in the boot loop (every time rebooting after 15 seconds with C0), after a few cycles the mobo shuts down completely, the CPU is quite hot...

I have no further idea, so the only two things left to check is the PSU (no idea how to check if it may be faulty) and the CPU. I guess I just have to get a new TR.


Test each memory stick individually in every DIMM bank, its quite possible this could be the source of your problems as well as ruling out an iffy DIMM bank.
