Hello,
I have a new Crosshair VI Extreme board with a Ryzen 1800x CPU and I have stumbled into 2 problems. I have tried to solve the second problem through a BIOS update which failed and created problem #1.
Problem #1
I have tried updating BIOS with ASUS EZ Flash. Selected Internet, DHCP; BIOS downloaded without problems but then the update process started and during the beginning phase of it the board suddenly restarted.
Now the board does not boot up properly: the graphics card stays blank (black screen), Q-CODE shows error "4b" and the Q-LED DRAM is lit. The CPU cooler (H80i v2) does not even start.
I have Corsair CMU16GX4M2C3200C16R memory and it worked fine at 3200 MHz prior to the BIOS update. I have tried removing and reinserting it but the problem prevails.
I have tried flashbacking the BIOS per instructions here:

If I start the system with removed DRAM everything stays the same but the Q-CODE changes to error "4b" again. After reinstalling DRAM Q-CODE shows error "07".
Seems my BIOS is damaged or is the board faulty? How do I proceed to restore a working BIOS?
Problem #2
I have a Ryzen 1800x cpu and thus it reports 20 degrees celsius more. With a Corsair H80i v2 cooler I get cca. a 80 degree celsius reading in BIOS so the CPU should be running at 60 degrees celsius. I suppose this is acceptable until the thermal material breaks in.
The problem is that at boot time I get a "cpu over temperature error press f1 to run setup" message. How do I proceed with booting the system, I seem to only be able to go to BIOS from here. I was hoping that a BIOS update would solve this issue but stumbled into problem #1
