Best post ever.

BUFUMAN Looks like i said it. We will be beta tester again. The amount of time some of us invested in AMD is not worth it. It took me up to 4 Months on Ryzen 1700x to boot stable (cold) this is something i can't accept. You can buy 2 or 3 Intel CPUs if you calculate the worktime....

The System has to boot!

The reputation, and respect has gone.
And Remember Respect is everything ^^
My advice to every person who can send this crap (Mainboard) back, do it right now. Kick it into Asus face. They sh** on us we sh** back.

Tell us the solution?

Mhh, maybe you are right. I once again removed the offset and did some more testing. That high temperature also only shows up when running p95 small fft. But it will not exceed 92°C at about 4040 MHz all core. When running p95 blend, temperature is about 75°C at about 4130 MHz all core. I will stick with auto settings for now.

Adding an -0.2v offset reduces both temps and performance dramatically. Only about 6300 points in CB.

Adding -0.1v seems to be ok. CB performance is down to about 7075 points with temps about 10°C less than with auto. Allcore frequency is about 25 MHz less on each core. I am currently running prime95 for 30min and allcore freq is constantly about 4033 MHz per core. Temperature is about 81.5°C

So with the Noctua NH-D15 beeing pushed to it's limits with auto vcore enabled, how should the stock cooler work/perform? I just can't image that this is the way AMD designed that thing. Must be an issue with the bios. Or maybe AGESA 1.0.0.3 is the key to lower temps?

jstar Today was final attempt before sending C6H back, MB was on test bench and outside case.
In this video connected was:
ATX 24 pin
CPU 8pin
GPU with 2x PCI-e power
1x MEM

CPU (1700 or 3700X) and cpu+some case fans (flapping sound)

Here is first successful POST with Ryzen 1700:

And here is 3700X, the only thing what has changed is that system was turned off, CPU swapped to 3700X:

I still have a week to return my 3900X, I will give Asus until this weekend to get a new bios before I have to return the chip. I don’t think a board RMA will fly for me as the 3900X is not a supported chip (officially).

If I do have to return it, I may wait a month or so and try again with a 3800X after BIOS matures.

This is painful, since I bought first gen Ryzen years ago to get an AM4 board, specifically waiting for this day. I could have bought intel and been gaming at higher FPS for the last 2 years, but I bought into AM4 for the forward compatibility and to support AMD (competition is good). Frustrated!
Indeed... and the lack of communication is what makes it the worst. If Asus would say that there has been unexpected issues what we haven't noticed, give us until <date> and we'll provide ETA for fix then. Then we would at least know, because you go crazy with troubleshooting, settings etc because with the same rev, exact same components, people have been able to put their system working so there is small doubt always what if, what if, what if ... but I am glad I still had my old CPU and when everything works with that, I know it must be 3rd gen.

I did return board today, let's see how it goes. Extremely frustrated as well, I specifically went for 3rd gen / AM4 to avoid what I did today; unscrewing MB fron chassis, unplugging every single cable, detaching all my carefully and thought cables, they were ziptied, ... sigh.

running 2 kit of G.Skill Trident Z 2x8GB DDR4-3000 CL14 - F4-3000C14D-16GTZ - 32gb total.
my 3900x is running fine on 7106 and 7201. 7201 did fix the mouse issue in bios.
