That suggests to me that it's the PSU shutting down rather than a failure of the VRMs to provide sufficient power to the CPU. Can you measure the power drawn from the supply socket with something like a Kill A Watt meter? If not I'd try a higher powered PSU or a lower powered GPU.
I tried a 650W PSU, but the system still crashes. Also the same PSU (Cirsair SF450) can power this gpu with a comparable cpu (same wattage) on another system just fine. Therefore I do not believe that it is faulty/too weak PSU. Power Draw is between 300 - 350 Watt while benchmarking. Directly at the Wall plug (including Display, keyboard, Soundsystem, etc.). PC only is about 250-300W.

I already did a RMA for the last Board. But maybe the second one is also broken. I will try another Mainboard tomorrow in a PC shop. If it works I will RMA this board and stick to another brand.

In case you hadn't realised, I'm just a customer, like you and everyone else here. I have no affiliation with ASRock, AMD or anyone else. I just use their products and, in general, I'm very happy with them.

That's ok. Advice is offered in good faith in the hope that it will help. Sometimes it does. Sometimes it doesn't. But it's always free. You just need to try to put your frustration to one side because I really don't care whose products you end up with, though I hope you find a combination that works for you.

There's a new non-beta BIOS (P4.50) out today. It might help, though it probably won't.

Hi all.  I'm having a similar problem to OP, other than that when I stress test with CPU and GPU simultaneously, I do NOT have a hard shut down.  I have hard shut downs only while on WoW.  At random times.  The long and torrid story is at the following link:

https://us.battle.net/forums/en/wow/topic/20762267338?page=1

I've tried everything, replaced all components down to the motherboard.  There is a VERY extensive list of things I've tried on the link.  I'm a desperate girl now and about to lose my mind.  I'm curious if the OP ever resolved the issue?  If anyone has any suggestions for me...please...let me know.

I don't see any mention of your BIOS version, I may have missed it with that DXDiag copy paste in there.

I also don't see a power supply make and model listed on your thread, that would be helpful. Some power supplies, even ones rated as 500w+ either lie (state maximum power instead of nominal power) or are what is know as dual rail PSUs (have their power rating split in 2 making them in essence half the rating if only one portion is connected).

Generally, a hard power off is indicative of a power issue. Either the PSU is inadequate or there is a physical short somewhere. It is quite common for there to be an extra mounting standoff under the board that should have been removed and is shorting for example. 

Unfortunately issues like this can be very tricky to pin down. There are so many possible causes that it makes it tough to work out. We are more than happy to help you work through all the steps to getting things working correctly though Wink

First thing to check is that there are no shorts, no screws or misplaced standoffs under the motherboard. It is an annoying job taking things apart to look but if it solves your issue it will be worth it. If it does not, at least we can rule it out and move on. 

If you can also give us your BIOS version and PSU make and model, that would be great too.

Apologies.  That's a super long post.  The info is all in there but buried under an avalanche.

Regarding the physical short:  I've now taken the entire rig apart and put it back together multiple times (twice yesterday).  There are definitely no screws rattling around.  Currently the only things under the board are the 4 standoffs on the corners.

Regarding my PSU:  My PSU originally was an older 750W that I thought was failing, swapped to a 550W that wasn't rated (before I knew better), then most recently I just installed within the last 2 weeks a Corsair CX750 cp-9020015-na  (https://www.amazon.com/Corsair-Bronze-Certified-Non-Modular-CP-9020015-NA/dp/B008RJZQSW) which is a dedicated single +12V rail.  There has been no change in the frequency of my shutdowns between any of those.

I'm on BIOS v 4.6 (posted 4/24/18).

Thanks for the info, that PSU should be fine :)

Are you using the wifi on your board to connect to the internet/network?

You can try downgrading your BIOS to version 3.40, that was the last BIOS that was specifically tuned for Ryzen 1xxx CPUs. The newer ones are to support Ryzen 2xxx CPUs and seem to cause issues for some people using Ryzen 1xxx CPUs. It appears to mostly effect boards with wireless integrated so you definitely fit the bill. I am sure there will be a new BIOS update soon that will be better tuned for both generations but for now, stay away from 4.xx.

Make sure you download the instant flash version from your product page, extract it onto a FAT32 formatted flash drive then use the instant flash option in your UEFI. This is the safest flashing method.

BIOS 3.40 is the one you want. 

Let us know how that goes for you.
