Had the same issue and found the solution from a user that also had the exact same issue with the ram:

The following settings solved his issue:
- Enable XMP
- Set DRAM voltage manually to 1.35V
- Set RAM multiplier to 32x
- Set the first five subtimings manually to 16-18-18-18-36 (the same as XMP would) (important!)
- Set the sixth timing (tRC) to 56 instead of 54 as XMP would (important!)

Tested on the latest GB BIOS f10c.

So the issue is with the XMP profile not being read properly. Only when activiating XMP and making the above changes in the BIOS the system runs stable.

It may be due to Gigabyte BIOS or AGESA related features that regulate the timings on the Ryzen platform, maybe even Ryzen's internal memory controller.
 

Good day to you. 
I also had this problem. While i was still attending school, i had a lot of free time. I would use that free time by gaming, and boy i gamed a lot. I used to play game like Dota 2,LoL, CS:GO and other competitive games. I also enjoyed single player game with a rich story, like the witcher, dishonored etc.
Then came work. And with work everything changed for me. Since i work for 8 hours a day, and i also have some other hobbies i didn't have enough time to do everything at the same time. So i had to cross some things out, the obvious one was gaming, because for competitive games you need to stay active in order to be good, and while working that is not happening. 
But after some time i started to miss gaming a lot. I tried browsing through steam, but the new games seemed like trash. Then i decided to buy a ps4 since it is more for casual people. Really wanted to play bloodbourne. But before playing bloodbourne i started with Dark souls, and suddenly it caught me. I was soooo into Dark souls. I wanted to try out other games but i really suck with controllers, so the choice was obvious. Build a new pc. 
After doing that, i started to play more and more often, i think i needed a break of gaming, but i kinda always knew that i would game again. I guess i just needed to try a new (well dark souls is not exactly new) game, that could catch me and prove it that there are indeed games that are worth playing. 
By writing this i hope that you will maybe try out different games, buying a ps4 is not a bad idea, because you'll play god of war and after that game you might be thirsty for other games
I really recommend competitive games as well, at least for me, they are the least boring, because you actually need to get better at them, and when you rank up by defeating other players, you have this weird nice feeling haha.
