RX 570 and the Asrock 970 Pro 3 (R2.0)

I want to know directly from Asrock if there are any compatibility issues with a non-reference RX 570 (from XFX) and the 970 Pro 3 motherboard.

I recently got this card several weeks ago. Upon successfully installing the card and thoroughly cleaning my hard-drive from the previous card's drivers, I notice that games crash after 30 to 40 minutes of gameplay. Now, this did not happen on my previous card which was a measly GTX 750ti, but I do notice that games or sometimes the entire computer crashes with RX 570. However, it is worth noting that my computer can stay on for a very long time doing tasks that doesn't stress my RX 570, like web browsing, watching 1080p MKV's at H264 encoding, programming on an IDE, or even using 3D modeling software like Unity or UE4.

Now I have confirmed that this is not a driver issue. I fell back to Crimson ReLive 17.7.1 which is currently the most stable version available from AMD until they get their act together.

So is there any PCI-E incompatibilities going on? If so, is there anything I can do in my power to fix it? Really don't want my new card crapping out after 20 minutes of playing Dark Souls 3.

My signature has my specs in it, which is surprising that the OP does not show it but this post does.

I only got the PSU because I heard good things about it. Aside from that, my PSU should be more than enough to power the card and my entire system.
