Yes, I did.
All tests are ok. CPU, RAM, hdd. Latest BIOS for main board Asus M5A99X EVO R2.0 too.
I even did a GPU stress test in FurMark for 30 mins. max temp was 60 and the driver was stable all this time.
That's a bummer..
There isn't any fix for this.
It's a problem that happens with almost every RX400 series cards. They never fixed it in any driver. There is already many topics here, on reddit, and other big forums about this problem and AMD keep ignoring it.
My RX480 does the same, and I have other friends with RX480's doing exactly the same, even on new systems.
