Describe your issue:
After several hours of being essentially idle (web browsing) my monitors will go black or have a single static color, then the system turns off. When I return to Windows, AMD Radeon Settings says that it reset the settings due to an unexpected system crash. The settings are set to the default (balanced profile) and it still occurs randomly. I do not have any problems gaming for several hours at a time (Prey). It appears to happen way more frequently if I have a virtual machine running using VMware Workstation 12. I had no issues before when I was using an XFX RX 460. I ran DDU before installing the latest 17.8.2 drivers. This also occurred on 17.8.1 but I'm not sure about the betas before it. I updated pretty quickly after the official 17.8.1 was available.
I'm not sure if this is a driver issue or if I have a defective card, but it seems like a driver problem since I've never had a system crash during game play.

Added new tested drivers.
So yesterday I decided to turn off "Link State Power Management" as well as change the WattMan profile to "Power Save". It has been a day and no crashes have occurred. I'll need to test some more to see if either of those options did anything.
I too have observed this behavior. However, I have been running my system with Link State Power Management disabled. I have also been running it in Power Save mode since pretty much day 1. I have only observed the issue two times and it only happens to the system sometime after it has waken from sleep. It never happens after a cold boot.
Hmm. I've crashed, rebooted, then crashed again all within 30 minutes before. I never put my system to sleep so that wouldn't be a factor. I'm now testing "Balanced" with "Link State Power Management" disabled. So far no issues but it usually takes several hours. If it doesn't crash all day tomorrow then that is most likely the culprit.
If I had to guess, the issue is related to the following bug.
I've run into this bug several times already. The Event Viewer points it to volmgr. My guess is it it's a driver issue with HBM2 clock timing, HBCC bug despite Radeon settings reported it as disabled, something along those lines. I doubt it's hardware since the card runs fine under full load for hours of testing PUBG, Quake Champions, BF1, FFXIV, etc.
My conclusions thus far:
1. No crashes with power save profile. Gaming or otherwise.
2. Random desktop crashes with the balanced profile, but no crashes when gaming.
I have no idea if this is a driver issue or not. I'd really hate to RMA my card. I'll open a ticket with SAPPHIRE and see if they have any advice.
I'll have to keep an eye on this - so far I haven't noticed any issues (running 2 Sapphire Radeon RX 64's). I am currently running a custom profile and the PCI-e power settings are set to moderate. This system has gone in and out of sleep mode the last 48 hours without any issues.
For now these are running on a basic test system: Intel i7 6700K, 32GB DDR4 @ 3200MHz, 1000W P2 (EVGA), 2 x Dell UP3216Q displays. Once I've deemed the drivers stable enough I'll move it over to Oscar Mike
I'm quite certain the link state is not the cause. It's probably my card if no one else is having this issue. I opened a ticket with SAPPHIRE today so I'll see what they say.
Has this happened after playing any youtube video or using Windows Media Player or Movies & TV? It only seems to happen to me sometime after using any of those applications. Granted I always have seem to encounter the bug with the playback but for some reason my computer is able to recover if it's a video in the web browser. Disabling Hardware Acceleration is a workaround for that but it doesn't fix it for stand alone players like WMP, Movies & TV, and MPC. Only a reboot will fix that.
The black screen unresponsive behavior has only been encountered twice in the 7 days that I've had the card. Both times it occurred while using the computer after a resume from sleep, though not immediately from the resume. I too am using a Sapphire RX Vega 64.
Another thing you can try as a test is to use PCI-e power cables that are separate and not the daisy chained ones. Meaning two separate 8-pin cables that connect separately to the PSU.
