What PSU are you guys running a VII on?
I'm not sure if I have a bad PSU (750w EVGA G2) or it's driver/card related.
My current issue is that I can test heaven no issues at stock/995mV, but have crashes that I can't narrow the root cause too other than either a faulty card, bad driver, or PSU. Memtest and CHKDSK shows good on both.
Currently on a 950F 3440x1440 UW main monitor and a 1080p 144hz benq (non sync) secondary.
However, if I'm playing a game and tab or click to discord (hw acceleration off) it will cause black screen and hard lock my comp forcing a restart. I'm able to replicate it in WoW farily easily (Fullscreen Borderless option) when I click from WoW to Discord and back to WoW it will stutter, lag, and eventually the displays stop and the computer will restart.
Even at stock settings this will happen.
I had a GTX 970 previously, and used DDU clean wipe to shutdown for new card before installing R7.
I noticed somebody else in this thread had a similar issue when installing the drivers, and I also ran into this problem too, during the install of the drivers where it didn't recognize the driver type saying "radeon settings and driver versions do not match", even though I know for sure it's the Adrenaline 19 for Windows 10 64bit. When I installed the drivers, it was installing what appeared to be an 18.5 previous version, but once installed the drivers read as the adrenaline 19 version. I've tried installing it multiple times also, and get the same message each time.
I've tried using just the ultrawide, thinking it was related to the second monitor, but I can replicate the slowdown by alt-tabbing.
I've tried disabling Freesync, thinking it was sync related on both the monitor and the driver (no results).
Tuning the monitor from 144hz to 120hz showed the same results.
I've ran DOOM Full screen (with both monitors plugged in) and it crashed shortly before the tutorial stage ended. (This is what leads me to believe it might be power related and my PSU is crapping out on me).
Like I said, I'm not 100% sure on the root cause, because I've been hearing many reports of buggy drivers, and my card seems to be fine in Heaven benchmark at both stock and undervolted.
I've been busy working since Friday, so I haven't had enough time to fully tinker with it, but I'm wanting to throw this information out there incase somebody else has this issue or had this issue and resolved it.
My next step will likely be fully re-imaging my desktop.
Sorry for the long post :x.
