i'm having the same issue as described above BUT i'm at work now and can't provide the logs (i'll post the logs in a few hours)
to clarify my rig crashes only in games and it seems to correlate to dips in gpu activity (just a pattern i noticed that might have nothing to do with it).
when stress testing i left furmark running for a few hours with no overheating and no crashes (gpu activity 100% through out the stress test) but one quick bootup of witcher 3 killed it in minutes.
the Internet has come up with a workaround that worked for me like a charm (somewhat).
power limit set to +50%
custom fan curve to avoid going to 0 RPM - mine is locked at 2000 rpm (g1 gaming card)
the above results in less frequent crashes (once every few hours) as opposed to every 5 minutes of game play in witcher 3 and every match in heroes of the storm with stock wattman settings.
this was last nights tweak:
for my setup setting gpu frequency to +10% bumped up the stability even more (no crashes last night)
even tho the workaround seems to do the trick it's a workaround and not a proper fix.
Gear:
cpu: AMD fx-8120
mobo: GA-990FXA-UD3 rev 1
gold rated 750W PSU from corsair (3 yo) (will come back with exact model number)
gpu: gigabyte g1 gaming rx 480 8gb
insane cooling and airflow throughout the case:
2x200mm fans providing airflow (1 intake + 1 exhaust) + 1x140mm exhaust fan drawing hot air from the d14
noctua D14 on the cpu
case ambiant temerature 45C while stress testing with hyperPI and furmark (the cpu has never seen 65C temperatures in it's life)
notes:
windows event logger is just useless registering a kernel-power outage event (so the restart of the system) and nothing else.
temps are way lower than my previous card (HD 6950) even with uber-stress
bios of both mobo and g-card are latest and at default settings (bios reset was done prior to installing the new card)
memtest on the ram was clean
psu is underloaded (it might be able to handle 2 more rx 480)
cpu is cool and at stock frequencies
drive versions used where 16.12.2 and 17.2.1 with clean install/uninstall under safe-mode windows and normal operations with no stability improvement
TL,DR:
-system crashes in games constantly with default wattman settings
-overclocking dramatically increases stability
-hwinfo64 logs coming in 8 hours
