Just upgrade my mates PC to a RX 480, the power supply is 550W and is Bronze certified so it should be more than capable of running it, I'm running the latest drivers but for some reason the display will just completely cut off after about 10 to 20 minutes of gaming, after hard resetting the system it will be displaying fine again, is anyone else have this issue as well?
Have you downloaded the latest drivers that are supposed to fix the motherboard power draw issue? http://www.tomshardware.com/reviews/amd-radeon-rx-480-polaris-power-fix,4668.html
This isn't power draw issue.
I personally haven't seen this issue. Your best fix is RMA.
All power saver settings turn off sleep/hiberate ? What drivers are you using ? Assuming that you are using windows, windows 10 doesn't like beta drivers :( Is all the drivers for your system completely updated ? What are your temps like ?
maybe it's the monitor?
Using the latest driver, tempted to try the older ones but I'm afraid it'll brick his PCI lanes, tried it on both my test monitor and his TV and it's the exact same result, might have to RMA but want to do that as a last resort since it will probably take 2 weeks to get a replacement, is there any harm trying the older drivers for a short period just to make sure it's not a driver issue?
depends what motherboard does he have if its a cheap one it may have problems but it might not as well
can't remember the model number off the top of my head but it's one of MSI's lower end 970 motherboards
just noticed the driver version is 16.7.2, didn't they fix the power issue in 16.7.1?
Try setting it to compatibility mode.
I've downgraded the drivers to 16.7.1 and he's taken it home for the night, I'll tell him to do that if the problem is still there
Also keep an eye on the temps, and make sure that there isn't anything messing with the drivers (maybe an older version that was never uninstalled or something). Could be seeing some instability on many levels. driver, gpu, vram, power, temp, etc. So watch temps for now and make sure the voltage and clock speeds seem stable. I am guessing that everything is fine and within spec, and then it just shuts off the output. In which case, if switching to a different video out on the card doesn't fix it, then you might have to rma. Could try a different psu and/or mobo and see if that helps. But if the psu/mobo is the issue, then the compatibility mode should solve it.
it will not brick anything - gamernexus tested it and it worked without issues on cheap mobos below spec.
I've had something like this happen to my R9 380 but it only happens rarely when I'm playing and trying to stream battlefield with AMD's vce (obs fork) then it shows no signal on all my mointors and I have to hard reset. Maybe try doing a small under clock and see if that helps
