Black Screen under heavy load: GPU possibly overheating?

[omegarugalard]

Hello everyone,

I'm having an issue with my screen going black while playing games for short periods of time. It seems like this happens once my GPU temps reach a certain degree (over 77c). I'm just wondering if anyone has personally dealt with this issue, and can help verify this suspicion as it seems to have followed me from a previous build. GPU temp is the only thing I can think it may be. I used to run 2 xfx rx 580's in crossfire on an old FX-8350 build, and kept this problem under control by keeping temps under 82c. If I left the GPU fans set to auto, temps would rise well into the high 80's to even 90+ and ultimately black screen. I wasn't sure if what seemed to be a temp issue was just because my old pc was in fact old and dusty, so I cleaned it up but nothing seemed to change.

Since these cards were fairly new (about 2-4 months old) I figured i'd try them in my new build to see if anything changed before buying a new GPU for it. Unfortunately my current setup is experiencing the same issue, but at even lower GPU temps. If they hit a degree higher than 77c the screen will go black displaying a loss of signal, and leaving everything unresponsive as far as I can tell with audio still playing (sometimes looping sound). All of the fans kick into high gear at that point, and I have to power it down. I'm just wondering if maybe i'm missing something here before I scrap these guys. My cpu temps seem to be fine (52c when oc at 4ghz under load. quite a bit less at stock), and I don't think my psu is a problem either. Everything in my new pc is about a week old, so it's brand new.

What clock speed and voltage are you running the cards at? I have an XFX RX 580 GTR-S 8GB that I am currently running at 1515 MHz core / 2250 MHz memory.

I can verify your suspicions about the temperature. Below 78°C my card runs flat-clocks in the Firestrike Stress Test. It starts dropping clocks and getting unstable somewhere between 78°C-82°C. It seemed to me, while overclocking, that the offending temperature got lower as my clock speed increased, as well. Below 1500 MHz I was stable up to about 82°C, at 1515 MHz it starts dropping clocks and artifacting at 78°C, but is rock solid below that.

I'm actually kind of glad to hear of another card behaving the same way!
