AMD 390 DEAD ?

[FlyingPanda]

Is it possible that i damaged my msi 390 ? I was overclocking trying to hit 1200mhz since it was able to do 1180 with 100mv+. I used Trixx to add 200mv+ with 100%fan and a big fan blowing air at it, it passed the firstrike test hit 92c at max, i went to try Valley and then it starting artifacting (looked like heavy screen tear) so i quit it to back off the clocks but it kept doing it in windows so i freaked out and restarted windows, now i can even get a 1100mhz OC with 100mv+ its just not stable and i seem to be getting lower results then a standard 390 at stock. Opened the card up it seem brand new other then some of the surfaces look shinny as if it had glue or something. now im worried i killed it. i also reinstalled drivers just in case. Also as a side note i kept getting a bug where the gpu would be at 100% at idle, you guys think that might have messed up my card when i added the 200mv cuz under a real load it lowered the Vcore to 1.3 from the 1.4? maybe when i went back to normal windows the Vcore spiked with that bug and cuased damg? Help plz System Configuration: Motherboard: Asus Maximus extreme 4 CPU: Intel xeon 1240v2 Memory: 8gb DDR3 1600mhz GPU: MSI Gaming R9 390 Driver: 17.3.1 OS: Windows 10 x64

Likely voltage damage. If you put too much voltage into your GPU, just as with a CPU, it will die. Obviously this will take more or less time depending on the voltage added. However, GPUs are typically a lot more sensitive to voltage. It is extremely likely that you have overvolted your GPU. I would RMA the card, but before doing so, test it out in someone else's system if possible. Side note: AMD GPUs are not good overclockers. Always look on the internet to see what people have gotten on it before overclocking it with extreme voltage. If you do manage to get a new card via an RMA, please don't do this again.
