GPU diagnosis help

fmily · Mar 26, 2014

I have a Gigabyte r9 270 that I OC'ed to 1150 MHz stable but recently it has been crashing my whole computer and making it restart. I think that it may be my PSU but I don't know. It will make a pattern of vertical lines or make my whole screen one color (Blue, red, green, etc.) and make a buzzing sound out of my headphones, and my GPU isn't carrying the audio. that is why I think it is my PSU. if you have any ideas please help, I don't want to buy a new PSU but it is a lot better than buying a new GPU! thanks!

Have you tried removeing the overclock. Seems like you overclocked alot, although r9 270 should be easily overclocked to 1150 MHz and should be stable. What is the make and model of your power supply?

This is my PSU http://www.newegg.com/Product/Product.aspx?Item=N82E16817152028 It isn't very good and is over 2 years old now...
If I remove the overclock it runs fine (minus the obvious frame drop) and it even runs fine up to about 1100MHz, but just a little higher and it restarts my computer! I know it can run fine at 1150MHz because I have been running it at that speed for almost 3 months now.
Also, in case it matters, my v-ram speed is at 1600 MHz. Is that to high and causing it to crash?

Your power supply should be fine. you know overclocking reduce the life of graphic card. And you have overclocked it constantly for 3 months. Power supply should enough but 2 to 3 years might have been causing the card to act this way. Did any shock or electric surge ever happened to power supply? I had overclocked my geforce 210 and increasing only 3 MHz caused the graphic glitches and caused the pc to restart.
