Sapphire R9 280X 3GB GDDR5 OC DUAL-X vertical lines

Hello,

Recently I've purchased a new GPU: Sapphire R9 280X 3GB GDDR5 OC DUAL-X
I've upgraded it from a HD6950 flashed to a 6970.

It worked for a few days but recently my pc is crashing random.
All I get after the crash are some vertical lines simular to this picture: http://oi50.tinypic.com/2hqs0ub.jpg

My current setup:

MSI Z87-G45 Gaming
Intel i5-4670K
8GB of Coirsair memory
Coirsair GS600W
Samsung 830 128GB
Sapphire R9 280X 3GB GDDR5 OC DUAL-X

I thought it was the power supply just could not deliver enough power, but know I've read some on the internet I don't think this is a problem.

I've tried to set the memory clock lower to 1350Mhz but it didn't solved the problem.
Did I just received a bad GPU or are there other solutions to fix this problem?

Thanks in advance,

Mark

Memory has nothing to do with your system shutting down.
My first thought was the PSU, I know that AMD cards consume a lot but not in this case.

I think it's a bad graphics card you bought, could be broken!

Actually its not shutting down.
I'm a lot on teamspeak and I can talk to my friends when I have this problem.
I just can't do anything.

Have you checked your GPU temperatures while gaming? If they get too high it's a broken model of your GPU

Its max 60 degrees Celsius while gaming bf4 on high settings.
No matter what quality I pick, the game will crash eventually.
Sometimes I can play for 60 minutes and sometimes it will just play for 5

Sounds like infant mortality (bad manufacture)
I would just RMA it
