Warranty
Limited Warranty period (parts): 2 years
Limited Warranty period (labor): 2 years for that card. I'd get it RMA'd
Here's what it takes to do 4K today. http://www.cnet.com/news/hands-on-with-nvidias-new-titan-x-graphics-cards/ so you'll need more cards and double that PSU.
It looks like a GPU failure but maybe it just overheated?
Hello,
A couple weeks ago after playing a game of league of legends my pc started displaying some weird patterns and lines. I'm pretty sure it has something to do with my graphics card (It's a Sapphire Radeon HD7950) since I'd cleaned out the dust about 2 months ago which had fixed the issue before.
Weird color patterns on screen
At this point you could still see parts of the background (1440p version of this image: background image)
After rebooting it booted into windows but shortly after the screen went striped blue/dark blue
Striped display
The problem has only gotten worse after the last time it did this, I'm currently unable to boot the pc as it displays only a black screen. (it does actually power up and all the fans move correctly)
So here's my first question: Can anyone confirm if this is a graph. card issue?
I had bought a random Graphics card at a local store only to have me bring it back later the same day.
This all happened before my pc (with my current HD7950) completely stopped working. It only displayed a black screen just like it does right now but I figured it had to be caused by my power supply (due to it not being powerful enough).
This is the reason for my second question, which is about compatability. I'll list my components so that you guys (the experts!) can help me with determining what a suitable card is to replace the defective one.
This is my system;
Motherboard: Asrock P67 Extreme4 Gen3
Processor: Intel Core I7 2600K
Processor fan: Scythe Mugen 2 Rev. B
RAM: Corsair Vengeance DDR3,1600-8GB KIT
Power Supply: XFX Pro 550W
Graphics card: Sapphire HD7950 3GB GDDR5
Case: Corsair Carbide 500R (stock fans all connected, no extra fans)
SSD: Samsung 850 EVO 1TB (Replaced a 256GB Samsung 830 when my Seagate HDD broke)
These are all older parts apart from the SSD, I bought the system back in 2012. Also recently replaced my screen which is now a Samsung U28D590D Silver (28inch 4k display).
My goal is to replace the defective part without having to replace the entire system. I use the computer mainly for gaming. The games I'd like to run smoothly if possible;
Guild Wars 2 (medium/high settings preferably 1080/1440p is good enough)
League of Legends (not that demanding compared to Guild Wars 2)
Also would like to be able to watch 4k movies without the screen tearing. My screen requires a DisplayPort connection to achieve 60Hz. HDMI only got me 30Hz and this is really a pain to look at to be honest. I believe a lot of the newer Graphics cards have a DisplayPort slot?
Thanks in advance!
