Yeah, every ati card I have ever owned has given me issues. Every nvidia card I have ever owned has never given me a single problem and they are all still working fine and being used today as I've given or sold all of my old cards to friends and family whenever I upgrade.
I don't think I'm going to buy an ati ever again, and I'm about to the point where I see if I can ship this thing back to newegg and get an nvidia. I just wish nvidia would hurry up and release a dx11 card.
I had this same issue when I first had my 5870 installed, after using ATI Overdrive and changing to anything other than stock clock speeds, the problem stopped. I ended up OCing my core and memory by 50.
It's worked for others too. It the problem relates to how it manages it's relaxed memory settings.
Open up Catalyst Control Center by right clicking on your desktop and left clicking Catalyst Control Center.
At the top left of the CCC, there is drop down menu labled Graphics. Click on that and choose ATI Overdrive.
Now you have to unlock the ATI Overdrive by clicking on the icon of a lock.
Enable it, and move the slider to the left or right 5 MHz and apply it.
That's it. I personally raised the GPU clock and Memory Clock up by 50, which did give me another 5 FPS in crysis.
This didn't work for me. I still ge the same problem after doing this.
I also took the card and tried on another PC
Nforce 680i sli
E6600 Core 2
4gb OCZ ram
corsair 750 tx
Windows 7 64 bit
First of all I couldn't get the sound to work through the sound card no matter what I tried. I didn't try onboard as I was tired of messing with it and just wanted to test the 5770. I booted up Team Fortress 2 and as usual about 5 min into the game I got the problem. Except this time instead of vertical tan lines the entire screen just went black.
I don't know if I should get a replacement 5770 or just get an nvidia.
Does newegg have a limit on home many times you can send back the card?
For instance could I send back this 5770, get a replacement 5770, then when that one most likely doesn't work aswell, I can send that one back and grab an nvidia?
I really would like this card to work, I NEED a card now, so I can't wait for the next batch of dx11 cards, or for nvidia to get around to releasing one. And if I get an dx10 card now it's going to be like 4 years before it's economically logical to upgrade again, so I'll pretty much spend the whole dx11 gen with a dx10 card.
