Unusual problem with 7970..

post #1 of 6
Thread Starter 
Here's the issues when I run it with just the Windows generic drivers:

1. I lose the signal to the screen a lot. When it does this, the computer cannot reboot/shutdown.

2. Display corruption on the windows loading screen (don't think I noticed any once into the os).

3. Windows has a hard time recognising my monitor and gpu (Wont suggest drivers for them through windows update as it normally would with other cards).


Other things to note:

1. I haven't noticed any display corruption in the motherboard bios.

2. When I try to install the proper drivers for it, I get a message (forget exactly what it says) about the install failing to some extent. But once I reboot the computer, it seems fine.


Problems with the correct drivers installed:


1. While the fan speed in percentage appears to be ok, the tachometer readings are crazy. Sometimes go up to 8 digit numbers in rpm.

Now I think that's it. I've played lots of different games on it for a lot of hours now. It performs as it should. I ran a Furmark bench, 3dmark and some unigene bench's. Didn't notice any artifacts and scores were good. However, there was one time I was playing bf3 and I noticed some artifacts. But it looked more like Directx artifacts. This was only the once too. Might have been a driver issue (Been using the 13.4 Catalyst suite the whole time).


Now I'm just trying to figure out what the problem is so I can expand my knowledge, maybe even fix it myself. So no disrespect to anyone as I appreciate all who will try to help, but the answer I'm looking for is not "RMA it" wink.gif

It sorta looks more like a software issue, but I feel there is something up with the hardware as well. But maybe not something all that major...
I've never had an issue quite like this before. Seems quite unique to me. I hope you guys can help me figure this out!? Thanks smile.gif

About the incorrect fan rpm reading, it's nothing to worry about, mine does the same thing, goes to about 700k rpm. I put a speedometer on the fan, and it's fine, just the reading is wrong.

Do you still get signal loss without crossfire?

Is it only one screen or all of them?

Have you tried changing ports?

Are they all DVI or DisplayPort?

Some monitors have been known to lose signal from DisplayPort after 4 or so hours, the Asus VG248QE being one of them

Ok. Well I'm not sure I've had any signal loss since the amd drivers have been installed. There is only 1 DVI port so I'm not able to try another.. There is also a hdmi and 2 smaller ports that are something I'm unfamiliar with. It's not my monitor. I had a GTX 670 that I got rid of when I got this card. Was swapping between them and the issues were never there with the 670. Signal loss was happening way quicker than after 4 hours too.

I uninstalled all the amd drivers today and didn't get any display corruption or lose the signal to the screen. But it was only like this for a short while until I installed the latest beta drivers. I have noticed something though. I've had artifacts in 3 games now. All Directx games. Once in bf3, once in mafia 2 and twice in arma 3 beta. The artifacts I saw in each game were similar looking. Though the bf3 one was more extreme. It's like if you turn your view angle one way, you will see a long line, but if you turn the other way a little it'll go away. It's like a texture stretching out really far or something. One of the ones in arma 3 was like that, a really long blood trail off a dead body, just 2 straight red lines going at a 45 degree angle upwards. the one that happened in bf3 was way more crazy, it was like this big blurred wall the same colour as the ground that only appeared the once, but it's basically all i could see when i turned to one direction. i moved away from the area and it stopped.I've ran Furmark which is OpenGl and had no artifacts. I've also ran 3dmark and the latest unigine benchmark (both Directx) which also showed no artifacts, though I will run them again tonight or tomorrow for another check.

I wasn't to bothered about the fan tachometer thing and it's nice to hear what you say, but I thought it might help diagnose the problem, thought maybe it was linked. But I do have some artifacts sometimes. It's really quite rare though as I say. I'm pretty sure there is something up with this card, but I can't be to sure what. In normal circumstances I would've just rma'd it. But I don't have a warranty on this so I can't. Well, unless I wanna pay a non refundable £50 fee. It'd make me sad to have to pay that, especially when the problem is hard to reproduce and so it might not even get fixed. This is why I was hoping it was something I might be able to sort myself, or least diagnose. I was really hoping that it was just a case of the windows generic driver being terribly incompatible with this card, and also that the proper amd drivers have some issues. I would be very happy to discover it's all software issues. But I'm not feeling that's the case so far.

Thanks for your reply smile.gif

The articfact you're descriibing is a texture flare, when a certain texture polygon is stretched across the screen. It's quite common in games like BF3 and it's normally in relation to memory overclock on the card, or a bad driver.

Are your cards overclocked by chance?

Ah right. Yeh the gpu clock is factory oc'd from whatever stock is to 1000mhz. And the memory is just the standard speed for these cards I think - 1375mhz (5500mhz). So you think it might be a problem with the memory? I could try downclocking it a little if this problem starts to get bad. Thanks.

Edit: This is my card: http://uk.gigabyte.com/products/product-page.aspx?pid=4102#sp
