2 x HD7970 CF problems solved ! Thanks everyone.

Right yesterday I finally build my new system. I installed all the components, everything is working fine, well almost.

Any game that is being played, after about few minutes, it starts looking ugly. I get these blue lines, circles all over the place and I have no idea where it comes from.

It's all over the screen. It happens in battlefield 3, it happens in Aion.
Does not happen in Furmark when I stress the cards, and does not happen on Windows.

Newest drivers from official AMD site. During gameplay cards are about 65*C and they are NOT OC'ed.

Here are couple of screens (bear in mind that pictures will not give the same effect like it is in real. The effect is way more visible and very annoying.)

Installed the latest CAPs as well?

I notice you're not using the top PCI-E slot, what board is that? Could be not enough PCI-E bandwidth?

And that NERV sticker ;) Looking nice!
 
Corsair 800d is a horrendously poor case for air cooling. I had 2 systems built in one, and one overheated, the other, the 6970 XF setup set on fire. I even had spare fans all over the place supporting the air flow.

I moved the system to the HAF-X case and temps fell like a rock.

Not to mention that your XF 7970 cards look ridiculously close together, just like my 6970s were - check the pic here:

CAPs? And that is...? lol xD
Motherboard is Asus Maximus IV Extreme-Z
I am using top PCI-E now. It's still the same.

I'll be doing some NERV modding later...

AMD Radeon HD 7970 users - still with the 8.921.2 RC11 driver; the 7970 is not supported in 12.1 or 12.2 Preview
+
The 8.921.2 RC11 driver is intended for AMD Radeon 7900 users, everyone else should keep using the 12.1 Preview driver'

Is the proper driver for the 7970's

Smart build by the way:D

Thank you very much, I'll try them.


I will let you guys know.

It's not the best but it should be adequate given the cards are at stock. Presumably the op intends to WC fully at some point.

Check the basics:

Everything connected correctly, correct drivers cards work on their own, cards work in each and every slot etc.
 
Very nice looking machine, well built. A guy I know had the same issues when he got a new monitor, he thought he would have to take it back but after a short while (like 2 days or so perhaps) the issue just fixed itself, it only happened in games or when watching avi files was so wierd
 
With these drivers still the same.

Anyway, I've disabled CorssFire option, and now it seems like everything is fine.
But who knows, I will give it a bit more time just to be sure, then I'll be checking GPUs on their own.

Could be the board issue as well. One of the heatsinks (with red lighting ROG logo on them) below the cpu is VERY HOT. Once it reached 70*C! I don't think it's normal like.
 
Be interested to know how you get on, I'm kinda half possibly maybe considering crossfire 7950/7970's in a Corsair 800D.

Nice rig by the way, you've done a much better job of putting it together than I managed with mine!

Thank you :) I will continue working on it.

i wouldn't sandwich cards like that leave at least 1 slot between them if you can

Ye I've done it but it does not solve the problem still.

Does it do it with 1 card enabled? Try a different DVI or HDMI cable.

Nope. When the CF is disabled it does not do it.

What temperature is classed as overheating for a case? I don't see how a case like that can overheat considering the mesh vents at the back and what's left on top.

It's not really that hot though. One of my 5870's hits 75c from time to time in BF3 with a big space in between and thats due to gaming in the early hours of the morning with the room door closed. So the air isn't that refreshing.

I'm not talking about temps on GPU, but on the motherboard. That's the reason it's so strange.

The GPU that sits below... it seems fine. Furmark shows no artifacts and works fine. Same with games, no problems, everything is ok. Tested on two PCI slots (upper & lower).

The only thing was system crash and a blue screen with a code of 0x00000116.
 
make sure the cards are fully in the pci-e sockets ,i moved my pc and got the same sort of graphic distortion,turned out my cards wernt fully in
 
Have you tried swapping around the cables? Or just other cables?

Can the xfire bridge have anything to do with it? I'm unfortunately a bit unschooled in what that little thing actually does...
