It's the clocks changing. Disable Flash Hardware acceleration. I get that from time to time as well, the latest beta driver and latest flash in Windows8 avoids the problem, but when I close a browser window, the browser crashes.

It seems it's already disabled in Chrome.

Both my XFX 7950 (frequently) and MSI reference 7970 (rarely) do this on my 120Hz ASUS VG236H monitor. I don't use my computer with the 7950s in it at work enough to tell you if it happens with a regular monitor (the cards are used for distributed computing).
I don't understand if it's an hardware or software problem either if I'm not the only one. I'm not sure if return the card.

Hrm...try having GPU-Z open and see if clocks are changing when it happens. I'm pretty sure that's what causes the flicker, but why the clocks are changing would be an interesting thing to find out.

Flickering

Hi, all i have the same issue with my Sapphire 7950 Boost, but the flickering seem to occur when i'm playing directx 9.0c games like Fifa Online 2, Skyrim and Mass Effect 3 but when i play Battlefield 3 , Bioshock infinite or Metro 2033 then the flickering is gone. One more odd thing in Mass effect 3 when i'm exploring the galaxy i'm getting an odd lag.

Driver ver: 13.1

Install Sapphire Trixx and change your clocks (any change will do). After hitting apply the screen should go black for a moment. Does this solve the problem until reboot?

I used AMD Overdrive and set the gpu clock to stock 850 MHz it didn't help.

For what I've seen till now it seems to happen exactly when there are these clock changes, but raising the minimum clock to a max of 500/500 (instead of 300/150) didn't help.
One time it happened playing bf3, but it could have been the game (or my tired eyes :ohwell: )

It doesn't go black actually.

My Matrix card doesn't have this problem, but I see that idle is 300/600, and when video is playing, it sits at 300/1650(ram is default 1650).

My Gigabyte cards, they have lower idle clocks, and lower flash accelerated clocks, and they do this flicker at times, and when running multi-monitor, one monitor will change to a bunch of garbled mess.


So it could just be a BIOS issue, or just a clock issue. I am not sure. I'm not sure why all my gigabyte cards have flicker and such, but the Matrix does not. Also, the matrix will start artifacting at times when hot, but the Gigabyte cards do not.


I really am starting to dislike AMD cards. :p

I'll give this a try with my Gigabyte cards..I think I know what you're hinting at here.

Yes, it's really annoying. I mean it's not a cheap card, this shouldn't be happening.
Anyway I'll try increasing the minimum memory clock to 600 if it happens again now that I've gone back to 13.1 after a lot of cleaning.

I'll try W1zz's idea as well. Thing is, this flicker rarely happens. This is a driver issue no doubt about it. 12.11 beta 12's no flicker... Same with one of these 13.X beta's I've tried.

CCC Overdrive will not solve the problem, you must use TRIXX.

Another option is to go to your windows display settings, change resolution, apply, change back

it's more like a black flicker .. 0.2 seconds or so
It doesn't happen to me, I swear.
Anyway it's not so rare, it depends. Today with 13.1 I've had no flickering (but I watched only one flash video and I stayed on the web a little), a couple of days ago, with 13.3 beta 3, one or two every half an hour (quite annoying).
I'm sure that happens with 13.1 too (to me at least) because are the first drivers I installed, then it flickered and I installed the 13.3 beta 3.
Next time I'll increase the memory clock to 600 and I'll try the resolution change.

Easy way to tell if it the reference black pcb in gpuz it should say in SUBVENDOR ATI 1002

If it is non-reference it should say AIB followed by a number......

Did you try Sapphires web page and do a download bios search there?

Does it look this with black pcb and white AMD logo or the blue one you posted??? (you might want to look in the case to be sure there is 2 versions of the dual X out) Also read the bios section pics and see if one of them matches yours.

http://hexus.net/tech/reviews/graphics/37009-sapphire-radeon-hd-7970-oc-dual-x-3gb/

this is your bios not the vapor-x versions you posted ....

I have to bump this topic:

Guys I have a problem with my 7970:

Ever since I built this PC I've been having random flickers. It lasts less than a second so it's hard to capture but it's basically like white with some lines, usually not even all over screen and it happens fast. Like this at 0:29 flickering - YouTube (linked on previous page, I could never capture it myself)
It comes and goes, sometimes takes hours or not at all in days, sometimes few in a row and I thought oh well and haven't been trying to fix it until this happened:
http://www.overclock.net/content/type/61/id/1499126/

Sound and everything in background worked and I couldn't see or get out from this.
I am running latest drivers and catalyst and also have latest MSI afterburner installed, but should note it also happened on last 3 versions of drivers. I do a thorough uninstall of drivers before installing new ones so I don't think that's the problem, plus it was happening with first ones on brand new HDD and PC.

What I've done is disconnected DVI cable and tried HDMI and flicking happened. I think it's one of 3 things: graphics card is bad, graphics card interaction with monitor is bad, monitor is bad. Last one I don't think so because I play 360 and ps3 on it and no problems there. Plus I've been running on onboard graphics card and it hasn't happened yet so yeah..

I've been suggested to RMA card but I want to be 100% sure what's the problem because me RMAing it involves a lot of pain for me because I bought it in another country so yeah, trying to keep it as last option.

P.S. Thing from picture hasn't happened again.

What is your power supply, model 7970 & are you overclocking?

800W COOLER MASTER Silent, it's bit big because I'm planning on adding another 7970.

I'm not overclocking but this is a "boost edition" that's overclocked from the box, I'm gonna try underclocking it now in MSI afterburner and see if anything changes.
It's running at 1050mhz core clock and 1375 mhz memory clock.

Card's name is MSI 7970 Twin frozr 3 BE

Thanks, Looks good. You should not have ANY issues in boost or stock, was wondering if you can try uninstalling after burner & running sapphire trixx, if anything changes. Or you can OC with AMD vision engine control center also, without anything, if it clears up the problem. just sayin..

Just noticed my 7970 goes to 80c with fan on 80+% (due to fan curve in afterburner), this isn't right? This seems very excessive plus flicker problem, is it bad after all?

Was playing a game so not idle.

This card should not be running that hot " 80c with fan on 80+% ":wtf: Have you tried using the other bios on the card?? Are you the first owner of the card?
Use AMD's Driver Cleaner flip the bios switch to the other bios & reinstall the drivers. If the over heating prob still is an issue you will have to put some new TIM on the GPU lots of MSI card have WAY too much on them == over heating. Looking @ the link you posted from 'overclock' [I assume it not your card just a pic of similar issue] if that occurs on a regular basis you should really think about An RMA to MSI. You could try Posting your issue A their vid card forum & see if anyone can help

edit: So your card has NO dual bios switch???? [note pic 1__2 area]

I haven't tried using new BIOS, will it void my warranty if I do? I am the first owner and I bought it new along with rest of PC in the beginning of may so it's still under warranty and if there's anything wrong with it I'd rather send it back than spend my time fixing it and worrying about it. There's a sticker on screws so if I open to change paste it will void warranty (could remove carefully but would rather not).
It is my pic here's better link: http://imgur.com/Z7nugOz I asked there first so copy pasted it, then I found this thread on google because it was similar issue.
That thing from picture however hasn't happened again, no idea what or why it did.
Gonna post in that forum now too, thanks.
