Sapphire 7950 acting really funny, need some advice

post #1 of 13
Thread Starter 
Starting this morning, certain dark shades of grey are now full of green sparkles, and I get thin horizontal green lines flashing every so often. It started right after I downloaded the FarCry3 1.05 patch and playing about 15min (though I don't think it's related). I have done some mild overclocking in CCC, nothing spectacular, and I have never touched the voltage.

I downloaded GPU-Z to take a look at things. My card idles from 0.8v to 0.95v but under load it jumps to over 1.2v. I downloaded and installed Trixx and sure enough, the VDDC slider is at 1250. I went ahead and moved it down a little, but if I hit reset, it goes right back to 1250.

The voltage seems really high to me, especially for a stock voltage - what do you guys think? I have already tried reinstalling drivers, what other fixes do you suggest?

Uhhh I think the voltage is normal. Can you please test again but get us some temperatures?

+ how old is it, this seems like general artifacting to me either caused by a faulty card (Vram?) or high temps.

yea, def sounds like artifacting. I would check your temps and maybe even reinstall your video drivers. maybe they got messed up during that FC3 patch....idk just a suggestion

I have restarted a few times, and I cleaned and reinstalled the drivers but am still having the same issues. Oddly enough, the card is exactly 3 months old to the day. Temps under load have reached 70C or 71C once or twice but normally max out around 65C-68C. The card is idling at 28C now and still creating the same issues.

In case it helps, I am running the 13.2 Beta7 drivers, both before and after issues started to develop.

Well temps don't seem to be an issue. Have you experienced anything wrong in other games, preferably quiet heavy games like Far Cry 3?

Edit: Infact I'm jealous on those temps @_@

There isn't much of an issue in the more intensive games, Farcry3, Hitman Absolution, etc. I think there is just so much variation to the textures that it makes the green sparkles harder to see - but if I look closely they are still there. The green sparkles only happen within areas of darker greys and blacks, so shadows and things get all glittery. However, Insanely Twisted Shadow Planet has a lot of solid dark colors and it looks like a crazy disco party - so does the default steam skin. It doesn't appear to have anything to do with the load placed on the card or 2D vs 3D.

Any other suggestions? I really don't want to have to RMA if I don't have to.

I'm just basing this on personal experience and someone with far more knowledge than me; will hopefully correct me. But it does sound like a faulty card,

My first 7970 was fine, installed, worked good for one day. Woke up next morning and my screen was purple striped and purple boxes everywhere, multiple restarts and driver re installations later the issue still continued. They sometimes just die.... in odd ways.

I really do suppose the best action for you now would be to find another video card, maybe your old one before the 7950? and see if it does it. But come to think of it, this might be a issue with the connections and / or monitor. Try a different cable and a different port in the back of your Graphic Card to your monitor and see if that changes anything, be it DisplayPort / HDMI / DVI.

Sapphire has dropped the ball with the HD7xxx series. It took them 3 revisions to fix the black screen issue on the HD7870. If you go on their forums, you will see a ton of people complaining about this issue and many others. The sad thing is that some people have RMA'd their cards and Sapphire has sent them back the card saying there's nothing wrong with the card.

Alright VawrteX, that was some absolutely brilliant advice! I use a DVI cable, and I had already pulled it out of the 7950 and plugged it into the on-board DVI port - no green sparklies, but when I plugged it back into the 7950, the green sparkles returned, so I know it's not the cable or monitor. However, I did not consider trying a different port on the 7950 until you suggested it. So I ran an HDMI cable from the card to the monitor, and no sparkles at all. Then I put the DVI cable back in, and still no sparkles. I did all this without restarting, so I restarted the computer and still no sparkles on the DVI cable. Repped!

I guess something got stuck somewhere, and forcing the card to switch outputs was enough to resolve the issue. All appears to be well now, but my confidence is a bit jostled (Capt is not helping) so I will keep my eyes open. I will continue this thread if other issues arise in the near future. Thanks again!
