XFX 6950 CFX Artifacts?

post #1 of 18
Thread Starter 

Setup is in my sig. Running Catalyst 11.6 no CAPs.

I've got two of these cards in crossfire with the extra shaders unlocked. Not a 6970 bios. I ran them at 1.175v / 900 core clock / 1400 memory clock for a couple months without any problems. They are now running at 1.1v / 800 core clock / 1250 memory clock.

I recently started getting weird red and green artifacting. I'm just wondering if I damaged one, or both of these cards. The artifacts happen even when not in games. When watching youtube videos when there's movement going on I get red and green lines flashing, usually around the borders of things. Same goes for in-game. When there isn't much going on or I'm standing still the picture is perfect. It's only when there's things in motion.

I tried switching the bios switch to go to the default settings and I get the same issues. About a week ago it had gotten really bad to where when I would open the start menu and scroll my mouse up and down really fast all the buttons were getting red and green lines around the borders. Thankfully that has stopped.

I can stress test with furmark and the cards run fine with no artifacts and the temps never go above 80c. One card idles around 45c and the other around 50c.

I've created a Youtube video with my phone to show it happening when switching between pictures.


Am I F'd in the A?

Have you tried running with just one card at a time? No Crossfire with only one physical card installed?

Yeah I would run the two cards alone to see if you have the problem with one or both of them. Monitor their temperatures when running alone too.

Looks more like a parlor trick than real artifacting, especially given the correction algorithms. If you had real flaws, you'd see it everywhere.

I have tried both cards seperately in each slot by themselves and both do it. About it being a parlor trick its way worse in games and definitely not normal. I was having a problem capturing it on video in game though. Anyone think it could be the motherboard? I need to rma it for a B3 board anyway. Hopefully it is. Spent a lot of money on the cards.

Take a pic of it with your camera? Also, the way artifacts show up on radeons is usually by one of two ways. You either get them everywhere which is due to a defective card or it shows up under load which is due to the core/mem being not stable at that clock. Which way manifests for you?

Kind of neither. I get them at stock settings on my desktop and under load but not in furmark. If I'm browsing a webpage and there's pictures I can scroll up and down on the mouse wheel and I get red and green artifacts while its in motion. As soon as I stop they go away. Same in games. If I'm stationary its fine. When things are moving I get them usually around the borders of things. For example I was playing left for dead and had the flashlight on looking at a wall. If I would move my mouse quickly around I'd get red and green lines around the border of the flashlight beam on the wall. I also get it watching videos and YouTube. This is all at 1.1v, 800 core clock, 1250 memory clock.

I'm perplexed. Let me look around... on the surface it sounds like compression artifacts but its different.

I just read a thread about fried memory. Guy was asking if 1450 was safe. I was running 1400 for awhile. Hopefully I didn't fry the memory chips.

It's the voltage that degrades stuff or fries it outright, not the frequency. 1.175v is stock for 6970s so I doubt your shader unlock only did it. It's not directly applicable and personally you may just have a defective card.
