Sapphire Radeon 3870 X2 card, and think I have killed it? - 2008/06/13 00:14 If I've got horizontal lines scrolling down the screen on 3D applications and the only one that can stop it is Crysis, by setting the resolution down then up again, have I fried my graphics card? I've tried BIOS, Catalyst and Windows settings, it's not overheating, I've removed any overclocking from the computer and previously it had no problem. Any clues?

Re:Sapphire Radeon 3870 X2 card, and think I have killed it? - 2008/06/13 00:24 Euh, sorry to say but what have you killed? Cause really you are whopping in but forget to mention the most important part, what kind of graphics card do you have? And what did you do, change or install before you get those lines scrolling down? And as I understand this is only in 3D applications? Meaning 2D or normal Windows usage this is not happening and what resolution do you use?

Re:Sapphire Radeon 3870 X2 card, and think I have killed it? - 2008/06/13 01:12 Lol... Sorry. I'm trying to find a solution whilst also grovelling to techies such as your good self. I've got a Sapphire Radeon 3870 X2 and I did do some overclocking on it but I've removed all of that. Everything is at stock speed and I'd be amazed if the graphics card has ever touched 50°C as I water cooled it straight out of the box so I've kinda ruled out the overclocking having done anything. As for 2D versus 3D, the desktop and anything 2D seems fine. It's only 3D stuff other than Crysis which it doesn't work on.

I doubt it's software as I've got stuff to check that and I'm fairly proficient but I'm damned if I can figure out what's gone wrong. Oh and thanks for the fast response, even if it's just to quickly strike the rear of my head. The help is much appreciated.

Re:Sapphire Radeon 3870 X2 card, and think I have killed it? - 2008/06/13 05:50 If the graphics card is damaged then changing resolutions won't fix the artifacting so I doubt the card is bad. What drivers are you actually running?

Re:Sapphire Radeon 3870 X2 card, and think I have killed it? - 2008/06/13 10:48 Well there's a thing, I'm on Catalyst 8.3 at the moment because Futuremark seems to think they're the ones to go for and who am I to argue right? But I've had the same problem in Catalyst 8.4 and 8.5 giving me a nice border around Windows but which doesn't appear in games. I swear I'm about to go bald on this little problem. I've finally got the system up to like 18k marks and now it flickers for no apparent reason. I've tried swapping from HDMI to D-Sub too to see if it was cable related and there's still the problem.

Oh and if I set the monitor to a different refresh rate, the flicker rate changes but there again it changes with the frame rates as well. When it's 75Hz it's a fairly stable flicker, almost gone with a few horizontal lines. I think it's worst when it's listing the thousands of frames per second like the pre-rendered bits on the start of games like EA's emblem etc. Then it's extremely noticable. I'd try and persuade the misses that this means I need a Radeon HD 4870 but I don't think she'd buy this reasoning. Especially as I've only had the card a few months.

Re:Sapphire Radeon 3870 X2 card, and think I have killed it? - 2008/06/13 13:27 Okay thanks for the information. Now what about using the latest Catalyst drivers? As you might know the Catalyst 8.6 are available. But make sure to clean all the previous drivers from yoru system using Driver Sweeper and removing via safe mode? Cause the behavior is strange and I also doubt it has anything to do with the graphics card really... But well not entirely sure.

Re:Sapphire Radeon 3870 X2 card, and think I have killed it? - 2008/06/13 13:35 Catalyst 8.6 is out? Oh I'm so googling that. Thanks Mavke. I'll try it this evening and see what happens. I'm thinking it maybe a BIOS problem and perhaps reflashing will solve it... Does that sound logical or just plain desperate?

If you have not touched the BIOS of your graphics card and by that we really mean flashed it than it is a though that is just not logic. The BIOS can't go wrong by just using the graphics card it can only go wrong you start flashing and something goes bad. And from what you gave as feedback you haven't done any of that...

Re:Sapphire Radeon 3870 X2 card, and think I have killed it? - 2008/06/13 19:39 Apologies again I meant the motherboard BIOS. I forgot what you guys did around here. The news is, you're a genius. I loaded the Catalyst 8.6 and all was fine, no jitters. I re-flashed my motherboard to the latest beta BIOS to see if I could get all four slots to 1200MHz which failed by the way and the flickers returned but only during the return to proxycon.

After that they stopped and having completed a nice stable 18000 marks, which at these temps I'm not going to try and beat, nice and cold. I restarted the test to see if the first test still jittered. Guess what? It doesn't. So the be all and end all is I've no idea what went wrong there but thanks to you guys it's fixed. Now I must kill people to celebrate. Cheers guys.

Re:Sapphire Radeon 3870 X2 card, and think I have killed it? - 2008/06/13 21:27 You are welcome, and well the Catalyst 8.6 did have better support for the X2 version so it didn't really came as a surprise. But I am glad it worked and do go and celebrate as much as you can and start killing some for us. And if you get the change also visit our advertisers and buy via those channels to support our website.
