Title: Stripes and flicker on screen when mining Post by: codymanix on June 21, 2011, 09:04:53 AM Hi I have bought a new graphics card (Radeon HD 5850).
But when I start mining, my computer start to get unusable. Just a few seconds after starting mining, stripes fill the whole screen, then a few seconds later the whole screen is blue, then later I see the desktop again, later there are different stripes it is always changing. The windows cursor is showing strange pixel artifacts. The Computer gets unusable and I have to reboot. The strange thing the card work well when playing GTA IV at high setting, so what can be wrong? Iam using Guiminer with Phoenix/Phatk. I have a Chieftec GPS-500AB 500W Power supply, and a MSI 770-C45 mainboard.

Title: Re: Stripes and flicker on screen when mining Post by: codymanix on June 21, 2011, 07:46:19 PM The card was overclocked by the vendor, as far as I know. My catalyst control center is up to date.
I find it strange that GTA runs very good with the card, but as soon as I start mining my desktop get destroyed :( Title: Re: Stripes and flicker on screen when mining Post by: Aristotle on June 21, 2011, 07:53:26 PM Not a good sign. That's what video cards do when they're damaged, or the voltage/clock settings are off. Check the temperature to make sure it's not overheating.

Check your temperatures!! You can use GPU-Z for that Title: Re: Stripes and flicker on screen when mining Post by: snorbit on June 21, 2011, 09:05:59 PM I had a similar issue, had to upgrade from a 450watt psu to a 600watt one to fix it.
Title: Re: Stripes and flicker on screen when mining Post by: codymanix on June 22, 2011, 09:08:30 PM Shouldn't 500 Watts be enough? Temperature was OK, if I remember correctly it wasn't more than 80 degrees celsius.
How can I check or the voltage settings? I have never done this before. Title: Re: Stripes and flicker on screen when mining Post by: freedominnumbers on June 22, 2011, 11:02:40 PM Stripes and back to desktop/application indicates a memory issue. Reduce the memory clock and see if that fixes it. If you are at manufacturer clock rates you should RMA. Bad memory happens.
Title: Re: Stripes and flicker on screen when mining Post by: codymanix on June 23, 2011, 07:03:55 AM I tried to underclock memory but it didn't help either.
Title: Re: Stripes and flicker on screen when mining Post by: alepintchap on June 23, 2011, 07:29:32 AM You shouldn't be using your computer when mining... But you could get another graphics card and mine using only one of them while you're using your computer.
Title: Re: Stripes and flicker on screen when mining Post by: Jessica on June 23, 2011, 08:01:11 AM Cool down your graphics card.
Title: Re: Stripes and flicker on screen when mining Post by: Stupidpal on June 23, 2011, 08:24:03 AM Definitely a case of overheating.
Title: Re: Stripes and flicker on screen when mining Post by: brocktice on August 08, 2011, 05:09:31 PM I have the opposite problem, I have a card that causes flickers whenever I'm *not* mining. Any ideas? Using Linux.
Title: Re: Stripes and flicker on screen when mining Post by: brocktice on August 08, 2011, 07:04:52 PM Never mind, apparently this is a known bug in fglrx 11.6, an upgrade to 11.7 fixed it.
Title: Re: Stripes and flicker on screen when mining Post by: guci22 on August 08, 2011, 10:01:24 PM Your powersupply may be insufficient. I would look into its wattage and your card's reccomended.
Title: Re: Stripes and flicker on screen when mining Post by: leeloulee on August 09, 2011, 07:32:18 PM Im getting that on my 6950 after i changes screen resulution... :-[
Title: Re: Stripes and flicker on screen when mining Post by: ian209 on August 10, 2011, 10:07:17 AM I had the same problem with Cat 11.6. Updating to 11.7 solved it.
