Title: AMD 7970, Windows IE text / graphic artifacts with CGMiner, no OC. Post by: Tanquen on March 01, 2013, 06:16:34 AM I have two 7970 AMD GPUs and whenever I run CGMiner I get random text or graphic artifacts when browsing and when using some programs. While the 7970s do have a lot of game driver issues I've not seen this while playing any. The GPUs are not running around 99-100% while playing games though.
I've seen a few post with issues with certian drivers and or trying to OC but even if I underclock I see the artifacts. I'm running the AMD driver 13.2 Beta 5 Just wondering if this means I have bad GPUs or RAM and need to RMA. Thanks. My System: Motherboard: ASUS P9X79 DELUXE, Intel 3930k 3.2GHz - G.SKILL 64GB (8 x 8GB) DDR3 1600 Video Card: MSI HD7970 - R7970-2PMD3GD5 System Drive: Samsung 512GB 830 Series SSD Data Drive: Hitachi 4TB Power Supply: SeaSonic Platinum-1000W LG Blu-ray/HD DVD-ROM GGC-H20L 2 Dell 30" U3011 on Ergotron HD Dual-Monitor Arm Some pics. :) http://hardforum.com/showthread.php?p=1038475873#post1038475873 Title: Re: AMD 7970, Windows IE text / graphic artifacts with CGMiner, no OC.

You are wasting about 2/3 of your GPU's compute resources because your CPU doesn't have enough bandwidth to operate both cards at load. To fix this problem you need to upgrade to a Ivy Bridge CPU which has 2x16 PCIe lanes. Title: Re: AMD 7970, Windows IE text / graphic artifacts with CGMiner, no OC.

Edit: I think I just solved it actually by disabling the windows areo theme and using windows 7 basic theme Title: Re: AMD 7970, Windows IE text / graphic artifacts with CGMiner, no OC.

Post by: induktor on June 06, 2013, 04:15:51 PM There is nothing wrong with your card, most cards, when mining under windows do that (square blocky crap randomly blinking around the screen), don't worry, the card is fine.
BTW: it doesn't happens in linux, and also, for mining even 1x PCI-e is enough :D Title: Re: AMD 7970, Windows IE text / graphic artifacts with CGMiner, no OC. Post by: demosthenez on June 06, 2013, 04:43:01 PM Had artifacts with my Gigabyte 7970 Ghz - on 13.1.
Upgraded to 13.3b and the artifacts disappeared. |
