Title: Gui Miner issues with 3 GPU's Post by: kristoff on June 20, 2011, 01:42:14 AM Hello all, im fairly new to bitcoin mining. But i have stumbled upon an issue i think is worth posting about, because i have no idea what would cause it.
As you can see from the picture below, all 3 of my 5830's have been mining for about 20min, but for some reason gpu 2 isnt quite up to speed with 1 & 3. Is this a problem anyone else is having or is it some kind of settings issue? settings are as follows aggression = 7 phatk kernel worksize 256 http://i5.photobucket.com/albums/y189/azngifts/guiminererror.jpg Title: Re: Gui Miner issues with 3 GPU's Post by: pokermon919 on June 20, 2011, 01:48:15 AM You sure the OS see all 3 cards and the 2nd miner isn't on cpu?

I don't mine, but I competitively overclock and that issue in not uncommon with air cooled multi card layouts. Put a house fan pointed directly into the open side of case and see if the problem is resolved, if so, you know what it is.
