Title: Two different ATI Cards in one PC with cgimer possible Post by: bobafett on May 16, 2013, 05:40:49 AM Hi,
i got a ATI 7950 and a ATI 7850. Is it possible to use them in one pc with cgminer or an other mining tool? thanks boba Title: Re: Two different ATI Cards in one PC with cgimer possible Post by: reich on May 16, 2013, 06:12:10 AM I dont know sorry.
Title: Re: Two different ATI Cards in one PC with cgimer possible Post by: Chrithu on May 16, 2013, 06:39:47 AM yes it is. If cgminer is similar to poclbm you need to open an instance of the miner for each card. If you use guiminer then this is easily done by selecting file -> new miner.

Title: Re: Two different ATI Cards in one PC with cgimer possible Post by: ptereh on May 16, 2013, 04:54:02 PM most definitely possible. In cg miner there is no need to open serveral instanses, but you do need to add the right flags for each card.
I do recomend Guiminer as Chrithu mentioned. A lot easier to set up Title: Re: Two different ATI Cards in one PC with cgimer possible Post by: FlyLord on May 16, 2013, 05:07:24 PM Cgminer allows you set settings for each individual card using comma separated values. So if you want to set intensity to 17 on the first and 13 on the second card you'd pass "17,13" instead of the usual "17" for one card. You can also configure the cards once it's started by using the curses Gui. Just press 'G' to enter the GPU settings menu and take a look at what options pop up. Anything you can change on commandline should be available from this menu too

One with -d 0 and the other with -d 1 :) for CGminer Title: Re: Two different ATI Cards in one PC with cgimer possible Post by: pekv2 on May 16, 2013, 05:53:20 PM Use cgminer.conf to operate one or more+ cards, it's just simpler vs using a batch file. It's more organized.
Title: Re: Two different ATI Cards in one PC with cgimer possible Post by: InSpades on May 16, 2013, 06:03:42 PM We tested the idea when we were researching bit mining deciding on whether or not to invest into the idea. What would make a mess for graphic rendering works great for bit mining. We tested nvidia and ati cards mixed in one box. Another would have 3 different generations of AMD cards in it. To date, we have found only one card that does not work at all with cgminer (or any other opencl base miner for that matter).
Now for the sake of simplicity, predictable wattage consumption, and overclocking with utilities like MSI afterburner, I'd stick with one card type per mobo. |
