Title: Running 1 Nvidia and 1 AMD at the same time! Post by: valkir on January 20, 2014, 02:54:49 AM Hey guys
I know it's bitcoin channel and everyone will tell me do not mine BTC with GPU. I know, I got 40gh in BTC in ASIC. Ok, Now I got 2 gpu that are sleeping in my house. I will like to know how I can mine with both if they are 2 different company card. I know how to use Cudaminer and CgMiner but when I start CGminer he choose my nvidia (because she is the main board) and then it crash. How can I tell CGminer to use the second gpu?? Thank ;D Title: Re: Running 1 Nvidia and 1 AMD at the same time!

Thank ;D if you have 40gh/s for btc mining, why not just mine scrypt crapcoins and sell them on crypsy for btc? Title: Re: Running 1 Nvidia and 1 AMD at the same time! Post by: Kluge on January 20, 2014, 03:02:39 AM Your mining software is male, and your graphics card is female??? Okay...
Anyway - use "-d 1" argument in .bat file or if you use command line. If you don't specify the device you want to use, it will use both the NV and AMD card. If you use the .cfg file to start cgminer, I'll have to look it up for you. (and yeah - mine Scrypt and sell for BTC - way more profitable. Look into middlecoin.com if you don't want to deal with the altcoins. You mine altcoins, but they exchange them and pay out BTC.) Title: Re: Running 1 Nvidia and 1 AMD at the same time!

So I will try -d 1 thank ;D edit Command line set a divice that doesn't exist >:( Title: Re: Running 1 Nvidia and 1 AMD at the same time! Post by: Kluge on January 20, 2014, 04:30:47 AM :D sorry I'm french Canadian! Not perfect in english anyway. If you use -d 0, I'm guessing it crashes? Do you have the latest (and full) AMD drivers for the card?So I will try -d 1 thank ;D edit Command line set a divice that doesn't exist >:( Both the Nvidia card and AMD card should both have OpenCL, which means they should both be detected as devices. If the Nvidia card is in the first PCI-e slot, it should be device 0, while the second device (the AMD card) should be device 1. Dunno what's going on.

Yes, this site here shows you what is most profitable to mine (scrypt): http://coinwarz.com Title: Re: Running 1 Nvidia and 1 AMD at the same time! Post by: ak84 on January 20, 2014, 06:47:07 AM for cgminer, use:
--gpu-platform 1 or 0, depending on your card's PCI-E placement on your motherboard. Make sure it's mining on the AMD card. Then run cudaminer as well for the nvidia card. |
