Topic: ATI 5850 - Looking for assistance - page 2. (Read 2890 times)

Well I would set the one driving the display it dynamic, that's -I d and your 5850 to an intensity of 8 so that would be -I d,8, provided your dedicated mining GPU is the second one, an intensity of 9 may be better as previously said, but it isn't for my 5830.

./cgminer -o mining.location.com:8332 -u username -p password -I 9 --auto-gpu --auto-fan -worksize 256            linux

cgminer.exe -o mining.location.com:8332 -u username -p password -I 9 --auto-gpu --auto-fan -worksize 256         windoze

mining.location.com = your pool you mine at.
-u username  =   your username at pool
-p password  =     your password for worker at pool


try that

Yeah thats what I have been doing with my single 6750 card now. Using the -d setting, That seems like a good plan to set both at -d and see what happens. Ty as well!

I would first try setting the GPU running the display to dynamic intensity and and mine with and see if you have any performance problems while doing other stuff.  CGMiner is pretty good at throttling so that you can still mine while using the desktop too.

By default CGminer will use all available cards, but you can specify by using the -d (device flag) although you'll want to read the CGminer config file for exact syntax

Alright thank you! Yeah I have a bunch of different .bat files Ive written to excute different setting depending on the environment I want to mine with at currently.

But is there a setting within CGminer that tells it not to use one card, but use another? Im not sure if it defaults to use every card possible, or not. Im trying to just use the 5850.

Mind you I dont have the card in my hands currently. I wont have it until tomorrow, but I was just trying to get some good info in advance to be ready

That's pretty much it really, you may need to install drivers for the 5850, but otherwise CGminer will detect all OpenCL compatible cards. You will probably want to write a batch file to open CGminer with the settings you want for fan control and whatnot.

My friend sold me an ATI 5850 for $60 bucks. I planned on using it to mine for a few months before ASIC hits. I am also a gamer, so it will hold value to me even after I cant mine with it anymore.

Currently I am using an ATI 6750 just to do some light gaming, and mine at night.

I was planning on adding the 5850 as a second card in my system, and mine with it 24/7 until my Jalapeno arrives. I may also order a SC Single too. Still unsure of that though. But thats going off topic.

My question is how do I go about setting this up? Ive never ran a computer with 2 video cards before. I am however very tech savy, just never dabbled with multiple GPUs. I would like to keep my existing 6750 as my desktop/gaming card while using the 5850 to mine while I game, and go about my business for day to day use. Is it just as simple as putting in the 5850 into the next PCI-E slot over, and powering the machine on? Also, how will CGminer know what card to use? Im still pretty newbish when it comes to CGminer, but I have toyed around with the settings quite bit trying different command lines to get the best performance out of my 6750 in my attempts to learn about mining.

Any information would be helpful. If I failed to be detailed about something let me know, and Ill be glad to fill in any information I left out that would allow for better assistance.

Thank you!
