Title: [SOLVED] Dual 7950 only gets 260MH per card Post by: frozen on April 17, 2013, 04:17:59 PM System: xubuntu 12.10
fglrx 9.0.2 [Sep 20 2012] Power Supply: 850W corsair I am running two gigabyte 7950's using cgminer: ./cgminer -w 256 -I 7 -v 1 -k diablo Both cards get about 260MH/s. If I only run one card, it will get about 540MH/s. What do I need to do to get both cards running at 540MH/s? Thanks Title: Re: Dual 7950 only gets 260MH per card Post by: frozen on April 17, 2013, 04:38:01 PM Some more information:
When I configure cgminer to run both cards, it doesn't actually use the second one: $ DISPLAY=:0 sudo aticonfig --adapter=all --odgc Code: Adapter 0 - AMD Radeon HD 7900 Series The same occurs if I configure cgminer to directly use the second card (using -d 1).

Apparently there's a conflict with xubuntu 12.10 and AMD catalyst 12.10 or greater. I had to install xubuntu 12.04 and install catalyst 12.8.

This is extremely helpful... couldn't find a solution for this with xubuntu, so I gave up. Thanks for posting back your results Frozen.

Hate to ask such a dumb question, but where does one acquire 12.04 and 12.8?

If you're feeling generous and have any unwanted bitcents, feel free to toss some my way. If not, that's fine too :) Title: Re: [SOLVED] Dual 7950 only gets 260MH per card Post by: frozen on April 18, 2013, 08:10:42 PM I solved this problem.

Not a dumb question. xubuntu 12.04 is available here: http://xubuntu.org/getxubuntu/ Direct link to catalyst 12.8: http://www2.ati.com/drivers/linux/amd-driver-installer-12-8-x86.x86_64.zip Title: Re: [SOLVED] Dual 7950 only gets 260MH per card Post by: tonightwefeast on April 29, 2013, 04:04:53 PM I solved this problem.
