Cgminer Ubuntu with 7970 and 6950

[odee2004]

Hi,

I am new to cgminer and as well as Ubuntu.

I was able to install both and worked with my 7970. Currently with 550 Mh/s (925/775).

But when I tried to add my old 6950 to my motherboard, it does not seem to work with cgminer. It only shows GPU0 which is the 7970 card.

I am not sure if I did it right, is there a setting for the card combination?

Thanks.

Looks like you have not configured the second card as I see no mention of you having done in a terminal window sudo aticonfig -f --initial --adapter=all then rebooting so the new dual card xorg.conf file will be used.

Thanks for the response.

I was able to update it now and it is working.

Though my voltage does not seem to update using cgminer.

Can aticonfig/amdconfig udpate the voltage?

Good to hear and I do not believe that the linux driver allows you to change the voltage on the 7 series of cards at this moment.

Sorry to ask you the specifics but can you post the parameters to adjust the voltage and how to view it.

I've searched it on google and only found out how to adjust the core and memory clock.

You may get more CGMiner support if you post in the CGMiner support thread.

Memory clock is easy as you have found no clue on the voltage any time I have ever done that I have flashed the card BIOS which you cannot do on a 7 series card right now..

I see thanks.

I was able to adjust my voltage for my 7970 using cgminer but for 6950 it does not work.

I guess i'll be going back to windows for mining.

Thanks guys.
