Best way for LTC mining with two cards (5870 and 7850)

[malvino]

Hi to all!

I have a 7850 mining litecoins with reaper and already bought a 5870. I've tried to mine with the two cards on reaper but I couldn't. Could you give me please some tips to mine with these two cards?

Thank you!

Use either cgminer or bfgminer (or both).  If you use just one, you have to run two different instances with them, and on each disabling the card for that mining session.  At least, thats the word around the interwebs on how to do it.

Thank you Zanatos666. Do you have the settings for these cards? 

[Zanatos666]

That I do not.  I have never LTC mined so I dont know any optimal settings.  Do a quick Google search and you should find something.  The biggest thing I know is thread concurrency and tweaking it. You usually have to start low and then slowly increase.  Going to high too fast will cause crashes.

If you're on Windows try guiminer scrypt, it comes with good default settings for ATI gpus.
