But i thing your hashrate be LOW LOW LOW - no more than 25 kh/s https://litecoin.info/Mining_hardware_comparison Title: Re: help with litecoin mining Post by: kr15davis on January 30, 2014, 09:48:16 PM should i just invest in a ati graphics card and i might have less problems?
Title: Re: help with litecoin mining Post by: Speedy on January 30, 2014, 09:54:46 PM cudaminer is ok, but you might not get the fastest speeds with it.
I got 160khash on GeForce 660. I get the same on Radeon 7770. ;) Title: Re: help with litecoin mining Post by: kr15davis on January 31, 2014, 03:20:53 AM im now using cudaminer with the wemineltc.com

Title: Re: help with litecoin mining Post by: Sonny on January 31, 2014, 03:16:54 PM should i just invest in a ati graphics card and i might have less problems? The hashrate is much better with ATI/AMD card. If you really want to do mining, you could try that; or you could direct buy some btc/ltc for investment. Title: Re: help with litecoin mining Post by: oxfardk on January 31, 2014, 09:10:10 PM AMD cards are so much cheaper and more interesting hardware furthermore you can altcoin mining pretty fast
