Title: Litecoin giving less has rate than benchmarked Post by: Madazam on June 13, 2013, 10:23:25 AM I have 5970 on a small rig. With Bitcoin it produces around 670MH on stock and over 700MH with overclocked to 760mhertz with mem usage as 160. Which is inline with :
https://en.bitcoin.it/wiki/Mining_hardware_comparison#Graphics_cards I tried LTC and with all the different cgminer settings it doesn’t seem to give me anything above 150 KH which is not inline with as it should get around 750 KH : https://github.com/litecoin-project/litecoin/wiki/Mining-hardware-comparison I have tried different shaders and other settings but doesn’t seem to matter. I am thinking may be my RMA is low (2 gb) or may be the cgminer settings are not optimal. Advice needed : 1- Do I need more RAM? 2- Do I need different setting for cgminer? If I do, than can anyone post there sample .conf file (without the pool information ofcourse ^_^) for 5970? Thanks Title: Re: Litecoin giving less has rate than benchmarked Post by: mm8000 on June 13, 2013, 10:32:32 AM cgminer intensity settings are different for scrypt coins.
Where as bitcoin cgminer intensity 13 is max 20 is max for scrypt coins. So start increasing that I flag. cgminer I 20 --scrypt Title: Re: Litecoin giving less has rate than benchmarked Post by: TheSpiral on June 13, 2013, 12:07:36 PM cgminer --scrypt -I 20 -w 128 --thread-concurrency 8000 --lookup-gap 2 --gpu-memclock 1250 --gpu-engine 944 --shaders 1600

Or get guiminer and use the supplied pre-set or get the release of cgminer before the newest one.
