Title: Litecoin mining tips? Post by: The Extreme on May 09, 2013, 05:23:24 AM Greetings-
I have entered into the world of mining Litecoin! As I am new at this (as with most things crypto-currency) I wanted to see what I might do to improve my results. First off, my hardware: Athlon II X4 640 8 GB PC3-14900 DDR3 RAM Sapphire HD 7870 XT 2GB Windows 8 Pro I'm running the latest Beta Catalyst drivers from AMD (12.104 drivers I think?). I'm running cgminer - GUI miner does not want to work. I am part of a pool, not a solo miner. My setting so far on cgminer are: --scrypt --thread-concurrency 16384 --lookup-gap 2 --gpu-threads 1 -I 18 -w 256 I'm getting about 400 kH/s with this setup. I should note the card is slightly underclocked - 850 MHz core and 1500 Mhz memory. Yes, that seems counter intuitive, but I saw that advice on a board recently and it's been my best result. Still, I'm getting only 400 kH/s and because my card is uses a Tahiti GPU (albeit an LE-based Tahiti), I'm thinking should be able to get closer to 500. This config runs the card up to 83 degrees C and the fans are running at 78 percent or so. My questions: -Any ideas on diff settings that might do better for me? -I'm trying to hold my card temps to 85 C or below... Is 85 too high? I know most of us would prefer to see temps below 80 or even 70 full time. -I'm trying to hold the fan spin rate to 90 percent or below. This setup is yielding about 1 LTC per day - not too bad, I suppose - and I'm getting very few stale hashes too. But I know there are those on this board who could help me get more out of my setup. I want to maximize my hashing, but neither am I interested in seeing my GPU melt down in a year. I'm curious to hear any advice anyone might have. Thanks! The Extreme Title: Re: Litecoin mining tips?

Title: Re: Litecoin mining tips? Post by: The Extreme on May 14, 2013, 03:02:40 AM Wow... surprised no one seems to be able to offer advice on this one ???
Let's try one more: bump Title: Re: Litecoin mining tips? Post by: i3lome on May 14, 2013, 03:10:40 AM I figured a pro would help you by now. I mine with CPU but i looked up some stuff for you and these are the settings and speeds I have found.

Post by: bitcoin-world.de on May 18, 2013, 02:43:30 PM I have 2x Gigabyte 7950 it was clocked by stock with Core 1000 Mhz and Ram 1250Mhz and was running at high 1.25V . The Temps were by 75° -85°.
Have downgraded Bios, then they run now at 1100Mhz Core and 1250Mhz Ram at 1.1 V and runs much cooler now (5°-8° Difference) with the same hashrate each Card 650khash/s in LTC. If someone needs help in mining write me PM. Title: Re: Litecoin mining tips?

Title: Re: Litecoin mining tips? Post by: i3lome on May 18, 2013, 10:24:20 PM who mines with a cpu? Is that even worth the power? I do, if your trying to make a quick profit, don't. I get around ~23kh/s which gets me 1 Ltc over around 2 months. I do it because I like crypto and don't have the money to buy in and get a GPU. So I mine slow then use Btc-E to multiply my LTC. Went from 0.2LTC to 4.69 Ltc in a month Title: Re: Litecoin mining tips? Post by: The Extreme on May 25, 2013, 03:24:32 AM Thanks all 8) This info will be useful.
I'll be sure to be back in touch for any questions... |
