Help for LTC mining

[fallenangel]

Hello, I'm new in the crypto-currencies world and I would like to mine LTC,
I already have a wallet, an account in a pool and "CGminer" but I don't know how to configurate it or how to begin to mine.

config : AMD Radeon HD 6800 series, windows 7 32bit.
pool : coinotron

I hope you could help me, if the answer could be written in french it'll be awesome, i'm not very good in english :/

Before I post a wall of text, what version of ati catalyst are you running? Also when configuring scrypt mining you generally want to configure it to use the least amount of power.

If I searched in the right place this is the 13.1 version, but i'm not sure if it's what you asked for ^^'

Okay open your cgminer.conf (download cgminer 3.1.0 windows built) if you don't have one start with the example.conf and save it as cgminer.conf. Set intensity to 13, lookup-gap 2, work size 256, shaders for 6850 960 or
for a 6870 1120, kernel scrypt, and make sure you have a valid pool leave everything else alone. Now create a new text file in the same directory call it mine.bat -> save as (select All files instead of .txt). The first 2 lines should have  setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1 followed by cgminer.exe --api-listen --auto-fan on the next line. Save it and then double click the bat file, after it runs stable for 5-10 minutes you're ready to start the more complicated part.

Hey, try this guide: http://cryptocur.com/litecoin/litecoin-ltc-gpu-mining/

I found it pretty useful when I first got started.

Hope it helps!

Good luck!

Step 2 is to overclock the memory(25mhz steps every 30 seconds) until the display driver crashes, now set the mem clock to the one before the crash and change the intensity to 18. Also set the thread concurrency to the number from the generated .bin file in the cgminer dir (the one after g2tc) you can also set the shader to 0 now. Restart it and now find the highest engine clock and there should be sweet spot where the hash rate drops drastically. You should now be able to get around the same hash rate that your card should get based on the mining hardware comparison on the litecoin wiki. If you aren't able to then you need to use the 12.8 driver and the opencl that comes with it.

actually I'm already lost in the cgminer.conf x) I opened it with the text editor and I really don't understand what to do ^^' (sorry for being a noob)

[acslackr5]

skip the config file and just run a command line. Find cgminer.exe and right click and make a shortcut on your desk top. Right click on the new shortcut and go to properties. From there you will see an area called Target. Add this at the end of your cgminer.exe

You will need to change the thread concurrency to the one that's for your GPU. Also the username.

 cgminer.exe -o stratum+tcp://coinotron.com:3334 -u y2bne1.5870L -p 12345 --scrypt --auto-fan --gpu-fan 25-100 --temp-target 59  --thread-concurrency 8192 -I 18 -w 256

This is a great post that helped me alot!

Make sure you read the scrypt readme file for cgminer for settings details

Also, here is a french article about mining Bitcoin and Litecoin

Bonne chance!

Yeh, tacotime posts are very helpful getting set up.  Also the CGminer documentation is good, its readable and tells you main points.  see the Readme files in the installation directories.

Tacotime's thread is excellent. Every card is going to have it's own idiosyncrasies, but you should be fine if you follow the guidelines in his thread: https://bitcointalk.org/index.php?topic=117221.0
