[LTC] cgminer configuration

[pginvest]

Hello,
I've tried to set up reaper on my laptop. (Asus M50VM, Duo P8600 @ 2.4 GHz, 4 GB Ram and nvidia GeForce 9600M GS 1GB - Windows Vista 32 bits).
With my old graphic drivers i got the error on the image below:

After updating graphic drivers to: 296.10 version i got the error:
http://imageshack.us/photo/my-images/28/reaper1ct.jpg/
http://imageshack.us/photo/my-images/33/reaper2c.jpg/ (yes again)
and sometimes the blue screen.

reaper.conf:
kernel reaper.cl
save_binaries yes
enable_graceful_shutdown no
long_polling yes


mine litecoin


litecoin.conf:
host litecoinpool.org
port 9332
user pginvest.reaper
pass reaper


protocol litecoin

worksize 256
aggression 18
threads_per_gpu 1
sharethreads 18
lookup_gap 2
gpu_thread_concurrency 6144


What am i doing wrong? Can anyone help me?
Thanks

You should use cgminer. Reaper support for NVIDIA card is a joke.
It's also dead, never updated again since April 2012.

i don't know how to configure cgminer...
As far as i know i have to compile it... i don't know how to do that (i'm not and computers expert...) any help would be appreciated

[pginvest]

Is there any tutorial to install and configure cgminer for noobs like me?

There's compiled binary in the first post here :

You must use console to type type the command parameter.

can't set it up...
downloaded from http://www.mediafire.com/?prbt07a4scihahm

running cgminer.exe
its ask fro url: litecoinpool.org
username: pginvest.gpu
passworg: gpu

i get and error saying bad url.
moreover i don't have any litecoin.conf file on folder...

You're using sha256 algo which is used in bitcoin, litecoin use scrypt.
Run cgminer with

cgminer --scrypt --lookup-gap 2 --thread-concurrency 6144 -g 4 -I 13

Can't really help much since I don't have 9600 M, you should seek help from the developer of cgminer himself.
His name is ckolivas, and here's his thread :

Meanwhile, you should set up cpu miner in your laptop to protect the litecoin network.
The speed must be small but every kH/s help.
Go solo if you can.

Your nvidia card will cost you more in electricity than it earns to mine.
Do not mine with a laptop, they are not designed to provide enough cooling to be running flat out for hours on end.
Your card only has 64 stream processors so the settings you are using will never work on it.
Get the latest binary.
Try just --shaders 64 and don't set thread concurrency or lookup gap.

LTC GPU mining is not remotely trivial to do at the moment, and it really is this hard for most people. They just battle on till they find what works.

ty ckolivas
is now at long pool activated line lets wait
I don't pay for electricity for some hours a day (work/school) he he

I get it to work but just 1.2kh/s

For anyone who is still having issues with this, I have created a program to create cgminer configurations for windows fairly seamlessly:
