Try disabling the DWM (Destop Window Manager Service) I hear that some people crash with it on (i personally do not mine LTC)
However the error Clearly states that its Allegedly your video drivers crashing/overloading/restarting/rebooting, Have you tried reducing the inensity? Try some default settings or a lower overclock (LTC uses memclock)

Is the card overclocked?

[lbr]

thread concurrency is too high.
Also on 13.4 cgminer can't create .bin for some reason on my rigs, 13.1 works, check if there are *.bin files in your cgminer folder to confirm.

[kamranfaisal]

Thank You for replying, i will try this right now and report back

There is  no bin file in cgminer folder. i use cgminer for bitcoin mining and that works fine, problem only  happen with litecoin mining and i am using scrypt version of cgminer.

I used ati utility to clean the drivers and loaded 13.1, my windows 2012 get  bluescreen upon boot so i had to revert back to 13.4. I use windows 2012 as my base workstation OS, not running any server type thing just find it more stable than windows 8.

i lowered thread concurrency to 8192 but still had same issue.

card is not overclocked.

Try disabling the DWM (Destop Window Manager Service) I hear that some people crash with it on (i personally do not mine LTC)
However the error Clearly states that its Allegedly your video drivers crashing/overloading/restarting/rebooting, Have you tried reducing the inensity? Try some default settings or a lower overclock (LTC uses memclock)

i reduced intensity to 10 but still had same issue. I am at loss about this...

Have you stress tested your card to see if it isnt just CGMiner?

What card is it? I had a heap of trouble with the Sapphire HD7970 vapor-x and it required a bios flash to perform correctly with litecoin.

Using Guiminer for  bitcoin mining it produces 575 mh/s, been using it for that for past few days  but i want to use it for litecoin guiminer scrypt.

[kamranfaisal]

Probably a dumb question but how do i reflash it?

[krusin]

hmm, I don't know anything about guiminer, I use CGminer. You can get the gist of reflashing here https://forum.litecoin.net/index.php/topic,2963.0.html I don't know what bios you would need. Before you flash things, is there a guide to setup guiminer somewhere? CGminer has the Scrypt-readme text file that comes with the program to get you started. It took me about 2 hours to dial the cards in to their max before flashing.

I tried cgminer directly as well using the following command but it produces same error (really pulling my hair lmao)

cgminer --scrypt -o http://pool.litebonk.com:3333 -u username.1 -p passsword --thread-concurrency 8192 -I 10 -g 1 -w 256

[krusin]

The best advice I can give you is to follow the scrypt-readme text file. It will take a bit, but you will get it.
My settings are
setx GPU_MAX_ALLOC_PERCENT 100
color 02
--intensity 13 --thread-concurrency 8192 --gpu-threads 2 --gpu-fan 100 --gpu-powertune 20 --gpu-engine 1045,1040,1045 --gpu-memclock 1500
I get 2.176 average with three Vapor-x 7970 cards.

I have a similar problem on with CGminer on Linux. Whilst mining BTC is fine, and I compiled cgminer with scrypt enabled, as soon as I use

./cgminer --scrypt _other_options_and_pool_info

cgminer almost immediately segfaults.

Is there another GPU miner for Linux other than cgminer and Litecoins I could try to compile that would work well with ATI Radeon 7850's and 7950's?

If you find one please let me know, i am pulling my hair over here and going bald lol

This is really bizzare... Someone call Kanoi or ckolivas, Hell even Luke-Jr could help.
This is probobly a Stupid question, But have you tried cleaning the drivers via AMD's driver cleanup utility? (I have harsh doubts that this will even make a differance since your btc mining is fine)
