I posted about the bug in the main thread for the second time: https://bitcointalksearch.org/topic/m.1242236

Maybe if we complain enough ckolivas will finally fix it

Problem has been fixed, now cgminer should be able to use 7xxx cards effectively as of v. 2.7.7 :-)

To answer your original question: You probably should of deleted whatever binary the program created based on your settings. Since it was originally created for a differnent generation of card that mayyy have been causing your issues.

I've run cgminer on my 7950 before with 'non-normal' --shaders set and it wasn't an issue crashing wise. (just crappy hash rate lol)

use reaper for 7xxx, cgminer struggles with large amounts of memory usage

+1 Reaper and LTC seem to pair fairly well

These are my results

reaper + LTC = Best

CGminer + BTC = Best

CGminer + PPC = Best

Reaper is working much better, thanks for the suggestions.  Smiley

Code:
export DISPLAY=:0
export GPU_USE_SYNC_OBJECTS=1
export GPU_MAX_ALLOC_PERCENT=100

Try this before starting cgminer.

I had a 5850 in my machine and was able to mine LTC without any issues.  Popped in a 7970 and update my configs and drivers, now I'm getting tons of HW errors displaying.

 U:4.7/m
 [2012-10-01 23:47:47] Scrypt error, review settings
 [2012-10-01 23:47:49] Scrypt error, review settings
 [2012-10-01 23:47:50] Scrypt error, review settings


Running the following:

--shaders 2048 --intensity 12 --worksize 256 --lookup-gap 2 -g 1

Any ideas why I'm getting these errors?

Thanks.
