Hi everyone, I was trying to set up a 2x7950 miner for ltc. I have tried different settings from https://github.com/litecoin-project/litecoin/wiki/Mining-hardware-comparison such as --thread-concurrency 21712 -w 256 -I 20 --lookup-gap 2 -g 1 --gpu-powertune 20, but are getting the error

error -5 enqueueing kernel onto command queue.
GPU 0 failure, diabling!
Thread 0 being disabled

Does anyone know why and how I can solve it? thanks in advance!

I'm using cgminer 3.1.0 on win7
Throw this at the beginning of your bat file (if you use a bat file):
Code:
setx GPU_MAX_ALLOC_PERCENT 100

Also may need to toy around with your crossfire bridge (if you're using it, try without. If you're not using it, try with. I actually get better results and more stable system with it on)

That error occurs when you try to use a thread-concurrency higher than what you system ram can handle just keep lowering the value down until it starts working
