cgminer settings for 2x7950 sapphire

[changey]

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. <clEnqueueNDRangeKernal>
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

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

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)
