Try this configuration:
cgminer.exe --scrypt -o
http://xxx -u xxx -p xxx --lookup-gap 2 --gpu-fan 100 --temp-cutoff 77 --gpu-engine 1000 --gpu-memclock 1350 --gpu-vddc 1.105 --shaders 1792 --thread-concurrency 21712 -g 1 -v 1 --worksize 256 -I 17
I use cgminer 3.4.2
I tried that but I got error : GPU 0 failure, disabling !!
I must admit that my cpu is AMD athlon X2 dual core 5200+ 2.70 GHz
and I use 2gig ram DDR 2
my board is a gigabyte GA-M56S-S3 with 200 Megahertz bus clock
I want to know that if hardware failure and "GPU 0 failure, disabling !!" are cause by my poor hardware or not ?
and and I also want to know that is it necessary to upgrade my rig or not?
thanks a lot for taking time
