can't mine with GPU

[trady]

i'm a newbie here and i have a problem when mining by cgminer

it manifasts as follows:
 [2013-12-10 20:19:08] Started cgminer 3.7.2
 [2013-12-10 20:19:08] Loaded configuration file cgminer.conf
 [2013-12-10 20:19:09] Probing for an alive pool
 [2013-12-10 20:19:10] Pool 0 difficulty changed to 16
 [2013-12-10 20:19:11] Network diff set to 4
 [2013-12-10 20:19:11] Error -55: Enqueueing kernel onto command queue. (clEnque
ueNDRangeKernel)
 [2013-12-10 20:19:11] Error -55: Enqueueing kernel onto command queue. (clEnque

 [2013-12-10 20:19:11] GPU 0 failure, disabling!
 [2013-12-10 20:19:11] GPU 0 failure, disabling!

then i have nothing to do but close cmd...
i just cannot start mining...so what's the problem?

win7 64bit
video card is ATI Mobility Radeon HD 5470
(seems not good for mining...)
as to pool, I've tried minepool and cryptcoins but they have no difference when it comes to cgminer
any detail needed?

THANKS A LOT!!

It takes a little tweaking.

read: https://github.com/Anoncoin/anoncoin/wiki/Mining-hardware-comparison#wiki-ATI_AMD_GPUs   
and the readme file of the cgminer.

I use cgminer 3.7.2 with a 7870:

cgminer.exe --scrypt -o stratum+tcp://xxxx:3333 -u xxx.h -p xxxx  -I 12 -g 2 --thread-concurrency 8000 -w 256 --gpu-engine 1100 --gpu-memclock 1400 --lookup-gap 2 --expiry 1 --queue 0 --no-submit-stale -s 1

I think the -I 12 -g 2 -w 256  options are needed for it to work.

thanks but ...it doesn't work for the parameter you gave
besides, the page doesn't lays my gpu out...so it means... is it really bad for mining or ... too new?

I didn't say my config options would work for your card.

For a start try with  cgminer.exe --scrypt -o stratum+tcp://xxxx:3333 -u xxx.h -p xxxx -I 12 -g 2 -w 256 , and add parameters to see if it works. Look for the nearest model of your card on github for options.

From github link:

5450    21.6    ?    891 MHz    875 MHz    cgminer 2.11.3    --intensity 18 --lookup-gap 2 --shaders 80 --worksize 256 // Arch linux, Catalyst 13.1-4

So try  cgminer.exe --scrypt -o stratum+tcp://xxxx:3333 -u xxx.h -p xxxx -I 18 --lookup-gap 2 --shaders 80 --worksize 256

Play a little with options (read the README file).

it works when use the software in version of 2.11.3 !! really helpful
though the 18 for intensity makes my laptop crashed...and the speed is even slower than my cpu...
thank you a lot!!
