try the latest version 3.3.2 http://ck.kolivas.org/apps/cgminer/

failing that some driver suggestions for the 4650 can be found here https://bitcointalksearch.org/topic/driver-problem-hd4650-and-hd6770-262381
the latest drivers probably dont work with it

I also tried installing older Drivers. Still the same Problem . Stuck on the first line ...

I had the same problem on my mobility radeon hd 5470 and I solved it by lowering my working set to 128 which then gave me a different error which i solved by removing thread-concurrency from the bat and letting cgminer set it. Resulting settings:

Code:

cgminer.exe -d 0-0 --scrypt -o stratum+tcp://eu.wemineltc.com:3333 -u hueheuhue -p hueheuhue-o stratum+tcp://eubackup.wemineltc.com:3333 -u hueheuhue -p hueheuhue -w 128 --lookup-gap 2 -g 1 -I 17 --temp-target 75 --temp-overheat 80 --temp-cutoff 90 --gpu-powertune 20 --no-submit-stale

try --shaders 320 might help it set the right thread concurrency

If you're on Windows, open cmd with Admin rights and type these commands :

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

Tried. Still the same Problem.

Use more Ram or lower your thread-concurrency setting.

4GB should be enough ?? Which thread concurrency would you reccommend ? I read on a site that it should be a multiple of 64.
I tried 1600 (64*25) but it didn't work. I also tried 768 . And 320 .

But there is a difference , when i start it there is just one line where it says :"Started Cgminer 3.1.0" before i had the "Start Screen" .

It uses about 500 MB of RAM . So there are 2.5GB RAM left (1GB uses Windows , 0,5 GB Cgminer)

the site is down . so i downloaded it from github . when i use the 3.2.2 version and start it with the same parameters as above i get :" cgminer.exe --scrypt:unrecognized option" . How can this be an unrecognized option ?
