for HD6950, a user on Github advises to use worksize=32 and multi_hash=864, one one thread.
Take a look at the HD6000 user topic here:
https://github.com/jceminer/cn_gpu_miner/issues/26

Code:

{ "mode" : "GPU", "worksize" : 32, "alpha" : 64, "beta" : 8, "index" : ...., "multi_hash":864 }

also try with worksize=16 and 8

Hi JCE, I'm testing on my 3 - 6950 card with 0.33b4 /0.33b6 i've also try 8 and 16 worksize. But i didn't understand whats is alpha and beta values ?!

2 VTX 6950 2Gb
1 Gigabyte 6950 2Gb
Also A Pitcairn GPU but didn't try yet.

2 os on W8.1 64
1 os on W10 x64

No card mine, and don't have error. I've never seen any hash start Cry

I post my config perhaps and i did it something wrong ?!

My start cmd file

ce_cn_gpu_miner64.exe --no-cpu -c config.txt -o pool.supportxmr.com:5555 -u 44kXLYVXRE############PDcW4kQx+5000 -p 6950_JCE
