Yes i'm on W8.1
My 6950 got 2Gb ram
I'm mining V8 cryptonight the lastest fork ...

So, it's hash a little now, my config parameters sucks.

I'm testing on 33B6 and with this "jce_cn_gpu_miner64.exe   Experimental boost ~2% for HD6000/7000"

I've try a lot of parameters, but get not more than  100/113 h/s  

It's crash when i up "multi_hash" value more than 240


That's the best result i can get with this config


"gpu_threads_conf" :
[
     { "mode" : "GPU", "worksize" : 8, "alpha" : 64, "beta" : 8, "index" : 0, "multi_hash":240},
    
    
],

if i try Worksize 16/32 i can't UP than 240 thread.

Did u have some values i can try ? because i've  try a lot of combination but can't reach more hashrate, driver crash.

i didn't understand whats that 2 values (alpha" : 64, "beta" :  8 ) ?

The most curious it was, if i didn't OC my card like @910/1250 driver crash instantanetly when i start miner.
in 800/1250 or 830/1250 driver crash. With all same values in config.txt . Wtf hell !!!  

I've try on each card on different PC (don't have a rig) 3 different PC.
Thx for helping.
