I'm giving it a try. I've only mined for ~15 minutes so far with a CPU and one GPU but the fixed diff works fine to me.
Perhaps the diff you typed was ignored because the value is too low.
My actual successful test is with 60000 with this command line:
jce_cn_gpu_miner64.exe -c configCN_6C.txt -o ctl.pool.mine2gether.com:4444 -u cxorzSavc8QRe6ryCXZ7dZPzjEQG7VFRkEuTdzYc9HLFZ11J8G7MzRMgjDvKppu13s2vPcECs2fRu5o
RJ8GVjPrG12xBUyVY7.60000 -p PC40 --variation 3
And here is the result's log:
