Now you can set starting difficulty value by typing like "d=0.01" at worker's password.

This would help big hash miners to catch up to its own hardware limit faster than ever.

1. Run your miner program and check your difficulty value.
    Keep in mind that difficulty value must be stabilized.
    We recommend you to get difficulty value at least after 10 minutes of mining.

2. Set this difficulty value to worker's password as "d=XXXX"
   ex) d=0.0312
   Do not write this value to miningpoolhub's worker page, just write it at miner configuration file.

3. Now run your miner program again.
   You will see your miner running at the difficulty value you typed.

4. Difficulty value can go up and down again. It's not a bug.
    d=XXX just gives us hint at start and it doesn't enforce diff value to be fixed.


Far wrong diff value may corrected automatically, but you'd better write optimized value.

Big hash miners who are using rentals, multi-algo, ASIC would get better result with difficulty hint.

Just create a new worker and leave with account default job then use the credentials here instead of XXXX

this will work for 1 GPU for 2 you need to change SelGPUDSTM '0 1' -SelGPUCC '0,1'

In the password field add this

-t 1

eg

-o stratum+tcp://xevan.mine.zpool.ca:3739 -u YOUR_BITCOIN_ADDRESS_HERE -p c=BTC,d=0.003 -t 1

See the end of the command line, this tells Awesome Miner to use the first GPU only.

All of this below is put in the password field

c=BTC,d=0.003 -t 1

c=BTC << this is a payment symbol (bitcoin), it's used with my bitcoin wallet address

d=x.x << this sets the difficulty for the GPU

Update: The -t command disables all other GPU's, I am looking for a fix.
