How to use gpu on bruteforcing SHA256(MD5('password'))

[Vido]

Hi guys,
I want to bruteforce hash on my gpu SHA256(MD5('password')) but cant find right number for it. 4700 is closest but does not match  what I wont. I tried this command

Code:

$ ./hashcat64.bin -a 3 -m 4700 -o cracked.txt -n 1 --increment-min=2 --increment-max=15 --bf-cs-buf=0123456789 hash.txt -D 1,2

but it giving me an error

Code:

./hashcat64.bin: unrecognized option '--bf-cs-buf=0123456789'

Invalid argument specified.

Can anyone put me on right direction
