Gtx 860 m Problem

[br.]

Hi all i am new in hashcat
i use windows 10 and gtx 860m 
i converted cap to hccap file and i try cudahashcat and i see this

Code:

C:\cuda>cudahashcat.exe -m 2500 -a3 cansu.hccap cansu,?d?d?d?d
cudaHashcat v2.01 starting...

ATTENTION!
 The wordlist or mask you are using is too small.
 Therefore, oclHashcat is unable to utilize the full parallelization power of your GPU(s).
 The cracking speed will drop.
