nivida quadro k2000 hash slow hash speed

Greetings All,

I'm currently running cudaHashcat-1.21 on a computer with a nivida quadro k2000 card however I'm only receiving 8435 H/s. I was anticipating a much hight hash rate. Can anyone point me in the right direction as to what I may be doing wrong?

Here's what I'm entering to start the process:

C:\cudaHashcat-1.21>cudaHashcat64.exe -m 2500 -o cracked.txt 23510_1407792963.hccap wordlist

Thanks in advance!!!
