GPU cracking is too slow

[khawasli]

Hi,
I have an Alienware 18 which has two GeForce GTX 770M GPUs

I tried to test crack an MD5 hash and the speed I was able to achieve was 2163 Khz /s even though the speed of my card is 797 Mhz I also looked at some videos on hashcat and read about it and mostly everyone is able to achieve a lot faster numbers. In fact I noticed my regular CPU is faster than both my GPUs put together !!

Any advice?

Code:

khawasli@khawasli-pc ~/programs/oclHashcat-1.01 $ ./cudaHashcat64.bin -m 0 /home/khawasli/hashes/md5Hash /home/khawasli/hashes/all.lst
