Full Version: GPU slower than CPU?
You're currently viewing a stripped down version of our content. View the full version with proper formatting.
I recently 'installed' a GPU I was given by my dad, its an 'nVidia GeForce GTS 240'
I spent the day setting it up, then to realize that a dictionary attack with oclhashcat-plus was 10 minutes, while a dictionary attack with original hashcat took apporx: 5 minutes.
Why could this be, is it just plain and simple that my GPU specs aren't good enough or could there be something im missing here?

Thanks for your help, I can give you more information if needed.
Your card is damn slow ! 112 cores @ 675 Mhz
Buy a new one Wink

Please paste your command line and and the output, and your driver version.
How do i get my driver versions, aalhough I know I nstalled the latest version of forceware, just a few days ago.

Run a brute-force attack on those hashes instead, oclhc-plus might be just slow with your wordlist:

./cudaHashcat-plus32.bin -m 0 -a 3 -1 ?d?l?u example0.hash ?1?1?1?1?1?1?1

Post you results.
Either do what blandy said or add rules. oclHashcat-plus needs an amplifier on fast hashes to run efficient.
you want me to let it run for the full time, or just give you what its done so far?

I guess that tells me that with mask attack, ocl is faster, but doesnt really give me insight into how much faster.
