Thread: Founders Edition out of stock
Post: RE: Founders Edition out of stock

Thread: oclHashcat without window manager
Post: RE: oclHashcat without window manager
| just because you need to run x11 doesn't mean you need to run oclHashcat from within a window manager. you can still run it at console if you export the appropriate display. |

Thread: Learning to crack 7z archives

| 7zip is a very slow algorithm, so your attacks have to be very targeted. Also your GPU is not very good for hash cracking, so you have to be even smarter about your attacks than those with better-perf... |

Thread: Cost optimized GPU farm
Post: RE: Cost optimized GPU farm

| this is expected because you aren't giving the left side enough work to do. i'm surprised your gpu utilization is that high, when i try your mask i only get about 2% utilization on one GPU. |

Thread: Is this WPA2 Password uncrackable?
Post: RE: Is this WPA2 Password uncrackable?
| It's not an error, it's purely informational.
You can also shorten your command line up quite a bit by using -1 ?d?l?u instead of manually listing out all of the characters in the character set. |

No, your CPU is likely much slower. I reckon you'd probably only get around 8 KH/s with your CPU.
