Thread: Advice on HP Nvidia Tesla K40 GPUs
Post: RE: Advice on HP Nvidia Tesla K40 GPUs
| Yeah, you won't find much out there about the K40. Very few people crack with Teslas since they're slower than their GTX (and now RTX) counterparts at 15x the price. And Kepler is especially garbage f... |

Thread: Advice on HP Nvidia Tesla K40 GPUs
Post: RE: Advice on HP Nvidia Tesla K40 GPUs

Thread: Advice on Rack Chassis for RTX FE GPUs
Post: RE: Advice on Rack Chassis for RTX FE GPUs
| Nvidia RTX 20-series is an exception to the "always buy reference design" rule. You definitely do not want the FE cards for Hashcat. |

Thread: again AMD (290X/390x) vs NV GFX 970
Post: RE: again AMD (290X/390x) vs NV GFX 970
| GTX 970 is roughly the same speed as 290X while drawing half the power, and won't damage your motherboard like the 290X will. And also fuck AMD. |

Thread: Agilebits 1Password support and Design Flaw?
Post: RE: Agilebits 1Password support and Design Flaw?
| you're assuming brute force, which no one would be dumb enough to do.
a more significant measurement: 3 MH/s means we can get through rockyou in 4.7s, rockyou + d3ad0ne.rule in 90m. |

counterwallet.co which issues the user 12 random words as a password.

12 words completely defeats the purpose of using passphrases. |
