Thread: Crypto Miner Conversion
Post: RE: Crypto Miner Conversion
| As you've identified, most mining rigs run with bare-minimum CPU and RAM, and this is far from ideal for hash cracking rigs. You can sometimes get away with an underpowered CPU, though wordlist manipu... |

How common is it for CPU cracking to be a better option than GPU? Does it come down to something as simple as hash type?

Hash type + attack mode. For ex... |

Thread: Crypto Miner Conversion
Post: RE: Crypto Miner Conversion
| Not a very astute observation. Obviously you have to give the GPU enough work to do. If you only feed 120 candidates to an algorithm that can pull somewhere in the KH/s range, then you're obviously st... |

Post: RE: 290x Stops Cracking and Hangs OclHashcat
| Those 290Xs will draw around 320W on NTLM brute force, so your GPUs alone are likely pulling around 960W. Doesn't leave much power available for everything else in your system. Plus that's a pretty lo... |

Thread: What to replace my R9-290 ?
Post: RE: What to replace my R9-290 ?
| I'm not sure where you saw the 390 has less cores than the 290, they both have 2560. In fact the R9 390 is literally the exact same card as the R9 290, it's just a rebrand, so that would not be an upg... |
