Thread: Quad 1080 ti Build | Need Hardware Advice
Post: RE: Quad 1080 ti Build | Need Hardware Advice
| x16 throughput is not important for most hashcat attacks. x4 is the minimum from my testing, for both hashcat and john.

Thread: [sha256] Hash inside a hash
Post: RE: [sha256] Hash inside a hash
| If it's the case that it's sha256(sha256(pass)), trying to discover that original 'pass' string is much more efficient.

Is it possible that something else is keeping your GPU busy? |
