    Thread: Best Performance Video Cards?
Post: RE: Best Performance Video Cards?

i'd go with the Nvidia Riva 128, or maybe a S3 Savage 4. Voodoo 3 2000 shows great hashcat performance, too.

he should probably realize that his 4U HP server likely cannot handle any GPUs at all, and if it can, it was likely designed for Teslas. and since he's asking this question, i'm assuming he has zero e...

VCL 1.22 has some bugs, hence the note on the VCL webpage. the number of gpus has nothing to do with getting away with gigabit. ethernet latency is ethernet latency, regardless of how many gpus and...

1.21 is more broken than 1.22 ;) bandwidth is not an issue, see my passwords12 talk. latency is the issue with ethernet. you're never going to get full performance with ethernet, it is not possible...

the explanation is that you need to set an environment variable or two to use all available video memory.

give it up, your card is too old. amd does not support opencl on that gpu.

it won't affect performance, no. it will only help you e.g. load larger hash lists

yeah, we're ebaying all of our 290X's and sticking with 7970s for the foreseeable future. not enough time or patience to play games with AMD.

it would be much, much slower than just cracking locally, regardless of how many gpus you had. it's opencl middleware, so everything is sent to the compute nodes in real time. therefore you need a ...

this is a salted algorithm and you have 10 salts, so your effective speed will be 10x slower than if you were cracking a single hash. 2533 H/s * 10 = 25330 H/s which is damn close to your benchmark va...
