oclHashcat + GTX580

[login]

I was using a pair of eVGA NVIDIA GTX480 cards with the 256.xx forceware version drivers paired with v.23 of oclHashcat. This of course worked fine. I am using Gentoo Linux (AMD64).

I've recently obtained a pair of eVGA NVIDIA GTX580 cards and was wondering if there was a "beta" version of oclHashcat that's been compiled against the 260.xx forceware version drivers that I could test drive to help certify against the new hardware. I doubt many people have a pair of GTX580s right now - so I'd like to help and offer them up for testing. I read there is a 5% performance drop when compiled again 260.xx - which might be acceptable if the GTX580s are marginally faster (15-20%) than the GTX480s I was using. Which would net me 10-15% performance gain even with a 5% loss due to driver bugs.

I've been running oclHashcat as a part of tmto.org's epiphany project (backend password cracking cluster) - and would like to continuing doing so. I'd hate to let these brand new GTX580s just sit around and not get used.

PM me for a contact email address.

yes, there is. but i am not sure if they work on 580. check PM.

After some tweaking and overclocking:

I think I can get a little bit more performance out of it.

Code:

Speed.GPU*: 3429.1M/s

For now though - v0.24 works with GTX580's and runs quite well. Without over clocking I still saw a 15% boost in performance.

For Linux you need to use 260.xx ForceWare drivers - the 25x.xx will not detect the GTX580 at all. I'm also assuming the same for Windows - but I am not using windows.

Man that's great, can you do -
./oclHashcat64.bin example.hash -n 160 --gpu-loops 1024 -m 0 -1 ?l?u?d ?1?1?1?1 ?1?1?1?l

I am totally swapping out my 480's for 580's. The EVGA GTX 580 hydro copper 2 runs at 1700Mhz stock so this will work great. This is about 30% faster than my stock running 480's.

Also what did you use to overclock in linux?
