Admin @ InsidePro has just released a new version of his GPU hashcracker. Major spotlights: Up to 256 different attacks can be specified to run in one run, no need to make 256 batch files for that...

Usually, it worked like that(with each new release of drivers current oclhc worked with them). However, knowing NV, they may make some serious changes(or implement serious bugs) in 260.xx . When the...

2 5970s will be very nice when crazy ati developers fix the opencl runtime bug, which doesnt allow to properly use 2 GPUs of 5970. Right now, using oclhashcat with 5970s is not worth the effort. P...

Post: RE: ATI and Nvidia - same system?

Working together = not possible. Using either gtx 480 OR 5670 is possible. You only need to specify platform(-p flag). However, I suspect that it is possible to run 2 seperate oclhc instances, one for...

Try -p 1 and -p 2. I have a feeling they dont begin with one.

Oclhashcat does not have simple wordlist attack, and will not have it in the future. It's made for combo attack, with 2 sides. So oclhashcat.exe hash_file dictionary_file will not work. I have no...

GTS 450 = sm_21 = pain in the ass to get 100% shaders working. But it's cheap :)

Post: RE: New Graphic Card, whichh should I buy?

If you dont mind the price, buy Radeon 5870 or GTX 480 . They are top for amd and nv atm. Just make sure they are properly cooled, so buy a model with non-stock cooling.

Post: LM hash support for OCLHC

I'd wish to see it.:) It may not be bitsliced. Ofc, it may not be possible to implement with current oclhc architecture(because of 7+7 password length limit). Not top priority.

Pick the amd card. Not only has it more firepower, it doesnt have "innovations" that slow down the speed of hashcracking. Radeon 6850 should also be twice faster than GTX 460.

Post: RE: Number of words in wordlist

... Did you notice 1/35 segment ? It splits the wordlist into 35 pieces, loads first, runs attack on it, flushes, loads second, etc.

Yes, 5870 > 6870. 2 * 6870 > gtx 480. Good estimations here (https://www.golubev.com/gpuest.htm)

OCLHC is designed for bruteforcing, mask and combination attacks. It is not designed to run simple wordlist attacks.

Since you have access to 0.24 oclhc, you can install any driver > 258.xx for the beta to work. This is the latest WHQL for your GT 220 (https://www.nvidia.com/object/win7-winvista-64bit-260.99-whql-dr...

No it cant. Try generating hashes of known plaintexts and then bruteforcing those hashes.
