Re: Cuda/CAL VS OpenCl.

Some posts by the pyrit dev seem to indicate that with ATI cards, pyrit runs faster on OpenCL. However, there is not many benchmarks at the moment. I did some tests with pyrit, nvidia-cards and OpenCL, but there seems to be a problem somewhere. Maybe in the setup, maybe somewhere else, but performan...

Is there any reason that speed varies so much between cores? Those systems were all idle otherwise.

Re: BarsWF in a german pc magazine

Ok, here we go - something about the hardware: Nvidia QuadroPlex S4 : Using this for password cracking is pretty pointless - we were only able to access two GPUs of the system, after swapping/trying different nvdidia drivers half a day. One GPU of the S4 just made 398 million MD5 per second. As far ...

The article shows what happens when password hashes, based on current policies, fall into the wrong hands - hands that have access to a GPU. BarsWF is used to show the readers what the difference in performance between CPU- and GPU-based cracking is - pitting a GTX 280 against a system with four Int...

Use the 8.12. The 9.1 doesn't work for me too. It works with the 8.12 catalyst drivers. However, using set BRT_ADAPTER=1 nets this: http://img100.imageshack.us/img100/4656/4850x2adapter1ir8.png Using set BRT_ADAPTER=0 or not setting it all will let it run nice and smoothly at around 890 MHash/secon...

there've been a lot of topics about that. but they have nothing to do with real life mostly.
In real life it seems more cost effective to put four cards in two computers and save quite a few bucks - and cooling problems.

Re: Video Card upgrade

If you want to use two cards, take care of the kind of 9800GTX+ you're getting. The "open" ones, with two fans attached are a pain to cool, unless your case has big fan on the side. If possible, get those with an enclosure/case. Else those cards will heat up each other a lot - remember, you might ru...

Re: WPA support

There's an opensource project around, called pyrit , it provides the speed for quite a number of cards right on the front page. It does around 10k on a GTX260, a bit more than 11k on a GTX280. However, Aircapture claims they can do 75000 on a single FPGA and build systems with up to 210 FPGAs. 1.5 b...
