When i crack a burst with the Radeon HD 5870 (1GPU) it is faster than using the Radeon HD 5970 (2GPU). I expected the the HD 5970 doíng the job in half of the time. Can anyone tell me what is wrong?

I have the rainbow tables written to HD and everything seems to be working. I tried this tutorial: http://lists.srlabs.de/pipermail/a51/2010- July/000688.html and everything worked nicely but when I try to run kraken on my own bursts I can't seem to get them to crack no matter which burst I pick. Here's what I'm doing: 1) Use airprobe to decode unencrypted SACCH packets to a text file and view them in wireshark Exported packets look like this (System Information Type 5): C1 862242 1332356: 00100000000111000010000000110010001100000110000011000000011010100100000010101001 0001001000110100000000101000000110 P1 862242 1332356: 00100000000111000010000000110010001100000110000011000000011010100100000010101001 0001001000110100000000101000000110 S1 862242 1332356: 00000000000000000000000000000000000000000000000000000000000000000000000000000000 0000000000000000000000000000000000 C0 862243 1332389: 000000000</pre> Alex 2013-03-06T23:22:09 http://comments.gmane.org/gmane.science.cryptography.a51/1206 <pre>Hi, Can anyone give me a basic tutorial of how to run Kraken or point me to some documentation? I've got the 40 rainbow tables that are available via torrent I'm just somewhat confused as to how to actually use the utility.

I'm wondering if anyone would be able to do me a big favour and upload these missing files to my server, I'll obviously pay you for your time. cheers Chris _______________________________________________ A51 mailing list A51-Gjhu/N1EzaPLZEeaCYvZmUEOCMrvLtNR&lt; at &gt;public.gmane.org http://lists.lists.reflextor.com/cgi-bin/mailman/listinfo/a51 </pre> 0 0 2013-02-08T20:44:50 http://comments.gmane.org/gmane.science.cryptography.a51/1201 <pre>There is someone that can send a hard disk with rainbow tables in Italy?
