Hello Milinko, I was down to about 2 seconds per burst using just 3 * Radeon HD 6990, 5*480GB SSD:s, and 24GB RAM (and there was really no need even for 24GB). I used the a5_ilx driver and not the a5_ati one (this makes a big difference), and made some minor enhancements to the Kraken code. So, I don't think you will need to throw that amount of hardware on this to reach your goal. ;) I made most of my experiments with Kraken about three years ago btw..
Note that newer AMD-GPU:s might not be compatible with Krakens a5_ati/a5_ilx drivers btw. AFAIK, 6990 is the latest one that is guaranteed to work. If anyone has managed to use newer AMD-GPU:s than the 6990 with the Kraken code, I would love to know about it. :) Cheers, Joel On Mon, Sep 8, 2014 at 6:08 PM, Milinko Isakovic <[email protected]> wrote: > Rajat, > > May you please try to crack with ATI Radeon r9, as before I get few of > them, I would like to have confirmation this will work :) 16 of this cards > will cost about 8.000 us$, I don't want to buy them if there will be no > chance of useage :) > Regards > > > > On Mon, Sep 8, 2014 at 3:37 PM, Rajat Swarup <[email protected]> wrote: > >> I have seen desirable power/performance results with ATI Radeon r9 290x >> but I am just using 2 of those (using hashcat, not for a51 cracking but for >> general password cracking). >> >> I think overall openCL based ATI cards seem to do really well compared to >> CUDA cards. >> >> Hope it helps. >> >> -Rajat. >> >> On Sep 8, 2014, at 4:59 AM, Milinko Isakovic <[email protected]> wrote: >> >> > >> > >> > Hi guys. >> > >> > I would like to make extra fast machine for cracking. >> > My idea is to use: >> > >> > 1.
