Very very smallest the cracking speed 7870 XT - loveistheair - 12-29-2014 I have GPU 1 Ati Radeon HD7870 XT With Boost (Tahiti core 7950/2 ( share on 2) = my 7870) Program to recover WPA/WPA2 passcape and elcomsoft give me speed about 120000-160000 pass/s oslHashCatGui give me 49312 pass/s Seems there in oclHashCat is a special limitation on the graphics card How to remove this limit and who made it and for what??? 2 And anyway very small speed on all card less than other programs (passcape and elcomsoft ) on 5000-10000 pass/s How to contact the developer on this subject? RE: Very very smallest the cracking speed 7870 XT - epixoip - 12-29-2014 First, there is no "special limitation." Second, those other programs are lying to you. Your GPU has 1536 cores @ 975 Mhz, and WPA2 has ~ 14000000 instructions. Therefore the theoretical maximum performance for your GPU is: 1536 cores * 975000000 Hz / 14000000 instructions =~ 106.9 KH/s To get 160 KH/s out of your GPU you'd need a clockrate of ~ 1458 Mhz, which your card cannot support. Third, you've not posted your command line or even specified the attack you are running to obtain this number. Try running "oclHashcat64.exe -b -m 2500," it should be around 100 KH/s. If so, there is something wrong with your attack. Maybe you have a very high rejected rate due to testing mostly candidates that are less than eight characters.

RE: Very very smallest the cracking speed 7870 XT - epixoip - 12-29-2014 This is likely your problem: Quote:-w 2 --gpu-temp-retain 45 Get rid of --gpu-temp-retain and use -w 3. Your 7870 is also clocked at 725 Mhz instead of 975 Mhz, so that's another problem. For benchmark mode your command is incorrect. Your command should just be simply "oclHashcat64 -b -m 2500" Quote:Where can I find a description of all key commands? "oclHashcat64 --help" or read the wiki page http://hashcat.net/wiki/doku.php?id=oclhashcat RE: Very very smallest the cracking speed 7870 XT - loveistheair - 12-29-2014 with command oclHashcat64 -b -m 2500 I have log....

Thanks for the help you are a professional))))I am a beginner... RE: Very very smallest the cracking speed 7870 XT - epixoip - 12-29-2014 Ok, so with the proper workload settings you're getting 102.7 KH/s - 103.3 KH/s with your 7870, which aligns perfectly with the theoretical max performance of 106.9 KH/s. Therefore oclHashcat is quite optimized for your card, and you can see there is no limitation here. There's no such thing has a 5990, that card does not exist. Maybe you meant a 5970 or a 6990. Either way, there's not much difference between 95 KH/s and 98 KH/s. Cracking speed is rarely constant, and 3 KH/s fluctuation is normal. Don't stress over this. Based on the output you posted, everything here looks completely normal. |
