I have finally converted to the AMD side.

Using 2x 5850

1x MSI TwinFrozr HD5850
1x Sapphire HD5850

Oclhashcat-lite and oclhashcat-plus both work however oclhashcat fails to work. -Driver crashes BSOD etc
I do not have the cross fire bridges installed
The hashcats & MSI Afterburner are showing my shader clocks as 0Mhz is this normal??

Infact, I am a bit puzzled about the speeds I get for VB hashes in different modes.

My GPUs:

ATI Radeon HD 5870 (for oclhashcat only)
ATI Radeon HD 6770M (for both)

oclhashcat and mask attack as follows:

Code:
oclhashcat.exe -m 5 -n 160 --remove -o foundVB.txt vbulletin.txt -1 ?l?d?s wordlist.txt ?1?1?1?1 --increment
The speed of cracking is: 137.9 Mhashes/s

There are 8 VB hashes in vbulletin.txt with a 3 char salt.

I tried on another GPU: ATI Radeon HD 6770 M and got a speed of 29 Mhashes/sec.

Now, with oclhashcat-plus

These stats are with ATI Radeon HD 6770M

Code:
oclhashcat-plus64.exe -m 5 -n 160 --remove -o foundVB.txt vbulletin.txt wordlist.txt

With this Dictionary Attack, I got: 41993.2k c/s or 41 Mhashes/sec

Now, after applying rules to the attack:

Code:
oclhashcat-plus64.exe -m 5 -n 160 --remove -o foundVB.txt vbulletin.txt wordlist.txt --rules=T0XlC.rule

228 Mhashes/sec

Now, the way I see, it's an extreme under utilization of the GPU in the case of oclhashcat with a mask attack.

I understand that by selecting more rules and applying them to a decent size wordlist, the amount of computations done by GPU increases, but is there a way to replicate the same effect in the case of a bruteforce or mask attack too?

The above benchmarks clearly depict that there's a huge margin of difference in the speeds obtained in different modes and with different programs. It would be great to simulate the same effect in oclhashcat to better utilize the computational power of GPU.]]>

is there a possibility of having support for an --stdout option in the next release of oclhashcat?

this --stdout option would print the list of word combinations being generated by oclhashcat

At present, we have oclhashcat and oclhashcat-plus as 2 separate programs. there's no option to bruteforce or mask attacks in oclhashcat-plus. To combine the 2 features I wanted to use the --stdout option to pipe output of one program to input of another.

I have already tried the mask processor, mp64.exe, but it doesn't utilize the speed of the GPU quite well. It is possible to run multiple instances of oclhashcat-plus, however, it still doesn't give good results.

just wanted to know the feasibility of this.
