Quote:The only card where this can happen is ATI/AMD of the 4xxx series. the 4xxx series did not support access to fast memory for the OpenCL interface, only for CAL. Since pyrit uses CAL it is faster on 4xxx cards. That changed with 5xxx and higher.
Not to hijack a thread but I'd love to then figure out what's limiting my ability!..
cudaHashcat picks up both my geforce cards:
Device #1: GeForce GTX 560 Ti, 1023MB, 1670Mhz, 8MCU
Device #2: GeForce GT 430, 1023MB, 1400Mhz, 2MCU
Using the -d flag, I can successfully isolate the process to use just the 560Ti (the better of the two). I have also played with -n flag, however any value above 8 does not yield an increase in computations per second.
