hashcat Forum

I'm using the latest beta for tests with two GTX980TI's and see issues with using both cards.

Should the "--opencl-devices 1,2" flag use both cards ?

Using this command from the documentation:

./hashcat64.bin --opencl-device-type 2 --opencl-devices 1,2 -t 32 -a 7 example0.hash ?a?a?a?a example.dict

The output shows only GPU #1 with stats:

When I augment the command to use individual cards (i.e. "--opencl-devices 1" and/or "--opencl-devices 2") each card works without issue by itself.

Log for card 1 only:

Device #1: GeForce GTX 980 Ti, 1533/6135 MB allocatable, 1291Mhz, 22MCU
Device #2: GeForce GTX 980 Ti, skipped

Hashes: 6494 hashes; 6494 unique digests, 1 unique salts


Log for card 2 only:

Device #1: GeForce GTX 980 Ti, skipped
Device #2: GeForce GTX 980 Ti, 1535/6143 MB allocatable, 1291Mhz, 22MCU

Hashes: 6494 hashes; 6494 unique digests, 1 unique salts


Am I missing something else? If so just point me back to the documentation and I'll re-read it again.

Your help is greatly appreciated!

It uses both, just choose a larger wordlist
