hashcat Forum

I try to crack des hashes with oclHashcat-plus-0.08,but it seems did not display the GPU usage right,
and it seems not make the most of GPU,because of the temperature of the GPU did not rise to 90c.

With newer cards nvidia does not allow to read the gpu usage. This feature is restricted to the cad/development cards only.

but it worked fine in windows 2008

AFAIK NVidia removed support for fetching GPU utilization with ForceWare 260.x for non TESLA gpus on linux only.

got it,but the temperature did not arrive 90c(in windows it will arrive about 90c),the PLUS seems did not make the most of cpu.
How can I make the most of GPU in linux ?

Thank you !

From a GPU performance cracking-speed view there is nearly no difference from Linux to Window.

got it,thank you,atom.
