hashcat Forum

I try to use hashcat (V5.1.0) on AWS (p2.xlarge)

it complains
* Device #1: This hardware has outdated CUDA compute capability (3.7).
             For modern OpenCL performance, upgrade to hardware that supports
             CUDA compute capability version 5.0 (Maxwell) or higher.

but using hashcat -I I have
Platform ID #1
  Vendor  : NVIDIA Corporation
  Name    : NVIDIA CUDA
  Version : OpenCL 1.2 CUDA 10.0.292 <---------------- not 3.7 :-(

  Device ID #1
    Type           : GPU
    Vendor ID      : 32
    Vendor         : NVIDIA Corporation
    Name           : Tesla K80
    Version        : OpenCL 1.2 CUDA
    Processor(s)   : 13
    Clock          : 823
    Memory         : 2860/11441 MB allocatable
    OpenCL Version : OpenCL C 1.2
    Driver Version : 410.104

why ?

Thanks for helping me

The K80 only has compute capabilities up to 3.7. The number you pointed at is the OpenCL version number and the CUDA runtime version number, not the limited capabilities of the card. The card lacks the LOP3.LUT instruction set introduced in Maxwell and therefor is far less efficient/performant for hash cracking. Choosing the g3 or p3 instances from AWS would be a far better use of your money.
