GPU not utilised - srin2godisgreat - 10-07-2019 Hi, i am using the latest version of hashcat (v 5.1.0) , I have Win 10 i5-8300H Intel(R) UHD Graphics 630 and NVIDIA GeForce GTX 1050 Ti Now in Hashcat this seems to be the order OpenCL Platform #1: Intel(R) Corporation ======================================== * Device #1: Intel(R) UHD Graphics 630, skipped. * Device #2: Intel(R) Core(TM) i5-8300H CPU @ 2.30GHz, skipped. OpenCL Platform #2: NVIDIA Corporation ====================================== * Device #3: GeForce GTX 1050 Ti, 1024/4096 MB allocatable, 6MCU So i use the command >.\hashcat64 -m 2500 -d 3 try.hccapx D:\hackfiles\testingwpa.txt i have also tried the same command with " --force " but it dosent seem to work. From the output of the task manager and the status output of hashcat, it looks like only the cpu is being used. here is the output of running 1gb wordlist and its status >hashcat (v5.1.0) starting... nvmlDeviceGetFanSpeed(): Not Supported OpenCL Platform #1: Intel(R) Corporation ======================================== * Device #1: Intel(R) UHD Graphics 630, skipped. * Device #2: Intel(R) Core(TM) i5-8300H CPU @ 2.30GHz, skipped.

Thanks in advance. RE: GPU not utilised - Kryczek - 10-07-2019 As you can see at the beginning Hashcat skipped your integrated graphics and CPU but did not skip your GPU, then towards the end you can see it used your GPU at 90%.

RE: GPU not utilised - NoReply - 10-08-2019 Hashcat already told you some things you could try, which I quoted in bold here: (10-07-2019, 08:40 PM)srin2godisgreat Wrote: Session..........: hashcat Another thing which I noticed is that according to your CPU model, you are working with a Laptop. Note that Laptops in general are not recommended when running Hashcat for a longer time. Laptops, regardless of their "gaming" tag, are not designed to run on a 100 % GPU workload over longer periods of time.

I have no idea how you come to that conclusion. Hashcat clearly states that your GPU is being used. Code: OpenCL Platform #2: NVIDIA Corporation |
