CL_OUT_OF_HOST_MEMORY

[calypso2024]

Hi.
I got troubles trying 15700 algorithm on Intel Xeon CPU E5-2696 v3.
Any attempts results with CL_OUT_OF_HOST_MEMORY.
I have Win10 and RAM size is 32GB.
So I try hashcat.exe -I and this what I got (Memory.Free....: 0 MB).
Kindly help.

hashcat (v6.2.6) starting in backend information mode

Failed to initialize NVIDIA RTC library.

Looks to be an issue with OpenCL Drivers. One portion shows version 2.1 (build 0) and other shows Open CL 2.0. So might have to reinstall the proper OpenCL drivers for Intel Xeon Processors.


Otherwise, if you limit the attack to use strictly your GPU by using -d 1 does the attack work?

Hi. Your idea was right.
I uninstalled all Nvidia and Intel OpenCl software. Cleaned up the registry.
Then replaced the video card with a Radeon.
Installed Intel OpenCl (w_opencl_runtime_p_2021.1.1.1.191.exe) and everything worked fine.
The previous system based on Intel Core i7 5820K gave 19H/s for 15700.
The current system based on Xeon E5-2696 v3 gives 28H/s.
There is room for improvement I hope.
Thanks for your help.
