Why is there any allocated memory difference between 6.2 2 versions with 6.2.5?

[Snoopy]

Code:

OpenCL API (OpenCL 1.2 )

this is really old and you will run into some troubles using these old opencl api with hahscat

next thing opencl on intel iGPU is broken by default

you have to! (plz just believe me)

deinstall intel hd graficsdriver with windows programs (it is there) and install 
*ttp://registrationcenter-download.intel.com/akdlm/irc_nas/vcp/13794/opencl_runtime_18.1_x64_setup.msi

this will install opencl runtime 2.1 for cpu only (the speed will be the same) due to the combined cpu/gpu architecture

see whole thread here for more informations
https://hashcat.net/forum/thread-10548.html

the only thing to be aware of, you have to add at least

Code:

-D1

to your command line to tell hashcat to stick to your cpu

after de- and installing see output of

Code:

hashcat -I 

telling your cpu with opencl 2.1
