Newbee Question about Requirements(RESOLVED)

This question is not the same as my other, This is about Requirements for Hashcat & OpenCl.

Goto bottom of thread to shorten your reading..




Hi all, iv recently setup my (ahem) Cracking rig, 

But iv got a little complication and not sure about the requirements for hashcat..



My card is an

So from what i can make out and after reading other peoples threads WITH THE SAME CARD/ ISSUES (RESOLVED)

My card is compatible for hashcat.

However i am having difficulty understanding the requirements for hashcat




GPU Driver requirements:

• AMD GPUs on Linux require "RadeonOpenCompute (ROCm)" Software Platform (1.6.180 or later)
  
  
• ***AMD GPUs on Windows require "AMD Radeon Software Crimson Edition" (15.12 or later)***
  
  
• Intel CPUs require "OpenCL Runtime for Intel Core and Intel Xeon Processors" (16.1.1 or later)
  
  
• Intel GPUs on Linux require "OpenCL 2.0 GPU Driver Package for Linux" (2.0 or later)
  
  
• Intel GPUs on Windows require "OpenCL Driver for Intel Iris and Intel HD Graphics"
  
  
• NVIDIA GPUs require "NVIDIA Driver" (367.x or later)
  

So My Question is 

1. Do i need OpenCl , as i have a GPU on window AMD radeon crimson


2. Where does Open Cl come into it 
( I know its supposed to be a OpenCl compatible gpu or sumthing, But im just not sure as to the openCl part)

3. How does OpenCl have anything to do with my GPU. I can download OpenCl for my OPSYS , But my graphics card is driver dependent for OpenCl, So what openCl does my graphics card have to have to be compatible... 

4. what is AMD OpenCL SDK



And how is it that other people with same card have got it running with hashcat, allbeit older versions or with a few tweaks here and there so to speak..


Thanks for any advice.
