You never know 
You can running much slower XMP and check if it crashes - if yes, then it will be certain it’s not RAM.
Hi Guys
After researching for nearly 15 hours and following all the Blizzard & private guides on how to fix this issue i finally solved the issue.
The memory error 132 /Black/White screen is connected to your GPU drivers and Direct x 11 /12. In my case I have a RX 580 radeon, this problem can be solved by downgrading your GPU drivers and changing the WoW settings to Direct x 11 . For some reason WoW is currently installing the game with DX 12 has default. For those who are having this problem at “startup” without being able to open the game like me just do the following ;;;
open your …World of Warcraft_retail_\WTF… , open your (config.wtf) file with note and change the "SET gxApi “D3D12” to D3D11 and try to re run the game.
This will change the directx settings from 12 to 11.
Enjoy Merry Xmass !

this solved my issue, thanks! i guess the reason to that is that you need win10 for dx12 and i am running on win7
We were experiencing this issue for the past few days. It came to the point where we had to drop DirectX12 and use D11 instead which seemed to solve the problem (but for how long, I won’t know).
Have you found a solution to this? I have close to the same setup as you and the same problems
