620 graphics on Dell 3853

Hi there, I'm trying to fix my laptop here, and I'm having some troubles getting full acceleration on my laptop. I have High Sierra installed, but that pesky RAM isn't showing up and acceleration is working.
I have read over RehabMan's guide on how to get it to work, and I even tried to use his plist file, but it ended up giving me a black screen while it booted.
I have placed Whatevergreen, FakePCIID_Intel_HD_Graphics and Lilu in /L/E, but no dice. If anyone has any suggestions, I would be eternally grateful!
