Well I have read and tried every single thing in this thread now including things that really have no chance of working for my machine. I'm come to the conclusion that there is not a solid answer. I have decided to go back to mountain lion.
I have a good 8-10 hours of effort put into this install and it's just a no go. For those like me who are having this problem and reading through every single comment to try and find a solution I have a few things to add:
1.)
https://discussions.apple.com/thread/6600995 This thread says that this is an issue happening with legitimate apple computers as well. It suggests using OEM apple memory. I don't have it to test but maybe it will help someone.
2.) Here is my specs z77x-ud3h Gigabyte, 16 gigs corsair ram, 480gig crucial ssd, i7 3770k intel
More specifically things that I did
Tried 4 different USB sticks. Two 8s and two 16's
Totally uninstalled unibeast, multi beast, and the actual yosemite os and reinstalled and reformatted usb's and set them up 3-4 times each and tried.
Tried all flags in this thread most specifically -no-zp -x and all combinations including graphicsenabler=yes even though I don't have an old graphics card.
Tried preparing the USB with GUID instead of Master Boot Record.
Tried with my GPU plugged in and with it unplugged.
