Mac Pro 5,1 Issue

[15kitscs]

I trying to do the firmware hack and upgrade on mac pro. I was listening to what people said and tried to get cpu a fully working first. But the 3 and 4 lights keeps coming on for the ram even after reseating the cpu. Does anyone have any ideas on how to fix this issue?

You should not need to do any firmware hack on a 5,1.

OP has a 4,1->5,1, not a true 5,1, and also has other threads asking the same question.

OP, please don't start new threads when you have other ones talking about the same memory and CPU problems.
