That's the way they are inserted. Could they have fried if they were inserted the wrong way?

What is the proper orientation? I've installed them with the printing the same orientation as the Boris 3 on the board and "upside down" from the board printing

I was told by Avolites the memory chip orientation didn't matter. As long as you don't mix old chips with new.
