Frustratingly this was originally in a fully working and tested console I decided to serviced the console to help with longevity, and unknowingly to me my Delid tool had a little chip in it, which meant a circle was scratched all around the cpu (pictures shown, but after I had added some uv mask when I was still hopeful it would still work. Unfortunately when put back together the console showed YLOD. So this is a perfect donor board for otherwise working components! Also includes paired disc drive board.
