New life to older Mac
2 of 2 found this helpful Relatively easy swap out for older, slower CPU in my 2009 Mac Pro 4,1 flashed to 5,1. Now my 9-year-old system is good for several more years! Plenty of videos on YouTube to guide you through flashing your firmware and then physically replacing the CPU.
