The GPU in my logic board went bad in my 2011 MacBook Pro 15 for the 2nd time (2nd logic board). So, I decided to purchase a new logic board and install it. The old logic board was a 2.2 Ghz Intel Core i7 with 16GB RAM. The new board is a 2.4 Ghz Intel Quad-Core i7 and I put the existing RAM in the new logic board but I am wondering if I need different RAM since the machine will not boot up… Can anyone help me know if I need new RAM or if the old RAM should still work? Thanks!
Hi @lballew73 If the replacement logic board is the same model as previous, RAM should not be an issues. Test by installing One RAM at a time.
