Do I need different RAM for new logic board?

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!

Thank you. The replacement logic board is not the same. Previous board is a 2.2Ghz i7 and the new is a 2.4Ghz. According to Crucial.com the same model of RAM is compatible with the following processors:

2.2GHz, 2.4GHz or 2.5GHz Quad Core Intel Core i7 processor.

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.
