There are five different logic boards for the MacBook Pro (Retina, 15-inch, Mid 2015). 2.2 GHz2.5 GHz2.5 GHz with dual graphics2.8 GHz2.8 GHz with dual graphics Can I replace a bad 2.2 GHz board with a 2.5 or 2.8 board? Swap an integrated graphics for dual graphics? Are they interchangeable?
There are some differences between the IG models Vs the DG models logic boards as the IG models only have one fan and the DG models have dual fans. I would stick with the same graphics model (IG vs DG) your system is as being the simpler direction. If you have a IG model you still can upgrade it to a DG model. But you’ll need the second fan as well as a different heat sink and gasket.
@yourmacexpert yes you can for as long as it is the same series. The boards you listed (Can I replace a bad 2.2 GHz board with a 2.5 or 2.8 board) will qualify for replacement.
I have 2 Mid 2015 MacBook Pros. One is the top-tier Mid-2015 - 2.8GHz 16GB with AMD Radeon R9 M370X 2048 MB / Intel Iris Pro 1536 MB. It’s in poor shape, with a cracked screen. The other is also a Mid-2015 - 2.2GHz 16GB MJLQ2LL/A (2.2 GHz) with Intel Iris Pro 5200. It’s in almost perfect shape. If I understand Dan’s reply, is there any reason that I couldn’t take the logic board along with the second fan and heat sink from the one with the cracked screen and put it in the other one?
