With the board out, the first order of business is inspecting the RAM.

There's no way around it: getting here was a major undertaking compared with the dead-simple RAM access hatch on the back of all previous 27" iMacs.

That said, we have a spot of good news: these are standard 288-pin DDR4 ECC RAM sticks, with standard chips on board:

SKhynix H5AN8G8NAFR-VKC 2,666 MHz DDR4

We waste no time in testing a little upgrade: How does four 32 GB modules for a "Maxxed" total of 128 GB sound?

After speedily reassembling everything, we're pleased to report that the result is epic. If you want to try it at home, pick up a Memory Maxxer RAM Upgrade kit.
