This provided me with a total of 40GB when combined with the pre-installed RAM, which is more than enough memory for Final Cut Pro X, and whatever else I decide to throw at this 5K iMac. Feeling like 64GB is probably overkill for this machine, I opted for a 2 x 16GB DIMM package from Corsair. The entry-level machine comes with two 2400Mhz DDR4 SO-DIMM modules populating two of the slots with 2 x 4GB DIMMs. The 5K iMac features four DIMM slots, and can accommodate a maximum of 64GB of RAM. In this brief video tutorial, we’ll show you how. Thankfully, it’s ridiculously easy and relatively cheap to upgrade the 5K iMac’s RAM. With only 8GB of RAM, the system struggles right out of the gate, and will start writing lots of data to disk in fairly short order.

One of the weakest points of the base model 5K iMac has to do with its stock RAM configuration. In a nutshell, I believe that this machine, at $1799, is by far the best bang for your buck as far as Macs go. I recently acquired the base model Mid 2017 5K iMac, and I have a post in the works that explains my reasoning for that decision.
