| [* black] With the board out, we're going straight for the RAM. Apple has trapped it in a heavy metal cage—almost as if they don't fully trust modular RAM to behave itself. | |
| [* icon_reminder] Actually though, we've seen this in [guide|17828|iMacs of yore|stepid=52541|new_window=true]. The shield allows the RAM to operate at high frequency (2666 MHz) with no chance of accidentally interfering with other functions. | |
| [* black] Twirl away four Torx screws, and the cage slides right off. Has RAM replacement ever been easier? | |
| [* black] [guide|11262|Sure it has|stepid=40350|new_window=true]—but, the return to standard SO-DIMM RAM after the bitter disappointment of the [guide|30410|2014 mini's soldered-down chips|stepid=71241|new_window=true] is a huge win. Upgrade now, or upgrade later—you have a choice again. | |
| [* icon_note] We pop out two SKhynix [https://www.skhynix.com/products.view.do?vseq=2408&cseq=75|HMA851S6CJR6N|new_window=true] 4 GB DDR4-2666 SDRAM modules, each with four 1 GB [https://www.skhynix.com/products.view.do?vseq=2376&cseq=73|H5AN8G6NCJR|new_window=true] DDR4 SDRAM ICs. | |
