| - | [* black] With the logic board out of its case, we quickly dispatch a few Torx screws to free the RAM from its cage. |
|---|---|
| - | [* black] We've seen this kind of thing before in [guide|17828|iMacs of yore|stepid=52541|new_window=true]. This shield allows the RAM to operate at high frequency (2666 MHz) without interfering with other functions. |
| - | [* black] At last, we get our hands on that replaceable RAM! |
| - | [* icon_note] Sure, RAM access has [guide|11262|been easier|stepid=40350|new_window=true], but this is still a big win over the soldered RAM we've seen lately. |
| - | [* black] With the logic board de-cased and the RAM de-caged, the two SO-DIMMs come right out. |
| - | [* icon_note] These are SK hynix [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. |
| + | [* 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. |
