  • It may not be as accessible as the (dead simple) RAM hatch found in the 27" iMacs—but still, this is a major win for upgradability over all the 21.5" iMacs with soldered RAM that we've encountered in recent years.

  • Before moving on, we take a moment to scope out the silicon these memory modules have to offer:

  • SK Hynix H5AN8G6NAFR-UHC 8 Gb DDR4 SDRAM (4 × 8 Gb = 4 GB per DIMM, 8 GB total)

  • Ablic (formerly Seiko Instruments) S-24C04A 4 Kb Serial EEPROM Memory

Quizás no sea tan accesible como la (muy simple) escotilla de acceso a la RAM encontrada en las iMacs de 27", pero aún esto es una victoria mayor para la capacidad de actualización sobre todas las iMacs de 21.5" con RAM soldada que encontramos en años recientes.

Antes de seguir, nos tomamos un momento para observar qué tienen para ofrecer esos módulos de memoria de silicio:

SK Hynix H5AN8G6NAFR 8 Gb DDR4 SDRAM (4 x 8 Gb = 4 GB por DIMM, 8 GB en total)
