Mac Mini 2018 x86 擴充記憶體ＤＩＹ（混搭也可以用）upgrade DRAM with mixed sizes

Mac Mini 2018 x86 擴充記憶體ＤＩＹ，彈性很大（記憶體容量及速度要混搭，當然也可以用囉，效能沒有差很多，其實感覺不出來！）

Mac Mini 2018 x86 memory upgrade DIY offers a lot of flexibility (you can mix and match different memory capacity and speed, and it works just fine—performance doesn't differ much, and you probably won't even notice!). The best option is to keep one old 4GB DRAM stick and buy a new 16GB DRAM stick to use together, giving you a total of 20GB of memory. It's a cost-effective DIY memory upgrade method.

The final x86 CPU macmini with i5-8500B coffe lake family CPU. I need the dual OS system for family and daily routune work. I just bought a Crucial 16G DDR4 3200 DRAM module with NT$880. The origal Apple DRAM module worked on the speed of 2666MHz.

 I just find the i fixit website for DRAM DIY instruction by google search.

Ｔwo mico so-DIMM DDR4 2666 MHz memory slots

出廠預設 = 4GB+4GB = 8GB 2666MHz 由美光（Micron）提供的 DRAM，表面塗有黑色塗料。

Factory default = 4Gb+4GB = 8GB 2666Mhz by Micron DRAM coated black paint.

DIY 增加 16GB DRAM，需要移除其中一條 4GB DRAM，以釋放出未佔用的記憶體插槽。最終配置為 16GB + 4GB = 20GB（主機板僅有兩個記憶體插槽，因此我移除了原本的 4GB RAM），運行速度為 2666MHz。您最多可以升級至 65GB 的 DRAM。在測試期間運行良好。

DIY add 16GB Dram and need to remove one 4GB Dram to get an unoccupied Dram slot. Finally, 16Gb +4Gb = 20Gb (the MB only equiped two memory slots, I just remove the orgianl 4GB RAM) work at the speed of 2666Mz. You can upgrade maximium to 65Gb DRAM . It work well durin the testing peroid.
