Question

RAM

Hello!
I want to buy additional RAM for my Apple iMac 27 "Retina 5K A1419 (2017). Now there are two 4 GB dies from Micron (they came with a monoblock).
Here are the characteristics of the RAM in my monoblock:

If I take any die, to For example, this https://aliexpress.ru/item/33043957554.html, will it work in my monoblock or does Apple somehow limit compatible models?

Better find a used memory from iMac similar, you can remove one of the dies, look at the memory model number and search. In principle, the memory will be any, but there may be problems with stability. To a greater extent, you need to look for similar characteristics in terms of timing and frequency, well, or take at least frequencies no lower, because the memory will always work with the characteristics of the weakest bar, for example, if you buy a bar at 1200 MHz and, accordingly, with lower timings, then native bars also from 1600 will fall to 1200, iMac will work slower than now...
