Will Crucial RAM work on an imac?

Question

Iron

I have an imac 27" (late 2015) core i5 3.2Ghz. There are already two 4GB RAM modules.
I'm looking at this option https://www.alser.kz/product/operativnaya_pamyat_c... It seems to be suitable in all respects, only for the original max operating frequency is 1867 MHz, and here it is 1600.
Does anyone have experience installing third-party RAM on imac?

Answer 1

put kingmax (more expensive) - the imac overheated and rebooted,
put on the advice of the seller the cheapest hynix - worked like a clock. Somewhere on the net I read that it was the hunix that was put de facto.
PS - it seems impossible to set a lower frequency, then higher bars can sag. I'm not an expert, but it's always advised to set bars equal in frequency.
+ There is a possibility that the declared threshold of the maximum amount of memory that comes to 1 bar is underestimated, and if you put in more capacious components, then everything works fine. I am writing from memory, when I googled all this

Answer 2

I have 4 x 4GB on my macbook 2012. The main thing is to choose the frequency

Answer 3

I took it to Ali Hynix. Flight is normal
