Hello,

I own iMac 21,5 late 2012:
https://everymac.com/systems/apple/imac/specs/imac-core-i5-2.7-21-inch-aluminum-late-2012-specs.html

After HDD failure I am going to replace it by SSD (Samsung SSD 850 EVO 2.5" SATA III 250 GB).
If opening the iMac to replace HDD by SSD, I would like upgrade also my RAM. Installed RAM 2x4GB replace by 2x8GB.

Configuration about RAM used in iMac late 2012 is here:
https://support.apple.com/sk-sk/HT202625
But in this article is nothing about voltage (1,5V vs. 1,35 low voltage) and CL.

1. Is it important, what number of CL is in RAM?

2. Is it possible buy low level voltage RAM? Or dual voltage?


I could buy these RAM from other hand (2x8GB, same prices):

https://www.amazon.de/Hynix-original-204-pin-PC3L-12800-1600MHz/dp/B00ILWIAEW
In the bottom of amazon link is written that this RAM is suitablke for my model.
Backward Compatible with 1.5V DDR3 Memory module (source: https://www.skhynix.com/products.view.do?vseq=969&cseq=75)
Is it dual voltage?

or

CL=9. Is it compatible?
It seems to be dual voltage (?)

THANKS
