2020 iMac 27" RAM Upgrade Question. Are all "2666Mhz" RAMs automatically "PC4-21333"
I'm a new iMac owner (and it's also my first computer that I bought for myself) and have minimal experience in upgrade parts. So I'm confused if there might be incompatibility issues with "2666MHz" rams?
This DDR4 - 2666Mhz ram has a label PC4-2666V so I wonder if that is incompatible? or all SO-DIMM DDR4 - 2666Mhz rams (260-pin) are automatically compatible with the last intel iMac?
This is the most "compatible" RAM I've seen in my country's online stores that also fits my budget, and I just worry that it might be incompatible or not optimized for my 2020 iMac.
Thanks in advance
