I am buying an iMac, for which Apple says the criteria is PC4-21333 2666MHz DDR4-SDRAM
On Amazon, all of the 2666MHz DDR4-SDRAMs are mentioned as PC4-21300
I could not find a comparison or difference between these two anywhere. The closest info I have is below.
PC4-21300 from
https://en.wikipedia.org/wiki/DIMMPC4-21333 from
https://en.wikipedia.org/wiki/DDR4_SDRAMThe first link is about DIMM and the second one is I think the production version of SDRAM 2666MHz RAM.
So are they both the same? Also the Memory clock is very different between both the wiki pages for PC4-21300 and PC4-21333
Any insight on this?
