Sorry I'm not all that tech-literate, so would just like to make sure I'm not buying the wrong thing before going ahead. Looking to upgrade the RAM on my iMac (Retina 5K, 27-inch, 2020), that currently has 8 GB 2667 MHz DDR4. Is there any meangfull difference between these options that I should be aware of before buying?

Hello and welcome.

Your iMac (Retina 5K, 27-inch, 2020) has four slots that support a maximum of 128 GB of 260-pin PC4-21333 (2666 MHz) DDR4 SO-DIMM memory.

I am a huge fan of OWC and have purchased many RAM upgrades from them. I can recommend their products highly. So, the link to the OWC is the way I would go: https://www.amazon.co.uk/OWC-Matche...1300/dp/B07PTRZSHB?ref_=ast_slp_dp&th=1&psc=1

Hope that helps!
