Dear Colleagues
I want to upgrade memory from 2x4GB to 2x16GB (or 4x8GB) with my iMac. Unfortunately listed as compatible RAM modules are not available anymore. I need a little guidance which type (from currently being available) I can use.
Thanks for support
Regards,

You are right! I looked to the wrong table!
Get memory specifications for iMac (Retina 5K, 27-inch, Late 2015), then learn how to install memory in this model.
Memory specifications
This iMac model feature Synchronous Dynamic Random-Access Memory (SDRAM) slots near the bottom of the computer with these memory specifications:
Number of memory slots | 4 |
Base memory | 8GB |
Maximum memory | 32GB |
Use Small Outline Dual Inline Memory Modules (SO-DIMM) that meet all of these criteria:
Macs are fussy about RAM, use only high quality memory modules. OWC (which CountryGirl pointed you to) or Crucial are two trusted vendors.
Crucial has a 45 day money back policy

OWC has a 30-day return policy on OWC branded RAM.

EDIT: I was posting when you posted that you are in Europe.
My problem is how to find newest one however compatible with Apple
Specification is:
PC3-14900 - > not available anymore
Unbuffered, Non parity, 204-pin -> this is not a problem -> standard
1867MHz -> probably higher frequency shouldn't be a problem
DDR3 SDRAM -> standard
One option… RAM Upgrades for iMac 27-Inch (2012 - Mid 2015)
Thanks! At least I know what I'm looking for. Unfortunately can't buy it from there as I'm located in Europe (EU Customer would charge me 23% of VAT at least on top!)
You're welcome. I don't know where to shop for RAM in Europe but the Memory Modules themselves shouldn't be difficult to find.
Not sure what you mean. Those are not the RAM specs for your machine.
OWC, the place CountryGirl linked has a UK partner:
