I have a August 2020 27" iMac that came with 8gb or ram
I am adding 2 more sticks of 8gb each=(16gb) for total of 24gb of ram.
Does the order in which the ram sticks are added matter?.
The existing two sticks of 4gb each are in slot 2 and 4.
Not really but the 9 to 5 website indicates that the old RAM (the 2 4gb Dimms) should be in slots 1&2 and the upgraded RAM should be in the 3&4 slots.
The 1&2 slots are the top 2, obviously 3&4 are the bottom slots.

9 to 5 recommends the original DIMMS should be in slots 1 & 2 (the top 2 slots) and the upgraded RAM in slots 3 & 4. If all the RAM is upgraded say to 64 gb and you use 4 x 16 gb DIMMS the obviously populate all 4 slots. However if you install 2 x 32gb DIMMS any themselves either slots 1&3 or 2&4 should be used.
Ram in 2020 iMac should not be installed in mixed pair. The original RAM (2 x 4GB DIMMS) should be in slots 1 & 2 (the top 2 slots) and the upgraded RAM should be in slots 3 & 4. I installed an additional 32GB of OWC (www.macsale.com) RAMl, please pay close attention the slots they are in and not the speed of each. Installing them way you asked would yield slower speeds.
Finally, iMacs are very sensitive to using quality RAM, only buy direct from www.macsales.com or crucial.com, DO NOT buy from resellers like Amazon, Ebay, etc.....
We do not think so but 9 to 5 website says that the older RAM (the two 4GB DIMMs) should need to be in slot numbers 1 and 2 and the newer RAM (the two 8GBs) should need to be in slot numbers 3 and 4.
The slot numbers 1 and 2 are on the top, the slot numbers 3 and 4 might be the bottom.
The 9 to 5 website strongly recommends the older DIMMs (the 4GBs) be in slots 1 and 2 and the newer RAM in slot numbers 3 and 4. If all RAM is updated (e.g. 64 GB) and you use 4x16 GB DIMMs they might use all 4 slot numbers. But if you use 2x32 GB DIMMs any of themselves either use slot numbers 1 and 3 or 2 and 4.
I have a August 2020 27" iMac that came with 2 X4 gb stick which = 8gb or ram
I added 2 more sticks of 8gb each=(16gb) for total of 24gb of ram.
and it worked well but I have alreday tossed out the 2x4gb and replace them all with 4 sticks of 8gb ram which equal 32gb of ram ,problem solved
