I plan on doubling the RAM but I’ve seen two different videos to do that. I’m wondering if I have to put the new RAM in any special order. Does it matter?

When I self upgraded my 2017 iMac, I installed the two 16GB sticks in the two(of four) open slots.
Believe it was 1 and 3, with stick being in 2 and 4.

Ive seen reports for the 2020’s not playing well with self installed, so your results may vary.
I plan on installing my RAM in the empty slots as I did in 2017.
If that does not work I’ll open it back up, pull the stock 4’s and install my 16’s in those slots....

From my 2017 install, the green are my Crucial upgrade kit:

I bought a pair of Crucial RAM as well. However I removed the original 8GB RAM (also has the Micron branding) entirely.

Built and Ship times seem rather quick vs when I bought my BTO back in 2017.

I ordered my 27" iMac with i7, 8 GB RAM, 1 TB SSD, 5700XT, 10 Gb Ethernet, Trackpad, Extended Numeric Keypad KB with AppleCare+ on Saturday, August 22, 2020 at 11:39PM EST.

It's already shows that it is Preparing to Ship as of Tuesday, August 25, 2020 at 2:00PM EST!

I read some posts here saying that the SSD, 10Gb Ethernet may hold up production but 2.5 days isn't too bad from payment to shipping for a BTO unit. I am sure the trip from China will take a week or so but my guess the original expected delivery date of Sept. 9-16 might be a bit conservative.

This is the situation as I understand it:
The 9to5 youtube on the subject suggests:

1. Apple 4
2. Apple 4
3. Crucial 16 (or whatever third party manufacturer and size)
4. Crucial 16 (or whatever third party manufacturer and size)

This gets you full speed but you lose dual channel support, which will incur a performance hit.


Alternatively
1. Apple 4
2. Crucial 16 (or whatever third party manufacturer and size)
3. Apple 4
4. Crucial 16 (or whatever third party manufacturer and size)

...will get you slightly reduced speed but retains dual channel support.

It's not clear to me which is worse and WHY, but from what I have gathered— the better alternative of the two is retaining dual channel support. It follows then, that if you ordered an iMac with 8 gigs of ram with in conjunction with a couple of larger third party sticks you might be better off selling the native sticks and just put the aftermarket ram in slots one and three. Due to the almost overwhelming amount of misinformation out there it took me WAY to long to arrive at this conclusion and even now I wonder if I have it right!

We ordered 2 exact same iMacs on 8/11

27-inch iMac with Retina 5K display

Hardware:
  • 3.6GHz 10-core 10th-generation Intel Core i9 processor, Turbo Boost up to 5.0GHz
  • 8GB 2666MHz DDR4 memory
  • 1TB SSD storage
  • Radeon Pro 5500 XT with 8GB of GDDR6 memory
  • 10 Gigabit Ethernet
  • Nano-texture glass
  • Magic Mouse 2
  • Magic Keyboard with Numeric Keypad - US English
Oddly, our card showed the full amount pending over the weekend when the status changed, but as it turns out only 1 was charged and only 1 is marked shipped. The other is still processing which seems weird.

Original arrival was Sept 2-10. The one that has shipped shows it's arriving the 31st, the other still shows processing is still showing the original arrival.

it's shipping from China...

I ordered a similar spec around the same time on Aug 22 and also showed "Preparing to Ship"! The only difference is 2TB SSD vs 1 TB SSD.

This is my second 2020 iMac. I returned the first one to upgrade from 5500XT to 5700XT. The first one took about 10 days before showing "Preparing to Ship".

Thanks for the info. It is coming with 16GB but I thought I would double that. Sounds like I may want to just order 32GB from OWC. I added RAM to my 2011 with no problem, so hope this will be the same.

I ordered identical specs to GreenDice, but ordered it 4 days earlier. Mine just changed to preparing to ship. So the 2.5 days you experienced is extremely fast.

Everybody that has tried has confirmed that the Apple ram does not work properly with other brands. So just order from OWC or similar at once. You will absolutely experience the same.

Mine went from Sept 10-17 to Sept 8-15 now to Sept 2 (according to Apple). It left Shanghai today. UPS says August 31. Yay!

Same here, except Apple originally said Sept 1 for me. UPS said August 31 as soon as it escaped Shanghai, with no estimated delivery before that.
I’m secretly hoping it makes it for this weekend though.

If anyone needs a timeline: Ordered August 20th (27' mid range w/ 1TB SSD + 10 Gb ethernet) and will be delivered September 3 to Canberra, Australia.

Cancelled order before it arrived for the same model except VESA mounted, which I didn't know was a thing.

Ordered mine a couple days ago:

10 core i9
8GB RAM (+ 64GB RAM from OWC/MacSales)
1TB SSD
Radeon Pro 5700XT 16GB

I run a design/dev studio and photography. Work with 47MP RAW files from a Nikon D850, Photoshop, Web Development, and also Audio Engineering so I think this baby is going to do just fine.

Upgrading from 2017 iMac 4-core 4.2Ghz i7, 40GB RAM, Radeon Pro 580 8GB 512GB SSD.
