Ram Specs - new 27" iMac

[zerae]

What are they?

I see the "1867 MHz DDR3 SDRAM" part. But what about the rest?

This post had some information: https://forums.macrumors.com/threads/ram-question.1928280/

But more specifically, I want to know what Apples sends you with a new machine, and what do I need to look for when trying to find compatible RAM? Which of things like registered/unbuffered, pin #, speed, CL, etc matter?

Here are some of the suggestions for things to buy, and I've been using the listed specs to try and piece it together:

1) http://eshop.macsales.com/item/Other World Computing/1867DDR3S32S/

2) Crucial Ballistix Sport 16GB Kit (8GBx2) DDR3 1866 (PC3-14900) 204-Pin SODIMM Memory BLS2K8G3N18AES4 / BLS2C8G3N18AES4


EDIT:

Based on the pictures here, it looks like This is the RAM that Apple Ships.

You can download the technical specs .pdf to get ~all of the information you could want.

I'd still be curious to know more about compatibility.

I found a review of the new iMac that linked to this from amazon as being the right ram for the new iMac. 1866MHZ ram I just ordered it. $88 for 16GB kit (8GBx2)

Where can I get 64GB of ram kit ?

Via OWC

OWC has 64GB for $1200 64.0GB DDR3 1867MHZ PC3-14900 Kit (16GB x 4) w/Lifetime Warranty – Double the maximum factory offered memory option. I am sure more will come that are cheaper.

I saw someone saying something about cheaper ram being found on amazon but they didn't post a link

Yeah that's nuts ill have to wait on that. Anyone know of any cheaper options ? I saw someone posted something about saying they found something on Amazon but no link was posted

That was me the link is: http://www.amazon.com/gp/product/B00DSGLMSM they have a few options.

Crucial itself is sold out right now. But they are more expensive at $99 over amazon at $88

What is the CL of those Rams? Can't believe Apple is charging a fortune for 32gb of cl13 ram

Can this be added to standard 8GB for 24 total? or does it replace it?

While I'm waiting for my top specced new 5K (sans RAM) to replace sweet old 2011 I'd like to know if anyone has an opportunity test if 5K works with DDR3L 2133Mhz RAM? I'm eyeing on the Kingston HyperX with CL11 which should be quite an update compared to the Hynix 1866 CL13 it has. I could always get faster 1866 but before doing that I really wanna know if the motherboard will support 2133 or will it be rolled down to 1866 after powering the comp.
