Yes, 204 pin and 240 pin really make huge huge difference on price. That is irritating!
Lol. I am not having a good day. You're quite right. It is 240 pin. I am going to shut up now.

theSeb: Do you have any experience with mixing RAM from different brands? What might happen if you mix let's say the Apple CL11 RAM with the Crucial CL11 RAM? I hope nothing fatal because I think I'm going to take the risk.
Nothing fatal at all. It might simply not work. So the computer might not boot or you may only see half of the capacity. These things are not 100% this way or that way and hence why I use the word "might". In all likelihood it should work, but it does not always work hence why I always include a disclaimer. But to be more specific, there is a higher chance of it working than not working.
I am undecided on returning it , or just buying another 16gb as this ram is better than the stock, better timings etc.)
I think I'm better off trying to get the same ram as Apple used (Hynix) if I can though.
No. You only need that RAM if you're planning to add it to the stock RAM. And even then mixing different brands is not a good idea. Buy the RAM that you can afford that meets these specifications:
PC3-12800
(1600) DDR3
204-pin
SO-DIMM
It's best to buy the same sticks from the same manufacturer. 1600 MHz CL9 RAM will be faster than 1600 MHz CL10 RAM which will be faster than 1600 MHz CL11 RAM.
The really interesting question is how will the motherboard handle 1866 MHz CL10 RAM.
----------
You're looking fine, but you could have bought faster RAM. Real world difference? Not something that you would really notice.
I will buy someone's apple RAM that they have replaced. PM me.
Can I ask a possibly dumb question on this?
If the faster RAM is 1600mhz CL10 and the Apple RAM is 1600Mhz CL11, why does the clock speed drop to 1333Mhz in this situation?
I'd have expected the faster RAM to fit in with the slower speeds of the CL11 RAM

Edit:
It will work just fine.
Thanks Seb, guys so this is C11 and would definitely not underclock with apples RAM right? I'm just double checking as I've bought the wrong memory already. I anybody has it and can confirm please do so.Checked ifixit website. 21.5 ram is CL11. Assuming for now same us true for 27. Those with Crucial ram upgrade should be good to go.

That crucial ram looks to be ok with the apple ram. I would purchase crucial ram from crucials website if u can ( cheaper and direct from source).
Strictly speaking, MacRumors frowns on buying and selling on their forum. They probably don't want to get stuck in the middle of a bad deal, or be overrun with Creigslist type adds.

Are you running the crucial and apple ram together?
Has anyone else given the crucial and apple together a go?
Sorry, new here. I edited my post. Thanks for letting me know.
Apple doesn't manufacture ram, so it will be ram from one of the major vendors. It could be Crucial ram. Apple claims they test it to spec, and I haven't seen bad stock ram out of the box. With anything I purchase off the net, I test prior to any real computing. It's just safer that way, regardless of what brand you purchase.

Sorry mate. I am not following you here.Are you referring to latency or actual MHz? Isn't it 1600mhz?

Apple normally uses RAM made by Hynix, but Crucial claims that Apple uses their memory as well...
Crucial is a subsidiary of Micron so it uses Micron memory.
They tend to sell directly to OEMs and phone makers. I am not sure if they even sell anything branded as Micron directly to consumers, since Crucial is apparently "Micron's memory upgrade division".I know Micron owns Crucial. I just haven't seen any ram with Micron branding in a long time. I don't know if they still sell any under their own name. Apple rebrands whatever they're using, but I didn't know they primarily used Hynix.
Good to know. Either way, I'd love to know what's going on here since I'm going to be using this very RAM in my soon-to-be-delivered iMac.
