I purchased my 2013 27" 2.9GHz i5 iMac when it first was available to pre order, at the time i could only afford the model with 8gb of memory. I now am looking to add more memory (ideally another 8gb) but rather than aftermarket i want to use the genuine apple memory exactly the same as what is installed in the machine already.

Does anyone know where the best place to get the memory from at a good price? Perhaps someone here has removed the 2 x 4gb ram to replace with larger and is willing to sell?

Any info or help is appreciated.

For Apple memory, you'd have to purchase from Apple. And even then, there's no guarantee you will get the exact same memory that is in your machine - Apple uses Hynix and Samsung for their memory suppliers.

As for Crucial memory, I've never had a problem with them. Just make sure that you are using memory from the same brand/manufacturer - don't mix Apple and Crucial memory as you may run into problems.

I think i will have to take a look then in my machine and see what brand is already in there if it is not advisable to mix as i want to keep the 8GB that i already have and want to add an additional 8GB. I guess i will then know what brand to shop for.

You might, but as long as the specs match, it's probably okay. Admittedly, the last time I actually did this was my now long-gone B&W G3.

On the other hand, the OP might be better off in the long run replacing the 2 4gb parts with 2 8gb parts, leaving two slots free for future needs, rather than having 4 4's.Or he could put the two 8's in next to the 2 4's, that should work too.

Agreed.

Ive had good luck buying pulled apple ram one eBay. I upgraded my late 2015 iMac. I added an additional 8gb for a total of 16gb for about 50 bucks. Same exact ram that is in my mac now. Alot of people upgrade there macs to 32gb which for me is overkill and sell there stock ram cheap.

If matching ram identically is the most important thing to you, then I would replace what you are currently using, i.e. Find a make/model that works well in iMacs and buy 16 or 32gb of it, thereby replacing your current 8gb module. Then sell the old 8gb module.

According to Everymac.com: "By default, 8 GB is installed as two 4 GB memory modules (and two slots are unoccupied)." If this is true for your particular iMac and you want 16gb total, you'll have to either 1) get two more 4gb sticks and fill all four slots, or 2) get two 8gb sticks and sell off your existing 4gb sticks. #2 is better though because if you eventually want to max it out later, you can get two more 8gb sticks to total 32gb.

About getting different sticks per slot, our 2008 iMac 21" originally had 1gb. I added 1gb more of aftermarket ram. Later, I maxed it out with two second-hand 2gb sticks of different brands. I've also maxed out a 2004 iBook and a 2009 MacBook white with second-hand ram of different brands. I've also handed down ram from my 2012 MBP 15" to my daughters 2011 MBP 13, and it was a faster speed than what her MBP had. I may have just been lucky, but I've never had a problem with third party and/or mixed brand ram.
