HyperX PnP ram for new imac 27'' ?

That will work. DDR3 SODIMM @ 1600MHz is what you want to be looking for.

Don't forget the stock apple RAM is CL11, mixing RAM with different latencies (CL) can force the ram to run slower than the spec.

Like was mentioned before, the RAM you linked to is CL9, where as the Apple stock RAM is CL11. So if you are replacing all the RAM then that is no problem, but if you are just adding on to the stock, there is no reason to spend more on the faster CL9. It will function just fine either way, but to get the best performance you would want to swap the stock with new.

Forgot to mention that lol

Interesting... just installed 16GB HyperX PnP CL9 and left the stock RAM CL11 and everything runs at 1600mhz.

What is everyone's opinion, on which RAM is best, brand-wise. I have always used Crucial when upgrading RAM. I was thinking about possibly going with Kingston Hyper-X this time, but I ran it by someone and they told me to stay away from Kingston. Now, I know sometimes RAM won't work as good with one computer as it will another. So let's say, the Late-2012 27" iMac.

In my limited experience, you can't go wrong with the 2 C's. Crucial & Corsair. Never had a problem with either.

I ordered my ram from macsales.com. It was a little bit pricey but came highly recommended.

I really think I'm going to go ahead and go with the Kingston HyperX PnP RAM. I've heard nothing but good things about it in relation to Macs recently. Also, my friend that told me to stay away from Kingston, well, he's a complete moron and also says that "Mac's are useless and garbage", which shows that his opinions are crap, cancelling out his opinion on the Kingston HyperX RAM, lol. One thing is for sure though, the Crucial 16GB (2 x 8GB) RAM Kits are quite a bit cheaper than the HyperX PnP 16GB RAM Kits. The Crucial kits run $87, and the HyperX kits run $140. Which is almost double the price. Though I'm still not sure of it's performance versus long term reliability, or heat production. I do know that the Crucial RAM is CL11 (which apparently is slower, same as stock RAM), and is also 1.35V (or dual voltage RAM), where as the Kingston HyperX RAM is CL9, and is 1.5V RAM. So do you think the HyperX would run warmer or hotter than the Crucial? Also, if you know the HyperX RAM, you know that they have heat sinks on the outside. Though it needs to be said that with the 204-Pin HyperX RAM (ISODIMM), the heat sinks are basically metal decals, which I'm sure would help dissipate heat some, but I'm not sure.

$140 for 16GB of RAM? That's robbery. Sure it might be spec'd better (CL9), but I seriously doubt you would notice a difference between it and the Crucial. You could go with this kit, which is CL10, so right in between the Kingston and Crucial.
