I don't see why no one in this forum intends to add 2 x 8GB chips and keep using the 2 x 4GB chips that come with the iMac. Waste not want not... is there a problem with running 24 GB?

There is no performance hit for running 24GB of RAM if the RAM is installed properly. Ivy Bridge is dual channel so make sure you have 12GB installed on each channel.
That's because memory sticks come in 12GB size?!? They usually only come in 2, 4, 8, 16 GB sizes at the moment. Tell me how you can get a 12 GB module? :-D
Just make sure that both the sticks that form a dual pair are the same size and preferably from the same manufacturer and you'll be fine
FYI the 27" iMac has 4 RAM slots for 2 channels.
I know...not sure what your point is?
Well it seemed like you didn't. I mentioned 12GB on each channel which means 12GB in 2 RAM slots. The math isn't hard after that

No math seems to be hard for you: there are no 6 nor 12 nor 3 GB sticks out there. How could you put a 6 GB stick into one slot?

I'm honestly unsure on how this works. So is it better to have 8 and 4 in one channel and 8 and 4 in the other. Or 8 and 8 and 4 and 4 beside each other. Thoughts memory Gurus?
He's talking about an 8gig and a 4 gig in one channel to make up the 12 he's referring to. My question is that the way you should do it. Or have same memory sizes to match the one going into the same channel.
8 + 4 in each channel will give you dual channel. 8 + 8 in one and 4 + 4 in another will give you async dual channel which is a very small performance loss. Honestly it doesn't matter but if you want to be 100% sure you don't lose out on any performance just put 8 + 4 in each channel. I don't know the DIMM assignments for the new iMac but it is not hard to figure out once you get it (you have 50% chance of getting it right lol).
probably less than 50%, as you have 4 DIMMs and 4 slots, with 2 types of DIMMs, but as I only got 4 hours of sleep waiting up to order my iMac, I'm not doing the probability in my head right now-.-"(you have 50% chance of getting it right lol).

I came to ask this precise question. The consensus seems to be that, if you buy a 16GB kit (8x2) and put a stick in each empty slot, you'll be in sync and problem free. Right?
