So I thought 4GB would be enough for me, I was wrong :p with 450MB on pageouts in 7 hours. I think its time for a little more ram, so im shopping around and need advice. I want a 8GB x 2 (16GB total) to set myself up for 32GB later on. So, what do you recommend? and what is this "Dual Channel" memory, and can I keep it with a ram upgrade. and I was thinking, could I put the stock 4Gb and combine it with 16Gb, for a total of 20GB? or would that not work? any help is greatly appreciated, would also like links if possible?

Thanks,
Jake
 
Jake, what Mac do you have?

The memory you need will be greatly dependent on the machine you have.

You can do that, but you'll pay $200 to add 16GB (2x8GB) that way. For $100 you can yank the stock 4GB and install 16GB (4x4GB). Or, for $50 you could add 8GB (2x4GB) for 12GB total. Either will likely give you plenty of breathing room for less per GB. The 8GB modules are still pricey, so I'd say wait til they drop in price before jumping to 32GB.

If you are based in the US (I know they ship internationally), go with OWC. My other option is kingston.
 
For my iMac, I went with "$50 to add 8GB (2x4GB) for 12GB total" - for my "average home user with NO gaming" usage and it works great. Actually, total of 8 GBs (using factory Apple 2x2 + 3rd party 2x2) would have worked great as well. But, RAM being so low cost price these days, I went 3rd party + 2x4s instead (to create 12 GB).

As seen below, Swap Outs = 0, and Swap Use is 0 as well…
