4 gb = normal user/grandma checking emailIs there anything you can do with 32Gb RAM and you can not do with 16GB RAM?
Adding 16GB to bring the system to 24 GB is a rather reasonable way to go for people who need more than 8GB but likely don't need more than 24GB. It still leaves the option open to replace the original 8GB if it turns out the do need 32GB and doesn't waste money.I went for 32 gb but after thinking about it I came to the conclusion that I wasted money. i could have just got 16 gb of ram and kept the 8 that i had for a total of 24 gb. that would have been more then fine.
I'm actually glad there aren't many 4GB systems sold anymore. I've seen normal users open too many tabs and slow their system down.4 gb = normal user/grandma checking email
8gb = power user/watching lots of video/gaming
16gb = super power user/ deceloper with 200 tabs and 3 development programs running
24gb = running multiple virtual operating systems
32gb = extreme cases
If you are buying it, buy DDR3-1600. If you have it already, don't worry about it as you won't notice any difference unless you are benchmarking.What kind of RAM should I put? 1333 Hz. 1600Hz ... 1300Hz ...
I concur with you mate. On my 21.5" Haswell, it's only got 16GB of RAM and once I open up a VM to use AutoCAD, then it starts paging. I assigned 4GB to the VM. It also doesn't help that I have Photoshop CS6 open half the time. If only VMware or Photoshop was running, it'd be fine. But since I use both half the time, it's not fine at all.I bought 16GB of RAM for my Mac Pro 5,1. I thought it would be enough, but I get page outs all the time (2-4GB per day). And my free memory is usually very low. So I wish I had bought 24GB or 32GB instead.
I don't get how 16GB is not enough, as I don't do anything out of the ordinary. The software I usually have open is Safari, Mail, Contacts, Notes, Calendar, iTunes, Mark/Space Notebook, uTorrent, Vuze, Skype, Dragon Dictate and one Win XP virtual machine in Fusion with 1.5GB assigned. Normal stuff.
Beats me, but I know that apps take forever to load (takes about a minute just to open up Safari) after a purge on an RPM drive.Why is that exactly and it doesn't have an affect if there's an SSD instead of a hard disk?
Interesting. I guess the lesson is to be sure one has an enough RAM for his or her needs.Beats me, but I know that apps take forever to load (takes about a minute just to open up Safari) after a purge on an RPM drive.
Paging is like using hard drive space as a temporary form of memory. But note that accessing it from an RPM drive is a hundred thousand times slower than accessing from RAM, and accessing it from SSD is a thousand times slower than accessing from RAM.
Quite right.Interesting. I guess the lesson is to be sure one has an enough RAM for his or her needs.
I have 8Gb of RAM on my new iMac (spec bellow), and I had Google Chrome open with 2 tabs, iMovie open with a 1 hour 40 minutes video, Apple store, and iTunes, and I had no page outs, just 13Mb compressed. Very happy as that is more that I would normally ever doI concur with you mate. On my 21.5" Haswell, it's only got 16GB of RAM and once I open up a VM to use AutoCAD, then it starts paging.

The Haswell 27" in my basement server room, that's got 32GB of RAM and by far, that's quite fine so far, although with all sorts of things running, I last on just 2GB of RAM free on that machine.
But at least on the 21.5", it's okay paging because I went for a 256GB SSD, although slower, but still it's not as slow as paging with a 5400rpm drive.
