Just upgraded my 2012 Macbook Pro from 4Gb to 16Gb ram. The best upgrade you can do to this machine IMO! - It's like having a new laptop.

I'm using it for dev tasks, running db server, large spreadsheets etc. But I'm sure graphics apps would see a similar performance boost.

Maxing out RAM has always been the best investment of your computing dollar, (and usually one of the most expensive) -- I remember ordering my MacSE with four 1-megabyte chips insead of the standard four 250KB -- and the dual floppy-drive configuration allowed you to run the OS from one and write data to the other without having to constantly swap diskettes.

I'm really jealous. When I wanted to upgrade the RAM on my computer I discovered that I'd been misled by the salesman who sold it to me. The only way my RAM can be upgraded is by replacing the motherboard. I'm battling on for the moment but will need to get a better computer soon as this one really can't cope with my demands.

2x8Gb sticks were €149 (about $200) - Definitely worth it. I reckon it'll pay for itself in a couple of weeks in terms of my frustration at hanging apps and spinning beachballs!

edit: wasn't a productive comment

congrats sir. welcome to the world of 16gb

Has anyone had any (Mac) experience with going over the maximum Ram limit? For example, i have a mac mini - bought with 4gb which i straight away maxed out at the recomended limit of 8gb. I've often read online of people not paying much attention to the limit and going well over. I was wondering if i could go up to 16gb.

Well, if the apple knowledge base is to be believed, then the supposed max ram for this MacBook Pro is 8Gb - But I read a few other forums where people had upgraded to 16Gb (2x8) and had no problems. And it seems to work for me as well so far.

Perhaps Apple only want to talk about 'apple supported ram' which goes up to 8Gb, or maybe they're trying to encourage people to upgrade to a new '16Gb' macbook, who knows?

I don't know this for the Mac Pro, but I know a lot of computer manufacturers use low clock speed 1333 RAM to save money. Part of the performance upgrade you see may be due not only to the extra RAM but also due to faster modules (assuming you bought faster modules!)

Yeah, that's one thing I made sure of. I got 1600Mhz DDR3 ram (same spec as the ram that was originally in there) - Didn't want to get weird freezing issues.

Just because the computer "sees" the RAM and it boots doesn't necessarily mean that the computer can use it and map things to memory above the 8Gb.

Dave is quite right.

Do take a look at MS's chart of RAM limits on different OS's.... (Note that x86 = 32 bit)

On OSX Activity Monitor is a good way of seeing ram usage. Zero page outs is good - If this number is high it means there's a lot of swapping to disk going on;
