Hi guys,

I have just acquired my first iMac, albeit second hand. It's only has 4gb of Ram currently with 2 spare memory slots. I have just subscribed to Adobe cloud and downloaded Lightroom and Photoshop, I was thinking of adding an additional 8gb.

My question is do you think that's enough, I may be able to stretch to 16gb but would have to shuffle finances.
 
Memory from Apple is expensive an upgrade from crucial is just as good and a lot cheaper
 
I have been using 8gb Imac with icloud, LR and PS without problem for what seems like years. 8gb is enough.what you need more is big, big and fast external hd.
 
8 GB is a bare minimum, and to be fair 16GB doesn't cost 2x as much so just get that in place.

Even better get an SSD for system drive if it is not already. Then even if it caches heavily you'll hardly feel a thing.
 
Adding an additional 8GB as you say, to give you a total of 12GB, will be more than enough for most uses.

If it's an oldish machine, I'd bet the processor is going to hold you back in Lightroom before then RAM does. Photoshop will use everything you let it use, but whether you run into any bottlenecks, depends on how heavy a user you are.
 
I'm with James on this one, 12 GB total should be plenty. However as daugirdas says, 16GB is not that much more, I would get that and have 20GB in total...
 
I have been running Adobe CC (Photoshop and LR) on an i5 with 8Gb of RAM and never once found it slow.
 
I've tried 4gb, 8gb & 12gb.
I found very little improvement going from 8 to 12.This was running PS & LR together but it was a reasonably old mac.
I don't normally touch the darkside

Don't forget it would also depend on the RAW files you use. In my experience there is very substantial difference in resources needed going from 10MP (40D / 1DIII) to 16MP (1DS II) and then to 5DIII. 8 vs 12 is a relatively minor jump...
 
Hi guys,

4GB of RAM + the addition 8GB you're thinking of = 12GB RAM. Sounds good enough to me. But everyone have different ways of doing their work, so you would have to figure out if adding another 8GB is enough for your needs or if you want more like 16GB.

Put it this way:

Think of RAM as a desk. Are you the kind of person who would open an image file, edit it, save it, then close it before opening another file? That would be a bit like you place some papers on your desk, work on it, then you put them away before placing different papers on your desk. So even thought your desk is big enough for you to work on few pages at one time, great. But some of us, could be the kind of people who open, edit, save, open another, edit, save, open yet another, didn't seem to bother closing the iamge files we've done editing with. Bit like place papers on your desk, work on them, then actually shove them to the side, and place more papers on the desk, the more papers you place on it, without actually putting the earlier ones away, sooner or later your desk will be covered up with hardly any room.

Adding an extra 8GB would be a bit like deciding to use the dinning table instead of your desk, more room for you to place all the papers all over it.

If you were to consider yourself being more likely to open Lightroom, open a dozen image files in Lightroom, then open Photoshop, open a dozen files, (not bothered to close Lightroom when opening Photoshop), and maybe even open iTunes and play music, leave your browser open, it would be like you're actually placing more and more stuff on the table, and if you think the only place big enough to work on is the floor, then it would be a bit like the need to add 16GB.

So woudl you consider yourself likely to have a couple of programs open, maybe only a very few files open, and you would actually close any when you're done with them, or would you consider yourself to want so many programs open, and more than a dozen files open? Do you feel the need to use the dinning table or the floor? So hope this gives you some idea to help you feel if 8GB is enough for your nees or if you think you need more, and go for 16GB.

Hope it gives you a thoughts on how much more RAM to go for.

It's also worth checking what the max memory limit is your iMac will take - I think if you pop on Crucial's web site and choose your model, it will tell you the max it'll run.
 
As several people have mentioned, Crucial are a good place to go for Mac memory. I've just updated a 2009 iMac for a family member and used Crucial with no issues (been using them for years for Windows systems)
 
Hi guys,

Thanks for all the reply's.

I'm am looking to order from crucial, maxim the machine takes is 32gb. Think I'm going to order 16gb.

I'm the open one file do the editing, save then close and then go to the next sort of person. But while I have the spare cash might as well go for the higher amount. Having 20gb should be enough.
