What is the memory capacity of this computer? Let's say, I need a minimum of 16 gigs of memory. Could I install two 8 gig memory sticks?

Not that I am saying that the other people who answered are wrong, but I have the mid 2011 model iMac, which came with 4gb of RAM, and it says on the box and on the Apple website that it is not upgradeable. On mine, I was able to take off the back cover and there were two empty RAM slots. So I replaced the two 2gb RAM sticks with 4gb, and added 2 more 4gb of RAM. I now have 16gb of RAM in my computer and it works like a champ...performance and speed wise.

According to what I found out The 21.5 inch iMac does not have the ability to change out the RAM if you want to upgrade. But do not take my word for it. Do some research as things change so rapidly with computers, as you know new os'es are coming out faster each year. New intel chips too with imacs etc. It wont be a bad idea to talk to apple about this question as well. You can log on to their apple store website and launch a chat with a rep and ask this same question they might guide you to the best imac for you that may be able to upgrade or you never know this imac now may be able to upgrade as I said changes happen quickly to many of these devices that its hard to keep up. Speaking to a representative at apple will help you as well. I hope this has been at least some guidance for you. Good Luck with your search and your purchase.

You need to purchase this model pre configured with the RAM as the 21.5" iMac doesn't have a way for the user to change the Ram themselves (you have to have a service center do it). I recommend getting the 27" model which has an access panel that allows you to change RAM. Plus the screen is bigger! In hindsight, I wish I had spent the little extra for the 27" iMac to be able to have the options to expand RAM and other things in the future.

I believe there are only two slots for ram memory sticks and both are being used by the existing 2 gig of ram each. To get it up to 8 gigs you may need to remove both memory sticks and install 2 new ones of 4 gig each. Basically you are throwing away the existing ram to upgrade to full 8 gigs. As for me, since I only use it as a multimedia server for my bedroom the 4 gigs is very adequate. Good luck.

You can use up to 2 GB per slot, so the max would be 8 GB (up to PC2-6400 speed), I have not tried 4 GB memory in one slot, it may work, but isn't officially supported.

This model can support up to 16GB. There are two RAM slots, one is occupied by 1x8GB leaving a second one open for upgrade.

Since it is a 64 bit system, you can upgrade the ram up to 32gigs but the most available in one RAM card is 8 gigs so 16 gigs is pretty much the max.

Check the specifications for your PC - especially the capacity of RAM for that specific motherboard. I suspect it will be 4GB max, much faster than what you have now. If there are four bays, you can try and add the two stick and see what the motherboard will accept at boot-up. Before ordering, be sure your memory sticks match.

Hello, We are the manufacturer of this computer and would be glad to assist with your questions! The computer does not have the ability to add a second hard drive to it due to the form factor being so tight. The maximum RAM that can be installed is 32GB on 4x 8GB sticks. There are slots currently available, however any expansion slots such as a video card will require a low profile bracket.

As far as you can with two slots of laptop RAM. I was able to put 8GB in there and it improved performance a lot.

It will depend on how many slots your machine has available for RAM. Look in your machine to see if you have an empty slot. If you do, then you can just put more RAM in the empty slot. If all of the slots are taken, you will want to replace one of the smaller sticks of RAM with a larger one.

Alejandro My unit came with DDR3. There is room for a total of 16GB with two identical 8GB memory chips. My unit came with an 8 plus a 4, meaning that in order to fill both of the memory slots to capacity, the second chip would have to be totally removed and replaced with another 8GB DDR3.

I was looking at this model at Microcenter today and I assume it has the same specs. It has 4 memory slots and 2 are taken with 2 4gb sticks, so you should be able to add two more to give a total of 16gb.

You can get two 4 GB sticks of memory instead. Here is the Amazon link. Good luck. Corsair XMS3 8GB (2x4GB) DDR3 1600 MHz (PC3 12800) Desktop Memory (CMX8GX3M2A1600C9)Willis (Bill) Van Gorder

You can use 2 sticks of 8GB each for a total of 16 GB. If you are using Linux instead of Windows you may need to download new chipset drivers.

I ordered this product, and it is for one 1Gb stick. If your computer has 2GB maximum memory capacity, you will need to order two to fill that.

Yes, it should be fine with an 8GB stick and a 4GB stick. Though you'd get slightly more performance out of 2 x 8GB sticks.

Shouldn't be a problem, just purchase another 8gb stick. Also agree with the other answer an ssd is a much better way to upgrade this notebook. I talk about this in my review. About the other answer though, he/she indicates two ram slots are in use. At least in mine it came with one 8gb stick instead of two 4gb sticks.
