Just wrote an email to my friend discussing the RAM options on the newly released iMacs…I have decided to put it here since it might be useful to others who is getting Apple’s new iMacs. 🙂
Note: The information below may apply to the iMacs in New Zealand only, I am not sure whether the specs in other countries will be the same. The prices are from Student IT. This friend of mine is using the iMac for her design work.
Here is a few background information that you might want to know:
Q. Some RAM have ECC, what does it mean?
Q. Does my iMac use ECC or non-ECC RAMs?
A. Since ECC are quite expensive, the iMac only uses non-ECC ones. ECC ones are used mainly in things like Servers where availability is considered to be very very important.
Q. What do you mean by dual channel?
Q. What kind of RAM does my new iMac comes with?
A. Your new iMac comes with 1 stick of 1GB of RAM. There are two RAM slots in your iMac, and one of them is taken at the moment. Your mac will be using DDR2-667 RAMs.
Here are your RAM options:
1. Just do the plain upgrade from 1GB to 2GB, which adds an extra 1GB of RAM to your iMac.
Total RAM: 1GB(slot one) + 1GB(slot two) = 2GB
Pros: Cheap upgrade, make use of dual channel technology.
Cons: If you want to upgrade to 4GB of RAM later on, you have to take out the original RAMs and put two 2GB sticks into your iMac (remember you only have two slots).
2. Take out the 1GB of RAM in your new iMac and replace it with a 2GB stick.
Total RAM: 2GB(slot one) + 0GB(slot two) = 2GB
Pros: Cheap upgrade later on. If you want to upgrade to 4GB later, you only have to get one 2GB stick.
Cons: Won’t be using dual channel until you upgrade to 4GB of RAM. You can’t see the benefits unless you upgrade the RAM.
3. Take out the 1GB of RAM in your new iMac and put two 2GB of RAM into your iMac.
Total RAM: 2GB(slot one) + 2GB(slot two) = 4GB
Cost: 250 + 250 = 500NZD
Pros: Probably won’t need an upgrade for a very long time. No need to worry whether there is enough RAM for your application. (at least for a few years)
Cons: Need to pay a lot more than the previous two options.
Q. Wait a minute…it’s way cheaper when you buy the RAM from *** shop online, why don’t you…..?
A. I am doing this for FREE, I am not charging my friends for anything, so I won’t be dealing with any hardware issues @ all. If they want to buy the RAM from other places, thats fine with me, but I won’t be the one who is going to open their computer and putting them in.
My choice: I prefer the second option. Because you won’t be paying a lot more right now, but you are prepared for the future.
The END 🙂
Hope this will help you when you get your new iMac 😉
