RAM Upgrade: Top or Bottom Slots? Please help.

[yustas]

Hello,

I went over memory installation instructions but it does not specify if it is important to put the same amount of RAM in the same memory bank. My new iMac has 2 GB in Bank 0 and 2 GB in Bank 1. If I leave everything as is and install 8 more GB of RAM, I will have the following configuration:

Bank 0 - 2 GB
Bank 1 - 2 GB
Bank 0 - 4 GB
Bank 1 - 4 GB

Is it important to match banks with the memory amount? If I do that, it will look like this:

Bank 0 - 2 GB
Bank 1 - 4 GB
Bank 0 - 2 GB
Bank 1 - 4 GB

Which way is correct?

Thanks.

The original memory will be in the top two slots. The additional memory will go in the bottom two slots.
Short end of memory to the right but check by looking in the slot. Firm pressure required to push the memory home.

Yes. The memory banks are horizontal.

I have the 2GB in the top slots and 4GB in the bottom. It was a hard push to snap the memory in but eventually it pops in and everything works...do it to it!
