Re: Optimum configuration of RAM memory upgrade
I know that there have been variations of my question, but they do not precisely answer it. I have an iMac i5 27" (late 2009). It came with 2 x 2GB and the sticks occupied 2 horizontal slots. I have now purchased 2 x 4GB Crucial sticks and want to ensure that the upgrade is optimised. My current attempt is as follows:
12 GB Installed
2GB 2GB
4GB 4GB
The diagnostics say all OK.
However, Crucial are recommending :-
BANK 0/DIMM 0-4GB
BANK 0/DIMM 0-4GB
BANK 1/DIMM 0-2GB
BANK 1/DIMM 1-2GB
I do not know which slot relates to which Bank, but they do seem to be suggesting that the 2 x 4GB should be on top of one another, not side by side, which is how the Mac original memory arrived.
Can anyone help me to sort this once and for all. Knowing which Bank is 0 and which 1, would be a good start, and how significant is it that I have the configuration that I have. Am I adversely affecting the iMacs performance? Is it recommended that I change the configuration and if so, what to?
