Basically the performance loss by not using matched pairs is outweighed by you having 3 gb.
According to crucial website, the iMac does not support dual-channel memory so you do not need to install identical pairs for optimal performance. The mini, on the other hand, does support dual-channel memory, as with the macbook.
