More Memory = Faster Mac!
All iMac Intel Core Duo models have two user-accessible memory slots that support up to 2GB (2048MB) maximum. Apple recommends that memory be installed in matched-size pairs to maximize performance. With a matched pair installed, Apple notes that both memory banks can be accessed at the same time which will allow a maximum memory throughput of up to 10.7GBps.
