With your original modules in place check the firmware level see if it needs an update. Follow this Apple TN: [http://support.apple.com/kb/HT1237|EFI and SMC firmware updates for Intel-based Macs]. Sadly, your MacBook also has a limit of how much RAM it can support, it can not exceed 2GB. The limit is based on the CPU's memory address lines. The '''Core 2 Duo''' CPU have more and can address more memory unlike your '''Core Duo''' CPU.
