Has a core 2 duo, so the OS must be 32 bit... https://discussions.apple.com/thread/4141844?tstart=0 ok so press & hold 6 & 4 after chime... Macs are odd, why not just boot th 64 bit by default???
Far too many wrong assumptions in this thread!
It's a design limitation of the Intel 945 chipset. Any computer with the same chipset is similarly afflicted. The iMac 5,1 would have shipped with 512MB which was plenty at the time. The 965 fixed the issue a year later in the aluminium iMacs.
The Core 2 Duo is 64-bit capable as is OS X on compatible hardware, including the old PowerPC G5. That said, Apple boot most pre-2009 Intel machines in EFI32 mode. Core 2 machines will run 64-bit Intel applications on OS X 10.5 and higher no problem even on the older hardware.

The Core 2 is 64-bit. As I've said above it's a chipset limitation. The 945 launched with the Core Solo/Duo which are 32bit CPUs. The Core 2 added 64-bit support. The memory controller for these CPUs machines is on the chipset, unlike the successor i-series which moved it onto the CPU die.
Yes you can look it up. MacTracker, Everymac (and even Wikipedia) should give you somewhere to start looking.
Hell ... thinking about it ... even the late Pentium 4s were 64-bit.

No. There was no other chipset option available. If you'd done the tiniest bit of research before keyboard warrioring out a reply (see post #6) you'd know that the Core 2 Duo Macs of that era (Sept 2006) all use a mobile platform. That's the CPU and chipset. There was only the 945 available. Intel didn't release a mobile chipset capable of addressing 8GB of RAM until the middle of 2008.
I'm not aware that Steve Jobs owned a time machine.
