See the support list at http://www.intel.com/products/notebook/chipsets/945GM/945GM-overview.htm
Also be aware that the BIOS is an issue here. You have to ask it's maker.
I have an Acer Notebook called Aspire 5572ANWXMi of 5570 Series and it is assembled with a motherboard which has a Core Duo Processor (1.73Ghz, 533MHz) on socket 479 mpga (shown by cpu-z), an Intel GMA950 integrated graphic. Its chipset is 945GM. The current CPU is for Socket M so will socket M's Core 2 Duo CPUs be compatible with my Notebook?
