Does a motherboard with socket 775 support Core 2 Duo CPUs?

I have a D102ggc2 motherboard with socket 775 and my neighbour has a Biostar socket 775 motherboard.

He has a Core 2 Duo processor with 2.93 GHz and I have a Pentium 4 with 3.06 GHz. I wanted to change my processor and I checked the Intel website – but for my motherboard, the only supported processors were Celeron, Pentium D and Pentium 4.

How come socket 775 supports Core 2 Duo?

If I upgraded my processor to a Core 2 Duo, would it cause any problems with my DDR2 RAM, motherboard or any other component of my PC?

Answer

Core 2 required a voltage regulator on the motherboard that was not needed for the Pentium D line of processors, all early 775 socket motherboards do not have this VR, which includes your Intel mobo, so no it will not work.
