Short answer: yes it will work.
The DDR3 memory on the graphics card is mounted in the GPU's PCB. Power regulation and clock signals for that memory is regulated by the GPU.
The DDR2 memory on the motherboard is a completely separate situation with the voltage and clock signal being regulated on the motherboard. The two memory banks have little, if anything to do with each other.
A PCIe GPU will work in any PCIe motherboard slot.
DDR3
Yes. i use a graphics card with gddr3 while i have ddr2 myself. also, ddr3 is the latest for computers and the new videocards have gddr5.

Unfortunately, no. DDR RAM will not work in a DDR2 motherboard, and DDR2 RAM will not work on a DDR3 motherboard. There are a few motherboards that have slots for both DDR and DDR2, so it is conceivable that there could be motherboards with slots for both DDR2 and DDR3.
well ofciurse it will lol
Gt 240 ddr3
GPU memory is independent of the motherboard that runs its own memory. You can have only one type of memory on a motherboard, ie. DDR3, and have a graphics card with built in DDR5 memory. Short answer is yes, they are independent of each other.
No, it's a type of RAM
No, but I think you've got a few terms confused. DDR2 "slots" are for the main system memory. A "DDR3 graphic card' is a graphic card that uses DDR3 memory. A PCI-E DDR3 Graphics card should work fine in a PCI-E slot, or a AGP DDR3 Graphics card should work fine in a AGP slot (4x or 8x, dont try to use a 4x or above AGP card in an older x1 or x2 slot).
If you are using DDR2 RAM, then yes your video card should work. Provided you have suitable power going to the GPU.
GDDR3 is referring to the type of VRAM the graphics card has. If the graphics card is a pci-express one, then it can be installed into the motherboard if it has a pci-express slot available. DDR3 is referring to the type of Memory/RAM
DDR2 and DDR3 are different types of RAM. Interested that you posted in graphics cards as well. Heres why: For system memory, RAM that you can buy and replace on your motherboard, there isn't any performance difference. ddr3 is NOT faster at all significantly. Its a different type, you simply need to get the same type for compatibility. On laptops, ddr3 gives better battery life but not very significantly. For graphics cards, this is called vRAM and the types are usually called gddr2 and gddr3. In this case, gddr3 is MUCH faster. A single model of card will be produced in both types, which is confusing, and for example an 8600 gddr3 is probably faster than a 9600 gddr2.
