How can you spot the difference between GDDR2 and GDDR3?

I just bought a computer and I'm not sure if my graphic card (nVidia 8600GT) has GDDR2 or GDDR3. Is there a way to see/read which type has it? Some program, (like RivaTuner, SiSoft Sandra, 3DMark ...), the card's BIOS (how do I enter the BIOS?), anything else ....
