please dont be retarded and know that Gigabyte makes combo mobos that use both..I was making sure that one didnt..

And please realize that I have googled and many people are confused because unlike ddr, ddr2 and 3 both use 240 pins

There are several differences between DDR2 and DDR3. DDR2 is older than DDR3. DDR stands for double data rate. If you have a motherboard that supports DDR2, you cannot plug in DDR3. They are not backwards/forwards compatible. DDR3 is faster than DDR2 and it uses less energy, but the downside is that they are a bit pricey. So, if you have the money, I suggest DDR3, but if you're on a budget (like I am) there is nothing wrong with DDR2. It will get the job done just as well.

DDR2 and DDR3 use different voltages which means if they were plug-compatible, which they are NOT (the notch...), Very Bad Things would happen.

 

I understand that but its the voltage changeable?? So if in theory you could plug it in (the notch..) couldnt you adjust the voltage to match what ddr3 requires? just wondering?

 

I know some of you its your job..Im just learning from you and reading online so this is just general culture question!

You change the voltage in BIOS, but before you can get into the BIOS, the wrong voltage is already being sent to the RAM, which will fry it (or whatever). So you will never have a chance to even change the voltage.
