I use this motherboard:

And bought this RAM:
http://www.newegg.com/Product/Product.aspx?Item=N82E16820231310

It says 240-pin fits but it's not. What am I missing? Obviously I bought the wrong RAM, but how do I know which 240-pin is the right one? Thanks.

You bought DDR3 ram instead of DDR2 which your motherboard supports. DDR3 runs at a higher frequency, different timings, and different voltages. Send it back and buy some DDR2 800mhz ram because thats what your board supports.

your motherboard supports DDR2 (800 in particular) and you bought DDR3-1333. They have the same number of pins but they aren't compatible and they have a notch in different locations so you can't mix it.

You need to buy something like this - http://www.newegg.com/Product/Product.aspx?Item=N82E168...

you can get a 4GB single stick, but it is slightly more expensive than 2x2GB

as mightymaxio said, you bought ddr3 ram and a ddr2 mobo.
ddr2 and ddr3 are both 240 pin, but intentionally keyed/notched in different locations to physically prevent such mismatching.

Ahhh! Thank you all for the great replys. I see that DDR2 is a little more expensive but seems runs a little quicker. Anyways, thanks again! I hope I never make that mistake again :) .

Actually DDR2 doesnt run as quick its slower than DDR3. DDR2 has slower speeds but faster timings because of the clock per clock and voltage that DDR3 has.
