Different types of SD Ram

Is there different types of SD Ram? I ordered 256MB of SD Ram but when I received it it only had one groove in the middle and not one in the middle and one towards one end. What SD Ram is this and which one do I need with 2 grooves in it? Thanks.

Thanks feb I know the memory stick is wrong but can I confidently go back to them and say they sent me the wrong stick. Does SD Ram have 2 grooves and DDR Ram only have 1? It looks like they sent me DDR Ram but it is not compatible with the motherboard.

Thanks dan11 so they have sent me DDR ram when I ordered SD Ram.

Thanks both for your help. I would have got a bargain if it was compatable!!
