If my mobo supports ddr400 i cant buy any ram rated higher than that?

You can buy anything higher and it still works, the only thing is that your mobo will set it to 400 FBS because thats the max it can support, lets say u got a 500 DDR mem, then you can OC better than 400DDR

yup, but it has to be ddr, and not ddr2 or anything else. even when the mobo supports 400, u can run any memory thats faster on there, but it will only run at 400 until u OC
