RAM backward compatiability

What will happen if i try to use my 256 DDR RAM of speed 266 with a DDR RAM of different RAM different speed ..say 256/512 MB DDR speed=677 or 256/512 MB DDR speed=533 or any other speed. I have head about RAM's backward compatiability , does it mean that if i try to run my RAM of speed 266 with any RAM of greater speed both will run at the lowest speed i.e 266 ??
Also if i want to use the 256 MB speed 266 with a RAM of greater speed,is there any limit the higher RAM should have, say it should not be above 677 or something like that?

Yeah both will run at the least level of speed. Most of the times problems occur while doing so. But I don't know of a limit other than the one set by your motherboard.
