Can someone explain how memory works

[Hayabusa Rider]

I have a Inspiron laptop (8500)

I accidently ordered PC2700 for it, but I found out too late it takes 2100.

Now if it is just higher specs wouldn't it work, or is it more than this so that memory doesn't work at different bus speeds?

edit:great now the people that saw my old post thinks im retarded. anyways i think it should underclock itself to 2100. not sure because its a lappy.

As long as you got notebook memory and not desktop memory it should work. I've got no experience with the lappies though.

just stick it in, and run cpuz and see what the timings and speed is. it should just underclock to pc2100.

The memory won't "underclock"

Memory clock speed is determined by the motherboard, not the memory. Being PC2700 means that the memory can run UP TO 166MHz, where as PC2100 is specced for 133MHz. Running 166MHz memory at 133MHz is no problem at all.
