whats the difference between sigle and double sided RAM ?

I just had to buy 256 MB of PC133 ram for my daughters computer and they gave me Single Sided what is better ?

Thanks

You're not slick. I can see that you're trying to start a single sided vs double-sided format war. I don't really know what the difference is myself, but I'm sure someone does.

I found this

What's the difference between single-sided and double-sided RAM?

Which one it better

Most of these issues has been dealt with recently in

"Why is the new RAM only half there"?

In short, memory modules on the newer single-sided chips are denser, enabling more capacity. What took 16 chips to make a 256M module, now takes eight chips.

However older motherboards may not recognize single sided memory as such and you may find you only get half the rated memory in your system.

So unless you have a new system or recent motherboard upgrade opt for double-sided, if you have a choice.

It is not confined to DDR RAM -- Rambus RDRAM also comes in single-sided memory versions.

The main way you tell the difference is that the double sided memory modules are (usually) 16M and the single sided ones are 32M.

Just do the math: divide the rated memory by the number of modules. The single sided one should = 32 and the double sided one, 16.

I am unaware of any performance benefits of similarly rated modules. If it's PC 133, it's PC 133 whether it's single sided or not.
