PC 2100 and PC 2700 memory ram

Is it possible to have PC2100 and Pc 2700 ram in the same motherboard? For example, I have a stick of 512 mb pc2700 on my computer. Then can i add some pc2100 memory sticks that i have in my older computer to my newer computer?

 

You can do it but they will run at the slower speed.

 

so do u mean my 512 mb pc2700 will run at same speed as the pc2100's ?

 

That's correct. Assuming of course they're compatible. It's best to stick to the same make. Most combinations work but not all so watch out.

 

I checked the specifications for my motherboard and it said that it does support pc2100. But if i try putting the pc2700 and pc2100 in my motherboard, and if it doesn't work, will it damage anything?

 

It shouldn't. If there is a compatability problem it may not boot.
