computer ???

can pc2100 and pc2700 memory ram be run in a computer at the same time. I'm saying no, but there are others smarter than me here that I know will correct me if I'm wrong.

Yes it can. But if your processor requires 333Mhz or faster front side bus. It won't run at full speed (pc2100 is 266Mhz and pc2700 is 333Mhz) and it will only run at the speed of the slowest dim when different speeds are installed. If you have a 266Mhz or slower FSB then you won't have any issues running both at the same time. What processor do you have?

Also the slowest memory often needs to in the first slot for the machine to see the cards. And some motherboards it might not work.

 

And which end is the first slot varies from motherboard to motherboard.
