keyed to fit into the RAM socket... so not only is it not a good idea to not mix RAM, the RAM module from the old machine will not fit.
Hi, I have a very stupid question.
I currently have a PC laptop and it is old. I am thinking to buy an Apple laptop possibly MacBook Pro, it comes with 1GB DDR2 PC2-5300 memory and it has one empty memory slot.
Can I take out the 1GB DDR 333 memory from my old PC laptop and plug it into my new MacBook Pro to make it 2GB memory? I just don't want to wast the memory in my old PC laptop.
In short, can I put two different speed RAMs on the same system? In this case, this will be my new MacBook Pro.
Thanks.
