Hi! I have a Dell Inspiron XPS laptop, the one with 3.4GHz CPU. It's not the newer XPS M140/M170 or XPS GEN2.
So, it has the older PC3200 RAM. I am now interested in upgrading from 2x512MB PC3200 to 2GB. But I found that the PC4200 RAMs are much cheaper than the PC3200's. So, I want to know whether I can use the PC4200 RAM on PC3200 machine? I understand that they have different FSB. But I don't know whether it can be downward compatible.
Also, if I can use PC4200 RAM, then does it matter I use DDR or DDR2?
If there is any other issues I need to note, please do not hesitate to point it out for me. Thanks very much!
