Ask questions about memory Addition

For more information, see Linux general technology-Linux technology and application. Want to add memory to the computer, CPU: T4300 (Front-End bus 800) motherboard Intel TCH9M (Front-End bus 800), original memory ddr21G (Front-End bus 667, A little loss ), it is a dilemma to add 2g. if you add 1 gddr2667 or 800, it is a waste of CPU resources. If you replace all the resources with DDR31066 (I don't know whether DDR3 800 is available now), you have to discard the original DDR2, is it best to add an IGDDR2800? Thank you! 0 wmjh (1
