    I got a laptop that came with PC4200 RAM. I read that I can buy PC5300 RAM and the laptop will still run it but at a slower speed? I'm not going to mix the RAM. Only have 2 slots so I will put in both 5300.

    it will run as fast as it can up to the rams max speeds. whether it is your motherboard limiting it or another ram module limiting it. if your motherboard supports the full speed and you remove the other ram, it will run at full speed.

    You read correct.

    All DDR2 sodimms are backwards compatible.

    Actually running higher speed memory in a system which runs it at a slower speed, is better than using memory which is designed to work at the frequency of the memory slots, as the faster memory cards are "underclocked" so to say, and generate less heat.

    I did this with my E1505, I replaced the 533Mhz memory with 667Mhz memory, which runs at 533Mhz. I8KFANGUI, reads lower memory temps with these modules, as they are not running at their full frequency,

    Memoryt bandwidth is not skewed by doing this, as from my SANDRA results, the bandwidth difference before and after the memory change was negligable.
