I have a Dell Inspiron 1564 laptop (Intel core i3) that originally came with 2x2GB memory. I wanted to upgrade the memory, and I happen to have the Corsair Vengeance 2x4GB at 1600 mhz available.

I stalled the memory cards into my laptop, but in BIOS, it shows the memory speed is 1066 mhz. I tried to modify it to 1600 mhz but it won't let me (i.e., that area can not be modified).

Questions:
(1) How can I modify the memory speed from default 1066 mHz to 1600 mHz?

(2) If I can't modify it, how big of an impact will it have on my laptop performance?

Thanks a lot for your help!
 
Solution
You can't modify the settings. Dell simply doesn't provide the means to do so. Performance will not be affected other than running at the lower speed (which is the speed you were running anyway).
