I have laptop with 2GB RAM,when I use cpu-z it shows memory frequency 798.1 mhz but the speed mentioned in laptop manual is 1066 mhz.When I searched internet using my memory model some sites mentioned laptop ram speed 1600 mhz.Actually I want to upgrade from 2GB to 4GB.How to identify my laptops maximum supported ram frequency.

post the screenshot of cpu-z showing ram details.

yeah cpu-z info is requires to answer this.

Your RAM is indeed 1600MHz (800 * 2, because Double Data Rate[DDR]). From your first post, I guess you are replacing the existing RAM module with a new one. If your laptop has two slots prefer keeping the existing RAM module with the new one. Just make sure that the latencies and frequency are same in that case.

can't see the attachments as this function is broken here(sometimes it works for some but mostly it doesn't).use imgur & also check your laptop ram voltage as the standard laptop ram will not work in a laptop which requires low voltage ram.
