Upgrading DDR2 SDRAM for laptop

3 posts · originally from https://geek.digit.in/community/threads/upgrading-ddr2-sdram-for-laptop.79440/

I have a laptop Dell Inspiron 6400 with 512 MB DDR2 SDRAM

I do not know the speed of the RAM. How to find out?

And also I would like to add an additional 1GB DDR2 SDRAM 667Mhz. Suppose if I find the 512 MB to be 533Mhz, is it still advisable to go for a 667Mhz additional RAM? Will they work together without any issues?

Yup they ll work. Check out the memory frequency in ur bios or use cpu z.

I find my laptop's RAM to be 533Mhz.

My laptop's processor is Intel(R) Core(TM) Duo Processor T2300.

Will I be able to install a 667Mhz RAM in the second slot that is available?
