I have a Dell Latitude D820 laptop, which is now around 3 years old. The DDR2 memory speed for that laptop is 667 MHz. I have two 1 GByte modules in there, which I would like to replace with two 2 GByte modules, to upgrade my total memory to 4 GB.
When I look at the Dick Smith website, I can see a 2 GByte DDR2 module, such as this one. However, that is rated at 800 MHz. Apparently, they are not selling 667 MHz memory modules anymore.
Is there a problem with using 800 MHz modules in a laptop that only runs them at 667 MHz?
Thank you for your help...
