Hi:

Below is the link to the service manual for your notebook.

The memory upgrade info can be found in chapter 1 on page 1.

2 x 2 GB of DDR2-6400 memory is the max.

I read the specifications it is having core2 duo processor but ny processor is of pentium and the model is CQ 40 PC notebook but mine is CQ40-601TU notebook not this so I am having doubt this will support or not. So please solve out this problem

Below is the link to the parts list for your notebook.

According to the parts list, it has a Pentium T4400 processor, correct?

While the manual does not list your processor, it lists the T4200, which is in the same family and also supports 2 x 2 GB of memory, as do all of them.

Ok thanks a lot

You're very welcome.

All you would need to do is to replace the 1 GB chip with a 2 GB chip and also the memory will run in the higher performing dual channel mode.

Right now the memory is only running in single channel mode with 3 GB installed.
