Memory upgrade for Compaq Presario P906US

[Dilbert]

I have a Compaq Presario P906US laptop with only 128 MB of RAM.  I would like to give this laptop a little more life by adding memory.  Can I add memory by adding to or replacing the current memory? Will additional memory boost my performance? What are my options? Thanks.

You can increase the memory to 1 GB with so-dimm DDR 266 PC2100
This greatly increases the performance of your pc

There are two sockets. One contains the original 256 MB module.  Must I put a matching 256 MB module in the other or can I add a 512 MB one? Or can I remove the 256 MB original and replace it with either a 512 or 1024?

HI,

Each slot accepts up to 512 MB. So you can do what you want, for the moment or you do not exceed this limit
