Re: Compaq Presario 5410us - memory

Hi, David:

Below is the product specs link to your model PC.

The maximum memory it can take is 2 x 256MB memory modules for a maximum of 512 MB.

Windows XP 32 bit can address up to 4 GB memory, but the hardware in the PC also has to support that as well.

Unfortunately, yours does not.
