Extra memory for a C502US notebook

The documentation that comes with this, even on line, is laughable.

1) It has one 512MB module. Can I add a 256MB for a total of 768MB, or must
I add a 512MB?
2) Will any DDR2 work, or is there something special required?

Thanks.

If it takes DDR2, there is no such thing as a magical Compaq DDR2 module. All
the major computer manufacturers and white box builders of systems use the same
commodity memory nowadays. When adding memory, make sure that the speed of the
new memory is the same as or faster than the existing memory.

It is probable that 256MB would work, but why not simply go for 512MB and
eliminate the risk. And give yourself a treat... Ben Myers

You can get another 512 for $44. Why do less?

This memory is 4200. I am pretty sure mine is 5300. I realize you can mix
speed, but then it all slows down to the slowest.

Am I wrong about this, or is 4200 the fastest the C502 can profitably use?

You can try the 4200, if you have it already. You're way better off matching
the speed of a new SODIMM to the speed of the one in there now... Ben Myers

I've not known Crucial to make errors. If they say 4200, it likely is 4200.
