Question about memory upgrade for Compaq laptop

I have a Compaq C301NR laptop, 1.73 GHz CPU. I want to upgrade the memory and I would like to purchase generic memory, at least some memory on eBay that isn't made by Compaq. My system supports PC-5300. Does anyone know if off-branded memory will work in my laptop, or do I need to buy the Compaq stuff?

Any brand of memory should work with your laptop, then again I know more about desktops then laptops. Here's a link for Crucials website for your PC's memory.
