Can I use these 2 memory sticks together?

Upgraded my sister's laptop memory and now I have her old 2gb stick (the clean one) just laying around, I was wondering if I could use the two sticks from the pictures in another laptop without having trouble.

Just try it,it won't really harm something. If it doesn't work is that something you kinda can expect since speed and timings seem to be quite different. Maybe with abit of luck will the bios smooth things out.

Thanks for your answer. I'll try that and if it doesn't work I guess I'll just stick to having only 2 gigs for now.
