pc4200 and pc5300

[cartex]

I have a new HP Pavillion DV9207us laptop. It has 2 sticks of 512mb DDR2 PC4200. I want to upgrade the laptop to 2GB by using 2 new sticks of 1GB DDR2 PC5300. Will this work ok?

should work fine, it most likely will just run at pc 4200 speeds.

jkresh is correct. It probably will run fine, but only PC2-4200 speed.
