The same type of RAM with higher speed capabilities can be used on motherboard which supports that particular memory type, but it will work to the rated speed supported by the motherboard or at the speed of the slowest memory on the memory bus.

PC5300 is more correctly "PC2-5300" and can work in a system that has "PC2-3200" RAM. As Neeraj stated, if mixed, they will operate at the speed of the slowest module. "PC-3200" RAM, however, is not compatible. PC-3200 is DDR SDRAM, having 184 pins. PC2-3200, and PC2-5300 are DDR2 SDRAM, having 240 pins. DDR and DDR2 modules are the same length, but the pins on DDR2 are smaller and the keying notch is in a slightly different position. -Jamal
No, it's not. PC5300 is DDR2 and PC3200 is DDR. they are not inter-operable. If your MB currently has PC3200, upgrade/replace with PC3200, if you wish to use PC5300, you probably need a new MB.

As long as your motherboard supports PC3200, yes. Find out what motherboard you have; if you self-sourced it, it'll be on the box so have a browse through the manual and it'll say what memory speeds it supports. If its a pre-built machine, e.g. Dell, HP, etc. Have a look around for the model number on their websites.
