You can mix and match sticks of ddr2 but they will need to be the same speeds aka 800mhz,
The way you would do it is like this.
Slot one (far left) 2gbstick second slot next to the first one 1gb stick and then the 2gb stick and the 1gb on the far right
1. 2/1/2/1 that should how it looks like
2. Some boards might be ok to have mix speeds, I remembered my mums board had 2sticks of 800mhz and 2 667mhz and it was ok about it but, I think you have to keep them in the same slot config as above
The configuration of the motherboard's memory channels can be different. Either read the motherboard's manual that should be online somewhere or often it is apparent the setup of the channels through the colors of the DIMM slots. The idea is to keep the 2 2GB sticks in the same channel and the 2 1GB sticks in the other.
The memory will be run at the same speed, regardless if they are the same speed. The higher speed sticks will be dropped to the lower stick's speeds. You can go to your BIOS and mess around with speeds, just keep in mind all sticks are run at the same voltage and same speeds so mix and matching can make things hard to find a good compromise of settings.
