Most motherboards will allow you to mix memory sizes, as long as you keep the corresponding DIMMs in each memory channel the same size. For example if you have a motherboard with a two-channel memory controller, you could have two 4GB DIMMs and 2GB DIMMs, but not 1 of one type and 3 of the other.

But it does vary by motherboard, so you really need to consult your manual.

Yes, but you shouldn't expect them to work flawlessly if they don't have the same specs (other than the size). What are the part numbers of your kits?

Is this for a laptop or a desktop? Don't you have a manufacturer/part number? 1066 MHz and PC2-8500 are the same speed.

It should work as long as the laptop supports 4 GB modules.

Just make sure that it will support modules of a different size.
