It's not clear from your question whether you mean that the memory slots are different from what you are used to (often black) or different from each other. If you have four slots for memory and two are one color and two are another color (often alternating) I would guess that is because many MB memory configurations must have matched size and/or speeds within any given "bank" of memory but often you can mix sizes and even sometimes speeds in each separate bank. I.E. in the two red slots you may be able two put two 2 Gb memory modules and in the other two slots, perhaps black or green, you could install two 1 Gb modules. This would work fine but if you installed one 1 Gb and one 2 Gb in the red slots and the same in the other bank it would not work at all.

The ASUS P5K motherboard has 4 DIMM slots, alternating in color black and yellow. It supports up to 8GB of RAM and does so in dual channel. This means you need two identical RAM modules in the same color. For example, if you wanted to add 6GB of RAM in which you had 2x 2GB and 2x 1GB, you would add both 2GB modules to one color (ex. Yellow), and then both 1GB modules to the other color. Both 2GB modules should be exactly the same, and both 1GB modules should be exactly the same, but all 4 modules don't need to be the same.

It doesn't matter which group you put in which color, so long as they match. If you put a 2GB module in each yellow and black, then a 1GB module in each yellow and black, you're not running in dual channel and therefore running inefficiently, if at all.
The specifications page has more details about the exact type of RAM you can add.

The 3x white expansion slots are only PCI, the black is a PCIe x1, and the blue is PCIe x16 but can function the same as the black. The blue slot is the only one that supports their Cross Fire technology, so that's where you want your graphics card.
