This LED display unit simply fits onto a pin configuration on top of the XPERT memory stick. Obviously you see that the display extends over one side of the memory stick. The display is configured so that you can move it to extend over either edge of the memory stick. Of course on most motherboards that use a 2x2 DIMM configuration, you will only be able to install two display units, not that you would need more anyway. The height of the display unit should ensure that you can still install four sticks of memory in just about any motherboard given the proper headroom.
