240-pin DDR3 dimm is currently the fastest memory. it can support quad, triple, or dual channels or be installed as a single dimm. it has an offset notch father from the center than a ddr2 dimm

DDR3 uses lower voltage
No, you can't use same DIMM slots for DDR2 and DDR3 due to different position of the key and interface incapability.
2.66" 204-pin SO-DIMM contains DDR3 memory. The one notch on the module is offset from the center of the module.
DDR3 uses lower voltage
DIMM is a type of computer memory for your computer, and it supports certain types of channeling. DIMM 1, 2 3, and 4 supports some types of dual channelling.

Most likely DDR3 SDRAM. It is capable of triple-channelling, hence the three yellow label slots. :)
DDR3 memory provides a reduction in power consumption of 30% compared to DDR2_SDRAMmodules due to DDR3's 1.5 V supply voltage, compared to DDR2's 1.8 V or DDR's 2.5 V.
