On the LGA1366 and LGA1155 CPUs the memory controller resides on the CPU die itself.
LGA1366 CPUs have three memory channels.
LGA1155 CPUs have two memory channels.
There aren't enough pins on the LGA1155 CPUs to add an extra memory channel. Also an extra memory channel is of no benefit because the LGA1155 CPUs are not memory bandwidth constrained.
If you're trying to fill all four memory slots of an LGA1155 motherboard you should be looking a two dual channel kits or a single quad channel kit with a 1.5 Volt or lower operating voltage.
