I am thinking of getting a board with the H110 chipset but it only supports one dimm per channel, what does this mean exactly?

The board has 4 slots, so can I use 2 sticks of 8GB in dual channel? I am confused.

Channel A has 1 ea, DDR3 slot and 1 DDR4 slot, same with channel B - it's basically stressing to you that you can't run both DDR3 and DDR4 at the same time or in otherwords can't populate all the slots, they had hybrid mobos like this in the 775 socket when the change from DDR2 to DDR3 came and many ruined mobos and CPU trying to run both, trying to cram DDR3 or 2 into the opposite sockets, etc

yes its the H110M Combo-G:

so slots 1&2 support DDR3 only?
and slots 3&4 support DDR4 only?

will they work at dual channel? is there any drop in performance?

What does it mean at ONE DIMM per channel? what would be the difference if it supported 2 dimms per channel?

would 2 dimms per channel be faster?

Just exactly what it sounds like -- The two slots are mapped to two memory channels. You can use ONE DIMM (either a DDR3 OR a DDR4) in each channel. If the motherboard had 4 identical slots, then it would be two DIMMs per channel. But it doesn't, so you can only use either one or two DIMMs total with that motherboard.
