Can I use 3000 Mhz ddr4 Ram on H110 with the rated 3000Mhz frequency?
My another question is "In dual channel mode does OS stores the same data in both the channels?"
For example if I use two rams on H110. Will OS store same data in both sticks to increase bandwidth?
And last one "what does single stick per channel mean in H110 specification, given on Intel ark? "

1. No. The H110 board is limited to 2133Mhz in its support. 3000Mhz will run, but not at 3000Mhz

2. I don't understand the meaning of your question. With a dual channel system, one channel is always available for loading, refreshing, and housekeeping while the other channel is being read. The channels are read alternately, one being read into the buss while the other is being prepared for use, or being written to. What exactly happens depends how the memory controller and it's firmware are programmed and configured. With single channel operation there is always something "waiting in line" while the memory is busy. This limits what operations can be performed, and those generating a "write" instruction have to wait their turn...

3. Each of the four channels can handle one memory stick. Some motherboards allow two memory sticks per channel.

You four channel mean like those in x99 mobos or four slots in H170 mobo?
Does one stick per channel will give the same bandwidth or less than two sticks per channel in H170?

On most. but not all, new Skylake boards, and all the X99 boards, the chipset is configured for quad channel memory. Some boards have only two slots, so can only do dual channel, some boards have four slots and can do quad channel, and some boards have eight slots and can do quad channel with two sticks per channel. Bandwidth and channels are different things. The more sticks in a channel actually lows things down a little due to memory controller overhead.

I investigated this over the summer on a dual channel board using 1x4, 2 x4, 1 x 8, 2 x 8, and 2 x 4 + 2 x 8 configurations. For identical memory, the 2 x 4 configuration was the fastest, by a little bit, in circumstances where the amount of memory was not limiting.
