Q270 Chipset supporting Dual Channel?

[fromscratch]

Hi,

I have a HP EliteDesk 800 G3 Mini, the version running on 65 W and the i3-6100 processor.
Intel specs says that this model runs on a Q270 chipset mobo and has a capacity of 32GB. I opened up the housing and saw a single 8GB RAM stick next to an empty slot. So this Mobo has two ram slots.
Now I looked up the Q270 chipset and the specs state 2 slots per channel. So if the motherboard of the PC has only two slots and the chipset states 2 slots per channel I assume that this particular motherboard has only one channel and does therefore not support dual channel? My logic is that for a dual channel mobo with 2 slots per channel there have to exist at least 4 slots on the motherboard (regardless of how much one would actually use, 4x4GB or 2x8GB for example).
For now I cannot connect the PC and run CPU-Z to give the precise motherboard model number.
But I am just wondering if there are actually motherboards that do not support dual channel anymore.

Cheers

For each channel in a modern PC, you need an individual stick of RAM. HP chose uses two DIMM slots instead of four to save space.

Specifications read:
The HP EliteDesk 800 G3 Business PC supports DDR4 protocols with two independent, 64-bit wide channels each accessing one or two DIMMs.

To me, "two independent, 64-bit wide channels" indicates Dual Channel.
