I just put my new 13700k build with DDR5 (2x16GB) together and checked it in CPU-Z. I am pretty sure I installed the DIMMs correctly in the slots to get dual channel. But in CPU-Z it doesn't say dual channel, but instead it says "4 x 32-bit". I assume that is a new way from CPU-Z to fill that field and I guess it means dual channel. Can someone please confirm?
