Dual vs Quad Channel, any impact on which ram I can use?

Hi,

So I'm building a pc, and I haven't bought my ram yet. I was initially going to buy 2x8GB ramcards, but as 1x16GB is the same price, and makes upgrading later less of a hassle (and cost), I've been considering buying a 1x16GB card instead. But while searching for information about any performance differences (purely out of curiosity), I came across a few posts—I don't know where now, as it's been a few days—which stated something along the lines of 16GB requiring quad channel ram support; and after reading about quad vs dual channels, I'd also become concerned about whether 4x16GB ram, or 4xanyGB ram is off the table (all this despite having 4 slots and a board which lists 64GB max ram in it's specs). I emailed tech support while waiting for my account here to be verified, and received this response:

"If you wants quad channel setup, please use X99 motherboard with processor that supports it.
Dual Channel: Dual-channel-enabled memory controllers in a PC system architecture utilize two 64-bit data channels: 3200*2=6400 total bandwidth
Quadl chnanel - supports arcitecture that utilize 4 channels: 3200*4=12800"

What I'm taking from this, is that dual channel supports 64GB of ram, and quad channel supports double that. Is that correct?

Please help.

Thanks!

I didn't find the right solution from the Internet.
