I am interested to build a new desktop PC as follows: Intel G4400 + ASUS H170 Pro + I already have MSI R7770-PMD1GD5 AMD Radeon HD 7770 1GB GDDR5 128bit.

At this point I have some concerns related to the RAM choosing process. I know this motherboard supports up to 64GB DDR4 RAM (4 slots) @2133Mhz.

Is that OK if I'll buy a single RAM stick (16GB) and if it's not enough after a while to buy another one (using it in Dual channel) or the dual channel concept include some pairing factory stuff inside the RAM modules?

How about the other technical specs of the RAM module, not so sure about Timing (e.g. 12-12-12-35) Cas Latency (e.g.12) Voltage (e.g.1.2V) how these should pair with the motherboard?

Could anyone guide me please in a few words? Thanks.

Asus QVL of memory list for that board.
Buy 2133MHz 1.2 volts in a 2X8gb set not a single with what your using you will never need 32GB of memory or probably even 16, but you could use over 8 so get 16.

Thank you for your feed-back, Actually I am trying to understand some things :)
I've checked the Asus QVL of memory list for that board and I still have some questions if you dont mind.
I've find 3 options by Kingston as follows:

According to part picker,
HyperX Savage Black 16GB DDR4 2133MHz CL13 Dual Channel Kit
HX421C13SBK2/16
•JEDEC: DDR4-2133 CL15-15-15 @1.2V
•XMP Profile #1: DDR4-2133 CL13-13-13 @1.2V

and
FURY Memory Black - 16GB DDR4 2133MHz CL14 Dual Channel Kit
Version 1 HX421C14FB2K2/16 tRFCmin 350ns(min.)
• JEDEC/PnP: DDR4-2133 CL14-14-14 @1.2V
• XMP Profile #1: DDR4-2133 CL14-14-14 @1.2V

Version 2 HX421C14FBK2/16 tRFCmin 260ns(min.)
• JEDEC/PnP: DDR4-2133 CL14-14-14 @1.2V
• XMP Profile #1: DDR4-2133 CL14-14-14 @1.2V

As far as I've read they don't have to be necessarily listed on QVL but, the first one CL13, not so sure why, it's not even recommended by Kingston memory selector if we select Asus H170 Pro motherboard.

which one should I choose?
Thanks
