Question 2x32GB vs 4x16 GB? 4K Video editing/Gaming

[notapcguru]

Hey Guys,

This system is for 4k video editing and gaming. Based on my research so far, I'm going with the lower speed 2666 RAM because I want absolute rock solid stability, but I'm still not sure on whether I lose any performance by using 4 sticks of 16GB versus 2 sticks of 32GB each. Would 4 sticks of 16GB would work the same? I'm shooting for 64GB total RAM (Color: White modules).

Here's the RAM I have picked out currently:
RAM: https://www.amazon.com/dp/B01EI5ZK7...colid=CPZ53GKIGW4E&psc=1&ref_=lv_ov_lig_dp_it
Corsair Vengeance LPX 64GB DDR4 2666 C16 for DDR4 Systems - White

PC Part Picker is also giving me this warning: Note:Some physical dimension restrictions cannot (yet) be automatically checked, such as cpu cooler / RAM clearance with modules using tall heat spreaders.

I feel like it's just because this particular RAM/Heatsink/Mobo combo hasn't been "officially" cleared, but I am thinking it won't be an issue.

Thank you for your time!

Your CPU has a dual channel memory controller. The best choice is always to match the number of DIMMs to the number of memory controller channels. Two DIMMs is optimum.

PC Part Picker only offered two options, one of them being this one:

I think this might be my best bet, even though I wish I could have white modules. Thoughts?
