Im using two slots with 2x16GB vengeance LPX 3200mhz DDR4 and considered buyng another 2x8 of the same type. I got the motherboard MSI z370 gaming pro carbon that supports up to 64GB RAM. I'm using an i7-8700K CPU.

Could this cause any issues and why if it might do?

They wouldn't run in quad of course, so you will get two times dual-channel.

But lemme ask,

Why an earth would you want 64gb of ram? Are you editing 4k videos allday long?

Would it be an issue that they would run in two times dual? Is it only speedwise or?

It would not use it's full potential. If you editing 4k-8k raw footage go foe 2x32gb sticks. If you play only games 32gb is more than enough even for 4k games

Yeah questioning why that RAM upgrade is necessary is the most important part. Mixing different RAM sizes could have a lot of unintended consequences as well. If you do try it d1no make sure to run some memory stress tests (like memtest86).
