MSI GL65 9sdk-039 Memory upgrade question

[Gakidou]

I have upgrading questions for my laptop. It's the MSI GL65 9sdk-039 with an I7-9750h, 16gb of ddr4 2666 cl19 ram, gtx 1660ti 6G GDDR6, 512 nvme m.2. Everywhere I look for upgrades for the ram on this laptop say nothing above 2666mhz on account of the processor, but I've also seen a few reddit posts that I could use 3200mhz using intel XMP profile and get up to the rated 3200mhz. I need to know for sure if my laptop can handle it and actually achieve this and also most of the ram in that range is 1.2v and one with 1.35v with a CL of 16, but I don't know if my cpu can handle the higher voltage or if i should stick with the lower 1.2v. I'd appreciate input on this topic

1.35V is fine for DDR4, it's a pretty common XMP voltage.

True, I've seen as much for the most part, but I've read that if the voltage of the ram is higher than what the cpu/apu uses it can cause damage to said chip over time. Do you know if this is true? If not then my problem may be solved if my particular laptop has XMP 2.0 capability, which I assume most modern day laptops and desktops do
