Hello,
First of all, 1.45 volt is a dangerous value, standard is 1.200V, and 1.350V is already 12% higher, and you cranked it up 24%.
compare it with your wall socket, who would provide 258V instead of 230V, or with a 24% increase 285Volt, you wouldn't do that to your TV or PC.
The memory controller is integrated in the CPU, it is not on the board, and in this case it seems the XMP profile is basicalyy not compatible with the memory controller inside your CPU.
XMP is overclocking for dummies, it is a set of values SUPPOSED to work on all of the thousands of combinations of CPU, Chipset, and motherboard.
It is not guaraanteed to work.
And corsair is NOT a memory manufacturer, but a memory assembler

Like most other brands, they buy any PCB and chip, they can lay their hands on, and solder that onto the PCB.
But since introduction of DDR4, there is a big shortage of chips, and as long as the speed, and primary timing stays the same, they keep using the same partnumber.
I have seen people who bought 2 kits of 2 in one buy, and one kit had 512MB Hynix chips, and the second had 1GB chips from another brand, both kits however had the same partnumber.
As far as I know, only Crucial and Samsung are true memory manufacturers, but I have seen a lot of people go for Patriot Viper kits, and they seem to always work with XMP.
3200MHz is the optimal value, you can sue faster memory, but it will not improve your overall performance, unless it has a lower latency timing.
When you want to know which settings are best for your current memory, download thaipoon burner, and ryzen DRAM Calculator.
Google for ryzen DRAM calculator, it will give lots of tutorials, on how to use it
