MSI B350 Tomahawk Arctic RAM stuck at 2133Mhz and random Crashes

So I recently built a new computer using my old hardrive and PSU(only a few months old), using the new Ryzen 5 1500x however my ram is stuck at 2133Mhz and when I go into the BIOS and change it my computer will boot up and CPU-Z will say im still at 1066Mhz (2133Mhz overall) When I go back into the BIOS it says adjusted speed 2133Mhz as well as this when im playing specific games for example saints row 4 my computer randomly crashes to a black screen and then my monitor shows no input(computer fans still spinning and lights still on inside).
PC Part list:

Ryzen 5 1500x (stock speed and stock cooler)

MSI B350 Tomahawk Arctic

Corsair vengace lpx 16gb 3200Mhz(CMK16GX4M2B3200C16) (hynix manufacturer supported says samsung)

Asus DUAL RX480 8GB



Corsair CXM 750W

More Info
On MSI memory compatibility same stick in different color CMK16GX4M2B3200C16W /R instead of CMK16GX4M2B3200C16 (black version) and it mentions chip set Samsung whereas i have a hynix chip set checked using SIV(system infomation viewer). There are two versions of this RAM apperently -CMK16GX4M2B3200C16 ver5.39 with SK Hynix
-CMK16GX4M2B3200C16 ver4.31 with Samsung B-die
Should this make a difference and im not sure what i can do about this.
This link shows a discussion about this and some running the same memory as me on a non arctic b350 (dont think that matters) at 3200mhz stable.

Cheers for the help.

    I have fixed this problem by undervolting my GPU to -10% power and setting, settings to dynamic in wattman. As well as this I had a faulty CPU power cable.
