Issues with ram

Yooo. Everyone was super helpful before hoping I can get some knowledge from the community.

I have a : 1.AMD Ryzen 7 7800X3D 4.2 GHz 8-Core Processor 2.Gigabyte B650E AORUS ELITE X AX ICE ATX AM5 Motherboard 3.CORSAIR VENGEANCE DDR5 RAM 32GB (2x16GB) 6000MHz CL30 Intel XMP iCUE Compatible Computer Memory - Black (CMK32GX5M2B6000C30)

Originally I wanted just 32gb but feeling flush and wanted an xmas present I bought the same ram again.

Since install i have had nothing but crashes on all my games.

I can't work out the issue. Attached only 16gb and it's now 48gb and its fine. Mobo works upto 192gb so isn't an issue there.

Could it be related to voltage. Mobo doc states can be 1.4v for the ram and I have them at 1v? Or Could it be related to versions of the ram.. Such as same model CMK32GX5M2B6000C30 but the newer pack has a different version therefore i need to install them in the main slots and older ram in the extra ram slots?

Any suggestions is welcome I'm unsure how to fix the issue.
