PC Randomly Turns Off After Installing More RAM

As the title says, my PC will randomly shut down and restart itself after I installed more RAM yesterday. I made the sure to buy the exact same model of RAM as the one I already have installed (CORSAIR CMK32GX5M2B6000Z30). The original sticks were DDR5 2x16 6000MHz CL30 taking 2 DIMM slots and the new ones are the exact same, now taking all 4 DIMM slots. I believe it has something to do with the EXPO setting I enabled in the BIOS, but when I ran TestMem5 it showed no error. I am thinking of running Memtest86 to see if anything changes regarding errors but I have a few questions regarding it. First, do I have to take out 3 sticks and test 1 at a time or can I leave all 4 sticks in and run the test? Second, do I have to clear the CMOS on my motherboard before running the test?
SPECS:
AMD Ryzen 7 7800X3D
Arctic Liquid Freezer III 360mm
ASUS TUF GAMING B650-PLUS WIFI
CORSAIR VENGEANCE DDR5 2x16GB 6000MHz CL30 (2 sets)
NVIDIA RTX 4070 Ti SUPER
WD SN770 1TB NVMe
WD SN770 2TB NVMe
CORSAIR RM850e

4 sticks of DDR5 at high speed is just not going to run stable if at all, you may be able to get 4 sticks to work at 4800-5200 with manual tuning

Oh wow, I wish I had knew that before buying but oh well. Would I just change the frequency (MHz) or would I have to change the timings as well? Also, with lower frequencies would there be a noticeable dip in performance during gaming?

DDR5 is unstable with 4 sticks of ram. Unless you underclock it. I had success with 4 sticks, but the speeds were 4200mhz, which was the only way to make it stable. If you just want to upgrade the capacity of your ram, run 2 sticks to get its advertised speed. If you just want it for aesthetics, you will have to run it at slower speeds than advertised to be stable.
