CR2032 CMOS batteries normally last between 3 and 5 years before they need changing. On a brand new motherboard they should be fine.
If you have a multimeter, a new CR2032 will be 3.25V out of the board. Anything less than 2.50V and I'd change it.
If your system is unstable, disable any XMP/EXPO/DOCP memory overclock and set the frequency back to the JEDEC defaults.
If you've got 4 DIMMs installed, they will be less stable at high XMP frequencies than 2 DIMMs. To improve stability, fit only two DIMMs.
Do not assume that just because your motherboard supports 6,000MHz OC and your RAM is rated at 6,000MHz, the computer will start up, let alone run smoothly at this speed. You may never reach the maximum speed rating of your RAM and retain stability.
If you're applying any overclocks on your CPU and GPU, disable them both. Take everything back to stock (lower speed). That means no PBO on an AMD chip.
As others have said, boot the PC from a MemTest86 USB key and test your RAM. You might have a faulty DIMM.
You shouldn't have to disable any cores in your CPU. All that does is to reduce power dissipation. With adequate cooling, the CPU should throttle normally on all cores, when it gets too hot (90/95C AMD, 100C Intel).
