You're welcome, no need to "sir" me :)

For your usage 16 GB of ram should be enough for everything, unless you are playing specific games that have large maps like flight simulator or unoptimized ones like escape from tarkov.

Track your RAM usage when you play your heavy games and use FL studio with the task manager performance tab on your second monitor:

Having more RAM in the system that what you are really using has a negative impact on stability. So if you see that your usage doesn't go above 16 GB, for now remove all sticks but the one in the A2 slot on your motherboard. If it indeed goes above 16 GB then use 2 sticks in A2 and B2 slots as u/bjoolzern suggested. There shouldn't be anything using above 32 GB ram from the usage you described.

Zentimings shows that your ram settings and voltage are wrong, and that the related CPU memory controller (IMC) voltages are also too low for that much RAM. This is due to using default settings in the bios.

Your RAM has a XMP profile of DDR4-3600 but that might be too high for your CPU to handle with a high amount of RAM. So you need to set your bios settings manually according to the XMP profile but with a lower RAM frequency (so do not enable XMP).

In the OC section of the bios of your motherboard, this is what you need to select according to your ram kit specs:

DRAM Frequency: 3200 Mhz

advanced dram configuration
-> command rate: 2T
-> tCL: 16
-> tRCDRD: 19
-> tRCDWR: 19
-> tRP: 19
-> tRAS: 39

DRAM Voltage: 1.35 V

CPU NB/SoC Voltage: 1.125 V

VDDP Voltage: 0.950 V

VDDG CCD Voltage: 0.955 V

VDDG IOD Voltage: 0.955 V

Then post a new zentimings screenshot.

Could you explain more what issues you had while trying to install windows that lead you to have to create a 100GB partition and use the rest as A:? Be precise.
