The 032623-8187-01.dmp is clear-cut, it's a DRIVER_VERIFIER_DETECTED_VIOLATION showing a code integrity issue, meaning that a driver tried to access the wrong page type (executable instead of non-executable). This is clearly a driver error.
The call stack shows a call to Rz_Dev.sys...

Argument 2 of the bugcheck (0xFFFFF804CD8224CF) is the address in the driver where the failure occurred, identifying the module name confirms that the problem happened in RzDev_025d.sys...

Information from resource tables:
There may be a more recent update for this Raxer (mouse?) driver? This is certainly a flaky driver and it does need either updating or removing/replacing.
The other two dumps are very similar, they are both MEMORY_MANAGEMENT bugchecks with an exception code indicating a page table problem. Argument 2 in each dump provides the virtual address where the bugcheck happened, by displaying the virtual to real address mapping for that address we see that there is indeed a problem...

This could be a RAM problem as you suspected, but it could also be a rogue driver. Both these dumps were performing graphics operations, the DirectX kernel driver dxgkrnl.sys is called in both. Whilst there is no evidence of the Razer driver RzDev_025d.sys being called in these dumps I don't believe in coincidences and I think it reasonable to lay these two BSODs at the door of RzDev_025d.sys.
