All errors are 0x00000050: PAGE_FAULT_IN_NONPAGED_AREA Requested data was not in memory. An invalid system memory address was referenced. Defective memory (including main memory, L2 RAM cache, video RAM) or incompatible software (including remote control and antivirus software) might cause this Stop message, as may other hardware problems (e.g., incorrect SCSI termination or a flawed PCI card). Three specifically cited memory corruption with the other two citing the OS drive ntfs.sys. I think it is time to contact Gigabyte about your memory issues especially with voltage. Tell them your error codes and the minidumps were read with multiple memory corruption reads but that memtest showed no actual corruption. Also make sure you tell them the different steps you attempted to rectify and how you came back to find the memory voltages were changed without any doing on your part.
