Do you not mean overclock/overvolt? I think undervolting was underclocking.

Have you tried returning it back to it's suggested range (from what the manufacturer suggests to use) and tested it out after doing that?

Hope you aren't using MSI afterburner? Sometimes this software will glitch and keep reapplying your old settings even if it crashes your PC, I suggest you uninstall the software you use for under clocking first which will set things back to default

I don't understand what did you do? If you have changed the BIOS settings, then download the latest version from the official site, if you did not make a backup before changing it. If you changed the settings using programs, then set the default settings.
Are you worried about the temperature of the memory or video chip?
