Instability and desktop freezes while playing Minecraft

Started happening a few days ago, when my whole desktop freezes I just no longer get display output, it does not appear the machine is running anymore, since I don’t get anything like audio output. Also after rebooting the journal just abruptly ends with no mention of the event.

When it doesn’t freeze my entire desktop it’s usually an Nvidia error in the journal followed by many programs segfaulting.

Here is one such example: 497650e

Does anyone have any idea of what I can do?

I believe I’ve fixed this by clocking my RAM to 6000Mhz UCLK=MCLK instead of 6200 UCLK=MCLK. So far been stable for over 24 hours. Odd that this wasn’t an issue prior since that was set that way months ago.
