If I'm still experiencing stability issues, could it be my CPU?

I have 13 cards and plan to add more, up to 19. My virtual ram is like 4TB so that can't be the issue. But my CPU is a G4620 and ram is just 4GB. What do you think?

cpu shows 30%, ram shows 70%. It's only a problem because when the miner sort of just stalls, the autoit thing doesn't reset the miner, other errors are sorted fine.

just noticed i still had 100/400 overclocks on my 1080tis, perhaps taking those off will solve it
