If they are a matched pair return both if you get failures - they will have warranty.
If it's not the northbridge I'm guessing something else is heating up, each stick passes fine when tested alone. However when the errors do start each stick will be bad.

It's been okay for 3 days straight now I've left the aggressive fan settings on for my gfx card, and left the tt120 fan at 100% but it's pretty noisey.
