Got sick of it, ask the store for a RMA. Got a new one week later. It was perfect, clocked at 350/1000. I checked with coolbits how high it overclock, it goes to 427/1170 without any artifacts! I run it at 350/1000 though, I'm not into OC. It's been running nicely with no problem for the past 3 months.
