burebista, nice to see you here!

Well, I tried increasing vTT, vPLL, vcore, vDIMM, vNB and even vSB. I set Performance Level to 12, then 13. I even uninstalled SixEngine. Nothing seems to work, the system isn't stable at 2.83 GHz. I'm going to climb back to 3.4 to see if I'm stable again, as I was before.

Any other suggestions ?
