Soldato
Yep tried stuff like first, won't even boot!. I bought it used from amazon...Starting to think it was bad chip and that's why it was returned. Also notice a bit of surface damage on the cpu
When I took the stock cooler off it left the 4 corners looking a bit damaged if thats what you are talking about.
Try 1.35v with 37 and set cpu fan too 100% and monitor temps.
