Nope, this is my first C3, it's 0945DPAW. I think it's a high leakage chip, because I hardly make 4.1GHz Prime stable on water or it takes a big bump in voltage, but it scales nicely with more of it It has max stable NB of around 3050MHz, but since I was using the box cooler, I couldn't push it further. Wonder what it can do on ln2, lol. The 1001 chip is waiting on the shelf, it was running fine at 4.2 before I pull it off, but I didn't have the chance to test it good. We'll see if it scales with voltage, or not.
