Snowman, nice clocks. Unfortunately I think your chip might need more volts to be Intel burn test stable. Can you confirm? Is that an ES chip?

Oh and sorry unclewebb! I use coretemp because it has a LCDC plugin for my LCD on the front of my case. But I want you to know that I prefer realtemp.

So here is my retail 860 chip, which I think is nearly identical to the ES chip that Snowman has. At 4GHz it only took 1.23vcore for basic stability, but 1.32 to be stress test stable.
