To be fair they are all low leak chips the 1800x should however be more on the high leakage side than a 1700. I mean that is how binning works...

If you really look at the graph kicked out by stilt these chips shouldn't be clocked this high from the factory anyway. The vast majority of 1800X's would be equal to an Intel bin in the 3.3-3.4 range which is why they clock terribly.
