Get the spit bowl ready. This story is bound to get you gnashing your chompers and leave a bad taste in your mouth.

A dentist in Wisconsin has been found guilty of deliberately breaking his patients’ teeth with a drill so he could collect millions of dollars to repair the damage with dental crowns.

The alleged scheme by licensed Grafton dentist Scott Charmoli, 61, appears to have begun in 2015, when the number of crowns he installed abruptly increased. In 2015, Charmoli installed 1,036 crowns, well over the 434 crowns he did in 2014. Amid the royal boom, his income increased by more than a million dollars, going from $1.4 million in 2014 to $2.5 million in 2015, according to court documents.

AMD’s Ryzen 7 5800X3D promises to be one of the company’s fastest gaming CPUs, and it’s one of the last high-end chips that will grace the AM4 socket before Ryzen 7000 CPUs come out later this year. But its experimental new 3D V-Cache stacking technology comes with one negative side effect: This will be the first Ryzen CPU that’s incapable of overclocking.

According to PCWorld, AMD Marketing Director Robert Hallock says that this is because the processor’s voltage limit is locked to 1.35 volts, a bit lower than other Ryzen 5000 chips. A lower voltage for the CPU cores means they’ll generate less heat, presumably creating a bit more thermal headroom for the 64MB of additional L3 cache memory that the 5800X3D uses. It would also explain why the 5800X3D’s clock speeds are a hair lower than the standard Ryzen 7 5800X.

Hallock said this wouldn’t be true of future 3D V-Cache CPUs, so if we do see this technology re-used in Ryzen 7000 chips, they should still be overclockable, as most other Ryzen processors have been. You can also try to squeeze some extra speed from the 5800X3D with memory and Infinity Fabric overclocks.
