For 6700K (and likely other CPUs too) there is a CPU current limit option that can be set to 255.5 which means no current throttling

But why 255.5 and not 256 or 300? What's the deal with that 0.5?

So really what is the "physical" meaning of 255.5?

Is it in Amps? Like If i set it to 100 does it mean 100 amps maximum?

And if it's in Amps, does a value of 0.5 Amps really matter in that scale?

  1. The Voltage - the electrical tension between two points, needs to be high enough for the logic components to operate at the frequency and temperature you want them to.
  2. The Current - the flow rate, goes up as more logic (and more complex logic) is working at any specific moment.
  3. The Wattage - the total electrical power consumed, dead simple: power (Watts) = current (Amps) * voltage (Volts)
The physical meaning of 255.5 is Amps, you can multiply it by your set CPU voltage and you'll get maximum power your CPU is allowed to draw.

255.5 Amps at 1.2 Voltage is so high, your CPU will never hit that ceiling.
