CPU Speed Going Down?

[Appleboy45]

Just curious. I have a Intel Core i5 6600K clocked at 4.5 GHz. In CPU-Z and Task Manager, I am not surprised it  drops or rises a few MHz in the CPU Speed, but is it normal for the CPU speed to drop a couple GHz and then go back up?

Depending on the load, it may drop all the way down to 800 something MHz.

my cpu drops as low as around 200mhz but it clocks back it when there it is needed

Do you have a Skylake CPU with Windows 10?

Interesting. My Ivy Bridge CPU only goes down to 1.6GHz when idling.

@Appleboy45 Mine i5 6600k is at 4.5ghz and will go all the way down to 800mhz if I'm just sat messing about on the desktop. If you running windows and you have the power settings set to balanced it will do this but on mine if I set my power setting to performance in windows it will stay at a constant 4.5ghz

It should only go down to 800, as that's the lowest multiplier available to the CPU last I checked.

I was asking because at least some Skylake CPUs can drop to 400MHz.

The processor in question is an Intel Core i7-6600U, with a base frequency of 2.6 GHz, and turbo frequency of 3.4 GHz. Despite the base frequency being rated on the box at 2.6 GHz, the processor can go all the way down to 400 Mhz when idle, so being able to ramp up quickly could make a big impact even on the U-series Skylake processors.

@Godlygamer23  Yes you can set to 400mhz , 800mhz or 1GHZ all within the BIOS on the z170 board I have.

might be a windows task manager glitch then

it's normal, your CPU is just saving energy when it's not under heavy load...

0.136V at idle. That's just beautiful.
