Hi guys,

I was testing thermals on my late 2015 full spec iMac and while using the "Yes" command in Terminal and using Intel Power Gadget to monitor CPU clock speed, I noticed my iMac never reaches 4.2Ghz like it is supposed to with it's Intel Core i7 6700K.

I tried inputting "yes" once to stress one core, 2 cores, etc, and all results are the same.

Is this normal for this iMac model and CPU? Does anyone else's iMac or any kind of Mac also not Turbo Boost?

I'm a bit mad about this, considering Apple advertises that the CPU Turbo Boost's to the advertised speeds, yet never reaches them. It never even spikes to 4.2Ghz at any point in time for any reason. It's like they disabled it.
