Unexpected CPU slowdown

[StormX]

Hey guys! 

Lately I was doing some benchmarks with Cinebench R15 and I noticed that when on idle the CPU runs at normal clocks but if I put some heavy workload on it it starts to throttle. I tried disabling c-states and speedstep. Tried increasing the volts enabling/disabling XMP increase cache ratio and tried what I could in AIsuite 3

 

My specs are the following:

Intel i5-6600k CPU

Corsair cs-650 PSU

16 GB DDR4 2133Mhz RAM

Asus B150 Mobo(had no idea that I wont be able to oc on a B series Mobo) 

 

Thanks in advance!

what cpu cooler are you using, a i5 is not a heavy workload cpu.

I got a 240mm fan on the cooler. Not sure in the brand but I think its CoolerMaster. And under heavy workload i mean video rendering, Cinebench, Aida64 anything that will make CPU usage be 100percent

still not the best idea rendering with an i5.

I was just benchmarking it. I usually just use it for gaming
