Run Heaven or luxmark in a window with cpu-z open next to it, You''ll see what the CPU clock does then under load.
I've got CPU-Z installed which is showing the CPU clock etc, but i'm struggling to find a program which shows the CPU & GPU temps. I've got CPUID HWMonitor, which is giving some figures (TMPIN0) at idle 33'c, running Heaven Benchmark max 42'c (using only 1/3 to 1/2 of CPU) and dropping to 3Ghz...strange behaviour.
Also the iGPU temp is around -2'c!
PS: Just ran Warframe in window mode and that stayed 3.6-4.0Ghz, ran Crysis and that dropped to 3Ghz. What i don't understand is when the CPU is 'idle' in windows it returns to 4.0Ghz! running backwards compared to an Intel.
