If you want a steady multiplier then you need to turn off all of the C states including C1E, C3, C6 and C7. Most laptops do not let you toggle the C States on and off in the bios but there is a registry mod you can use if you want to see what your laptop is like with the C States disabled.
Code:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Intelppm
Go to the above registry key and set Start to 4 to disable the C2/C3/C6/C7 low power core and package C states. Default value for this is 3. You will need to reboot to see any change.
After doing this, ThrottleStop will show you that your CPU is consuming more power and running hotter. You can go back to the original value anytime you like.
After you disable the C states, the 7700HQ will not have access to the 35, 36, 37 or 38 multiplier so in any single threaded task, your CPU will run slower.
Your screenshot shows that you have Speed Shift enabled (SST in green). Windows 10 uses this on many newer CPUs. When Speed Shift is enabled, the older SpeedStep (Set Multiplier) will not do anything. You need to set the Speed Shift EPP value to 0 for maximum performance. You can also use the Speed Shift Max value to cap the maximum multiplier.
Edit - The result. A nice steady multiplier across all threads even when the CPU is idle. Idle temps are up 15°C even with the fan spinning a little faster.
Compare that to having C states enabled. Now the CPU can access its higher turbo multipliers, it consumes less power and runs cooler. For a laptop, I like C states on. There are some unique situations like music production where disabling the C states to minimize latency can be a good thing.
