mV Boost value isn´t applied
The mV Boost feature works correctly on my 10850K. This might not work correctly or at all on 10th or 11th Gen mobile H series CPUs. In theory, this setting should be locked out if the CPU does not support it. Based on user feedback so far, I do not think any of the H series CPUs support mV Boost.
The problem this feature tries to solve is that you might be able to get away with a big undervolt when a CPU runs at full speed but this same undervolt can cause a BSOD when the CPU is lightly loaded. I thought being able to boost the voltage curve a little at low frequencies might help the cause. When I originally added mV Boost, I did not realize that the H series do not seem to allow this level of control. This experimental feature might be removed in the future if I ever find something to put in its place.
Newer CPUs have two separate Speed Shift EPP registers. I do not have access to anything newer than my 10th Gen desktop CPU so trying to get this feature working correctly for both old and new CPUs has been a challenge. If you check the Speed Shift EPP box on the main screen, can you adjust the EPP value here and does the requested EPP value show up in the FIVR monitoring table? If this works then I will probably leave this as is.On 9.4.2 the reported value changes accordingly to the power plan.
I always move the Voltage slider all the way to the left and set this to Default when I am using Adaptive mode. I am not sure if any Intel CPUs allow one to set a voltage value when in Adaptive mode. ThrottleStop correctly sends this request to the CPU but if the CPU does not understand the request, it simply ignores it. Without access to a wide variety of hardware, I tend to leave things like this unlocked so users can experiment. If something does not work, do not use it.any core voltage value set in adaptive mode isn´t applied
Newer CPUs do not use the Non Turbo Ratio for CPU speed control when Speed Shift is enabled. That is why the Non Turbo Ratio setting is now greyed out.the Non Turbo Ratio option inside the FIVR window is greyed out.
I think the Extra Turbo Voltage feature only applies to the 2nd and 3rd Gen CPUs. That is why this setting is greyed out on newer CPUs.the Extra Turbo Voltage option is greyed out
