Can I set per core voltage offset by ThrottleStop

[turtlemark]

ASRock mb supports "per core voltage offset". User can set voltage offset for each core separately. It looks like XTU also supports this function.
Is there any way, such as directly editing the ini file, to set per core voltage offset by ThrottleStop? I can understand operations for computer such as bitwise operations. Thanks!

I set the most favored two P cores and all E cores -0.165, and other P cores -0.125. When Windows started, ThrottleStop CPU Core Offset shows -0.125 and -0.165 at first, then stays -0.165 while most cores are parked.
It looks like the "per core voltage offset" data is stored somewhere else and picked/used when the relative core is active/unparked.

You will have to continue using ASRock OC Tuner or Intel XTU if you need the "per core voltage offset" feature.

I will be adding Voltage Frequency Point tuning to ThrottleStop in the near future. Only the K and HX processors support this feature.
Hopefully a new TS version will be available next week.

Edit - Found out that the 12th Gen and newer CPUs use 11 V/F points for the cores and 8 V/F points for the cache. The 10th Gen used 8 V/F points for both the core and the cache. Also found out that the core and cache offsets can be set individually. It is a work in progress. Should be useful when done.

Edit - Testing in progress. All new features are up and running and working fantastic!

VF Points tuning is exciting!
By the way, as far as I know, the way to set voltage offset, no matter what mode, is writing some value to registers. I have read a book about MSRs, provided by Intel, but it was a long stroy. Would you mind give me some hint to the target? Thanks!

Will it work for i9-9980HK?

I think VF point voltage control was introduced starting with 10th Gen. I do not think it will work on a 9980HK. I will send a download link to you when it is ready to be tested.

If it doesn't work on the i9-9980HK it will be sad for me.

It doesn't work on XTU and so I'm not very hopeful...

On my i9-9980HK the maximum stable undervolt is -110mV in cache up to 4.1GHz.

At 4.2GHz (default all core maximum clock) and 4.3MHz this value drops to -102mV.

At 4.4GHz it already rises to -125mV, at 4.5GHz it is -140mV, at 4.6GHz it is -150mV and then it starts to decrease with -130mV for 4.7GHz...
