Hello.
After fresh windows install found the problem. (moved windows to new NVME) .
System Freezes upon activating Sensors. (Particulary seems to be LM75 ).
Worked fine on previous system installation.
No other problems detected.

Tryed: disabling PCH device/reflashing bios.
Still no luck.

Looks like there's some issue when accessing the PCH Thermal Device.
Does the BIOS offer some option to disable this device or change some settings?

Changing 3 settings at once seems to help:
PCH mode: continuous -> quiet
State after G3: -> Last state
PCH Thermal device device: enabled -> disabled (tried this option alone before = not worked ).

Will play with this options a bit more. Not sure which one helped.
Any idea on if its software or hardware problem?

I'm not sure why exactly the problem happens, all I can see is that it occurs when HWiNFO attempts to read temperature from the PCH Thermal Device registers.
Maybe a BIOS update might fix this issue.

Let us know if you find a solution. Perhaps I could add some workaround for this system...

Hello, I also have a Jingsha X99 Dual and the only change I had to do to not crash when reading sensors in HWiNFO64 was to change the PCH Mode from it's default value "Continuous" to "Quiet".

I have some odd temperature readings but I believe it's a common issue for this Chinese motherboards, I will ask the manufacturer.

Is there anything I can do to help find the issue about the PCH thermal device crash when in "Continuous" mode?
I was reading the following Intel document but not sure what could be the probable cause: https://www.intel.com/content/dam/w...es-chipset-on-package-pch-datasheet-vol-1.pdf

That's an interesting observation!
You might try to attach two HWiNFO Debug Files - one in Quit and other one in Continuous mode with crash. I could then check the details if I can see some difference that would allow me to determine a workaround.

Those odd sensor values are because this board requires sensor adjustments, but as long as I don't have reference values it's almost impossible.

I have no idea what is going on now, I switched back to "Continuous" mode and it's not crashing anymore, even after a full shutdown when changing the BIOS settings.
I will try a full BIOS reset later to see if it crashes.

Also I forgot to mention I'm getting the "PCH Temperature" fine.

I have asked the manufacturer to provide me with the sensor adjustment reference values, I will let you know if I have an answer.
