SVI2_Core & SVI2_SoC mixed up on ASRock X470 Taichi #7

Closed RichGuk closed 4 years ago

RichGuk commented 5 years ago

My Core and SoC seem to be the wrong way around; this is on a 3700x and ASRock X470 Taichi. It was correct when the CPU was in my old Asus X370 Prime board but on ASRock X470 Taichi it appears swapped. I have re-run sensors-detect etc. Unsure if I simply need to just rename some labels? If that's the case close the issue.

zenpower-pci-00c3
Adapter: PCI adapter
SVI2_Core:    +1.02 V  
SVI2_SoC:     +1.45 V  
Tdie:         +33.5°C  (high = +70.0°C)
Tctl:         +33.5°C  
SVI2_P_Core:  26.63 W  
SVI2_P_SoC:    6.28 W  
SVI2_C_Core: +25.98 A  
SVI2_C_SoC:   +4.33 A

Shots of HWINFO:

hwinfo-1 hwinfo-2

and attached the debug info from it. HWiNFO64.DBG.zip

Hello, thanks for your report. This is indeed a bug. Seems like some motherboards are reporting SoC and Core values in swapped addresses. Unfortunately AMD did not published any documentation for this so I do not how to detect which address is correct. Also Amps values do not seems to be accurate.

As a workaround you can actually rename labels in lm-sensors. You can do it by creating file /etc/sensors.d/zenpower with contents like this (this will swap SoC and Core voltage):

chip "zenpower-pci-*"
    label in1 "SVI2 SoC"
    label in2 "SVI2 Core"

To add another data point: I have the same problem on MSI B450 Gaming Pro Carbon AC with Ryzen 3600 cpu.

zenpower-pci-00c3
Adapter: PCI adapter
SVI2_Core:    +1.08 V  
SVI2_SoC:     +1.44 V  
Tdie:         +61.4°C  (high = +70.0°C)
Tctl:         +61.4°C  
SVI2_P_Core:  31.48 W  
SVI2_P_SoC:    9.81 W  
SVI2_C_Core: +29.10 A  
SVI2_C_SoC:   +6.85 A

I think power and current values are also swapped (it's SoC where I'd expect Core).

I have another system with swapped values: ASUS ROG Strix X570-E Gaming with Ryzen 7 3700x

Hello @wedens, @RichGuk. I have released the new version, can you try it? Seems like zen2 ryzen CPUs are reporting soc/core values on swapped addresses so the new version is expeting that.

Also @wedens do you still have that X370 board? Can you post either HWinfo debug log or zenpower debug data (#12) ?

I don't have X370 board. I have B450 board. I think @RichGuk had X370.

I'll try the new version with my board soon and report back.

wedens commented 5 years ago

I can confirm that with the new version results look like what I'd expect.

UPD: were there any temperature related changes? it shows idle temps a fair bit higher then before

ocerman commented 5 years ago

@wedens No, there was no temperature-related changes in last version

This issue could be closed I guess.
