ASRock Z490 Taichi - ISL69269 readings incorrect

[Lukas0610]

Hey,

I recently noticed that the VRM sensor readings of the ISL69269 on my board are finally showing up, but, as the title says, are of no use.

I attached the debug file and to screenshots to show what's going on.

Thanks in advance

Are you perhaps running some other monitoring tool (i.e. ASRock A-Tuning or Motherboard Utility) along with HWiNFO?

 

[Lukas0610]

No, no monitoring tools running besides HWiNFO, I also already tried closing every running program possible (and restarting HWiNFO afterwards), didn't fix the readings.

Please try this build and let me know how it works: www.hwinfo.com/beta/hwi64_641_4336.zip

Now the ISL69269 isn't showing up at all, just on first start of your provided version it showed up twice, but the values were still incorrect.

 

[Martin]

Thanks. Can you please try to reboot the machine and then run in Sensor-only mode?

 

[Martin]

And here one more build to test: www.hwinfo.com/beta/hwi64_641_4337.zip

After a reboot both ISL69269 show up again, only to disappear on every startup afterwards, plus I noticed the sensor detection takes a few moments longer than on the first startup after the reboot.

 

[Lukas0610]

Here are both debug logs (with and without the ISL69269 showing up) with the new version you just sent.

 

[Martin]

Thanks. Please try this one: www.hwinfo.com/beta/hwi64_641_4338.zip

Works far better now, the values seem good (although they don't really add up, but I assume it's how the sensor reports it), don't need to reboot anymore, only that it says ISL69138 now and there's a second VRM with only temperatures and input voltage showing.

 

[Martin]

Thanks! Looks good to me and it's indeed ISL69138.

Interesting, every board review says its using an ISL69269, like here on AnandTech (https://www.anandtech.com/show/15781/the-asrock-z490-taichi-motherboard-review/9) and TechPowerUp (https://www.techpowerup.com/review/asrock-z490-taichi/4.html)

Not that I care much about these small details, just find it interesting.

 

[Martin]

Well, yes it could be a 269. However proper identification requires a certain function, which doesn't work in this case. I'll look into this a bit more.
