Hi, I'm another owner of a motherboard with a stuck sensor

I will not write the details, as everything has already been described on this forum and Reddit:

System:
MSI X870E TOMAHAWK WIFI
AMD 9950x3D
Arctic Liquid Freezer III 420
PCCooler YS1200
GeForce RTX 5070 Ti

If you have solved the problem with the sensor, please share the solution in this topic

25 mins and still okay for me. Hopefully it stays this way lol. What BIOS are you using?

I hope it doesn't happen again but to note... I went down to 7E51v1A1A and used Gen 4 as apparently there was issues with Gen 5 on the newer BIOS versions.

Try this one and do them settings I included above 7E59v2A90. "set memory context restore to enabled, expo, pcie gen 4, integrated graphics disabled."

If you test and it's still no good, go on the "memory try it" and try going from 6000mhz to 5600mhz or keep it at 6000mhz but increase the cas latency to like CL38 or something.

I tried these settings, but nothing new

If I use curve optimizer to undervolt and go above -20 I get 0w package loss but if it's -20 or normal it works okay with all the settings I have above but yours is the the "e" variant.

If it happens anymore, i'm going to reseat the cpu and reattach the fan because I was struggling to mount the Noctua fan and kept having to lift it up and it was hard because the paste was glued to it, so maybe it slightly raised the cpu in the process or something.

Regardless, it's working great so far but i'll keep updating and if the problem persists i'll try other things.
