HWiNFO v6.27-4180 Beta available.
Fixed and improved monitoring of VR VCC sensor on Intel SVID VR systems.
Added per-rail voltage and power monitoring on NVIDIA GPUs.
Enhanced sensor monitoring on ASUS ROG STRIX B460 series.
Fixed a possible crash on some systems with down-cored CPUs...
VR VOUT on Z490 series is currently being worked on.
Your board doesn't feature a dedicated RAM temperature sensor and I doubt the BIOS is showing it either. So RAM temperature is available only for modules that feature a temperature sensor (TSOD).
I'm not sure. This would be usually a case when some other monitoring application is causing a conflict accessing the sensor. But if you're sure there's nothing else running...
A bad sensor would be quite unlikely, but I have no other ideas what could be causing this.
Can you please verify with some other tool if it shows such erratic values too? For example CPUID HWMonitor or something else that shows min/max values as that's the best way to catch such out of range values.
Thanks for the feedback. I'm interested in any details.
I'm working on this with GIGABYTE and yes, it should be accessible and registers still follow the PMBus specification. But apparently it uses a different protocol, but I'm not sure yet how different it is.
