VR-Loop 1 & 2 drops down to 0 degrees

[oopps24]

Hello Guys,

i have a Gigabyte Z590 Master BIOS F7 with Intel i9-11900k.
After a few times, i see a 1 second drop on vr-loop 1 and 2 to 0 degrees. Is that normal?
After that HWInfo64 can not read more the DRAM Temp. It's marking grey. If i restart hwinfo. DRAM not more detected. I need to restart PC, before HWInfo detected DRAM. Is there a bug or a hardware problem?
Thx for help.

That looks like a failure of the entire SMBus. If the issue happens are all other VR values 0 or gray, not just the temperature?
Are you perhaps running some other monitoring or tweaking tools with HWiNFO?

Hey thx. No only VR-Loop1 and 2 displayed 0 degrees for a second. After than is displayed normal, but DRAM is disabled and marking grey. CPU displayed sometimes 0 degrees too, but i fixed it with disable c-state in bios. PC works normal. No other issue, no crashes or whatever in or out of games.
Yeah i using Winaero Tweaker, Classic Shell, RGB Fusion to control RGB and Aorus Engine thats a tool for the graphic card to control fan speed and oc or silent fan mode. I think RGB Fusion makes that problem. but i can not say it. I hope its not a hardware problem.

I it's the RGB Fusion causing that issue as it conflicts with any other tool accessing the DIMMs or sensors. Has been observed and reported multiple times.

Ok, thx for ur help. Is it a issue for the system or only read wrong temp of DRAM?

A software problem of RGB Fusion.
