Testing overclock on my 8350: wacky cpu temp diode

I am testing out my overclock on my 8350. So far I am at 4.3ghz @1.4v, but my temp diode is going wacky. My system is running Prime stable though. My question is, since I can't trust my cpu temp diode, what about my liquid temp sensor in the radiator? It currently reads my liquid at rough 40c. Any thoughts?
 


the mb socket temp is usually accurate within 5C or so (it's usually the first temp reported by the mb if it's not labeled), for example, on my mb it's within 2C of the reported core temp... remember, the liquid temp in the cooler, depending where the thermometer is located, won't be all that close to the actual cpu temp if your liquid loop is working properly.

This sounds more like a driver sensor signal error. What are you using to read temps? Using more than one prog?

What board is this too please? There are 2 sensors possible involved. Socket or internal chip. Both send signal to a super I/o chip. Most commonly Nuvoton chip.

MSI 970a-g46 motherboard. I am using Core Temp and HW Monitor. Both are reporting the wacky temps. For the liquid temp, I am using Chill Control V (came with my Asetek AMD FX liquid cooler). Still stable; tested last night with a few hours of playing BF3.

Never use multiple monitoring programs at the same time - it can cause issues like this as the .dll and driver data gets corrupted.

Uninstall both, reinstall, use only one at a time. I have seen this issue cause registry corruption bad enough that full windows reinstall was needed

Oh I didn't mean I use HW Monitor and Cor Temp at the same time. Just that I have used both for testing. What I do run together is Core Temp and Chill Control. The Chill Control app is what ramps up my fan speed as the liquid heats up. Would these two programs be conflicting?

Absolutely. They are using the same data to perform their separate tasks. Consider a digital fan controller in stand alone? Full boat ones can be around 50-60usd. You can go relatively cheap with massive performance with a Poweradjust2 Ultra - lil pcb that can function as standalone temp controlled fan controller) or Aquareo 5 LT (the base version) which handles 4 channels, and the Poweradjust2 works with it for up to 10 channel control over USB software. That is the high end of control granted

I was under the assumption that there was a separate sensor inside my radiator/water pump that reads out my liquid temp in Chill Control.

sorry I was under impression chill control also read CPU data and incorporated in software output.

Still, there are 2 possibilities:
1) registry data corrupt and causing misreads
2) variations actually occurring at rapid level causing misread, which indicates, thermal throttling via voltage

#1 seems more likely to me, being that you don't see it in BIOS. When reading chip info in bios, all power saving features are non functioning and chip is going 100%. So very pure data.

If the Core Temp program is reading way off temps at a certain point then, does that mean the PC starts throttling itself?

Here's a question for you. I have noticed that whenever I read a guide or look up others experience with overclocking AMD chips, they say to disable Cool N Quiet. Is this simply for stability purposes or some other reason? I have it enabled currently without issue.
