Odd temperatures

[KingofFah]

All right, I am just going to post this to get some opinions.

I assume the board I have has a messed up sensor; it reads as 46C at post for my 165 opty.
It sometimes randomly goes down to 38C or up a little from the POST to 51 52.

Using Core Temp, I see that my cores are at 31/31C at idle.

Looking in Speedfan, I see "Core" reading about the same. With temp1 at 54 right now (this corresponds to none of the temps even in the motherboard), and temp1 just flies all over the place while idling (between 40 and 60c).

I reseated the HSF just to be sure, and I haven't had any problems thusfar.

While priming, the core temps are 51C (remember, the core temps), so I assume the motherboard diode is just way way off. I assume it's probably at most low 40's.

But LMK your thoughts.

Motherboard: Epox 9U1697 GLi
CPU: opteron 165 (CCBWE TMPW0604 -- not the greatest stepping in the world)
HSF: Gigabyte G-Power w/AS3

How sure are you that it isn't reading your capacitor temps? Anyway, your diode temp is supposed to be Temp 1, in SpeedFan.

Well, what I am saying is that the diode temp must have problems. It corresponds to the "CPU TEMP" LED on the mobo. The temp is higher than the core temps (a lot higher), so I cannot see how this could be correct (since the cores should be much higher than the diode sensors.

Please clarify:

How sure are you that it isn't reading your capacitor temps?

Do you mean the core temps or the diode temp on the mobo?

 

[myocardia]

Sorry, I forgot about you. Okay, it's completely normal for the core temp to be below the diode temp, while the cpu is idling. In reality, it isn't below, but this is software, and it isn't exact. Anyway, if the core temp is below the diode temp while stressing the processor, then you just have a bad sensor (the diode).

And, what I mean is which temp are you reading? With SpeedFan, there's only one that corresponds to the cpu diode: Temp 1. The chipset can either be Temp 2 or Temp 3, but never is the processor any other Temp than #1. I was just making sure that you realized that, that's all.

There's core and there's Temp1. Are these not two different temperates? Or are they both supposed to be the same? It sounds as if your confusing what I am talking about.

Just to clarify, "Core Temp" is another program. The "Core" temperature reading in Speedfan says roughly the same thing as the "Core 1" and "Core 2" readings in the "Core Temp" program.

I was never trying to communicate that I was not sure what "Temp1" was reading, but I was only trying to say that it seems to be way off and possibly bad. The "Temp1" reading in Speedfan is all over the place during idle, and much hotter than the core temps during priming.

lol, and yes, the whole purpose was for someone to just confirm my thinking that the sensor is bad.

Shouldn't the core temps be hotter than the diode at all times? But at least at load, I would assume, and they are not.

Which one is more accurate/representative of the cpu temperature between temp 1 and core? Core seems to fluctuate a lot (every 2-3 seconds) while load remains at 100% (crunching SETI). It can be from 2C to 7C (generally 2-3C) higher than temp1. I know it's supposed to read the K8 core sensor. Temp 1 fluctuates very little, mostly following room temperature and matches PC Probe 2 and bios readings.

(Just upgraded from Speedfan 4.28 to 4.30. Core temp was not in 4.28.)

lol, dennilfloss, that is what I am trying to determine. Temp1 is flying all over the place during idle. I cannot believe that the cpu temperature would go from 38 to 50+ and back and forth while idling. The core temps show a normal 31-32 and fluctuate frequently. Under load, they go up to somewhere between 45-50c, which seems normal for the core temps. So I doubt that the cpu sensor is working properly if it always is higher than core no matter what and always flying all over the place (never stable temperature).

I've just decided to ignore that temperature readout.

My core has spiked to 58C but my apartment is very warm and CPU voltage is 1.41-1.42v. When I turn the AC on (most of the time), core temp averages 52-53C and temp1 averages 49-50C. Temp1 seems to be diode temp for my mainboard.
