HWmonitor only displaying 3 core temps and they look wrong

[Herkulese]

Motherboard: Gigabyte 970A-UD3
CPU: Phenom II X4 965
Ram: G.Skill Ares Orange 8GB (2x4GB) Kit
PSU: SeaSonic Gold+ 550 modular

I ran Prime95 over night, starting at 8:00 pm.
I had it set to small FFT's and Priority 10.

I also had HWMonitor open and displaying Core Temps, which after 30 minutes seemed to top out at approx. 51c-52c. This is normal top out on this system under Prime95

This morning at 8:00am (12 hours later) all seemed to be working fine, with all 4 workers testing away very happily.

HWMonitor, however, was only displaying 3 cores, and those temps looked wrong, and the were completely static.
0 - 31c
1 - 52c
2 - 51c

It turned out that HWMinitor was not running, so I shut everything down.

I then opened up HWMonitor to find that it was still showing only three core temps but they are not static.
0 - 30c
1 - 30c
2 - 41c

I checked Task Manager to verify all cores running, and they all 4 look fine.

What do you thing would account for only 3 cores showing up in HWMonitor?

I would start by re-installing HWMonitor software and check again..

I'm guessing either a mislabeling of the sensors by HWMonitor or a bug. Try using HWInfo64 and see if it reads correct. It is also a more comprehensive monitoring program.

I remove and reinstall HWMonitor as well as this other monitor.
Please note, however, that HWMonitor was showing all 4 cores, and all, at rest, at about 30C.

Now it only shoes the following:
TIMPIN0 = 31c
TIMPIN1 = 25c
TIMPIN2 = 42c

Only 3 cores and not very consistent like before.

I reimaged my system drive to an image that had no monitoring installed, ever so that there would be absolutely no chance of bleed thru from an earlier install.

I then reinstalled HWMonitor, and it is still showing only the three cores just as listed above.


I, then (just now) downloaded and installed Core Temp, and it shows all 4 cores, and all at idle, at 29c-30c, just like HWMonitor did originally.

Very strange, very strange indeed...................

Those are not core temps. The core temps will have the text label "Core #0", "Core #1" etc

So it is not showing cor temps at all then.
I wonder why?
Even after what I know to be a clean install into a clean image of my system.
I think I will download a fresh copy and try that.

I would suggest grabbing "real temp" if you're not sure about whether your temps are accurate - my experience has been that real temp is spot on. It collects data directly from CPU sensors, and I understand that not all utilities do that. Other software temps can report different things at times for whatever reason.

That is great advice, and I am happy to hear that "Real Temp" is an accurate monitor, as and I have already downloaded and installed Real Temp.

I like it a lot, and am currently using it to monitor a Prime95 test as I type this, on another pc of course.

Thanks, and I appreciate the suggestion, in the case that I didn't already know about it.

As I think about it, I might be using Core Temp. I can't exactly remember at this moment.

Thanks again,
Roger

OK, I have lowered the core voltage to 1.35, by setting a -.125 below 1.475, and have set the LLC to regular (Choices are Extreem, Regular, Auto)

I have performed several, approx 30 minute, runs of Prime 95 Small FFT's, and have been seeing the following results:

HWMonitor shows the core voltage at 1. 344 (with a max of 1.38) and temps peaking at 53c.
HWiNFO64 shows the core voltage at 1.475 (Still) and temp peaking at 52c (I belive that it is just returning the "Normal" core voltage, which is 1.475, but the temps tell a different story).

If Core Temp is reading correctly, the voltage is holding steady at 3.44, and peaking at 1.38 (Voltage set at 1.35) and the temps are peaking at 53 (They were peaking at 58c with cv of 1.475).

I think this is good, but am willing to consider other opinions.

Comment please..................

The Phenom II X4 965BE has only one thermocouple for the core, so you can't get separate temperature readings for the 4 cores. I believe that motherboard has a thermocouple in the socket and another on the chipset, so those are probably what is being reported by HWMonitor.

A couple of posts back I was corrected, and then realized that I was not looking down far enough in HWMonitor to find the Core Temps.

It actually does show separate temps for each of the 4 cores, and they very slightly over time, so they must be being read individually.

They aren't. AMD has no individual core temp sensors, which they have stated numerous times. AMD has also stated that idle/low temp readings are not accurate until 45C or higher.

The core temps varying slightly over time is fine, but at any given moment the temperature of each of the 4 cores should be (reported) as the same. If you are getting different temps for each core for a given point in time, then the temps aren't being read correctly (or bugged software, etc.).

Please forgive me for being unaware of the 1 vs 4 core temp sensor in AMD processors. I was only going by what I saw in HWMinitor, which has been recommended many times and in many places.

It must just have the place holders for the 4 cores, but then read the single temp sensor, and then populate all 4 places holders with that single piece of data. Maybe I am remembering wrong about the varying over time.

I tried Real Temp, and ran into some kind of problem. I will try again.

Any other recommendations for good CPU sencors?

Search this forum for AMD temperature. You will learn why you cannot get an accurate reading from an AMD CPU.

Will do, thanks.

But then, how do you monitor temps with an AMD CPU?

You don't.

 

[Herkulese]

You don't.

Then what about all the threads regarding Stress Testing, and monitoring voltage and temp?
