"Core Temp" - A program for accurate K8 temperature monitoring

[The Coolest]

I set coretemp to load in startup...after getting into windows, low temp values do not appear (shows 0 deg ) at all unless i reset high/low. Normally lowest temps should be the ones first recorded after startup, correct ?

Not sure why that happens.
What CPU is it?

And on another note here are a few new things I'm working on:
Mini mode:


Proper overheat protection:


Per core offset adjustment:

Change log since the previous beta:

Version 0.99.5 (Build 6) - 7th February, 2009

- Add: Thermal protection mechanism. (Look at Options menu)
- Add: Mini mode for GUI. (Double click anywhere to switch between modes)
- Add: Per core temperature offset adjustment. (Look at Options menu)
- Add: Screenshots are now taken in the lossless but very compact PNG format.
- Add: User defined text colors for main Window. (Options --> Settings)

- Fix: PROCHOT signal from Intel CPUs was not picked up correctly.
- Fix: Core Temp would start out of the desktop area, and the main Window couldn't be seen/accessed.
- Fix: AMD K8 series incorrectly reports temperature at over 200C (CPU bug, workaround applied).
- Fix: High/low temperatures would be reversed when "Show distance to TjMax" was enabled.
- Fix: Clicking "Defaults" button in settings would enable logging when it should be disabled by default.
- Fix: "Show highest temp of each CPU" systemtray icon configuration sometimes reports duplicate readings.

- Change: Completely dropped support for older Windows NT OS, Windows XP or up is required.

Hi,

this great little program compelled me to register to report a bug I find anonying. please bear with me...

when I run with CNQ on in Vista, CoreTemp frequency detection gets all messed up...


this is the frequency the program shows for all 4 cores when it is suppose to be at "800MHz (199.99 x 4.0) (verified by CPU-Z) and not the above "2999.9MHz (749.98 x 4.0)."

Sequence that reproduces the wrong frequency reporting:

1) run with CNQ disabled. frequency reporting is fine.
2) run with CNQ enabled. program detects CNQ is enabled and changes to correct frequency at lowest power state (800MHz).
3) pressing the builtin refresh functions messes up the frequency detection to what is pictured above. Subsequent refreshes doesn't remedy the problem.
4) disable CNQ and now the program displays "11249.65 (749.98 x 15.0)." Enable CNQ and it goes back to displaying what is pictured above. Refreshing when CNQ is disabled will correct the problem and will display "2999.90MHz (199.99 x 15.0)."



my system:

Vista with latest updates
Phenom II X4 940
Foxconn A79A-S with latest BIOS
CoreTemp 0.99.3, CoreTemp 0.99.4 beta build 75 & CoreTemp 0.99.5 beta build 6

[The Coolest]

Yes, this is a known issue.
I'm actually trying to figure out a way to fix this. Hopefully soon.

^ Thanks again for your continued effort in making your great app available

[The Coolest]

Could anyone please confirm the new build from here works on their Phenom?

[-= rtz =-]

In previous versions up to 0.99.5 build 6 I was able to start the app but the frequency was incorrectly detected. (AMD X2 Brisbane BE) But now with the latest build 11 I can't even start the app, it shows an error message which I attached here. 64bit version, OS is vista x64 ultimate SP2 v113.

Yes, it's due to this:

This version is still "warm" from the compiler. The drivers it comes with are NOT digitally signed (as they are not finalized yet), so Windows Vista and 7 64bit users will have to reboot and Disable driver digital signature enforcement by pressing F8 at startup.

I just want to make sure everything works properly before I go and ask for the driver to be signed, this is why I've uploaded it this way.

[largon]

Works fine with Phenom II X3 720BE on Win7 64bit.
=)

Now, if AMD just fixed Deneb's temp sensor. The offset to software reading is clearly more than 10°C based on my measuments with a k-type sensor on a DMM.
*shakes fist at AMD*

edit:
Looks like the label "Freq. #2:" for X3's core#2 is missing:


edit2:
"Freq. #2:" does appear when in minimized mode:

[The Coolest]

Could you please press F3 (system information) and post a screenshot? I haven't had a chance to test it on a Phenom yet.

[largon]

Note the edit in my previous post...

[largon]

Actually, the label "Freq. #2:" is where it's supposed to be when the app launches, but it disappears if I double-click-minimize the app and then return to the normal view.

[The Coolest]

Thanks largon. I tracked it down. Should be fixed in the following release.

[gOtVoltage]

Hey ,, nice work as always..

9950
When i press F3 it shows Default Frenqency is @2700mhz( its 2600mhz for 9950's)



Also the last Tag (Core #3) ,, must of ran off with Largons #2..




Temps read the same as 99.4 tested with DMM .. looks good with the Low / High Boxes now.. Adding the Overheat Protection mode and Double clik priceless..

[The Coolest]

The label problem is rather funny, but it'll be fixed in the next release.
The default frequency part is problematic. BE Phenoms don't have a maximum multiplier, so Core Temp currently uses the P0 state values..
I guess that it's not a good idea doing things this way. I'll try to search for an alternative.
Thanks

it's not working for me it's say it's stopped as soon I start it.

[Final8ty]

Same problem here.

Same problem here.

I just tried on Vista32bit,, NO GO


PHII 550 @ 4ghz

The previouse 99.5 beta (biuld20) what im using ATM .

[The Coolest]

Strange, seems like it crashes on some AMD systems.
Final8ty, does it crash on your P-II 955? Or do you have some other system that it doesn't work on?

[cpuz]

It works on Intel systems.

Only have this system.
The 99.5 beta (biuld20) is fine.

[hikaricloud]

Not working on my system either, 99.5.20 works fine (what I'm using now).

EDIT: was trying the 64-bit edition.
