"Core Temp" - A program for accurate Conroe, Merom and Yonah temperature monitoring

[The Coolest]

Download Core Temp v1.0 RC1 (http://www.alcpu.com/CoreTemp/)

This program that lets you monitor Intel's Core 2 and Core i3\i5\i7, AMD Athlon64 and later VIA C7 and Nano chips' die temperature.
The temperature readings are very accurate as the data is collected from a Digital Thermal Sensor (or DTS) which is located in each individual processing core, near the hottest part.
For more information click here (http://www.alcpu.com/CoreTemp/howitworks.html)

There is also an article posted about Core Temp and a little background on standard thermal sensors - Article (http://www.overclockers.com/articles1378)
Please help out Core Temp popularity by Digging (http://digg.com/hardware/Dual_Core_CPU_Temps_a_program_to_monitor_EACH_core ) it.

You gotta be kiddin me... WHERE YOU BEEN! EEEEEEEEEEEEEEEERBODY here knows about Coretemp! I thought you were "The Coolest"! You supposed to know what's going down! Now how are we gone hit all the late night underground parties in Bangkock if you don't have none of the info?

My name is Arthur Liberman, so if you read the About box that would ring a bell ;)

This is a new version, check it out

hey thanks Coolest. :D

remind me again what "Tjunction" is?

[The Coolest]

The junction temperature between die and PCB, IIRC.

[dogbert_2001]

How is this a new version? July 10th?

Edit: NM, your post is just wrong. Website says Oct 19.

LOL, that was a nice typo :D thanks for pointing that out

[telexen]

I've never been able to get this to open on my dual opteron system. I open it and nothing ever happens...seems to crash before anything can come up. Although it does show an icon in the systray that disappears once I mouse over it (because it's not running anymore)

[surjer]

Anyone know why this program reports different temps than TAT? These are supposedly the 2 most accurrate programs out there for C2D but they are still in fact different...

well then the prog isn't reading it correctly i guess, because mine is ALWAYS 85c. or is that the way its supposed to be?

It reads temperatures just fine with my e6300.

My guess it's your motherboard. Flash to the newest BIOS?

[imposter]

great program using it on my c2d as you already know =)

[brywalker]

I thought that it was the max the CPU could handle.

I really hate the 1 - 2 degree delta between the cores. Bad design, me thinks.

[benbaked]

Does Core Temp show Presler core temps?

[The Coolest]

Does Core Temp show Presler core temps?
No, this feature is not supported in Presler or older, they implemented it first in the Core Duo/Solor (Yonah) and continued with Core 2 Duo (Conroe).

I thought that it was the max the CPU could handle.

I really hate the 1 - 2 degree delta between the cores. Bad design, me thinks.

Actually a Delta of 1-2 degrees is very good.

[dominick32]

Thanks for the update. Any chance you can modify code to allow Live vcore monitoring and updates along with the temperature? CoreTemp seems to simply pull the bios vcore and keep it as a static number.

Thanks for the great software.

VID != VCore. VID is voltage ID, its what the motherboard uses to set proper CPU voltage. This value is variable in laptops and in PCs running with EIST enabled.
Unfortunatly there's no way to read actual VCore from the CPU, and I don't see that changing anytime soon.

its showing my temps just fine as well, i'm talking about the Tjunction....does yours change? and yes my bios is up to date. ;)

Tjunction is a static value (similar to TCaseMax) only it relates to the maximum temperature "allowed" for the junction between the CPU die and the PCB.
This value can be either 100C or 85C in Core/Core2 CPUs

I appreciate your feedback and I do know that VID is voltage ID and a static number. That is what I was pointing out. I am very curious if it would be possible for you to implement live voltage monitoring? Example: Is there any way to access the motherboard vcore monitor/sensor such as PC Probe does?

And I also see that you responded with: Unfortunatly there's no way to read actual VCore from the CPU, and I don't see that changing anytime soon.

So I guess not... Anyway, great software. :beer:

I would believe Core Temp\TAT reading quite a lot more than software that reads a sensor that is located on the motherboard.

[surjer]

n5bail:

I have been trying to find this out as well... Since they both are suppose to be reading from the built in chip sensor.

My guess is in the programming its not a simple call like "CPU.GETTEMP" but more like a sensor reading that has to be ran through an equation to determine the temp. I am betting that TAT uses a slightly different equation than Core Temp?

Maybe its a rounding issue? Floor vs Ceiling? Its gotta be in the coding if they are BOTH reading the same sensors???

[updawg]

coretemp reads the temperature of the core (tjunction) and your speedfan is reading the temp of tcase. You can also see that intels thermal analysis tool is close to coretemp, they are both pretty acurate.

the other version was off for Allendales by 10c-15c so yes that is the right temp with the new version.

yea your temps are fine...well im using a ninja hs and was seeing temps around 50c with .94 so i would assume around 60-65c with the temp correction, TAT never has worked for my mobo so i dunno about that one.

Just downloaded the latest version for my newest acquisition, an E1705 laptop. .94 wasn't reading the temp correctly and was significantly different from tat. Now both read in the same range, so .95 must have fixed whatever problem .94 had with this system. Thanks for the proggie, T_C. :thup:

so if you have a quad, you look at core # 1,2,3,4 and you want all of those temps under 70 degrees or so? or do you look at the Tjunction temp??

[Evilsizer]

so if you have a quad, you look at core # 1,2,3,4 and you want all of those temps under 70 degrees or so? or do you look at the Tjunction temp??

tjunction is the max temp for the die, you want a 20c buffer to the tjuction number.

[w00tstock]

So just to make sure im not an idiot, if im getting temps of
"73C* to Tjunction max remaining" it is safe, till I get to about 20C* remaining?

[aoch88]

I don't think it's showing the right temps for my E2140 M0. In previous 0.95.4, I get 29C idle and 60C load but with this new version, I'm getting 45C idle and 75C load. Doesn't make a lot of sense?!

[w00tstock]

That could be corect aoch88, i belive from reding up on this that there weas a bug/error in the reading of the tjunction max, resulting in a 15C* lower temp.

[aoch88]

Yup, I notice the Tjunction has been changed from 85C to 100C in the new version. We're talking about 75-77C full load. Is that for real?!

Btw, I'm on IFX-14 and it looks like temps are terrible high :(

[The Coolest]

I think it may be wrong, it will be back to normal in the next release.

[aoch88]

I think it may be wrong, it will be back to normal in the next release.

I think so too as the difference between BIOS idle temps and Core temp is like 10C+ :eek:

[hokiealumnus]

TheCoolest, are you saying you believe the M0 chips are actually an 85c TjunctionMax? I think they are 100c and posted in another thread on the subject. It doesn't affect me as I don't have an M0 chip, but just out of curiosity, I'd love to know the outcome of this interesting issue. Anyway, here's the post:

Just playing the devil's advocate, have a look at the Intel specs:

E4400 L2 Stepping (http://processorfinder.intel.com/details.aspx?sSpec=SLA3F) & E4400 M0 Stepping (http://processorfinder.intel.com/details.aspx?sSpec=SLA98)

The thermal specs are 61.4c for the L2 & 73.3c for the M0. AFAIK, they didn't change how they came up with the thermal spec (very simplified, an external temperature probe on the IHS). How could the TjunctionMax go DOWN while the thermal spec went UP?

That's what is leading me to believe that they still have a 100c TjunctionMax. Now, whether 15c needs to be added to CoreTemp (and every other temp monitoring prog in existence apparently) is a question I can't answer.

Could it be that the TjunctionMax is just being reported incorrectly but the temperatures are correct? This is definitely a strange issue.

I don't follow.
Core Temp supports all Intel CPUs.
Tj.Max is adjustible by users if they chose to.

Version 0.98.1 (http://www.alcpu.com/CoreTemp) - 23rd April, 2008

- Fix: Incorrect recognition of 45nm Intel CPUs in version 0.98.

[martymonster]

I run Windows Ultimate 64 bit version with a Q6600 G0 running at 3.3GHz.
With v0.97 of coretemp, I found that it would run as long as the system was not busy.
Whenever I started Prime64, Coretemp would crash after a min or so.
I am trying the latest version now.
So far after 15 minutes coretemp has not crashed.

With regard to temp readings.
I went thru the complete calibration process I found in the stickies using speedfan.
When I now run Coretemp and compare the readings with my calibrated speedfan, they are so close as to be the same ( coretemp is approx 0.5 - 1 Degree Celsius lower).
Realtemp gives a 5C lower reading than Coretemp as it uses a TjMax of 95 compared to 100 in Coretemp.
I believe that the author of Realtemp is using flawed data to obtain his TjMax readings.
Using the thermometer to read the outside casing of the CPU is not the same as getting the readings from the diodes enclosed within the CPU housing. Who knows what temp difference there is between the outside of the case and inside the case.
Just my 2cents worth. :beer:

EDIT::: I found the cure. Seems its another Vista nag screen to find and disable. all is well now but the Core Temp icon has this shield on it indicating it needs admin premissions. WHAT A MESS.

[The Coolest]

Beta Version 0.99.0.8 (http://www.alcpu.com/CoreTemp) - 7th May, 2008

Changes from previous beta:

- Fix: System tray setting "Show highest temperature" only displays one temperature reading in multi CPU system.
- Fix: Mobile 45nm Intel CPUs should now be correctly recognized *hopes really hard* - needs testers
- Fix: Certain problems with font resizing should now be fixed.
- Fix: G15 LCD would not update after using soft buttons.
- Fix: On temperature display mode change, high and low records were not reset.

- Add: Support for Intel Core 2 Duo E7000 45nm series.

- Change: Improved detection of L2 cache on Intel chips for accurate recognition.
- Change: Rewritten temperature calculation to fix problems with shared memory. Needs more testing to confirm as 100% working. (Play with temperature modes... Fahrenheit, Delta to TjMax)

Please help me out test this beta, see if you can dig up more bugs that need to be fixed.

Z


EDIT::: I found the cure. Seems its another Vista nag screen to find and disable. all is well now but the Core Temp icon has this shield on it indicating it needs admin premissions. WHAT A MESS.

As Core Temp has to load a driver when it runs, a user must have administrator privileges.
I'd also like to know how do you disable that nag screen that asks you to always allow Core Temp when you run it.

[Zuzzz]

In Vista hit Start then Search. (LOL I did say search) and type "security" There you will see 2 sets of features in the RIGHT panel. Select "Local Security Policy". You will then choose "Local Policies" on the right panel of the next screen. Next pick "Security Options" also in the right panel. Now scroll all the way to the bottom. There are about 9 "User Account Control" options. The one lableled "User Account Control: Behavior of the elevation prompt for administrators in Admin Approval Mode". There will be a drop down menu with 3 options. Select "Elevate without prompting". You may get nag screens from the UAC while doing this. Once done you should now be able to run Core Temp without getting the darkened screen with the UAC asking if you reallllly want to run this. You WILL still see the security shield on the icon if you created a shortcut however CoreTemp WILL run without being prompted by the UAC. I hope this helped and was what you wanted to know.

Z

I have found that Some Vista Home users may not see the option "Local Security Policy". This fix for this is to edit the registery to do the same thing.

Press the Windows key, type regedit and press Enter. Browse down to this registry key:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Policies\System]
2. You should see a key called PromptOnSecureDesktop. Double-click this and change the value to 0 (zero)

Lets Microsoft Perfomance Monitor to do the charting & logging stuff, but make the coretemp capable of running as a service instead of a program, so it can be really handy for logging and other triggered events in various automation in handling cpu temperature related issue.

I'm not sure if this is what you're getting at, but some way of logging temperatures and vcore etc. to disk would be really useful for diagnosing crashes. The only problem is that you need to have logged the details soon before you crash, which means you'd have to write to disk pretty frequently. Does that make sense?

[The Coolest]

I'm not quite sure what is the problem, but Core Temp has logging to a file right already...

This is a little add on for Core Temp. Currently it's in public beta phase, not ready as final, but ready enough for public testing.
Simply extract both files in the ZIP, run the exe. Core Temp 0.99 must be running for it to work.
A 3rd file "Grapher.ini" is created with defaults. You can edit that file and restart to program to apply changes. (You can also click the Actions --> Reload colors to update the colors on the fly from the ini file, without the need to restart the app).
All settings are pretty straight forward. A later version will include a GUI for the settings.

Oh!
A register dump file + a screenshot at idle and full load would be great!
If you have an IM that'd be even more awesome :)

Regarding the E7200, Core Temp wasn't reading the 45nm voltage correctly untill 0.99 :) The fix is mentioned in the change log.

I'm very new at monitoring hardware and came across this nice program to check the temperature on my CPU.

How do I know if my laptop's CPU is running at an optimum temperature?

CPUID = 0x6E8
APICID = 0
Revision = C0
Processor = Intel Core Duo ULV L2400 (Yonah DC)
Frequency = 1064.00MHz (133.00 x 8.0)
Platform = Socket 479
VID = 0.9750v

Tj. Max = 100 C
Core 0 = 67 C 11%load
Core 1 65 C 9%load

Thanks in advance.

I'm starting to build a plugin engine for Core Temp.
Besides shared memory, which allows developers to create their own standalone applications, plugin capability in Core Temp would mean that a user can install plugins into Core Temp to add new features and functionality.
As the most simple example, "Core Temp Grapher" (http://www.alcpu.com/forums/viewtopic.php?t=429) will be converted into a plugin, meaning users will be able to have it as an integral part of Core Temp without the need of running an extra standalone program.

Plugins are very useful in that anyone can easily extend the usability or functionality of an application, as the interface to the host is usually an open standard.
This also makes the application modular, meaning that replacing or updating code will be as easy as replacing a DLL file in a directory.
I'm really excited about this and hope I can make this happen soon.

What do you guys think?

I'd really like some feedback. I think people with some developer's knowledge would probably see why this is a great addition. Extending functionality without actually touching a single line of code in the main executable.

And to other news... :p
A new version - 0.99.1 will soon hit public beta.
It adds support for new CPUs like Nehalem, Atom, the new 45W AMD K8s.
There are a few bug fixes and some new features and changes, mostly GUI related.
All the settings were finally moved to the ini file. The only thing that remains in the registry is the option to start Core Temp with windows. (no way around that)

To make Core Temp run on Linux I will have to rewrite Core Temp from scratch.
Unfortunately, I don't see that happening any time soon.

load at 80? my laptop idles at 81 and loads at about 100c. shockingly high i agree, but ehh.

thats a good idea, then you could have a host program that just monitors those reported temps and graphs the data, plus give you alerts if they get hot. I would use that at work to monitor the server temperatures.

[AusDog]

Glad to try another. RivaTuner and RealTemp disagree by 6-7 degrees C.

[EarthDog]

They disagree likely b/c the tjmax is set different. Coretemp and Realtemp have it right. ;)

Version 0.99.5.27 - 5th August, 2009

- Fix: Crash on AMD 45nm processors.

[Bobnova]

- Change: TjMax for mobile Atom processors changed to 90C.

That's a big change from 125*c! Makes me feel better about the temps reported though, as that'd mean the atom in my netbook is really running at 40*c, not 75!

How'd you find out what the TjMax was?

[just dan]

just found this and put it on me laptop, i gots 34 idle and 59 load :D

[The Coolest]

How'd you find out what the TjMax was?
It's not 100% accurate, since some chips are probably still 125C, I just had a lot more input from people reporting major over reporting when 125C was set.

[Packrat]

I use Coretemp, it's been great. A question and a feature request: I have Coretemp set to start automatically, minimized to the tray, so that the desktop gadget (in Windows 7) works at bootup without having to manually start coretemp. This doesn't work, it doesn't open automatically.

About the same desktop gadget, is it possible to change the number of cores it displays? I've got 8 cores, but the widget only displays four.

Apart from that, very useful program! I recommend it to anyone who needs such a thing.

[dudleycpa]

Did you put it in the Startup folder?

[Packrat]

Did you put it in the Startup folder?

No, I used the built-in auto-start functionality. It probably puts a reference to it in the run key in the registry.

[Bobnova]

So i finally got this latest version, and there is no way that the new Atom tjunction is correct, at least not on mine.
In 80*f ambients it has the core sitting at 8*c. Previous has it at 44ish, which seems much more reasonable.

[The Coolest]

Hi everybody!

I know an update is long overdue but real life kind of got in the way. With college, work and other related projects taking up the majority of my time I simply didn't have much or any time to work on Core Temp.
Anyway, the new version is now up on the main Core Temp page here:
http://www.alcpu.com/CoreTemp/

You'll notice that there are not many changes, mostly bug fixes and other small improvements.
Core Temp is now built on Visual C++ 2010, which means that the oldest supported operating system is Windows XP SP2, which I think should not be a problem.

Of course all new and some of the upcoming processors are now supported. For the Intel camp, in theory newer processors should not need Core Temp to be updated to be able to report accurate temperatures anymore (even if it doesn't recognize the processor itself).

One other major difference, and this goes to the Intel guys, is a totally new algorithm for clock speed detection.
The first and biggest change is that the new algorithm is now monitoring on a per-thread scale. This means the main window will display the highest processor speed out of all the running threads, and in System Information window you will be able to see the frequency of every single thread. (I'm saying "thread" because in the HT enabled Core i7 processors the frequency reported by each thread of a single core could differ).
It measures the frequency every 50ms and displays an average frequency over the span of 1 second. This should allow for more stable and accurate clock speed.
:)

Amazing OC for that chip Sam :thup:

[The Coolest]

Version 0.99.8.0 (http://www.alcpu.com/CoreTemp) - 3rd October, 2010

- New: Completely new settings dialog, much clearer and easier to use.
- New: Added Hibernation to Overheat protection options.

- Fix: Mobile Intel Core2 Quad processor recognition issues.
- Fix: Pentium Dual-Core E6000 series model detection was incorrect.

- Update: TjMax adjusted to 100c (Intel's specs) for 400 and 500 series Atom processors.

[Bobnova]

I fired the previous version up on my n270 atom, and it puts tjmax at 90*c which gives readings well under ambient temps. Whether it's more accurate then the prior tjmax of 125*c or not i don't know.

[The Coolest]

Hard to say, Atoms are tricky. Intel's specs say 90c for the N200 series last I checked, but in some processors that figure just didn't make any sense as the temps were heavily under reported. At 125c TjMax (just an approximation) the temps were starting to make more sense.

At this point, what's supposed to happen is:
For the N200 series Core Temp uses 90C TjMax while for the desktop CPU's it uses 125c.
In the new N and D series, the TjMax was updated to 100C for both of them.

[logicalsam]

i think we have another bug...i'm using an asus lancaster8 mobo with the e2140 cpu...says my idle temp is 17c and 19c in a 18c room...oced 1344.5mhz-1790mhz via intel speed step.. but at full load it is reading 60c after about a half an hour...isnt this a huge jump....correct me if i am wrong...but @14c room temp its reading only 16c and 18c idle and 59c and 60c under load...

[The Coolest]

I wouldn't count that as a bug. The further the sensors are from their calibration point, the wider their margin of error gets. Meaning that 17c idle in a 18c room is obviously a wrong reading. This doesn't mean that the chip isn't around 20-22c at idle.
The jump is pretty high but not unheard of. It really depends on the load and on the cooling that you are using.

[logicalsam]

using the stock e2140 heatsink/cooler...which i'm pretty sure cant keep it below the room temp....and i find it hard to believe it is even keeping the cpu at room temp even idle..what realy has me bugged out tho besides that is the extreme change in temp with only a 445.5mhz difference in clock speed..disabling intel speedstep which is a pain with my config...locks it in at 1344.5mhz 100% load under prime95 its only reporting 37c which is a big difference for only a 445.5mhz jump..i like your program its easy to use i would just like to see a bit more accurate temp reading cause i dont know what to believe here and i dont like letting my main components get over 65c max...if i remove the overclock and set it back to stock speed 1602.4mhz it reads a max load temp of 49c with the same ambient room temp...not downing you by any means i keep hearing good things about coretemp just would like to figure out what the temps realy are...

[The Coolest]

It's all in the voltage. The more voltages has a much bigger effect on temps than frequency.

[The Coolest]

Hey guys...
I know it took forever, but Core Temp version 1.0 (RC1) is here at last!
There were many delays due to life, college projects and other things that just got in the way.
I hope that the improvements and enhancements which v1.0 brings will make up for it.
So without further ado here is the change log for the new version.

Version 1.0 RC1 (http://www.alcpu.com/CoreTemp) - 18th August, 2011

*** Core Temp Monitor is now available, an Android app to monitor your machines from anywhere in the world!
More information is available here (http://www.alcpu.com/forums/viewtopic.php?t=1945)

- New: Multilingual interface. Core Temp now natively supports adding non-English languages.
- New: Plugin system - 3rd party developers can now create plugins and extensions for Core Temp, both native code and .Net is supported, please see this (http://www.alcpu.com/CoreTemp/developers.html) for more information.
- New: Intel Sandy Bridge and AMD Fusion (Brazos, Llano) support.
- New: Max TDP detection on supporting processors.
- New: Power consumption on Intel's Nehalem and newer processors.
- New: Added support for VIA processors. (C3 - detection only, Temperature by Acpi Thermalzones)
- New: Added support for Intel Pentium and AMD K5 and newer processors. (detection only, Temperature by Acpi Thermalzones)

- Fix: All of the user reported bugs and many more unreported problems.

- Update: Optimized the startup code, Core Temp should now launch 2 to 4 times faster.
- Update: Optimized many other aspects of the code, Core Temp should now consume much less CPU time than before.
- Update: Restored support for older OS: Windows XP is now fully supported, Windows 2000 requires security updates KB935839, KB835732 and GDI+. In some cases hotfix KB816542 may be needed as well.

[EarthDog]

Awesome! Thanks for the headsup!

[mbentley]

I'm confused. I didn't see anything about pie charts in your new features :p

I'll have to give it a try a bit later.

[seth.i.simmons]

Working awesome so far, loving the instant startup! MUCH faster. And the decreased CPU time is nice. Awesome work, The Coolest!

Edit: After using it extensively today, I love that it finally show's the actual max CPU speed (4.5Ghz for me right now, where 0.99.8 only showed 3.3Ghz no matter what, and I like that it shows power in watts. Only problem is, it seems to be throwing impossible numbers up for max CPU temps reached, and power. It's showing that all my cores have reached 98C, which they definitely HAVE NOT, and the power spikes to over 2000W (2436W at one time) every once in a while :P Other than that though, great work. Attached is a screenshot showing the 98C max reached.

[The Coolest]

It is a bug. I'm working on fixing it, and some other minor bugs.
When it's ready, another version will be released.
