Vista Sidebar Gadget - 14th May, 2008

A first public release of a Vista sidebar gadget for Core Temp, be sure to check it out. Latest Core Temp build also adds an option in the system tray settings to only display the Core Temp logo in case you're using the gadget and don't see the point for two places displaying temps.

[The Coolest]

Version 0.99 - 18th May, 2008

- Fix: Incorrect recognition of 45nm Mobile Intel CPUs.
- Fix: CPU temperature not displayed in Core Temp window on Phenom CPUs (0.98 and 0.98.1).
- Fix: CPU load would sometimes display -1% load.
- Fix: AMD K8 would sometimes spike to 206C, the false reading is now ignored.
- Fix: AMD K8 sometimes constantly reads -49C.
- Fix: Core Temp does not show up automatically on G15 LCD with 2.02 driver.
- Fix: Shared memory structure was not properly filled on multiprocessor systems.
- Fix: System tray setting "Show highest temperature of each CPU" only displays one temperature reading in a multi CPU system.
- 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.
- Fix: Changing the reading interval in settings did not actually update, restart of Core Temp was needed to apply the change.
- Fix: Incorrect VID detection on 45nm desktop Intel parts.

- Add: Shared memory - developers now have access to Core Temp data.
- Add: Register dump to text file function.
- Add: Preliminary Atom (Silverthorne) support - Untested.
- Add: Support for Intel Core 2 Duo E7000 45nm series.
- Add: Option to show a single icon instead of temperature in the system tray.
- Add: Custom font and size for G15 LCD screen or simply use the built in compact font and layout. (via Settings.ini)

- Change: Improved detection of L2 cache on Intel chips for more accurate recognition.
- Change: Rewritten temperature calculation to fix problems with shared memory. Needs more testing to confirm as 100% working.
- Change: Default G15 LCD text layout and font changed.
- Change: Doesn't create a log file containing session start and end times if logging is disabled.
- Change: Settings.ini file is automatically created with default settings in case one doesn't already exist.

MircCoreTemp plug-in - 17th May, 2008

You need SystemInfo script and latest Beta Core Temp

[The Coolest]

This is currently in a very early development. I've been working on this for the last couple of days.
If anyone ever saw PerfMonitor by Franck (CPU-z), then the idea came from his work, and he has helped me out a bit on several points.

Anyway here are the screenshots:






The graph is resizable. I still need to work a little bit on the efficiency of this thing but it's looking good right now.
All colors are customizable:
Background
Text color
Graph color
Grid color
Frame color (yellow in the pics)
0° graph (not shown in the pics)
Title text (up to 30 chars)

Do let me know what you think.

Hi

It's a good improvement.

Great work as always....................THANKYOU

Could it be anyway possible to have a setting which would affect how the core temp shows the temperature, like average temp of last 2 seconds etc.

Something like:

[AVERAGETEMP]
UpdateInterval=250
AverageTime=3000

I think it is quite self-explanatory. Read temps 4 times per second, and take the average temperature from last 3 seconds. As I have said before, that even though CoreTemp is accurate at reading the sensors, sensors aren't so accurate for humans. This feature could somewhat compensate the sensor "inaccuracy".

Also, I'd love to see average temperature of the cores with one decimal accuracy!

Well, I think this could be done with external program aswell without big hassle, but I am qite sure I am not alone with these feature wishes so the best way could be having those in actual main program.

Grapher update

I think the graph is now as optimized as it'll ever be.
Public beta testing will soon begin.

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.

Please post all bugs, problems and suggestions in this thread.

I'll have to give this a try at some point here

- Fix: 3/4 temperatures logged for Phenom X3/X4 instead of 1.

Hello.I have a phenom.Just downloaded core temp but it shows only 1 core.

[The Coolest]

Phenoms only have a single thermal sensor.
And the previous version would record 3 or 4 temperatures (depending on the CPU) in the log file.

[DevilCry]

thnx

[Rattle]

newest coretemp reads EO e8600 TJ as 105, are these 105 are are they 95 liek the C0's

thanks coolest

[The Coolest]

We don't know what TjMax they really are yet, we should know this Thursday, though.

[Rattle]

any news on that TJ ??

cheers

[The Coolest]

Following Intel's presentation about the DTS at IDF yesterday, Core Temp has been updated.

Version 0.99.3 - 22th August, 2008

- Add: Correct TjMax values for 45nm Core 2 series, according to this document.

- Fix: When TjMax = 0 (undefined) "Delta to Tjunction" was not added to the temperature string.

[Praz]

Thank you.

Version 0.99.4 - 23rd January, 2009

Major changes:
Completely rewritten base code.
Core Temp is now available in both 32 and 64 bit versions.

- Add: CPU detection improved, efficiency improved, speed improved, clock speed detection improved.
- Add: Initial support for Core i5 (Lynnfield).
- Add: Automatically detect Core i7/i5 series TjMax.
- Add: Show real-time TDP of Core i7 processors (still needs work).
- Add: Alternative clock speed detection for Core 2, i7 and i5 series and up.
- Add: Support for all currently available and some future processor families. (Intel & AMD)
- Add: Temperature changes color when temperatures hit high levels to alert the user. (Orange = hot, Red = critical)
- Add: Show (!) besides the temperature of a core which hit critical temp as a notification of past overheating.
- Add: Invalid temperature values are followed by (?) for both Intel and AMD.
- Add: AMD AM2+ 65nm processors get a 21c offset to fix incorrect temperature reporting (info from AMD).
- Add: AMD Black Edition processors identified by "BE" suffix after PR rating.
- Add: Display time and date on G15 LCD.
- Add: Complete DPI awareness - Core Temp GUI now scales perfectly with any DPI setting.
- Add: Rewritten algorithm for "Register dump" function, works much faster and more accurate (no ghost devices).

- Add: Redesigned log file system:
1) Settings window allows to start logging when Core Temp starts.
Logging can be toggled on or off from the Options menu or simply by pressing F4.
2) Layout is completely changed. Now it's easy to create graphs and the output is more coherent and understandable.
3) CSV file format is preserved.
4) Each logging session creates a seperate log file named with time and date of session start.
5) Logging is now off by default.

- Add: Register dump provides much more information:
1) Supported instruction set.
2) Supported features.
3) Manufacturing node.
4) Default CPU speed, multiplier range and maximum VID.
5) Bus ratio multiplier.
6) Processor and OS thread counts.
7) Cache: Count and size.
8) Processor topology.
9) PCI register dump also lists device names when "PCIDEVS.TXT" file is added to Core Temp's directory.
Link (scroll down a little)
10) Better output layout, easier to read.

- Fix: Core Temp crashes on Intel multi-processor platforms with Socket #0 unpopulated.
- Fix: Countless minor bug fixes due to rewritten code base.
- Fix: System tray icons do not appear after explorer.exe crash/restart

- Change: Core Temp will now work with A0 and A1 revisions of 65nm Core 2 processors.
- Change: Core Temp will not work on some/all virtual machine software.
- Change: TjMax values for 65nm Core 2 series adjusted.

Hi...thank you for the update...

Ahtlon X2 4850e Brisbane Rev.G2 shows correct temperature now...but wrong name...It is recognised as "AMD Athlon X2 3850e (Brisbane)"...

I am using the 64bit version on Vista Ultimate x64...

Thanx
