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.

[Utnorris]

What does the offset need to be on a 45nm CPU, specifically a QX9650? My temps are lower than the previous version, 99.1 and if I remember right I had to do an offset with it also. I cannot compare my temps to my MB since I did the Rampage Bios mod and my temps are being read wrong from there.
Thanks,
Utnorris

[The Coolest]

No offset is needed for 0.99.3

[The Coolest]

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.

And please, could someone fix the title of this thread?

Hi and Thanks for new release ..

maybe ''bug'' ? in Coretemp 64bit version .. when running W7 beta 64Bit
Ok not complaining or what so ever .. though both are still BETA versions
anyway .. other programs seems reporting correct numbers?
so .. just decided to leave a message unfortunately dont have other 64bit OS to recheck

-- don't know but seems CT 099.4 64bit is reading wrong fsb ->
like 444 .x mhz -> instead 400 mhz (what i set in bios) - calculation is correct number ( 10*445 = 4445 ) ..
but it is wrong core (cpu) speed for current situation in Win7 beta 64bit

ok here trying to run QX9650 @ 4000mhz - 10x400FSB / strap400 // DDR3-1600 ( 1:2 )
Rampage Extrem bios v1003 / 4GB ram
( 2x2GB) A-Data PC12800 (DDR3-1600)
- corect reading should be ~ 4000 Mhz but - it show 4440Mhz

screen : ................... bios capture

[swale]

core temp is still buggy for me reads my temps around 50c idle (wc'd) and says my multi is 21x when its 20x (idle of course)!!!???

finding realtemp better, on my i7

[Strages]

Works great for me - I actually like this program better than Real Temp because of the built-in G15 applet. Core Temp and Real Temp read the exact same temps for me, so I'm happy!

Swale: What does Real Temp read? Have you set the TJMax correctly?

That's a known issue. You can select "Use alt. frequency detection" in Options --> Settings. It usually sorts that problem out.
I'm actually working on getting this fixed for a future release.

Do you have Turbo mode enabled? Core Temp displays the multiplier which it reads directly from the CPU, I'm fairly sure that part of my code is correct
Regarding temperature, the same thing. Core Temp reports whatever is in the register responsible for reporting core temperature to software, if the sensors are reporting wrong temperature, what software you use doesn't matter.

[The Coolest]

Change log since the previous beta:

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

- 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.

Thx sir , good job !!

[burebista]

Minor glitch? Vista64 SP1. Everest 5.0, RMClock and RivaTuner running.

[The Coolest]

Sure is, will fix and upload a fixed build ASAP. Thanks.

*EDIT:*
Build 6 is up, same URL.

[burebista]

Sorry, same 5 build is downloaded. Tried with Firefox and IE.

[burebista]

OK, done. Build 6 is up and everything looks fine.

[The Coolest]

Great, thanks

[Strages]

I really, really like this program. It's just as good as Real Temp (they read the same temps too ), but the G15 applet makes this program much better for me! Real-time monitoring all the time in any app! Anyhow, this is just a simple, selfish request - I'm wondering if you could add GPU monitoring to this program as well that could also show up in the G15 applet. If that's not in the "mission" for this app or whatever, it's still a great little app. Keep up the good work and updates regardless!

[The Coolest]

When I get some free time I'm going to write a GPU temperature report plugin.
I haven't decided whether it's going to be an actual plugin or something I'm going to integrate into Core Temp (but will come as a separate DLL file).

Here's the preliminary test:

This only works on nVidia GPUs so far. I use nVidia's NVAPI library they provide on their developers' page.
I'll have to dig around and see if ATi offers something similar. As far as I know they don't, so if anybody has any information to share about it, please do.

Same QX9650 bug where 400 reads as 444 - it didn't do it initially though, only just started... only on anything above 400.

Will download new version tonight. Look forward to having GPU's intergrated
