Find out the Max Case Temperature and Max Power draw of your CPU

[situman]

This test seems to be pretty useless. x2 3800 has a much higher maxcaseT and I can clock 250mhz higher.

[periquitos]

you must only compare similar processors.

mine 170 0530tpmw has 53deg , want to see another results from the same week...

Why doesn't this programme work for me?

I get the same thing showing, but if when I hit copy to clipboard and paste it into a text doxument I find I have values for the Max Case Temp and TDP, 49c and 35w respectively on an Operton 175 CCBWE 0544XPMW, but there is something there

How does this work exactly? Since my Cpu overclocks well, is that why I got low TDP? What does lower MaxTCase mean? That is has lower tolerance to heat? Also, would MaxTCase and TDP explain why my CPU hates volts over 1.45V?

Anyway, here's what I get:

How do I know which version I have... and does the program now which CPU is which..?
Also.. even if I have the 110W thermal power version which is rated at TMax 65C... how come mine can only handle 55C according to the program...?
10C difference is a lot.. especially for a $550 chip..

[palehorse]

With my chip overlocked to 2650mhz, i get this is the AMD64 TCaseMax v1.18:

TMaxCase: 49C
TDP: 35W

Ok, what exactly do the TCaseMax and TDP mean there? The rated wattage of my chip is supposed to be 110W, so what do those values above represent in relation to actual output wattage?!

[Dragoran]

Download AMD64 TCaseMax v1.17.

This is a new type of program, which checks AMD64 CPUs for their maximum rated case temp or TCaseMax and reports the TDP which corresponds to the processor in question.
On most AMD processors TCaseMax and TDP values are constant, and depend on CPU type and model, but on the E Revision chips, both this values and the default voltage are variable.
These are the chips that have variable values:
Athlon64 (Venice, San Diego)
Athlon64 FX (San Diego)
Athlon64 X2 (Manchester, Toledo)
All Rev E Opterons and Dual Core Opterons
What this all means is this: On 90nm manufacturing process, the power leakage of transistors on individual processors differs greatly, this is why AMD implemented TCaseMax. Each CPU has a different TDP rating, here's how it works:
A program reads the TCaseMax value off the CPU, then depending on the processor (CPU type like A64, Opteron;CPU Rating like 3500+, 146) it finds the processor's Thermal Profile (If you download the "AMD Opteron™ Processor Power and Thermal Data Sheet" and look at pages 10-11 you'll see the different thermal profiles). When the thermal profile is determined, the program finds the TDP rating that corresponds to the CPU's TCaseMax value.
So in a few words, the higher the TCaseMax, the higher the TDP of a processor will be (the transistor leakage is higher), so the processor will run hotter. Several people have reported that the Opterons rated at 71C TCaseMax were pretty hot. On the other side these processors will be able to reach higher clock speeds.
That is why we see that on average processors with higher TCaseMax can usually reach higher CPU speeds when overclocked.
Every CPU type (A64, FX, X2, Opteron, DC Opteron) has a different thermal profile, that is why you see that on an FX a TCaseMax rating can be "only" 57C and it'll overclock way better than an A64 with a 57C TCaseMax rating. That is because at 57C TCaseMax, an FX has a TDP of 77W while the A64 has a TDP of 44W.

If you want to post a screenshot press Alt+PrintScreen and paste it in paint and save in PNG (if you have WinXP or Win2003). Pictures do speak a 1k words Or at least click "Copy to clipboard" button and paste the text here.
*Note: The "Create stats file" button doesn't work yet, but it will work soon, where it'll create a file that you'll upload to a website and it'll add you to a DB of chips and there will be statistics of different CPUs.


What's new:

Version 1.17
Fixed a bug with incorrectly showing Dual Core FX PR number.
49C TCM chips will now be reported again, no "This CPU does not support TCaseMax feature." messages anymore.

Version 1.16
Fixed a bug with newer HE DC Opterons not showing the proper TDP.
Fixed a bug with the naming of HE and EE Opterons.

Version 1.15
49C TCaseMax is not used anymore, this means that for any CPU which returns 49C TCM (like the new Dual Core Opterons), the program will report "This CPU does not support TCaseMax feature."
Extended the 'D' Thermal Profile, as some chips using this profile have reported higher TCMs than the highest TCM specified in the profile.

Version 1.14
Serios bug fixed. Program would not show information about any processor that was an E revision CPU.

Version 1.13
Athlon 64 FX thermal profile fixed.

Version 1.12
Renamed to "AMD64 TCaseMax".
Added support for FX-60 and Dual Core CPUs with 1 core disabled.
Several bugs fixed.

Version 1.11
Several bugs fixed.

Version 1.10
Added TDP - Will now report the TDP (Thermal Design Power, or in other words the maximum power the CPU draws at stock speed/voltage)

Version 1.04
First version with all new AMD CPUs supported.

Regarding the stats... I decided to remove them as they are practically useless right now. I will hopefully put a up a page where you will be able to upload your results, and then compare your results to a database of other chips.

I am interessted in how this programm works...
I searched the amd tech docs for a way to read tcase max using the cpuid call (are you using it?) ut could'nt find anything
found it in the BIOS and kernel developer guide

I have a 170 CCBWE 0546XPMW that is stable at 2700 with 1.46volts... so far I'm priming at 2800 @ 1.6volts for 2 and a half hours and still going my max load temp is 38C with water... I'll tell you for sure in the morning

[alpha0ne]

Hang in there Hassan, that week 170 (see my sig) are good for at least 2.9GHz 100% torture stable with less than 1.6Vcore after burn-in

[Serge84]

This is a maximum temperature of CPU's case, that is a temperature on it's Heat Spreader (nothing to do with case, power supply, HDDs ect.). It is specified as absolute maximum rating. AMD say the CPU is certified to work up to this temperature. When you have higher, it may produce errors, it may fail, burn, whatever. And you loose your warranty when you run higher.

This is no joke, look into datasheets.

My Tcase max is 65C. When we reach the max of this temp does the Tcase melt? if we take the Heat spreader off does this increase the temp in witch the CPU can survive at because it has no heat spreader?

Well, surely its not the temp where the Tcase melts. Mine is 49c and the proc has been at 53c in SmartGuardian, so...

But maybe thats the temp where the proc starts to error? Makes sense, mine stops priming when ~50
