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

[cujo]

don't think i've posted here yet so here goes.

idle:


load:


this is with the top popped. taking it off dropped my temps approx 3c on each core load. idle remained unchanged. i was really hoping that my core temps would be the same after popping the top but oh well. btw, core 0 fails first at 2.9ghz with same 1.4v set as at 2.8 even though it's clearly the cooler core. go figure.

Yah same here, after I took off the IHS it dropped core0 temp about 15C! as it used to be way higher than core1 and now it's even a few degrees cooler than core1 (52 - 54C loaded, vs 55 - 57C core1 @ 1.45v) but still fails sooner than core1.

no wonder it does 2.9 at stock voltage

Looks nice i think i ll try it.

here is screen shot of core temp on my freaking manchester when running prime...is my cpu like on fire or something?

Thats really hot, Im running a Zalman 7000ALCU on this thing.
Its running at 1.52v accoring to bios/cpuz and speedfan.

Speedfan's normal CPU reading(not core one) is reading only about 55C

No its not...

Temp Core its just a non acurate program.
Unless you installed in a wrong way your heatsink there should be no problem since many AMD CPUs have a trothle temps between 65-70C.

No one knows the accuracy of any of these programs. But it's impossible for Core Temp as a program to be inaccurate. All it does is display the value of the thermal sensors. Any inaccuracy comes from the sensors themselves inside the processor.

I thought the throttle of 65-70C was for the TCasemax value?

Hi guys

I'm just wondering if you people trust the reading taken from SmartGuardian.

The reason I asked is because Smartguardian is telling me my CPU is running at 72C, yet when I run Core Temp and Speedfan, they both tell me my CPU is running at a much more respectful 35C

How is it possible that Smartguardian's reading is so much higher?

[cky2k6]

cause its reading the wrong sensor or something. quite ironic for the mobo's own program to read the temp wrong, but smart guardian isnt known as the most trustworthy program by far. if it was really that high, you would not be running stable. same for the previous guy, temps that high are right at the stable threshod, if not higher, so the program is most likely wrong. temps like that wont really do anything more than make the cpu unstable anyways. 80+ is where it is probably a little more worrisome cause of the mem controller more than the chip.

Thanks for that, the PC is running rock solid at readings of 72C. I have been running Prime95 for the last 26 hours without errors.

I guess I should just ignore the readings given by Smartguardian

even that... the final result is turning into an innacurate reading using a bad sensor with a conversion.

An accurate reading is to hard to manage...

Once again, comparing Core temp to Tcasemax does not tell you anything.

Core temp is the running junction temperature and should be compared to Tjunctionmax.

Tcasemax, the "Tcase", is referring to the temperature on some surface on the IC module.

The Core Temp program in the OP is probably reporting an accurate Junction Temperature. But the problem is that you're not given Tjunctionmax by Intel or AMD.

This is the millionth time I'm trying to convey this in different ways.......

Someone please pick up a book on IC thermal management.

Well, I`ve downloaded the newest core temp and the newest speedfan, coretemp alway`s does like 10 degrees above the speedfan temps.

which program is accurate ?

Speed fan web site says:

added full support for AMD K8 (Sempron, Opteron, Athlon 64) internal temperature sensor

If speedfan supports temp reading from the cpu's internal measurement you will see this in speedfan:
Speed Fan = Core Temp

Update!!!
New version is out!
Core temp now has its own website, no more posting and downloading it from a forum thread.

Read the 1st Post for the links and info

[Okda]

the link to the prg doesn't work ever for me, i am located in Egypt and don't know what si wrong

can you please host it on filefront or here on the forum for example so i can get it

sorry for bothering but i have been facing this problem since the start of your thread with all versions

Thanks for the great work The Coolest

Your site is now added to my favorites

[The Coolest]

Thanks for notifying me, I'll see if I can get an image up on some other website.

[The Coolest]

Mirrors are up on the main page of the website

[Okda]

Thak you very much

still can't figure otu why i can't load the original page

I recently purchased a Swiftech Apogee swapping from a DD TDX block as I unfortunatly brought the BEST THING SINCE SLICED BREAD info on the Swiftech web site.

Ive been using this block now for a couple of months, however a couple of days ago I was stress testing my CPU (AMD X2 3800+) using Stress Prime orthos edition, opened up core temp, I noticed that one core temp was around 55oC and the other was upto 72oC , any how this CPU has recently died and gone to heaven, (Mrs's nagging fault) , so I nicked the CPU out of her machine an AMD X2 4400+ , started overclocking it, while stress testing once again with orthos edition of Stress Prime, and Coretemp runing, I noticed I have the same problem with this cpu, one core hanging around 55oC and the other upto 70+oC

I find it very strange that 2 different CPU's can be suffering exactly the same problem.

Any help on this issue would be greatly appreciated.
