so does this just add the offset to mobo reading ?

Is there a reason why no other program for 3 years has been able to do this?

i was wondering the same thing?

This feature was undocumented in any documentation prior to the official implementation in RevF chips. A user reported that this could also work on his RevE chip, and after some digging around and testing it appears to work on all the chips since the early Rev C0.

Question about this, I load it up and it says my CPU is currently at 44*C - no wait, 45.. uh 43... now 45 again, back to 44.... 45... 43.. 44... why is it bouncing around so much?

By the way Asus PC Probe reports CPU at a steady 41*C

To be completely honest, I don't know.
I assume this happens because the load is completely constant, and as this is an internal probe, it updates at very high speeds, thus reporting any minute change in temperature.
RevG will bring accuracy of 1/4 of a C° to the table!

so does this just add the offset to mobo reading ?

No, current build 86 has the "Offset" part removed, after I added it in 85 and got some very odd readings on some chips.
The program also doesn't use any sensors found on the motherboard. It gets the temperature directly from the CPU.

Wow..so for the first time we can have realistic temp readings...terrific

cant wait to get home and see what my opty 170 0550 vpmw is reading

downlaod link is not working

can anyone send it to me through email ahmad.okda (AT) gmail

Everyone spend $10 and get a working thermal probe. Which will be accurate to 0.01 Degrees C. Thus you will know EXACTLY how close it is to the real thing.

And how exactly are you supposed to get the thermal probe inside the CPU? If your just measuring the outside temperature, it will allways be way lower than the actual core temperature, even if you peel of the IHS first.

BTW, can anyone answer my why exactly this program is supposed to be more accurate than other temp monitor programs? They are all reading from the same senors inbeded in the CPU, are they not? Then how can one be claimed to be more accurate than the other? (or why are they showing different resutls in the first place...)

hmm...

Link is working fine for me.

I've just hosted the file, try this: http://lites.no.sapo.pt/CoreTemp.zip

I also hope The Coolest doesn't mind, if so I can remove the file, just drop me a PM!

Well, the "accuracy" part is now quiestionable, as not all sensors are probably callibrated to perfection, but I bet it reports temps closer to the real core temp than all the other programs as they read what the mobo sensor reports, that's also why the readings vary between Core Temp and all the other software, also if you notice the screenshots of Dual Core chips you'll see that the program reports temp of EACH individual core.

No problem, the only thing is to keep it updated

[nealh]

My findings are interesting...

I am on WCing in sig

Opty 170 0550 VPMW revision JH-E6

Speedfan: idle: core 0 & 1 31/32/33
load: core 0 & 1 41/42/43

Core Program: idle: core 0 22/23/24 ..this lower than my ambients which 24-26C
core 1 26/27/28

load: core 0 49/50/51
core 1 41/42/43

I do not thin kthis is accurate for me....

So basicly, all the other programs to date have been relying on motherboard sensors? I haven't really researched into that. I was just assuming support for reading the internal sensor was implemented shortly after the CPUs started to come equiped with them.

But yea, if thats the case, then obviously the internal sensor will be much more accurate, probably as close as close to a truthful reading that we can get, depending on the quality of the sensors themselves (which I assume are within 1-2 degrees maxium given todays technology).

You should definately contact the creators of the other popular monitor programs and share your findings so they can implement the same into their own creations. Not that your program isn't adequate, but it would be a shame not to spead the information. I assume that commercial profit from this isn't your goal anyway =)

my opty 170@2.75 result

• idle Core''1 26c Core''2 23c
• 
• load Core''1 47c Core''2 38c
• 

• cpu load Core''1 & Core''2 ____ 9c different way?

[NickS]

They're different cuz your IHS isn't making good contact with both sides.

It could also happen because no CPU is created equal. I've noticed the same fenomena in Yonah CPUs and they don't have IHS. Its quite possible that one core is that much hotter than the other. There is a 3C difference at IDLE.

I would also like to see pics of idle, load core0/idle core1, idle core0/load core1 and load both cores.

[akijikan]

reports stock voltage, even though I'm actually higher

[CHaynes112]

Just tested on the system in my signature. There was something weird I noticed... at Idle, Smart Guardian shows the same temperature as Core #1 (in Core Temp), however, at Load (dual Prime), Smart Guardian shows the same temperature as Core #2 (in Core Temp)?! Anyone else notice anything like this? I am guessing SG can only "detect" and display one temperature... but it seems as if it actually "jumps" to different cores between idle and load...?!

it only reads the VID value and not special % value

pming hey

[3oh6]

hey The Coolest...is there anyway that a naked core vs an IHS covered one would result in a false reading. i have a 3/8" waterchill loop setup on one test rig and on my 3200+ AM2 I would load around 45-50C @ 2.8GHz depending on ambient temp.

a few minutes ago i popped the top on the little sucker and put it back under water...almost 20C drop in load temps was the result. i am not one to trust such a wide swing and was curious to know if you think a naked core would effect the temp readings that much?

It's Possible that your IHS was making really bad contact and now without it, it really is 20 degree's cooler.

I popped my Top today and my full load went down about 10-11 degree's.

yeah, anything is possible, but is it more plausible that the reading is being effected by the core being naked or that the temps actually plummeted that much?

i couldn't get 3GHz prime stable for the life of me before on this chip so i guess if i can stabalize it there then the temps might actually be lower.
