After 6h Prime95.
Isn't nice temperatures :-(

I will searching better cooling.

your temps are so fine under 60C is very good

**ryaan** · 10-21-2006, 12:04 PM

is there a reason why core temp is very inaccurate for me? it shows both cores ~45c when speedfan shows 31/32c, bios shows 32/34c, eztune 5 shows 32/33c.

**Tallman** · 10-21-2006, 12:44 PM

core temp is within 1-2c of everest and TAT for me

The only reason is that CoreTemp/TAT (or Everest *Ultimate*) is able to show the readout (translated to temp) from the digital diode(s) in the core(s).
Bios, Speedfan, EZTune does not show coretemp.. well.. it didn't last time I checked.

I prefer looking at my speedfan temps. They're a good 13 degrees lower. =P

That's the case for me also with CoreTemp being lower.

I'm using Asus P5WDH with bios 1503 & E6700 .
While orthos priming with stock cooler and 1.45Vcore , i read a temperature of 124-128C . I don't know why , but straight after 85-86C it jumps to 125C .

Ouch, that is very odd.
What does TAT read?
What does your motherboard report?

How accurate is Core Temp?

TAT doesn't work as i use Win2k3 .
Asus Aibooster and all other similar programs shows 67-70C . That's approx 18C below core temp (when core temp shows right temp) .

See the attached pictures .

**Yoxxy** · 10-24-2006, 07:56 AM

I think your computer is on fire or has turned into some kind of a fission reactor, have you seen smoke coming out? (Kidding)

But seriously, 67-70c in Aibooster and you are not scared for 24/7. What is temp when running prime95 or orthos?

**Stelios** · 10-24-2006, 08:32 AM

OK . Small update .

I managed to run Intel TAT . Just needed to change the compatibility mode to win2000 . After 85C , TAT reads >85C . No 86C or anything else . Just >85C . At the same time Core temp gives 124-126C . So , mystery solved .

Previously i haven't encountered this , as all previous versions of core temp had the overheating pop up window which made orthos prime to loose priority.

These temps are while running orthos prime at 3.5Ghz & 1.45Vcore (Real vcore as i have made vdroop mod) .

Of course i'm not running this setup at 24/7 . My default cooling is a single stage (subzero cooling) . I'm just testing some CPU's .

Uhm i remember from intel datasheet that when temperature is higher than the maximum operating temperature (i.e. TJunction) an out of spec status bit is set in the DTS MSR. Maybe this is the cause of the odd behaviour of coretemp.

I'm pretty sure that chip is OVERHEATING
when a motherboard sensor shows you close to 70C that is very very bad.

Yes. That is probably it. the (?) at the end of the temp suggests it couldn't get a proper reading, so this value can be ignored.
I'll see that this gets fixed in a future release.
Thanks.

**domain** · 10-24-2006, 03:45 PM

thanks dude for this URL(The Way It Works)..
I'll send a feedback after trying it

**Mord** · 10-26-2006, 07:35 AM

Good, the new version isn't "crashing" after 1min. The system is in the sig. Previously it would close by itself after a while. Quite annoying.

0.93 that is.

Grats', mate!

One request (sorry if it has already been discussed) - could you please make the sys tray show temp instead of, errr .... nothing at all. 10x, keep up the good work!

**xgman** · 10-26-2006, 12:33 PM

Isn't there some way to get this to read the minus temps that clearly show in the asus bioses?

Yes, it has been requested dozens of times

, and I'm working on it.

Well... Core Temp shows what is read from the DTS, its a known issue with Intel CPUs for whatever reason, they just don't go lower than a certain temp, but never goes near 0C or under.
I've got no solution, I'm guessing that this is the DTS limitation.

**The Coolest** · 10-27-2006, 06:47 AM

My article which discusses motherboard temperature sensors and DTS has been posted just now here:

The latest Everest release reads minus cpu tems and so does MBM5 if you set the MB to the ASUS P4800. I don't know where they are reading the temps from, but they do see minus temps in Windows somehow. How can we see where MBM5 is reading this from? If you could duplicate that somehow maybe it would work?

**The Coolest** · 10-27-2006, 09:04 AM

If Core Temp doesn't read negative temps, no other program I know of will read negatives using the DTS either.
MBM5 and Everest are probably using the standard sensors.

hmmm . . so could core temp have an option to read those as well for the minus crowd at least? Where is the asus bios reading the minus temps from? Funny how even the asus utiliies can't see the minus temps that their own bioses shows clearly.

**The Coolest** · 10-27-2006, 10:39 AM

If you read my article, you'll notice that's Core Temp does not read, nor has access to any Super I/O chip. So, sorry, I'm afraid I can't

**gooface** · 10-27-2006, 10:59 AM

is there anyway that this will tell the true volts of the cpu not the ones that are meant for it?
