Voltage and Temp, am I in danger? 165 + expert

[IvanAndreevich]

I think 45C on the expert is way above 50C on the non-expert so that may be kinda high.

Everybody should read FAQ on CBId to uderstand the Thermal Offset.

A linky would have been useful!

From experience of 2 Expert boards, I can say they report 8C to 12C too low. e.g x2 3800 dual primed 2500 stock HSF 43C in Expert, 54C (max) in A8N32 (assuming the Asus is near the mark, it's about the same as an Asrock Dual). I should say that the thermal offset is 5C, so 49C is closest figure to reality.

So does that mean what I said originally was correct? Is that calculated before your temp is displayed in MBM5/whatever or do you have to add/subtract yourself?

[soundx98]

@ VVJ and Repoman. I am confused as well.
Not familiar with the program and it doesn't load driver in x64 (primary OS)

This is a screenshot of CBID (latest) in XP Pro on an Ultra-D.
Are you saying my Opti is reporting 9 degrees too high?

An external temperature sensor, for example any Winbond or ITE super I/O chip, uses processor’s on-die thermal diode to measure its temperature. Diode offset should be always subtracted from the temperature sensor reading. I suspect software doesn’t use the thermal offset at all. MBM is too old and doesn’t know about this parameter. Authors of Everest and Sandra don’t know an actual purpose of it at all. The best way to check whether the thermal offset should be subtracted or not is to make a comparison of the room temperature with the processor’s one on start.

[stone_cold_Jimi]

Yeah, I'm doubtful now you say that. My s754 Venice @ 2550 / 1.44v running 100% on rosetta@home is hitting maybe 35C indicated on water, room about 20C. The offset is 13C. Is it really running at 22C then? I'd like to think so, but I have serious doubts. I need an independent method, like a water temp thermometer.

[VVJ]

Yeah, I'm doubtful now you say that.

I have read a lot of technical documents and each define the same statement: “diode offset should be subtracted from the temperature sensor reading”.

[stone_cold_Jimi]

OK, I must check the water temp. It's cooler than ambient for sure, so it might just be true. Dual BlackIce Extreme rad, 2x 120mm fans, maybe, just maybe.

This is my other Opty 146 CAB2E 0540FPMW.

A 20 degree temp offset? One has a 9 degree and the other 20 degrees in virtually identical rigs. Just doesn't seem right

I agree, it seems unlikely - unless it's added on. Look at this (13C offset):

http://xtremesystems.org/forums/show...&postcount=350

It's far more likely, given the voltage, that the 34C indicated figure is 47C true rather than 21C (ambient was about 20C). I really don't know what to believe, tbh.

[palehorse]

I don't think you will ever see 9C.. that means it will over-report your temps.

I have been telling people about the thermal offset for over a month, no one listens

I think I am right because with my Opteron 148 with 0C offset, I ran 30 idle/50load/25Ambient on BT/Ultra-D. That's at 2950MHz and 1.55v. I pop in my brand new 165 in the same board/cooling, check the thermal offset and it's -8C.. and I run 22C idle in 25C ambient on 1.475v I doubt that dual core lowers my temps over single..

So same MB and wrong temps, plus I've had 3 Opties now to confirm.. a 0534, 0550 and 0551. -8C, -7C and -7C offsets and they all idle below ambient and never go over ~42-43 on load even with high volts

BTW, you find this in a program called central brain identifier, not in BIOS- to Justin

edit: auto shutdown is no good, not that it matters because it shouldn't get that hot. And the voltage you should assume you're running is what you have selected in the BIOS, until you measure with a DMM

Just an FYI: CBI offsets are completely useless in determining your actual temperatures... My CBI offset reads -8C when my chip actually reads 16C low! (which would mean CBI should say -16C instead)

trust me, if there was an end-all software solution to solve all of the Expert mobo's temperature reading problems, I'd hopefully know about it, and give the person who wrote it my first born! (lol, i kinda helped lead the charge over at DFI street to get temperature readings fixed...for awhile...but, needless to say, i dont think DFI cares anymore... )

Sooo, using some mathematics AND proper testing with a thermal probe, I came up with my real offset that i set manually in MBM5... and even THAT is probably off by 1-2C!

I said it over at DFI, and I'll say it again: I sometimes think it's hillarious when you imagine all of the things your computer is capable of, such as searching for ET, rendering billions of polygons, and calculating 32M PI in minutes; BUT, the damn thing cant even tell you the temperature of its main component within 1/2C!!?! How long ago was the digital thermometer invented?! lol... oh the irony!

Thermal offset is a specific parameter for any processor and is programmed at the factory while technological testing. A correction to the offset may be needed for some temperature sensors. Contact the temperature sensor vendor or motherboard vendor to determine whether an offset correction is needed.

It's a shame that nextsensor program doesn't support any of the latest boards that use the ITE8712F sensors. Is anyone doing any work on that?

Thanks for the information and keep us informed of any updates.

[VVJ]

You’re mistaken! There is no any shame. NextSensor supports IT8705F, IT8707F, IT8708F, IT8710F, IT8711F, IT8712F and the latest IT8716F. It will be released in a day or two. I just need more time to test it completely.

[soundx98]

Fantastic news. I'm very excited to try the latest version as well.
Will the program automatically compensate for the Thermal Offset or is there a plug-in you can help us through?

Thank you for all your efforts. I'm willing to test an alpha/beta if I can help in any way.

[soundx98]

@VVJ - thank you. You have PMs and some comments.
Respect

I run 24/7 1.65v on a opty and its fine. Also did on my 3800X2.

Temps ok then 1.6-1.65v is fine

[blind_ripper]

u pepeol are all wuss i give my x2 4400+ 1.75vcore on wc voor benching @ 2.915ghz and i give it 1.72vcore on a modded promm@ 3.15ghz . i have given it 1.87vcore for ss np at all ist te board that can not handel the vcore not the chip !!! , this is not for 24/7 he

[Grinch]

this might sound like a dumb question...under brain identifier..pstates...says....-7 for thermal offset...is this -7C or F?...nevermind I see -7C...DOH

[Grinch]

just did some quick math...if pstate says offset is -7C that would equal 19.4F now in motherboard monitor when I select to compensate cpu temp under celcius to -7 in the farenheit portion it changes to -12 instead of like -19 ....understand what I am saying?

You need to add no take away

[Grinch]

You need to add no take away

so you are saying that negative 7 means....add? is this just for expert boards or all boards?

[mnewxcv]

-7 means ur board reads temps 7c lower than real.


anyone know why my fx-51 reads 22c? not negative

[Grinch]

I think it is all wrong and I will go by a thermal probe...
