Neo2 cpu temp sensor

I just flashed to bios 1.A4 and now when I use corecenter or speed fan it shows the cpu temp to be 123C which I know isn't correct. Any ideas what is up with that? Also when using mbm which board is closest on the config to this board?

The problem is most likely that corecenter is reading a false sensor. This can be caused by if you have recently run a different type of temp monitoring program such as motherboard monitor, which allows you to select which sensor you want to use. You might try installing that and selecting the correct sensor, this will put the correct sensor reading in MSI Core Center also. Since this post is older I'm not sure if you still have the problem, but either way hopefully this help...

Cpu temp sensor burned

Hello all,
K7T 6330 V.3 with 1.3 Athlon
I recently changed my HSF to a presumably better unit than the one that came with teh CPU.
It ended up not cooling any better but running a bit hotter.
I removed all of the components I no longer used (old NIC, bad CDROM) to help air flow but after a few reboots to test the temp I smelt burning plastic.
I found that the CPU temp sensor inside the CPU socket was burned and now I only get red LEDs. The CPU and socket look fine. No debris of burn marks.
Anyway, if the sensor is burned to make an open circuit or shorted somehow, would this completely kill the mobo?
I mean, if ONLY the temp sensor circuit was fried, would this prevent the entire board from functioning?
thanks,
js

Yeah. Sorry if I wasn't clear on that part. The CPU definitely scorched the sensor. I may have inadvertantly pulled it up a little when replacing the CPU, only way it could have happened.
thanks,

3rd party CPU temp sensor??

Like others, my Neo2 is giving me wrong temp readings..
Everyone suggests an external temp sensor, but where do I buy one?

I don't think that you could put it right on the core itself, i could be wrong but i would put it right next to the core or right on the heatsink as close to the core as possible.
I remember when i used one of those thermal sensors on my abit VH-6, put it right on the Celeron CPU (coppermine core) and the temp for the cpu went right up up up! Reason being that the sensor was not allowing the core to touch the heatsink fully.
Just be careful not to sandwich it in between the core and the heatsink.

CPU temp sensors?

I´ve got a MSI 6330v5 motherboard, but it seems like, there´s no sensors for system temp. or cpu temp.
It measures my fans, and voltage fine. So there is a HW monitor, but no temp. sensors. Is it possible to add these sensors to the MB, or am I just f..... in that way?

FINALLY i'm back here at MSI!
i got a new HD from WD!
Got a new clean win xp pro, so i'm happy to be here again!
hi man,
go here http://mbm.livewiredev.com/
on the left side of the page you see the link 'motherboard list'. This site is made for users who runs motherboard monitor 5.
once you see your motherboard you will see the main sensor chip and the case and cpu sensors of your board.
there are 3x ms-6330 on the list, so attention is NEEDED before determining the sensor chips!!
i hope you will like that page and the software they provide.

990fxa gd80 cpu temp sensor?

My motherboard bios says my resting cpu temp (8350) is about 50 deg C. My Windows program Speccy (by piriform) show the resting temp about 27 Deg C.
Which one do I believe?????
If it is truly 27 deg C I will leave the stock cooler in. But if it is 50 I may get a bigger CPU cool.
Help?

I tried some other programs to read the temperature of the CPU. They all read the same...different from the MB. Much cooler.
I like the MSI board ok. But their documentations and support, and bios screens, all stink. The asus and asrock boards all have much better everything, except support. I have never found manufacturer support of MBs any good except for "we know nothing about it, but we will replace it".
But this forum is pretty good. Better than nothing.
Thanks for the reply!

MOVED: CPU temp sensor hitting 255C during stress test

This topic has been moved to Overclockers & Undervolting & Modding Corner.
https://forum-en.msi.com/index.php?topic=155824.0

Quote from: Bas on 12-January-12, 16:02:07
I doubt TMPIN0 is connected to anything, ergo your program is reading nothing.
If something was 255C then you would see flames comming out of the system.
Exactly, and the heatsink is cool to the touch and the fans slow down.
255 is simply the maximum value of 1 byte - a value that goes from 1 to 256 or in this case, 0 to 255. For some reason the sensor seems to bug out and report a value as high as it can report.

P6N Sli Platinum front audio panel and CPU temp voltage issues

Hi All,
I got my P6N Sli Platinum yesterday, build up my computer without any major issues. However I have noticed that my audio front panel does not work. It could not detect my microphone when i plug it into front auido panel, it works fine for the rear auido panel though.
Another issues is I highly doubt the accuracy of CPU temp sensor. Msi 's software monitor reports my CPU temp is around 19-20 degree, I know that's too good to be true even I am using a water cooling system. Btw my cpu is E6600. Anyone else has the similar issues?
The third, I notice my CPU voltage is bouncing between 1.1 to 1.24 in CPU-z. And the multiplier is changing from 6 to 9, frequency is changing from 1.6g to 2.4g. I only see this in CPU-z. Msi 's own software reports CPU running at 2.4g though. Is this cpuz issue or something else?
Finally, any tips to max the overclock potential of this board? I have overclocked to 3.1g but there are some crashes. Going higher the board just won't boot up. I read a review on anandtech.com says 1.22 bios is good for oc. Where can i download that? I only found 1.1 bios on official site.
Any reply will be appreciated.
Cheers

C2D-CPUs have a digital internal sensor to monitor CPU Core temperatures. Have a look at those with Core Temp ( http://www.thecoolest.zerobrains.com/CoreTemp/ ). This Tool reads the temperature data directly from the register of your CPU. There is nothing wrong with the sensor. It is rather the MSI tool that does not read the data it provides correctly.

There is no issue. What CPU-Z allows you to see there is the C1E-feature of your CPU at work. When there is nothing to do your processor will automatically reduce Core Voltages and frequency to save power and keep temperatures down. As soon as the work load increases the multiplier is set back to x9 and core voltages increase dynamically. It is meant to be a good thing.
I have overclocked my system a little and I like that the C1E feature is still working at this speed setting CPU frequency to 2GHz and core voltage to 1.144v when my system is idle.
If you have problems with this feature you can turn it off in BIOS. The option is labeled as "C1E Support" and might be hidden somewhere. You may be able to hit "F4" to unhide it.
The MSI utilities are not the best tools to monitor your system. CPU-Z, Core Temp, Everest, Speedfan, Memset, Rightmark Memory Analyzer for example do a far better job.

K8N Neo2 Plat cpu temp seems to be screw up...

Whenever I cold boot my system and when I went into the bios, my cpu temp will be like 40c while system at 28c then slowly raised to 34c which is reasonable. But cpu temp always around 40-42c not matter if I'm overclocking or not. I mean the cpu temp should be lower when cold boot and slowly raise depends on the room temperature right?
Sometimes it's screwed like cpu temp will reach up to 47c in bios and in windows when idle and when i reboot it's back to 40-42c using nvidia monitor and speedfan for readings.
Let's say when not overclocking, i set to auto for the vcore and it will shown as 1.35v. Even at 250HTT or more at 1.5v, in bios or windows, it's showing at 39-41c except for the load temp which i only see a difference.
It's just strange that cold boot cpu temp hit at 40-42c instantly and hardly moves even when vcore is at 1.5v in bios or in windows. Either that or it went up to 47c when idle sometimes but after a reboot, it went back to 40-42c again. I'm really confused why it's like this btw me using the stock cooler.

You took it right ! Is my english so bad...?? Bios ver. 1.5 shows correct readings after cold boot (yes when you are in windows and boot another time)
This 1.8 BIOS is not a Beta anymore. MSI will release this BIOS after their Holidays, many people in a german Forum are using it, without any problems!!
You should give it a try .... if you are experienced !!

Thanks MurdoK
I just flashed to bios v1.8 and the high temp of 40c when boot is fix
Now for cold boot, it's showing at 35-36c but the auto boot when psu switch is turned on showing blank screen with red/orange led light is not fix yet

Temp sensor

Is the temp sensor or corecentre weird on this board? Everytime I start pc, the temp says about 52, But I know thats wrong because If I start and go staright to bios it will say about 35-38. and also the fan stays normal when i get the bad reading.
To make core centre read correct I have to start pc, then restart straight away, otherwise i get the dodgy temp reading.
Think I better get speedfan or mbm

The whole core temperature reading scheme on the K8N NEO2 Platinum is peculiar. I'd swear that the bios is conditioning the actual reading from the Winbond Super I/O chip, for whatever reason. Perhaps an attempt to keep the uninformed blissful. No way I can keep the Vcore the same, reduce the CPU speed 20% and the Prime95 Torture temperature stays the same. No way!
I'm not sure, but if I can find an easy access point to the SMBUS, like the header you find on high quality motherboards, I may implement an external reader IC.

Sys temp sensor where is it?

I have just installed a water cooedl solution for my PC. Therefore I am watching temperatures closely to see how things are doing. I'm very happy with the lower temp for the CPU, but noticed my sys temp reading in core center is considerably warmer than my CPU temp. I am assuming the sensor for this is located with the northbridge with the chipset fan and heatsink Please confirm for me.
The CPU is running around 33C and the sys temp is running around 40C. I realize these temps are not a problem, but I would like to get the sys temp around the CPU temp. Would a water block for the northbridge be advised? other solutions? Thanks for any and all input.

Thanks for the picture. As usual, it's worth a 1000 words. That's all I wanted to know. According to MSI tech support the sensor is near the AGP port. Which of course agrees with what you are saying. Am I correct that the Nforce3 chipset shown on the picture is the northbridge? is the southbridge included?
Also, nobody answered my question about possibly using a waterblock on the chipset. Is this advised? Thanks again.
Nforce 3 250GB (Ultra use the same chipset) is a single chip solution , aka no southbridge & nortbridge chip .
Traditionally the northbridge has the functions of memory controller and AGP .
Southbridge has the other functions like I/O functions, such as USB, audio, serial, the system BIOS, the ISA bus, the interrupt controller and the IDE channels.
Nforce 3 250 gb does both southbridge and northbridge jobs , only northbridge function left is the AGP .
The memory controller is taken over by the A64 integrated .
So in other words , it's just as wrong to call the nv-chip northbridge as it is to call the A64 the northbridge .
Those words/definitions are no longer valid in a nforce 3 250 board as the functions and design is altered .
Is it neccesary to watercool the nv chip on nf3 250 , i think not , lots of people have very high overclocks with a aircoled chipset cooler or
even a passive heatsink from zalman ,or the stock cooler.
But if it's for noice reduction purposes it would make sense .
Though, on a nf4 board it would probably make more sense with a waterblock on it as that chip is mucho hotter .
Anyway , it won't hurt .
Also when connecting waterblock in series , cooled water from the radiator goes to cpu , then it's heated up and travels to the next waterblock without being cooled ,
and the next and returining to resevoir and gets cooled again by the radiator.
So having chipset after cpu , or after cpu + gfx doesn't actually give it that much cooling gain over a chipset fan if the case has good ventilating i think .
The water is never cooler than the ambient room temperature either .

3.0c cpu temps

I am currently running a P4 3.0c not overclocked with a thermaltake spark 7+ heatsink. My current cpu temp stays between 43-48 C under load as well as idle. Ive tried the stock cooler too. Any suggestions??

Mine is similar, 45-46 idle and 48-49 under load.
What mobo do you have ?
Originally, I assumed it was a faulty or insenitive thermal sensor, but others with the 865PE-Neo2 "P" series mobo's seemed to get similar temps.
Over the w/e I built another system for a friend, this time with a MSI 865PE-Neo2-PLS mobo and a 2.8 GHz processor and stock Intel cooler (he just wanted a stock system, no overclocking)... I test burned it for 24 hours running Seti@home x 2. Under stress the CPU temp was 49 under load and runs at 45 when idle (ambient 27).
It seems the "P" series boards just run cooler than its predecessors. Wonder how MSI did that ?

Correct CPU Temp?

Hello everyone.
how can i know if the cpu/nb/system temperature being shown from the bios and core center is accurate?
previously, my cpu reading @ idle says 44 degrees and reaches 65 degrees @ load. that was when my bios is v1.2 on my k8n neo - fsr.
i flashed my bios to v1.4, the reading is now 34@ idle and 45 @ load.
please help.

The problem was reported to MSI and the answer was that the bios does not read the winbond chip correctly on initial startup as it is only active after posting....
....Here is the way I understand it to work. For whatever little it is worth anyways.
Cold start
System board reads Bios info, if you enter bios at this stage; The Winbond chip has not yet been given the multiplier for the Core you have.
Continue to boot and the multiplier is passed to the Winbond chip along with VCore info and that is then transfered to the CoreCell chip to digest for Cool & Quiet to work, setting fans and adjusting multipliers for the chip as well as VCore for a given circumstance.
Unlike older systems that had the Temp sensor under the chip we have a built in Temp sensor in the CPU. These vary based on what core you are uses as read by the Bios. So until you boot up the first time the Winbond takes it's best guess based on I think the Clawhammers specs, which was the first core anyways for the A64's on the 754 boards.
As the Newcastles use a different Diode as a sensor those first readings will be off. If you have a Clawhemmer they settle.
MSI is not really at fault for designing the systems to work this way as AMD never told them they would be changing the diodes in the cores. So I am not sure it can be fixed. However if you do a reset after a cold boot post the readings should be OK I think from that point on.
In short, this problem is not going away, and a BIOS fix won't solve it. Tiresmoke is referring to the Neo1, but it's the same basic issue with Neo2. Also, Syar2003 posted a bit of interesting information on the temperature problems in the following thread:
neo2 plat and amd 64 temps post here
Not sure what's fact and what's fiction, but in the end, we just have to live with it I'm afraid. Good luck!
If the above explanation is *true* (and I very much doubt it), then this can only be described as a BUG.
There is no intrinsic reason why all the necessary initialisations and passing of data cannot be performed at cold boot as well as warm boot. To use this as an explanation - or an excuse - is pure hogwash.
If the bios has been programmed this way, then its plain stupid and needs to be fixed asap.

EDIT: Tiresmoke: The issue affects Winchesters too.

Neo2-F Temps AGAIN!!!!!!!!!!!!!!

ok so this is supposed to be a forum right... people read your topics and then respond... Well Ive gotten no response on my last topic so Im gonna post it AGAIN! K8N Neo2-F Temps seem to be way high!. its giving idle readings on the CPU of about 55C WITH A THERMALTAKE BIG TYPHOON!! Not possible... no ow it also says the northbridge is runnin at about 29C. Is it possible that the board has the sensors backwards? I need help!!! I dont need to fry my Athlon64 3400+ now do I?

My Neo2 Plat does the same thing... since BIOS 1.5.
With a XP90/Artic S/ & running low V in a well ventilated case my CPU temps have always seemed warm. But they never exceed 52C @ full load according to SpeedFan, so I don't worry about it anymore.
As long as it's not smoking!
The weird thing is that my temps with my Dual Core Opty 165 are reported to be EXACTLY the same as my old Winnie 3000 at the same settings & voltages and everything else (H/S, case & etc) the same. Seems like with Dual Core it would be warmer, if anything under any circumstances....
A lot of mobo's temp sensors aren't all that accurate anyhow. My old ABIT NF7-S (NF2 chipset) board was widely known to report CPU temps 4C higher than actual, no matter what on a consistent basis.
I'm not sure if this condition exists on any other of Nvidia's chipsets or MSI's mobo's - it would be nice to know though.

K9N-Platinum wrong cpu temp + nforce drivers problem

I have a msi k9n-platinum (ms-7250)
Cpu : Amd 64 x2 3800+

Asus 7900 GT
6 x maxtor sata hd's
Power : hyper type-r 580 watts
pioneer 110d
lg combo cdrw-dvd
When i builded the system , i installed Windows XP + Sp2 , made all windows updates
After i tryed to install the drivers a got wit the cd.
My system was very instable (i had no problem whit the motherboard i had before)
I made the install more than once , but still got instability
So i went to the nvidia site and downloaded the drivers for the chipset from there , and also made a bios update to v 1.2
System went stable.
Tried again after the bios update with the original cd --> not stable , randomless reboot
so i'm now working with the nvidia drivers from the nvidia site , it's stable but when i go to bios i see that the CPU temp is -38°
Is it a fix for this or do i have a wrong mobo ????

-38°C , seen that a few times now .
I think you should RMA/return the motherboard .
Why , see:

https://forum-en.msi.com/index.php?topic=94762.0
Not the same board as yours but all have a faulty calibraded (non workin) sensor on their motherboards .
The positive thing though is that the boards with this issue that runs on AMI bios doesn't freeze/halt as the award based ones does.
