Hi. My name is Fabiano and i hope that it's the right place to post my
problem. I've just purchased on ebay a motherboard Asrock K7S8X Rev.3.
I've only one problem with this motherboard: the hardware monitor, in
the bios, show always 127°C for the cpu temperature. The temperature
for the motherboard is correct; in fact i can see change the
temperature from 20°C to 30°C but for cpu temperature nothing change:
always 127°C. I tried to update bios to the last version (2.60) but
nothing changes. My configuration is listed below:

Athlon XP 1900+ 1600Mhz (133 * 12 setting with jumpers)
Asrock K7S8X Rev.3
Power supply 400W
N°2 * 512Mb PC2100 Viking
Ati 9700 Pro 128Mb
Hard disk 80Gb Maxtor
DVD Writer LG

How can i solve my problem? Please, help me!
Thank you in advance for your cooperation.
Greetings.

What program are you using for temperature monitoring? I would think its
incorrectly set up. Try Motherboard Monitor.http://mbm.livewiredev.com/
 
I've tested with the bios, Speedfan and Motherboard monitor but nothing
changes! Always 127°C.

There are at least 5 different motherboards that start with
"K7S8X", including,

K7S8X R3.0
K7S8X
K7S8XE+
K7S8XE R3.0
K7S8XE

Are you certain you have the right bios for your
motherboard?

Sometimes a very similar board will run, work with the wrong
bios but would have small problems like this.

If you are sure you have the correct bios, you might try one
just a little older than version 2.60.

There might be someone else with this motherboard in the
motherboard forum at
http://forums.pcper.com/forumdisplay.php?f=14 ,
you could search there or post your question to them.
 
As i wrote in my first message my motherboard is K7S8X R3.0. I know
that there are many types. I've installed the right bios and with
version 2.20 and 2.60 the results are the same: temperature at 127°C.
I'll try, also, to post at the forum indicated by you.
Thanks.

A picture of one of the K7S8X family, shows it uses the
Winbond W83697HF. That chip has two temperature monitoring
channels.

http://winbond-usa.com/products/winbond_products/pdfs/PCIC/w83697hf.pdf

A typical measurement circuit is shown in Figure 9.3 on PDF page 28.
The chip uses a lookup table, to convert the measured voltage to
a temperature (Table 2 PDF page 27 shows the temperature coding).

I guess the first question I'd ask you, is how many temperature
readings does the BIOS show on the screen ? Does it show just
two (CPU and motherboard temperature) ?

Have you tried running MBM5 (mbm.livewiredev.com) or
SpeedFan ( http://almico.com/speedfan.php ) ? Those Windows
programs can read temperatures from the monitor chip, if
the program is configured correctly by the user. Perhaps you'll
get correct readings there.

Since there are so many versions of the board, there
may be a different "Super I/O" chip on your motherboard.
But if you find the chip on the motherboard, and use MBM5
or SpeedFan, maybe you'll get a better temperature readout.

Yes it shows 2 temperature: cpu and motherboard. I've alrso tried
bothn(MBM5 and Speedfan) but nothing changes. The tempersture is always
127°C.

Hi. I've received this suggestion: someone told me that my
motherboard have not the external sensor for the cpu temperature but
only the internal sensor and, for this person, my Athlon XP 1900+ have
not the temperature sensor. Is correct this information or not?
But now i've a doubt: how could i know if the problem is really the
motherboard? Is it possible that the problem is caused by the cpu?
Thank you.

The picture of what was supposedly your board that I saw,
did not have the external sensor in the CPU socket-well.

However, Athlon XP does have the internal sensor, all Athon
XP do.

It's really the motherboard. Most likely it's either
engineered wrong or the reading for temp is pointing to the
wrong address and if you knew the correct one you could get
the temp reading. You might try fiddling with the settings
in Motherboard Monitor to see if any of them produce a
reading in the expected range and that vary with system
load.
 
I've also checked with Cbid and the result is:

Sensor model: Winbond W83697HF 128-PQFP
Version number: 18
Sensor type: Super I/O

Bye.
