asus m3a78-cm e allarme voltaggi

[akiro]

Ciao a tutti,
Su un pc con motherboard asus m3a78-cm, phenom II x4 920 e la Mandriva 2009.0 64bit ho installato gkrellm e lm_sensors per monitorare temperature, velocità delle ventole e voltaggi dei componenti, adesso però mi compaiono su /var/log/messages un sacco di errori per i voltaggi:

May  7 00:49:21 picci sensord: Sensor alarm: Chip it8712-isa-0290: +3.3V: +3.34 V (min = +0.00 V, max = +1.97 V) [ALARM]
May  7 00:49:21 picci sensord: Sensor alarm: Chip it8712-isa-0290: +5V: +6.85 V (min = +6.42 V, max = +6.85 V) [ALARM]
May  7 00:49:21 picci sensord: Sensor alarm: Chip it8712-isa-0290: -5V: +4.03 V (min = -13.64 V, max = -4.84 V) [ALARM]
May  7 00:49:21 picci sensord: Sensor alarm: Chip it8712-isa-0290: Stdby: +6.83 V (min = +0.00 V, max = +3.41 V) [ALARM]

Mi devo preoccupare?
Le impostazioni del BIOS non le ho modificate.


per esser precisi questo è l'output di sensors-detect quando l'ho installato su Linux:

# sensors-detect                  
# sensors-detect revision 5291 (2008-06-23 23:40:46 -0700)

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe  
and recommended to accept the default answers to all questions,   
unless you know what you're doing.                                

We can start with probing for (PCI) I2C or SMBus adapters.
Do you want to probe now? (YES/no): y                     
Probing for PCI bus adapters...                           
Use driver `i2c-piix4' for device 0000:00:14.0: ATI Technologies Inc SB600 SMBus

We will now try to load each adapter module in turn.
Module `i2c-piix4' already loaded.                  
If you have undetectable or unsupported I2C/SMBus adapters, you can have
them scanned by manually loading the modules before running this script.

To continue, we need module `i2c-dev' to be loaded.
Do you want to load `i2c-dev' now? (YES/no): y     
Module loaded successfully.                        

We are now going to do the I2C/SMBus adapter probings. Some chips may
be double detected; we choose the one with the highest confidence    
value in that case.                                                  
If you found that the adapter hung after probing a certain address,  
you can specify that address to remain unprobed.                     

Next adapter: SMBus PIIX4 adapter at 0b00 (i2c-0)
Do you want to scan it? (YES/no/selectively): y

Probing for `EDID EEPROM'...                                No

Probing for `EDID EEPROM'...                                No 

Some chips are also accessible through the ISA I/O ports. We have to
write to arbitrary I/O ports to probe them. This is usually safe though.
Yes, you do have ISA I/O ports even if you do not have any ISA slots!   
Do you want to scan the ISA I/O ports? (YES/no): n                      

Some Super I/O chips may also contain sensors. We have to write to
standard I/O ports to probe them. This is usually safe.           
Do you want to scan for Super I/O sensors? (YES/no): y

Some south bridges, CPUs or memory controllers may also contain
embedded sensors. Do you want to scan for them? (YES/no): y

    (driver `to-be-written')

Now follows a summary of the probes I have just done.
Just press ENTER to continue:                        

Driver `it87' (should be inserted):
  Detects correctly:               
  * ISA bus, address 0x290         
    Chip `ITE IT8712F Super IO Sensors' (confidence: 9)

Driver `to-be-written' (should be inserted):
  Detects correctly:                        
  * Chip `AMD K10 thermal sensors' (confidence: 9)

Do you want to generate /etc/sysconfig/lm_sensors? (YES/no): y
Carico i moduli dei sensori:                                  
Avvio di sensord:                                               [   OK   ]

Cosa posso regolare sul BIOS per far sparire gli allarmi? controindicazioni?

Grazie a tutti.
