MoBo Temperature monitoring/Throttling?
« on: April 18, 2012, 03:31:15 pm »
Can Motherboard temperatures be monitored or throttled?  Here's what I ran into with a new ASUS M4N68T-M V2 MoBo.  The CPU (AMD 125w 1090T Phenom II) was constantly downclocking to half its normal frequency when crunching BOINC tasks.  I monitored this with TThrottle's temp graphs (sawtooth pattern as it downclocked and then resumed normal frequency).  CPU-Z displayed the frequency in the taskbar so I could see the relationship.  BIOS contained two options for hardware monitoring - one for the CPU and one for the MoBo.  ASUS documentation was totally inadequate - no clue as to what these are or the implications.  Experimentation showed that the Mobo option was causing the problem so I've disabled the option for Mobo monitoring and left the CPU option enabled.  The CPU option has not kicked in yet. When CPU temp gets too high, TThrotles actions are less severe than letting BIOS cut the frequencly in half.

Now running with TThrottle set for max 66 C and having no problems - but I'm concerned with leaving that Mobo monitoring option disabled.  My old mobo died from unknown causes after less than 3 years, of which the last year and a half were 24/7 crunching.  If it was heat related, I hate to kill another one that way.

Assume the BIOS (AMI 0901 dated July 5, 2011) is looking at a temperature sensor, so I'm asking if Tthrotle can be exanded to cover the Mobo?

No, it's simply too much work to adapt to all kinds of motherboard. Simply too much work for me to handle.

I've been using little utility known as SpeedFan, that has already done "adapting for different mobos" thing. It can usually find and show all the temperature readings that are available on a system and is been enhanced to work with more and more monitoring chips. IIRC, it does have some features to deal with "too high" temps but not necessarily throttling. But at least you can keep an eye on the mobo temp with that.

Thanks, I'll take a look at it.

Fred, I didn't mean to suggest that you develop for all possible motherboards.  I don't know much about the subject, but was assuming that if more boards show up with this feature, maybe the sensors would be similar enough to read them.  I'm sure you don't need different logic for each gpu & cpu make/model, so thought it might be a similar situation.  Anyway, thanks for the time and thoughts.
