just confirming, yes.
But also good to know the temp sensor readings are from a different location on bertmod than the normal firmware... perhaps the Bertmod Dev could add the asic temp, or KNC could add vrm temps....

Based on the vrm info.. I'm trying a few things.... details later.

Both normal firmware and bertmod are using data from lm75 temp sensors (chip in red circle in the picture below). One sensor is on each mining board and one is on controller board. Differences are probably caused by refresh rate of the temp data. Stock firmware refreshes data each minute, stores them to /var/run/stats.knc and displays this file. Bertmod refreshes when requested.

Unfortunately, there is no way how to get temperature from VRMs (or at least I did not found it in datasheet)

thanks...
guess FeedBackLoop may be right!, right?

Yes, temperature readings are measured by the same sensors but timing is critical here. You can have slightly different readings each time you measure temperature.

If you are interested and want a proof, ssh into your box, open /sbin/monitordcdc, read through it and look for following line (present at line 42 in 0.98):

Code:

temp1=$(i2cget -y $bus 0x48 0 w 2>/dev/null)

This line reads two bytes from miner board temp sensor. You can find same command being issued in asic_status.pl (bertmod0.3, line 37)
