Dear friends ! Some questions are on my mind about the three KNC Jupiter I´m running since a few days.
It would be so great to get any answers / help from you.

Each miners has 4 ASIC boards with each 4 dies shown up.
Right to the dies Voltage and Frequency values, there are tables with DC/DC/V/A/W/Temps.
But the die V/F + tables differ from miner to miner:

- The first one has 0.0000V / 900 Mhz, 8 rows and all fields show values, including core temps.
- The second one has 0.0366V / 750Mhz, 8 rows, all voltage fields show values but there are no core temp values and in 4 of 8 rows A + W fields contain no values.
- The third one has -0.1099V / 750Mhz, 4 rows, V/A/W fields contain data but no core temps.

They all differ in power consuption, board temps and performance.

Now the questions:
1) How can I see the core temp values of two of the miners where they do not show up ?
Is there any special trick or hack letting me do that ?
2) What does it mean when there are 4 or 8 columns ? What does it mean when fields in the tables are empty ?
3) What do the SPI values mean ?
4) Is there any manual for improving the efficiency by changing voltage / frequency values ?
5) Could you recommend any manual for a better understanding what all those values mean and how the boards work ? (for starters)
6) What about the other technical parts on the boards ? They seem to get quiet hot, too... Could it be possible that the miners will burn and spread fire ?

Sorry for all the questions and thank you for any helpful, kind reaction....
Cheers !  Smiley
