Thank you for your experiment kill-switch, it totally matches what I've experienced. Also thanks for posting (maybe re-posting) those concrete values here. Very helpful!  |

Regarding temperature sensor data, I decided to do a simple test...
Dude I've said Bertmod gives VRM temps, as has Uski. Can you clarify regarding NON Bertmod reported temperatures? I imagine they are the same but to not leave margin for doubt here. Thank you. |

BTW... I just ran Bertmod for the first time, It showed all cores on all machines at 100%, except one had 3 cores on a single die...dead... I tightened the screws a bit more on that board... (very tight) It brought them back!!!! Bertmod is awesome! Now 100% on all boards! edit...spoke too soon... they shut off one by one within two mins still...  will try to coax them back.... I'm pretty sure Bertmod didn't do anything to bring your cores back from the dead. Bertmod just expands the stats for the KNC web GUI. |

Non Bertmod is from a separate temp sensor. Can you say where that sensor is located? Even if it was posted before somewhere? Thanks! From kill-switch's phrasing when he mentioned Bertmod ("I have not taken current measurements on my device. Some users using Bertmod...") it seems he was using that "other sensor" then. |

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)

Reporting back on FW 0.98.1 Jupiter 3 with 2 bad dies was hashing at 487 GH/s 20mins in with FW 0.98.1 I'm now hashing at 526 GH/s Still not 550- but I'll take it. Thank you for your report. Anyone tried to upgrade already good miner? I dont know if I have to risk messing it up not me I'm the most confused and biggest coward on this thread...I re-started my miner 2 days ago and now it is running at 568gh and 540gh on slush 5.2 percent error rate and 7770 wu....on version .95..from my noob perspective from what I can tell that is pretty good...I've no idea why it went up like 13gh stable..temp in bsmt the same as is cores etc ..still have top off and fans blowing crossways 5" fans that is both in front of unit... absolutely opposite from what I can tell what phoenix is getting ...it is dry air in Minnesota however and cool again 62F bsmt and he is in Hawaii could humidity have something to do with all this? anyway NOT touching nothing....(I still avert eyes away from unit ..will keep evil jally bfl unit I got on Halloween (appropriate) at other end of the house...lest it jinx it...STILL think I should get voodoo for dummies and chicken entrails as good an explanation as any..in that the unit arrived in trashed box and full of rainwater) so anyway maybe I could get insane GH upgrading to .98.....no balls to do so at this time Searing |
Old Style Legacy Plug & Play BBS System. Get it from www.synchro.net. Updated 1/1/2021. It also works with Windows 10 and likely 11 and allows 16 bit DOS game doors on the same Win 10 Machine in Multi-Node! Five Minute Install! Look it over it uninstalls just as fast, if you simply want to look it over. Freeware! Full BBS System! It is a frigging hoot!:) |

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): 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) |

There is temp data available if the VRM is the 'digital' version, the details are on page 16 of the datasheet. After a close read, it does seem you are indeed correct, that the PMBus will only report two temperature 'flags' OT_WARN and OT_FAULT, not actual temperature data. The location of the lm75 makes sense why it seems to track the DC/DC module (PCB) temperatures better than reporting accurately for the ASIC itself. Exactly. And it also seems that these limits are hardwired into VRM (so no way of lowering them and checking warn flags to get at least approximate temp value). |

Simply because O'rama was just deferring to authority (putting things in the form of "I already said" and "It is"..) without comment to the conflicting experimental results. When experimental results contradict deferment to authority, authority is usually flat out wrong, not just a little bit. Thank you so much dzindra and kill-switch for not only finally settling this but for going through datasheets and what not to give us all this insight into temps! |
