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.

I'm quite sure he meant Bertmod was great for showing the bad cores.

Ah, ok.  I misunderstood the comment.  Thanks for the correction.

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.

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.

Non Bertmod is from a separate temp sensor.

ok, so what's the verdict here?  I'm just wondering ...  
Why you think O'rama is wrong?...
Your experiment results, or info from Bertmod DEV?

just confirming, yes.

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)

guess FeedBackLoop may be right!, right?

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

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)

Awesome!  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).

Why you think O'rama is wrong?...

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!

You are welcome I have been digging in my miner since it arrived and finally I can put the gained knowledge to good use

Not a mod, a repair of a missing or bust DC/DC.

Looks like someone attempted a 'fix' for a bad DC/DC module.  Is it even possible to repair?

[FarSky7]

according to the poster it works.

There's two temp sensors one is in the VRM itself, but some boards have an analogue DCDC which is why they may not show every statistic.

Uski brought this up the other day as well in this thread, and here post#65;

http://forum.kncminer.com/forum/main-category/main-forum/6183-bertmod-0-2-unofficial-firmware-mod-feedback-thread/page5

The reason you haven't had much of a comment from me is the only time time I have to check this thread currently is via cursory glances whilst on public transport, and even then the reception and a tiny mobile screen isn't favourable.

I wouldn't put solder to your boards if you value warranty btw.

In that post Uski is referring to the Amps, voltages and ON/OFF statuses that the digital DC/DC modules output. Not temperatures. Like you say they likely have a temperature sensor but that's likely only for the flags kill-switch mentioned.

Notice that in some of the screenshots people post of Bertmod, one can see the temperature sensor information but no DC/DC detected (certainly the analog ones like you say).  

I understand it might be hard to give anything other than the straight answers you believe in while keeping track in a phone. Sorry about complaining about deferment to authority. There is quite a bit of that here nonetheless and I feel I got dragged into this collective temperature sensor discussion/investigation. But do tell us about your conditions now. Will you be employed by KNC? Staying in Sweden for the November batch? Will you get a place to sit rather than your phone?

Okay, I'm done fiddling..  This is 0.98 with enablecores again
heatsink fans on stock regular way, nothing else.



Funny thing is, the Saturn with the 3 disabled cores is the fastest, and has the lowest error rate...
I'm thinking these speeds are about as good as it gets without overclocking.

case open? case closed?

open, stacked

Q: Has anyone tried the bfgminer on eligius?
any difference?...stable?
able to set intensity?

Smart man!  I have a feeling that some of these guys who can't stop experimenting with their gear are going to be very sorry when their miners have meltdown.
