    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 tovar/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)




    Hmmm, so the temperature is measured on the outside of the plastic bags and cardboard that some are using to warm their chips?

    Why do I smell burning ASICs?  Lol.

    any jupiter owners running .98 notice that the hashrate is highest when you do a poweroff cycle and reboot, it will hit 565-575gh/s at the pool and then after running for a while the pool listed hash rate will get progressively lower, i dip at 490gh/s

    any idea why this is?



    This is exactly what happens to mine, maybe even lower, 470, 460... no idea why  Huh
    did you ever try 70-75C? after enablecores, on 0.98?

    24 hours later.. my 3 sats are 850 at the pool on 12 hour average!
    that's 283 each, which is exactly what they show on cgminer!

    what are your temp readings? how are your fans/case set up? im thinking of following you, doing enable core, and rebooting and then putting case on upside down to raise the temps a bit and see if i still get a down slide in hashes over time with higher temps.


    at the moment, all 6 boards(3 sats) are between 69-73C, no case fans whatsoever, heatsink fans only. cases off, stacked, with cardboard partially blocking the fans airflow into the heatsink, like this...

    All running 0.98 with enablecores over top
    this is for night-time basically, because it gets downright chilly in here.
    During the day, I can remove the cardboard, and they stay around 70
    Ive tried several times to leave them off... but if they drop below those
    temps by more than about 5 degrees, I see a drop in my rates, and can
    see one one miner loose about 6 cores, and another loose two...
    then they take forever to come back, like 6-8 hours!
    I have one miner that is super-rock solid, one a tad finicky,
    and one super-sensitive finicky, don't breathe near me kind
    Also, It may just be my imagination, but they seem to work better
    while its raining outside(high humidity)

    thanks for sharing, phoenix!
    i can confirm that after putting my case on entirely and raising the temp by about 8-9 degrees my hashrate has remain steady back in the 550-570gh/s on btcguild pool readings.
     
    if i've helped you, donations welcome: 1BwGnrqSjbfJ39mTNrvb257eUSuUP7Pfxh

    Well according to the genesis block calculator http://mining.thegenesisblock.com/   difficulty has gone up 950% in the last 90 days. This does not bode well.....almost 500% the last 60 days...

    just hope we don't see a "toboggan run" down this steep slope when everyone xfers their BTC to USD in a panic to get ROI back. Myself I'm so far in the hole with the BFL scam...I'm just gonna ride it out ...so at least I get a good story out of the whole thing.....'Well back when I was young and full of p*ss and vinegar and thought I was smart.....(you can guess how the rest goes) ....

    fun ride...making good time....what could possibly go wrong right?

    That is how the discussion started when I warned FiatKiller about it.  Smiley

    But trusting Phoenix's values, the chips should hold a lot more than the VRMs.

    Actually I think Phoenix's method is more dangerous than mine because he is blocking the lower portion of the heatsink. I am blocking the top i.e. further away from the chip. The purpose of a heatsink to draw and dissipate heat away. My method allows the heat to be drawn away where it counts most and as long as the IR temp gun confirms 140F or below on the top of the chip it is probably quite safe. System still running like a champ at 269 hashrate after days. It is not that odd to not have a fan on the heatsink because in the old days even the CPU did not have a heatsink. First they added heatsinks and then heatsinks with fans. The only goal is prevent overtemp of the chip. Oh, and I do work in engineering/IT. Designed software, hardware, tools etc. over the years. Just have not done much with Linux. I love it when people tell me "you can't do that" because I've proven them wrong more than once like when I wrote a program to default the password at the hex level in a program used in many police stations. The cops kept forgetting their password especially because it made you change it every so often.

    Also noticed that. Although the back of the heatsinks are still completely free to radiate in his setup and the fans are blowing.

    Would you mind about posting the link to the previous post containing those details, please ?
    Thanks.

    edit:
    * as far as I can remember the post did not contain such things, just the 'how to'

    **maybe I do mix this up with another guy playing around and posting quite similar pics ?
    I can remember some electrical resistance I do not see on those pics

    I do not speak of replacing the module dc dc is very complicated. The module in my saturn was not broken. A protective resistor is the one that was burned. I have encontado that breakdown in my Saturn and then put a new one is running at 100%.

    Quitando el estaño con el Flux de soldar
    Removing the tin welding Flux

    Yo des soldé el condensador por equivocación y además lo perdí. Yo  he puesto uno de sustitución de un valor arbitrario,  no creo que sea un valor crítico. El condensador es un condensador de  desacoplo. La resistencia es de 1 ohmio 1% de tolerancia. Yo supongo que esta resistencia es un fusible para proteger el circuito (corto circuito). Si esto fuera cierto se podría puentear solo que el circuito estaría sin protección (no me he atrevido ha hacerlo).

    I soldered the capacitor des plus accidentally missed it. I have put one of substituting an arbitrary value. I do not think it's a critical value. The capacitor is a decoupling capacitor. The resistance is 1 ohm 1% tolerance. I guess that this resistance is a fuse to protect the circuit (short circuit).

    I meant to say he replaced a mal-functioning/missing component, that it was not a mod to help. Yeah, resistance is probably a lot easier to change than a DC/DC. Good job nonetheless Amolina and thanks for sharing.

    Your "promising sound currency" is just that, a promise which did not became reality (yet?), while your "exponentially-printed-to-oblivion/give-inflation-to-bankers-enslave-everyone-else/no-control-over-your-money corrupt currency" is what everyone in all civilized nations use to pay their debts.
