Title: KNC Miner - temperature controller - solves problem with DIE off Post by: mzahor on February 13, 2014, 04:09:40 PM Hi Guys,
I've created MCU controlled temperature regulator. Controller adjusts fan speed to achieve target (selected) ASIC temperature. It resolves issue with "DIE off" problem ( some DIEs need higher temperature ). Howto connect sensors: https://vimeo.com/83987115 (https://vimeo.com/83987115) Howto setup: http://youtu.be/WT6SBwGRemU (http://youtu.be/WT6SBwGRemU) http://farm3.staticflickr.com/2817/12480793495_3a29c8ed1a.jpg http://farm4.staticflickr.com/3738/11911240385_bd471f0e5d.jpghttp://farm3.staticflickr.com/2844/11911693174_9872cd3e39.jpghttp://farm6.staticflickr.com/5537/11911239795_56f4e01d7d.jpg 3 sensors version - 95 EUR [ or BTC eqiv. ] - you can control 3 modules [ chosen hardware is unable to handle more then 3 sensors + fan control ] If you are interested: mzahor@dtech.sk Title: Re: KNC Miner - temperature controller - solves problem with DIE off Post by: joeventura on February 13, 2014, 04:14:51 PM looks like a great solution but there is no guarantee it would fix the problem and the cost is probably 5 times the revenue a resurrected die would make.
Title: Re: KNC Miner - temperature controller - solves problem with DIE off Post by: mzahor on February 13, 2014, 04:53:21 PM It depends on how many DIEs are off.
Title: Re: KNC Miner - temperature controller - solves problem with DIE off Post by: DPoS on February 15, 2014, 07:43:56 PM Good idea but there's nothing scientific yet on bringing back dies. I would be a customer since I do have three boards with a die off but I have to do some tinkering with each one to see if they are fixable

One can try heating up ASCI by covering fan or disconnecting it ( ASIC FAN )- if it will lead to start the DIE than controller is solution
