ok, thats over an hour of lost mining... is nobody around?
After down time, it seems that miners don't start always autmaticaly. I have lost 4 hours of mining because the miner did not start automaticaly at power up !

what is a fair shipping price to midwest usa more or less..trying to do the numbers on this ..but with say a corsair 1500i at $449.99 newegg.com and say $150 usd to ship and the $1095 price.that is about around maybe $1694.99 for a 1.7TH unit at 2100 watts .....
It's 1100W, not 2100W! well that would help considerably...let me run those numbers (duh)...off to the calculator again why I post here people can put me in my place (like in the real world....) Searing Geez, just go buy the most popular PSU for mining ever... the EVGA Supernova 1300G2. Newegg has them for $169 after rebate. I have 5 or 6 of them.

Hmm how are you getting such low wattage ? your temps are higer than mine as well. my voltage hovers around 236/239 watts are 1350/1340 my Max voltage is .76 and start is at .66/.66 It seems different ASIC require diffrent amounts of power ? Other than that hash rate hovers around 4510 similar to yours but with a big higher power consumtion it seems.

I have lost 4 hours of mining because the miner did not start automaticaly at power up ! appreciate your response but it seems the FW upgrade has failed and the miner doenst really know what to do. myminer.io works but i cannot access the GUI is the little inset button next to the leds the 'reset' button? Hi Edgar. - "yellow light is blinking 2 times" usually means the miner is up but configured not to mine ("stop mining"). I would recommend finding the miner IP and setting it to mine again. - If it does not start - do factory reset from settings. - If the WebUI not accessible or the miner got no IP - you can do the recovery procedure from the technical blog.

For anyone that doesn´t know:
As far as I can tell, grcooling is a form of immersion cooling, utilizing a "standard" 1-phase cooling liquid.
This is correct, we use an oil based dielectric coolant, which is much more cost effective than a two phase cooling approach. Two phase cooling fluids typically cost about $200 per gallon, while oil based liquid coolants are orders of magnitude cheaper. We can handle rack densities of over 100 KW per rack, with a cooling overhead energy use of about 3%. We can achieve this in any climate on the globe. If you can find me flat level ground, Available Power, communications and a roof, I can build you one of the most efficient, cost effective data centers on the planet. Please see below a link to a youtube video of what our cooling units typically look like in action. https://www.youtube.com/watch?v=6IX9U2zaI_II would be happy to answer any questions. Cheers, Brandon .... So you're saying you're moving the fluid from rack to roof, cooling it to ambient and back to rack for less than 3KW per rack? The path of heat flow through the systems works like this: The heat from the boards/ASICs is tranfered to the rack coolant, which is then pumped to a pump module which houses Redundant pumps, controls, and heat exchangers. The heat exchangers have an oil and a waterside. The waterside of the heat exchangers are plumbed into a warm water loop which runs to a simple evaporative cooling tower, which is the most common & cost effective means for final heat rejection. The whole system has 3 moving parts: 1. Oil/Coolant pump 2. Water pump for Warm Water Loop. 3. Fan on Cooling tower, which may or may not be on due to current weather conditions. 3-4 KW is a typical energy cooling usage for a 100 KW system.

Well, I ordered myself an SP20. I've never had an issue with ROI in the past so happy to cough up some coin for an efficient miner. At what energy costs? $.15 Let's just say there are always new coins to mine other than BTC...just gotta be smart...

you can get a 1200W GOLD PSU for under $200, not sure why you would use the most expensive 1500W possible in your example I think that question is answered by looking at all of his posts... He's obviously here to cause drama given he's obviously not interested in the products.

Hopefully zvisha or someone from support will arrange with you to remote access to your device and sort it out, I could be wrong but I don't think you will get much help from most of the enthusiasts on the forum, not for want of trying but more for lack of technical insight.

Please answer the following: - when doing recovery, do you get the leds going green-yellow-green-yellow...? - Are you sure you are trying to connect from the same subnet as where your miner is? - Do you get the led blinking twice after doing recovery? I think your miner changed IP, but myminer.io for some reason does not reflect it. Go to your router UI and try to see what is the miner IP (see all the IPs and try to connect to each).

It's not that strange, it's our server that gets overloaded lately. We will fix it next week. In recent FWs you have option to update from your host so you can upload latest image (For SP30 it's here:http://storage.googleapis.com/spond_firmware/spon_2.3.46.tar) from your host. Keep your FW updated to latest version (not the "testing" ones) to get most stability and hash rate. Regards`

Hmm how are you getting such low wattage ?
your temps are higer than mine as well.
my voltage hovers around 236/239 watts are 1350/1340
my Max voltage is .76 and start is at .66/.66
It seems different ASIC require different amounts of power ? Other than that hash rate hovers around 4510 similar to yours but with a big higher power consumption it seems.
The max watts were set up @ startup when the unit does test the power supplies. I did not do any manual overclocking. The values you see there are the hard limits in PSU output set by the software. When it was higher (over 1300) at startup, the ASICS were overheating .. I have some logs with most of them at 105 deg C. now only one/two arbitrarily get there, and only temporary. The first unit balanced itself .. after that I did the upgrade to 2.3.30. with no major changes in power and hashrate. The (-50Gh/s) change in hashrate came after deploying the latest firmware. I don't care about losing 50Gh/s if the unit is more stable.

I was also playing with the stats .. trying to balance them out and include the beagle CPU LOAD there .. Zvisha, did you have time to review my pull request on GitHub regarding the minepeon UI ? Some more files need minor updates, but I'm happy now that my lighttpd.error file is not growing any more.

reluctant to try .43 again
36xxGH sucks but better than zero!!
e2a - successfully upgraded to .40 - 45xxGH
If you install .43 FW and you get the yellow led try booting the miner without the LAN cable and plugging it back in ~3 mins.

For anyone that doesn´t know:
As far as I can tell, grcooling is a form of immersion cooling, utilizing a "standard" 1-phase cooling liquid.
This is correct, we use an oil based dielectric coolant, which is much more cost effective than a two phase cooling approach. Two phase cooling fluids typically cost about $200 per gallon, while oil based liquid coolants are orders of magnitude cheaper. We can handle rack densities of over 100 KW per rack, with a cooling overhead energy use of about 3%. We can achieve this in any climate on the globe. If you can find me flat level ground, Available Power, communications and a roof, I can build you one of the most efficient, cost effective data centers on the planet. Please see below a link to a youtube video of what our cooling units typically look like in action. https://www.youtube.com/watch?v=6IX9U2zaI_II would be happy to answer any questions. Cheers, Brandon .... So you're saying you're moving the fluid from rack to roof, cooling it to ambient and back to rack for less than 3KW per rack? The path of heat flow through the systems works like this: The heat from the boards/ASICs is tranfered to the rack coolant, which is then pumped to a pump module which houses Redundant pumps, controls, and heat exchangers. The heat exchangers have an oil and a waterside. The waterside of the heat exchangers are plumbed into a warm water loop which runs to a simple evaporative cooling tower, which is the most common & cost effective means for final heat rejection. The whole system has 3 moving parts: 1. Oil/Coolant pump 2. Water pump for Warm Water Loop. 3. Fan on Cooling tower, which may or may not be on due to current weather conditions. 3-4 KW is a typical energy cooling usage for a 100 KW system. What is your estimated cooling infrastructure $/W for high density hardware like an SP30? Your site says $1/w but I'm assuming that's not right because that's about twice as expensive as 2 phase immersion cooling.
