Found it. Its resistor R55 in the photo.
What is a safe voltage to try? 0.850V or so ?
Max voltage is 1.2V, but yes I would go for 0.85V then take the frequency up in steps checking for HW errors and keeping an eye on the temperature. Will have a look for the Data sheet later. Rich There is only one website that sells those IC chips and its in Chinese. And I can't find the datasheet on it. |

Volterra were acquired by Maxim back in 2103 so may be making it more difficult to find? Rich |

Hi guys I need help, I recently bought 2 antminer s3+'s on ebay, They were both working great for about 1-2 days, now 1 of them on the miner status page, chain #2 is not there, and it's only running 230~ GH/s instead of 450+ like it was before. Is this something I might be able to fix or should I contact the seller?
edit: I'm running 2 power connectors on them, I switched both connectors from the 2 that was plugged in to the other 2 and now it's running full blast again, Is something wrong with the miner where the power connects to one side?

I've always used all 4 plugs, I figured they are there for a reason.
You can't just connect to one side, then the other board is not getting any power.
When chips X out you can typically power off and then back on and they come back, but if you're losing a whole chain it's something else. Do you have a psu with 4 pci-e cables you can use, or a second psu with 2 more cables? What is the power rating of your psu?

Im looking into buying a used s3 can anyone give me a recommendation on a trusted reseller? I dont want to end up with one thats broken. And for a power supply i was going to go with a cx850m so i can run a second s3 on the same supply that will work to power 2 s3 units correct?

while an 850W PSU can power 2 S3s at stock speed you have to get one with 4 SEPARATE PCI-E cables.. (not sure about that model but id check, the picture shows it only have 2 cables with 2 ends each) i would not use cables that have 2 ends to power a S3 by itself.. also the s3 is really close to its end of life.. if you dont have absolutely free power, id consider getting a s5 instead.. edit.. its also a bronze psu and you want a gold or platinum one.. so id pass on that PSU.. |

The S3 is relatively cheap and i cant afford an s5. I was going to go with that to start collecting bitcoins and hopefully have enough in about a year to get an s7 or whatever the newer miner model is. electric is about 9 cents where i live. can you give me a specific recommendation on psu? Pci express is 3x2 correct? If so it does have 2. Right now im running a u3. the main thing i want to do is test the waters without diving in head first. With the u3 im basically paying over the current btc price in electric and im only getting about 10 cents worth of btc in a day. |

If i have 2 running for about a year and i consider electricity a write off and save all my bitcoins do you think ill have enough in about a year for a s7 or whatever the new model is? Right now on bitmaintech the s7 is listed as 4 btc.

probably not.. you would be lucky to have 1 btc saved up by years end.. 2 s5s maybe.. but like i said, in july the block halfs.. so they will make half as much as they do now.. probably even less due to difficulty going up. it would really only be a good deal if you got the s3s for free and you already have a power supply to run them.. even then you will lose money in the end. you would do better if you just put your change in a jar and didnt spend it for a year.. |

The simple answer is no you won't have enough BTC to buy the latest and best by running 2 S3's for a year UNLESS you solo mine and find a block (which itself is a lottery no end). |

Keep saving ... keep an eye on the bitmain site .... keep an eye on the BTC / USD rate .... it won't be many months before you can buy the latest. BUT before buying, read this forum for user experience on the miner you want to buy. |

I didn't want to buy one with bitcoins I was trying to buy with USD. I have had difficulty buying bitcoins in the past. How should I go about buying btc?

It may favour you, at times, to buy in USD rather than BTC and the reverse is also true (that most times), but that is why I said to keep an eye on the BTC / USD rate. Buying BTC ... depends where you are but there are many exchanges AND individuals selling BTC. Make your choice and do your due dilligence! |

If you saved the money in electricity you spent running two S3s for a year you would have more money than the bitcoin they are able to generate in pooled mining. |

Hi to all
Just switched my ISP from totally unlimited (but very slow) to 150Gb per month (but quickish) 4G internet. I am hosting an S3 in my bedsit which actually is a nice little 400W heater now the nights are getting cooler here in Portugal. The question I can't seem to find an answer too is how much bandwidth does an S3 use in a 24 hour period? (up and down) I have Networx installed on my desktop and laptop which gauges the usage from computers but the S3 is connected directly to my 4G router so bypasses the monitoring.
Any help much appreciated. TIA

Have never measured it but what I have read is that using Stratum with variable difficulty requires ~1kbps (0.125 KB/sec). This is regardless of the speed of your Miner.

Hooked up 3 ant s3 to a 1gb/mth data plan once and it chewed 533MB over that period. so about 180mb/mth or so each I presume. Hi to all

Hello there,
does someone has an Idea why my S3 don't "accept" the changes at the asic freq file?
It does save the file correctly but after reboot it still comes up with the "standard" freq of 225^^allthough 225 is comment out and 218,75 is "active".
It doesn't matter which freq I activate, it always comes up with 225M.
TQ
