One thing I have not seen mentioned. Laptop USB ports are usually only 500ma power output. I have never messed with stick miners are they are pretty much pointless to run but I assume they would like a 2amp USB port versus the low power laptop ports.

This is not a question that can be easily answered. It is really luck of the draw on how long your hardware will last. Of course, running in the proper environment, keeping it clean, etc will prolong its life somewhat but you really are at the mercy of the bitmain chips.

What help are you looking to get? A bad board is a bad board. If you have gone though the basic troubleshooting and its still not working the only option you have is a paid repair service.

The trick is to not run industrial mining equipment at home.

I think its time to do some more research, you have not quite got a handle on how this works.
If you want to mine bitcoin, you DO NOT USE PC HARDWARE EVER. You cannot interface them with a PC, you cant put them on your motherboard.
ASICs come inside miners from Bitmain, Canaan, or Ebang.
If you want to mine ALT coins you can use multiple graphics cards.
There is a ton of information on all of this here on this forum. Do yourself a favor and take a few days to just read and absorb things and then maybe we can help you out.

Phil is 100% right. The trick is to be ready when the new gear comes out or you get left in the dust. I mean even the s7 is still marginally profitable years after its release. The price and difficulty will adjust in a way that keeps things profitable enough to survive when you have current generation miners. You just need to be prepared for the next big hardware revamp/upgrade. The big mistake people make, especially when they start to run larger farms is they dont set aside enough of the profits to do this. Then they are stuck making crumbs once the bulk of the new hardware hits the network.

I agree now that max with this board at current rates you can make 450 USD in a month. It's not worth to build a mining rig which would cost much more than this.
I did calculations on 3 different coins and the lowest amount of profit I saw was $650 and that was at expensive ($0.12) power. Where do you get the 450 number? |

One thing you will want to check on as well is your power supply, the S7 requires 205V+ , where as the S5 runs off a regular 110V circuit. Which makes them a simpler setup.
What the hell are you talking about? Both miners run on 12v power. It is the POWER SUPPLY that you either need 110 or 220 power for, it has nothing at all to do with the miner. |

You just dont understand how this game works. Do a little more research and you will quickly see trying to forecast 12+ months away is a complete waste of time.

Can you post a picture of your cgminer config page?

Last I heard from bitmain they are sold out of S9s until January

I dont know why you would dredge up an old thread for this question.
The answer is NEVER mine on a laptop. You will spend more than you earn and you will destroy your hardware. Laptops were not meant for that 24/7 thrashing that mining gives them

You really should think about getting the 4gb variants, you are limiting what you can mine with those 2gb cards

That should work for an Avalon 741 without issue. I have measured our 741s at 1150w draw from the plug so you are pushing the power supply around 85% of its rating. With a good server PSU there is actually more headroom so you should be just fine. Just remember you need to power it off of 220 to get the full rating out of it. It will not run the Avalon on 110 power.

Like i said the fan speed readout is just a bug, it is operating at its normal speed even though its not reporting it. If this is still under warranty, you would need to send it in for repairs. Since yours is not an autotune im going to guess it is outside the warranty period. In that case you can contact bitmainwarranty about getting that board repaired.

You are pushing that power supply way too hard. Your s9 is using around 1400w. ATX computer power supplies were NEVER meant to run that close to their limits for 24/7/365. Time for a new power supply.

One of your boards is bad, the one on chain 8. It sees no hash rate or temperatures.
Also just so you know your fan isnt actually spinning at 30k rpm, thats a software bug.

It's true unfortunately. I'm getting really tired of it. First it started off as just a couple percentage points. Now it's up to 6%. Time to go back to solo mining. For the past 48-72 hours my hashrate has never gone within 5% of the actual value. Initially, it was share injection (manual or scripted share insertion into the database that was not linked to any user). It would show up on the graphs and I was the only one who had the hashrate to cause that level of spike (30% of the pools total hashrate). I complained, then it stopped and the diminished hashrate started. Of course, no response to my complaint was received. I make up like 90% of the hashrate for the dgb myr-gr pool. No idea what the fuck up is up with this community. There's no honest people anywhere. https://dgbg.suprnova.cc/index.php?page=statistics&action=poolMy hashrate is currently 79,200Mh/s. It will never get close to this number. So if its that bad, why are you STILL mining there? I mean the simple answer is to switch pools rather than write a sob story on a forum. |
