so again payments are stuck.
I got my payment, but it seem to be 10-15% short like usual. Not sure what is going on. *shrug* |

On one s5 I have the s3+ heat sinks, better thermal compound, 2 fans on it and clock it at 337.5. It still pulls 1,100+ Ghs at a little less wattage and runs a tad cooler, at the time of writing this the boards are 44/45C with the fans locked at 40% in 70F ambient. I can run the fans slower and get the temps up to 60-65 and it will be about s3 loud. 3100 RPM current fan speed
Given a choice between replacing heatsinks and adding another fan, i think the additional fan sounds easier. How do you attach a second fan? at the opposite end to the original I'm assuming to 'pull' rather than 'push' the air. How do you supply power? is it able to be 'plugged' into the S5 controller board? Replacing heatsinks, with the associated detaching of the originals, the adhesive etc...water cooling then becomes an option, as the complicated/tricky bit of attaching the 'sinks seems to be the same. Crash EDIT: Meanwhile, i'll drop the frequency to 337.5 and see how things go. You add the fan the same way the first one is in, correct, just to pull or push instead of push or pull to keep the airflow going. So both fan will have the same orientation. There are two 4 pin fan connectors so you just plug it right in. |

Your gear reminds me when I had a bunch of KNC Jupiter laying around. They were running perfect and smooth and nobody wanted to buy them at all. I think I ended up selling 2TH/s worth for only like $150 CAD. And I was actually glad that finally someone took it who had free electricity. Old gear like this is almost impossible to sell.
Updated title with the price per GH/s, maybe it'll make some people aware of how good of a deal this is. Cheers. |

So I have my first mining rig up and running, working hard and doing better than 'advertised': One S5 averaging just on 1200Gh/s.
I have a question on temperature though. The S5 seems to be running quite hot at 65-70 degrees C. It hasn't gotten to the cut-out of 80C yet, but I'm interested in options to reduce the heat, and what effect the heat has on efficiency.
Unfortunately due to the noise, the miner is under the house, which is not secure, and so in a locked box bolted to the wall. There seems to be plenty of vents, and I have an extra exhaust fan on the box, also I have removed the plastic sides of the S5.
Crash
You should not remove the plastic sides, they are needed to direct the air over the back of the circuit board. I would also be suspicious of the size & number of vents in the Box. Have you tested the miner out of the Box to see how much the box adding to the overall temperature? Rich Before placing in the box, the miner was operating at 50-55, so there is an increase in temperature; not that it was cool in the first place. Removing the sides has lowered the temp from 70-75 down to 60-70 (61&66 right now) so it has helped. Probably would need the sides if I had a stack of the miners right next to each other though. Crash The problem i had with doing that myself is that i had cooler air blowing on the sensor, so the temps showed way lower. But the temp sensor is not the chips temp, its just a sensor on the board, so while it showed 50C, the chips at the end were over 80C. So if you can, double check that this is not happening to you. |

do you still have any S5's ?
I did not sell any, yet. If i can get a price that make it worth me selling them, i will. |

G'day,
So I have my first mining rig up and running, working hard and doing better than 'advertised': One S5 averaging just on 1200Gh/s.
Loving the new topic to learn more and more about, but just a hobby for me.
I have a question on temperature though. The S5 seems to be running quite hot at 65-70 degrees C. It hasn't gotten to the cut-out of 80C yet, but I'm interested in options to reduce the heat, and what effect the heat has on efficiency.
Unfortunately due to the noise, the miner is under the house, which is not secure, and so in a locked box bolted to the wall. There seems to be plenty of vents, and I have an extra exhaust fan on the box, also I have removed the plastic sides of the S5.
Is water cooling a realistic option?
When (if) I get a second rig, the heat will become a real issue to resolve.
Thanks for any advice
Crash
Yeah, you need air flow, you can't just dump a miner in a closed environment. Get a cheap acoustic panel, build a tunnel around it, open the window, or dump the heat outside or something. Some people use those vinyl tubes to dumb the heat outside or into their central house heating. And water cooling a S5 is possible but its not worth it considering it does not return that much BTC anymore. |

How old is your stove? From the 1970s? Because most modern stoves have outlets which make it convenient to plug a toaster or microwave in.
Yeah, it even has the green tint lime color everyone was so excited about at that time. ...tldr it doesn't have outlets. |

If it is possible to overload antmayner if the speed falls below a certain level? Thank you.
I'm not sure this is pertaining to cryptoGlance... but what are you asking exactly? Your sentence does not make much sense. |

Got my 2 server PSUs today, thanks Virosa.  Cheers! The tubes are no longer running, so they're just idling, now. Sound like a waste, so if you're looking for 2.3TH/s~ for rather cheap, let me know, thanks. Could give a discount if you buy some S5's too. -0.80BTC for all;
AMTube (3 Total), including 3 controller, incl Shipped within Canada, elsewhere is small extra
All boards work (12 of them), one miner has 8%ish less hashrate because of 2 boards slightly slower.
Dropped price to 0.75 BTCYour gear reminds me when I had a bunch of KNC Jupiter laying around. They were running perfect and smooth and nobody wanted to buy them at all. I think I ended up selling 2TH/s worth for only like $150 CAD. And I was actually glad that finally someone took it who had free electricity. Old gear like this is almost impossible to sell. Yeah, its a waste, considering the price i'm selling them at, if you have free electricity this is several time better than buying S5/S7. I'm talking about like .12 cents per GH/s here and these run great at Kano now, with the proxy thing. I'm moving soon so i would not mind selling some stuff to simplify, but if i don't sell them by now i guess i can just setup 240v there and run everything myself on free electricity. The only reason i am offering these for sales is because right now i'm stuck on 120v and it doesnt take long to cap an apartment grid on 120v. What about plugging them into your stove? Each stove has 2 15A 120V outlets. Or if you don't use the stove just use the 240V outlet, can get up to 50A out of that. My stove does not have any outlet, that would be pretty dope. And yeah its on a 50A breaker. The reason i did not buy hardware to exploit that is because i'm not certain what i will need once i move. The other problem is i would need some ultra mega long power extention cords to bring all that current to my living room window to dumb the heat outside. |

I have a Antminer S5 coming in the Mail, my only concern is power. I'm looking at the CORSAIR CX series CX600 600W ATX12V v2.3 80 PLUS BRONZE Certified Active PFC Power Supply. (sold from NewEgg) Since the power supply is a 600 Watt, and the Antminer pulls 590 Watts will the 10W gap be enough for the Antminer, or will it fluctuate a lot?
Any Suggestions?
Thanks,
Landon
It would be enough, the gap is not 10W, since the rated Wattage is for DC, not AC. 590w is the "At the wall" = AC. But that PSU is not very efficient and its not bad at all, but not great either. I'd go for a 650 EVGA G2 at least. Definitively worth the price difference imo. Great warranty, not that you'll need to use it, most likely. (I never had to and i got quite a few EVGAs.) |

There is no fix, get used to it and learn to spot those ratings when judging others for trades.
Figured as much, shitty that people like this can continue to abuse their privileges like this. Thanks for the input. Don,t worry about it, he is super red trust, so his negative report is not counted toward your trust rating #... and if people look at your trust history, they will see the guy calling you a scammer is a super red trust, which means absolutely nothing. I've had such users leave red feedbacks on my profile you can go check yourself, it did not prevent me from building trusts as you can see. |

You state your best OC setting is 393.75, but the chart shows that 387.50 does more TH/s and less electricity used?, doesn't it?
They are 10 mins runs as labeled, so not super accurate. 393.75 does 1.3 after the hashrate average out properly. I have a single unit that does 400 for 1.32. That review was based on my first S5, now i got a couple and i been running them for months. I use EVGA ATX PSU and at their voltage, 393.75 is the best. One of them takes 400 without a hitch. They're possibly for sale, too. |

This should really not be needed. The avalon firmware does not come with a wlan interface pre configured but we know for a fact Open WRT can handle it. So it might just be a matter of downloading the right package to install on Open WRT. Someone that knows networking a bit should be able to give simple instruction on how to get this working. |

What kind of power supplies are you using?
3 IBM 2880 PSU with Jabberwock mods The batch 7 uses: 1278 W (at the wall, with APW3, 93% efficiency, 25C ambient temp) The batch 8 uses: 1293W + 10% (at the wall, with APW3, 93% efficiency, 25C ambient temp) I'm pretty sure the batch 7 numbers are off, but with these numbers we're at 2571W per PSU for a platinum rated PSU. I've been running these miners since the middle of december with no problem... until now. The batch 8 uses: 1422W, 1293 + 129 (10%). Our results are a little higher than this. Total watts used: 2700, if the numbers posted by Bitmain are correct. Updating the firmware is always a good idea, read the change logs and see what others have experienced first. But will the B7's work on their own not alongside the B8's? My B8 use 1415W at the wall, so that sound like accurate to me. I don't know if all B8 are the same, some people say it varies, which i doubt. Why would you recommend people to update the firmware when there is no feature difference? They risk putting the wrong one and bricking their controllers for nothing. |

Ok, got it up running and so far it is stable. I am running UC at 543 instead of stock 700 so there's a drop in power need there for sure. Looking at how the lepa has 6 output sockets assigned to 4 30A rails is a bit strange and if I wasn't running UC I'd wonder if this unit could handle it based on how the rails are, obviously, doubled up on some of the outputs...
Probably going to return this rube Goldberg designed psu and go with a better unit. But so far it's running ok, no smoke or any bad smells (yet)!!
The unit is fine, it can run an S7 full speed. The fact its multi rail is annoying but you should have no problem if you do something like 3 individual rails on double and then split a 4th in the 3 blades. Running it at half load is not necessary. |

I've received my payment correctly, but I'm still missing around 0.01 from when the bot changed.
Please send me a PM and I'll tend to it immediately. I forwarded you one of the PM Bitcoin boy requested from me, as i never got a reply from him. I received a manual payout of 150 posts, when i was had at least 236 unpaid posts. Considering these posts were accumulated over 4 weeks of missed payouts (in which i received 2 late partial payouts), the manual payout being capped at 150 posts seemed like a minor mistake as well. 86+ missing is not as much of a big deal as the 400+ unpaid posts i had at some point, but it would still be cool. Thanks. If it would make things simpler, i would not mind switching to a flat rate. |

Hahh, thats pretty cool. I think we'll get in the 10 Exa long before this get puts into practice. At least in practice that would work for us miners. We don't know exactly what it could do for us, but also, any early tech tends to be extremely costly to manufacture, when its ready. |
