Nice build on the Mining Power dude Grin

Well if u i need of o good config for thoose i could maybe Help u Wink

I get my antminer u3 gopign with 70 gh/s at wall 60 watt with an different config then the standart.

if ur interested iam willing to send u the github source via Pm-

lama-hunter

Thank you very much

no question so far but I would be glad to receive a comment or 2 in case there is something wrong or whatsoever.

yes it is protected from all of that. Keeping my S5 in my basement as heater too.

It will be secure with a lock and soon a camera. ( theft... )

What do you have in mind Virosa ? I'm curious.

Nothing really, per your OP, since we both live in the great Poutine empire, criss, we have an electricity rate that make upscalling our home farms quite attractive/addictive, for me anyways. So if you had a few question then(about only 1-2 miners), maybe you'll have a few question later on. (10+miners)

I think the thing that would make the biggest difference for my operation is switching to 220/240v. But seem kind of a pain to do it temporarily in an apartment i'm not supposed to be doing this in the first place. (Changing stuff)

I dont have questions honesly I know how its working. I was thinking that you had some business offer or whatever Tongue

So the job is done, Ill post picture tomorrow... Mining is much a passion to me

hahahhahahha....totally true Wink

well if I can make one or 2 miner work on the same network...adding a few mores wont be a problem afterwhile.

About the voltage setting I cant argument about that, I dont know hows that work. I just can say if you have a good relationship with your owner, there is probably something you can do. I'm myself renting my owner shed for a little 10 CAD / month.

We will see.

My S4 is now chilling outside, protected in a shed, ill upload pictures later.

Nice temp.

Very much so, if your miner is protected from having water thrown on it during storms with high wind speeds, then this is a pretty good setup.

Look like you got everything covered now, if you think of doing more than just expanding from there and need to bounce off some ideas, let me know.

Quebec, I just checked the power cost and it is ;

First 30 daily KwH = 0,0557 $ CAD / KwH
Then 0,0826 $ CAD / KwH

Nah I just want to find a way to full underclock my frequencies and then lower fan speed for when i go to sleep instead of turning it down and preserve the temp lower than 70.. dont worry i know i have to stay under 70 and to not go higher than 73v for the fragile s4 power supply

thx for link.

No problem, but having to reflash the SD card when you go to bed and then when you wake up does like a pain. Sad

And i said 70c for the S5 (actually under 60C is recommended for slower hardware deterioration), but the S4 can have problems with low 60c. Start dropping chips, crash. I've had issues before my S4 reached 70c, i never reached 70c on them, they would crash or drop 3/4th of their chips.

I'm guessing the sensors are not placed where the board get hot.

Cant say about that, at least i have the replaced power supply by bitmain, it should help. And yeah lol it seems a pain i think ill just reduce the frequencies and always check to keep my temp around 60-70.

How may I setup a custom firmware?

Ill check the temp carefully at that moment.

Thank you very much by taking your time to answer, greatly appreciated.

Its not a moment thing, you're already at the limit and you're talking about raising the temps by 20c.

Anyways, its here;

Update, what do you think about those stats ?

I'll answer to the question you asked me too;

First the S5 look awesome. Try to keep the temps under 70C and there should be no problem.

For S4, you need to setup custom firmware both for the fan and the volt. You can change the value but it wont actually be applied.
For the fan, looking at your temps, its too hot for you to make the jump to the custom low fan firmware.

I did not try any aftermarket fans for the S4's, i've tried S1's fan in them tho, it work and is very quiet. (But not cooler at all)

However Bitmain posted this back then;
https://bitmain.zendesk.com/hc/en-us/articles/204199879-Antminer-S4-fan-specification-and-possible-replacement-fans

Maybe some people actually tried some and can tell if they are both cooler AND quieter.

I heard the Scythe Ultra Kaze is good for the S5, dunno bout the S4.

Nice setup! I'm jealous of your cheap power. I'm guessing you live in Quebec with those prices.

I'm just across the river in Ontario and I pay over twice as much. Sad

Seriously ? ouch... Still, when we go further than the minimum threshold it cost 0.10$ kwh....Anyway, I dont use my basement heater and cloth dryer so I dont really see differences.

I have a few questions now.

Are my settings ok ?
Would you overclock the S5 a little bit more ?
If I underclock, should I lower the voltage of the S4 manually, and if thats the case, which is there any voltage shart somewhere?

From now on I like a lot my Bitcoin Mining experience, any other canadian fellow out there? Wink

I am from Canada~

The free heat/cooling is pretty nice, i use low fan speed on both miners to cut on the noise.

Anyways, if you setup custom firmware on the S4 you could change the voltage, but otherwise the volt thing won't actually be applied. Apparently old S4 that were not updated still have working Volt control, it was only removed later on.

Personally i don't trust the S4 stock PSU, many people had a problem with it, so i would not overclock it further than 212, personally i run 200 or 206 and i set the volt to 0670 or 0710. I'm just being extra careful here, but since my limitation now is more watt capacity at home, i preferred to run them undervolted at 200mhz and just run extra S1's (amazing little heaters that run 100% silent and can be placed anywhere

).

For the S5 however, you could certainly overclock some. I run all mine at 393(1.29~1.3TH/s), except one that run 400(1.32TH/s+).

For S5 noise, i now run the fan at their minimum speed (2400RPM~) and just feed outdoor air to them and having 2 fans on them really help the cooling, its insane.

Thank you very much for your answer.

How are you able to control fan speed ? I searched around a bit and didnt discover anything about that except by adding a heatsink on a chip. Can you tell me more ?

Allright I wont go more than 212.5 for my S4 and will check that out. volt will stay at 72 since i readed about the s4 power supply problem.

I'll test out a better frequency for my S5 since I have a 800 watt power supply and stocked S5 are 590.

Do you know somewhere I could buy better fan for bitcoin too ? In case I want more quiet stuff if running low speed on stock fans is not enough?

Everything looks good. Glad you're taking advantage of mining with low $/kWh for heating as well.

Thank you very much. Do you think I could overclock a bit more ?

Should probably have your miner ran over in our side. Maybe a friend with a garage? You pay the electricity, they get free heat? Anyways.

I'm wondering if its possible to get industrial electricity rate in a small office or such. That would cut the electricity cost by almost another half and you dont have to hear the noise. Keep the quiet miner at home during winter for generating free heat + BTC.

We're going to need a bigger heatsink.

Antminer S4 - Antminer S5

1 Antminer S4 - Bitmain Stock PSU
1 Antminer S5 - 800w/1000w PSU with 4x soldered PCI-E plugs (14AWG Cables) (Server-grade HP DPS-800GBA)

Mining on Antpool.

0.06 $ CAD / KwH or 0.045 $ USD / KwH

Using the miners in my basement where there is 2 rooms. Miners are used as electric heaters to heat both rooms.

Maybe Ill replace my cloth dryers and help growing some marijuana plants using fans and heat power, expecting a better use of my miners to achieve a better roi.

Frenquency used ;

S4 - 212.5M, 0720 V
S5 - 375M

Max temp recorded so far ; 60°

Hashing Average speed ;

S4 - 2,115 GH/s
S5 - 1,215 GH/s
Total = 3,330 GH/s

S4 ;

S5 ;

I have a few questions now.

Are my settings ok ?

Edit ; Antminer S4 Frequency now at 218.75 and 0.725 V
Antminer S5 at 425 Frequency

About 3,585 GH/s now
