Downclock Asic for night run possible?

[Lontor]

I've read through many mining threads and machines on this forum and one of the most common things I see alot is people over locking their Asic miner a bit more to get the best out of them.

I have not seen a lot of discussions about under clocking those Asic miners, I am looking into this because I want to try my own solo mining operation and the only solution I came up with is running full hashrate in the day and by night going the lowest I can.

I read about Avalon Q and it seems to be the only one that you can change power consumption in its settings, but I don't have money for such miner, I want something smaller and that has the capability for under clocking.

For example, let's say I can run a 300w miner from morning till evening but I only have the capacity to run 200w at night on that same miner till the next morning, you get what I am looking for?

300 watts is very little for an ASIC, I think you can choose a device for solo mining with this kind of consumption.

Electricity is usually cheaper at night, but if you want to use solar power, you need batteries for the night.

[Yamane_Keto]

Why do you do the opposite, or why would you want to reduce the frequency of these devices in the evening? If your goal is to reduce noise, then reducing the frequency of Bitcoin mining does not significantly reduce noise.

you pick a bad watt level to mine with

200 watt machines are overpriced in general as are 300 watt units.

maybe this if you are usa based

this is okay if you are in Europe

edit at Yamane_Keto maybe he has solar and battery limits.

I think he is looking to automate his units, but I don't think you can find some units that can schedule to use overclock and underclock.
If I remember correctly, Vnish or Braiins OS offers automatic profile switching based on thermal and environmental thresholds, but there's no base time. If you can buy a cheap s9 with a single hashboard you can experiment with this unit.

Instead of running the units in low-power mode at night, I believe they should be run in normal mode and then underclocked during the day using automatic profile switching to take advantage of thermal and environmental thresholds.


Newer units like NerdOCTaxe is pretty expensive nowadays, and they only have a thermal limit to automate shutdown, not based on time or a scheduler to underclock or overclock the unit.

So I think choosing cheap older units that support Vnish or Braiins OS is a good option.

I also saw the Canaan Avalon Nano 3S; it has a feature called "night mode." but it's not automated, but you can remotely turn it on via your phone.

[FP91G]

The Antminer S9 can mine 4 terahashes on a single board while consuming 450 watts of wall power or slightly less.
The main advantage of this ASIC is that it's practically free, but its power consumption, noise, and minimal chances of finding a block in solo mining make it pointless.
Cheaper than the Avalon Q, it only requires a PC with a graphics card and remote control.

[5W-KILO]

OP, how about you go for multiple small miners? I am thinking 💭

This could actually works.

There are NerdAxe with 120w that do 5TH to 6TH, three of em will net you 360watt, that's 15TH in total and you can run them from morning like you requested and when the night comes only need to off one solo miner.

You will be left with 120w + 120w = 240watt, that's 10TH for the night till the next morning?

I am guessing that you are trying to run these miners on battery and inverter?

[Jerry Bob]

If hash rate is not a concern, then of course a low-frequency operation can be used. However, if you find the noise from your ASIC miner too loud at night, you may consider installing a miner silencer. Or you can use Solo Miner as they suggested.

[ABCbits]

edit at Yamane_Keto maybe he has solar and battery limits.

If he rely on solar and battery, i think he would ask more specific question (such as how to set clock automatically with script or which app that can set clock by any variable/condition) considering unreliable weather.

I also saw the Canaan Avalon Nano 3S; it has a feature called "night mode." but it's not automated, but you can remotely turn it on via your phone.

Avalon Nano 3S use 140W adapter, so OP probably don't need to switch every night from his phone manually. But after reading related help page (https://help.canaan.io/hc/en-us/articles/43169816917529-Technical-Documentation-Explanation-of-Avalon-Mini-3-Modes), it's really weird their app/mining device doesn't have feature to automatically enable night mode with configurable time range.

Ok so I find this to be quite confusing, what does S9 Asic miner has to do with graphics card installed on a PC motherboard? Or I don't get the point you are saying? I'm lost right here.

I think OP is more concerned about power consumption over hashrate, A Antminer S9 with 14TH takes 1250w even if there is a way to downclock it we are not going to get that 14TH with 300Watt running.

The NerdQ++ Rev6.1 takes 100 for 6TH and it cost the half of the price for S9, atleast in my own country, getting two of this NerdQ++ will do the magic, 12TH for 200Watts, this is one of the reasons why I like this small miners better, for anyone struggling with power consumption they can do mining with solo miners and keep adding one by one if one day they can handle higher power consumption.

I have a friend with over 12 over these NerdAxe and he is over 100TH on Bitcoin mining, the whole miner combined are less noisy than running a single Asic miner.

I wanted to say that a computer with a graphics card, not an ASIC, is ideal for such tasks. But that's not suitable for Bitcoin mining, only altcoins.

NerdQaxe++ Rev 6.1  (6Th/s) 103W $228
Antminer S9 14TH 1250W costs $10-20 
It's difficult to compare

17 devices *230 is $3910 for 107 TH/s and 1751 watts.

The S21 200th used in economy mode will run at 150 TH/s and consume 2400 watts. It will cost $1000.

You'll also need a noise box for $100-300. $100 if you build it yourself.

I will be damned, where are they selling S9 antminer for 10/20 ? It costs way more than this in my country, even if it's used, that's freaking dirty cheap, if anyone has a way around electricity this can be worthwhile. It's just that power consumption concerns people more than anything today, electricity bill is increasing here and I use solar panels most of my life since COVID era, anything I plugged into the wall must be worth it, I will like to know your source of getting S9 antminer for dirty cheap, atleast knowing can help those who normally approach me for mining guidelines.

This is Russia. If you buy three Antminer S9 ASICs for $20 each, you'll get the fourth one for free.
Antminer S9s are hard to find in good working condition, but there's no point in doing so when you can buy a used S19 series ASIC for $50.
If you need contact information for sellers in Russia, I can provide them. But you're unlikely to be able to get them out of the country cheaply due to sanctions.

I think most modern heaters I saw on the market usually have an automatic night mode/time range feature; I don't know why this one doesn't. It's supposed to have a feature like other modern heaters nowadays.

What I think he can do is set up a cheap laptop for automation by installing an Android OS, installing the family app, connecting to the same network, and then using an auto-clicker and adjusting the time to automate the click at 5PM and again at 9AM, at least as an alternative to the feature that is missing from this unit.

He can also do it with a Raspberry Pi with Lineage OS to automate this, which is a cheaper and low-power setup.

Wow, I am just too far away from Russia to buy few of these, damn it, shipping fee alone won't make it worth doing, it's even the reason why I can't buy some miners from China and China is even closer to my country, imagine buying $300 and using $100 for shipping, this is why I always go for those who offer free shipping or extremely shipping fee, within $10 to $30 max, but thanks for sharing this, you guys are lucky, still wish there is a way around this.

All this old junk is smuggled into Russia from China. It's practically impossible to export it from Russia because of the extensive paperwork required. If you can get this junk from China, it's even cheaper there, but Chinese partners don't care much about product quality; they produce a lot of defective products.
In Russia, companies repair this junk and resell it to other miners who have very cheap or free electricity.

Underclocking is highly underrated. It actually improves the efficiency (Joules per Terahash) and extends the lifespan of the hardware significantly.

If you are on a tight budget, look into older Whatsminer or Antminer models and pair them with aftermarket control boards or custom software. However, dropping from 300W to 200W daily might stress the chips due to constant thermal cycling (going hot and cold every 12 hours). What specific models are available in your local secondhand market right now

Minor temperature fluctuations don't affect the chips unless the temperature rises above the recommended level. The ASIC's controller regulates the temperature by increasing or decreasing the fan speed.
It's dangerous when a hot ASIC suddenly shuts down, which happens constantly due to poor power supply.

You should have known better, that been cheap doesn't mean you will be getting the best products, there are probably not balanced or something isn't working properly in them, if you can't fix don't buy.

Someone bought cheap Avalon Asic miner from Alibaba supplier and he accepted a very dirty and dusty Asic miner, bro had to use several days on cleaning at first and after that's done the Asic started to behave abnormal.

I hate cheap things especially electronics, they are red flags when they are dirty cheap, like I've said already, if you don't have any experience with fixing this things don't buy them.

When buying used items, you should consider local market practices. In China, the quality of used ASICs is problematic, but they're also cheap. If you buy a used ASIC from a reputable seller in Russia, you can have it inspected on-site and have it cleaned of dust. In Russia, on the contrary, pre-purchase inspection is encouraged, because after the purchase, the seller won't accept any claims unless there's an obvious defect that wasn't disclosed in advance.

[FP91G]

Some ASICs can be under locked by bringing down the frequency and voltage through custom firmware or built in  settings, depending on the model. In fact,  under locking often improves efficiency watts per TH and their by reduces heat and noise, which can be a huge advantage for a small solo mining setup
Your reasoning of running at full power during the day and lowering consumption at night is practical if your power supply is constrainted .
The most important thing here is to find a miner and firmware combination that allows flexible power profiles rather than focusing solely on maximum hashrate. At the long run , a miner running a continues within your power budget is far good than one constantly pushed to its limits.

I think the cooling system plays a more important role here. If your ASICs are in a cold climate and you can affordably cool them with cold air to keep the chips from overheating, you can use overclocking modes.
If you're in a hot climate, you won't overclock because the cooling costs may outweigh the gains from overclocking.
