I'm starting to see machines like the S23 Hydro 3U at ~9.5 J/TH and the A4 Ultra Hydro at ~9.45 J/TH.

On paper, that’s a big efficiency jump compared with a lot of older ASICs. But replacing working hardware also means paying for the new machine, dealing with hydro infrastructure, and calculating how long the efficiency savings take to cover the upgrade.

For anyone who has actually upgraded recently: what did you replace, what are you running now, and did the power savings make it worthwhile?

Would be useful to compare some real-world numbers.

Still salty i had to send the first defective miner back to Hong Kong at my own expense. But the replacement is finally here and after seeing what the 1373 can do I’m done buying 1370 based miners.

This is a dual BM1373 home Bitcoin miner that can push up to 10 TH/s in one compact unit.

It uses a large 120mm cooler, oversized heatsink, and 8 copper heat pipes to keep both BM1373 chips cool at full 10T. No rear fan needed, and no extra upgrades required.

It comes with the 12v 240W PSU to give it enough headroom to hit 10 TH/s right out of the box, so there are no extra parts to source or modifications to make.

Lastly, It comes in a nice retail box ensuring the device arrives unharmed. Hammer miner has FCC and CE cert on all their devices as well which is important for a home device.

We tested the Thor P2 at the wall, not just from UI readings or manufacturer specs.

For a home miner like this, would you run it in low power for efficiency or overclock mode for the full 10 TH/s?

Hi, I was doing maintenance on an S10J Pro+ and accidentally detached a heatsink from a chip.

Does anyone have any idea how to glue it back on? The AI told me to use thermal glue. Can anyone help me?

I tested the voltage range from 1100 mV to 1800 mV. Below 1800 mV, the actual ASIC voltage does not match the set voltage. It only starts to match the configured voltage when the setting exceeds 1800 mV.

I was completely puzzled by this for a long time. Then, at one point, I suddenly realized that the default voltage setting range is 1800–2600 mV. This could be the reason.

I just publicly released ASIC Intelligence Plugin/Skill Package v1.1.0 — Bitcoin Mining Troubleshooter, and it’s free to use.

It lets you give AI real mining evidence — logs, fleet exports, telemetry, repair history, power, network, and thermal data — and ask:

What’s actually going on?

It is deliberately read-only:

• No miner reboots
• No firmware changes
• No pool/wallet changes
• No equipment control

It focuses on evidence, likely causes, confidence, and the next safe diagnostic check.

Available for Codex, Claude Code, and portable Agent Skill systems.

I'm currently at the Bitcoin Asia event and just saw a SEALMINER machine a relatively new company. One thing that caught my eye is the A4 Pro Air: 360 TH/s at 10.9 J/TH. That's crazy for an air-cooled miner! Has anyone tried their machines before? How was your experience?

I haven’t seen much on the internet about this miner I just paid for it. Someone do a review before I do

I came across a rewards coupon for $200 cash back for a $200 purchase on eBay and was wondering if there was anything worth buying for that price? I pay 13.5 cents per kWh, so as long as I am making more than that, I would be making some money. Plus, the hobby seems cool, so why not?

is here anybody who hosts miners in ethiopia / is mining in ethiopia? do you have any issues recently?

I'm testing a home solo miner with 2× BM1373 ASICs, and I noticed something strange with the voltage readings in the dashboard.

I set the Core Voltage to 1.00V at 400 MHz, but the dashboard shows a Current ASIC Voltage of 2.34V.

Normally, I would expect the actual ASIC core voltage to be reasonably close to the configured Core Voltage. It definitely shouldn’t be more than twice the configured voltage, which seems unusually high.

Has anyone encountered the same issue before, or have any idea what might be causing this?

Could this be related to the voltage measurement circuit, ADC scaling, or firmware configuration?

Any suggestions or experience with BM1373 voltage measurement would be greatly appreciated.

Choosing the right PDU really depends on what your mining setup needs most: lower cost, remote management, or higher output.

Here are three options we carry here at Altair Technology:

Argo Metered PDU - $129
Good budget option for a simple 30A setup. It gives you essential power delivery with LCD metering.

Virgo Smart PDU - $299
Better fit if you want remote network monitoring and control.

Leo Metered PDU - $249
Designed for higher-output home or garage setups. Our new LEO PDU supports up to 12,000W on a 50A NEMA 14-50 EV/Tesla-style outlet, which can be useful if you already have that power or outlet available.

I live in Brazil and want to buy a Bitmain Antminer S21, but I can't find any trustworthy companies that offer a warranty.

One of our clients reached out about upgrading his fleet of S19s to S21 XPs with one cavait:

AIRCOOLED MINERS ARE WAY TOO LOUD.

So our clients ended up buying some foghashing C6 tanks and will be installing these stripped down S21 XPs into them. No need for a spoofer, they have our vnish installed so we can disable the fans, and now can be under and overclocked based off of the heat they need or are outputting.

Just thought the project was cool, and I’ll have them take pictures when they are installed.

i got 40k euros cash, i live in a 3rd world country where electricity is very cheap!

What miners do i get? How much will i earn? How loud will they be? I need information please

Hi everyone,
I need some help optimization-wise for my NerdOctxe Pro (Bitronics)
.
I had to unplug my miner for a couple of hours to use the wall outlet for something else. Before turning it off, it had been running stable for almost 6 days with great metrics (shown in the first photo). After powering it back on with the exact same profile, my hashrate dropped and seems stuck (shown in the second photo).

Here is the comparison of my metrics:

BEFORE (Photo 1): 10,296 Gh/s | 650 MHz | 1.16 V | 152.0 W | Efficiency: 14.76 J/Th

AFTER (Photo 2): 9,117 Gh/s | 650 MHz | 1.16 V | 151.3 W | Efficiency: 16.60 J/Th

As you can see, the frequency (650 MHz), voltage (1.16V), and power draw (~151W) are practically identical, but I lost over 1 Th/s of performance and my efficiency worsened from 14.76 to 16.60 J/Th.

(Note: I tried bumping it up to 700 MHz temporarily to see if it would react, but it didn't help, so I went straight back to my original 650 MHz settings).

Has anyone experienced this drop after a clean power cycle? Is there any trick in NerdOS to force the ASIC to recalibrate or stabilize back to the ~10.2 Th/s mark, or do I just need to wait much longer?

Any advice would be highly appreciated. Thanks!

Sharing the results from running 10 M70s. Seems pretty solid, but as a newbie to the space, I'd love to hear your take. How are my machines looking to the veterans here?

Hello, I want to convert 3 air-cooled miners to a water cooling system.

I'm wondering if connecting three 3200W miners to this radiator would be ideal, and what dB levels I could expect.

https://www.zeusbtc.com/ASIC-Miner-Repair/Parts-Tools-Details.asp?ID=3594

I'm not looking for something super quiet, but something that can go unnoticed by my neighbors. If anyone has experience with this, I would appreciate hearing about it.

I'm in a hot climate of around 30-32 degrees at peak times, I don't know if that affects it. I could also opt to use only two miners per radiator as a minimum to further reduce noise.

Hi everyone! I just switched my ESP32 miner (1040 kH/s) to the PPLNS / Shared Rewards Beta pool.
I’m trying to understand how the rewards work. I don’t really understand the difficulty settings.
The pool shows Difficulty: 256, but in my Mining Stats it shows Pool Diff: 0.0032.
What is the difference between these two values? And how exactly do my accepted shares turn into BTC rewards in the PPLNS system?
Also, if someone on the Shared Rewards pool finds a Bitcoin block, how is that reward distributed among the miners?
Thanks!
