• This post focuses on commercially available USB and Desktop style Bitcoin mining hardware.
• USB and smaller desktop sized miners are not novel. They were commercially available as early as 2011.
• A summary of speed & performance from 2011 to present.
• Exploration on what has driven the revival of owning and operating a USB or desktop device.

Someone recently shared pictures of heatsinks on the newly released Antminer S19j Pro+.
There's a separate heatsink for each chip here, instead of the large integrated bolt-on heatsink on other S19 models.
Does this look like we're back to S9 style, or did Bitmain go back to the notoriously unreliable S17 style heatsinks again?

Recovering exhaust heat from ASICs can add additional revenue streams for Bitcoin miners.
As mining becomes more competitive, this becomes increasingly important.

Carnot Efficiency is the theoretical maximum % of the energy that can be recovered from a heat source.
Current ASICs exhaust heat at a much lower temperature when compared to Steam Power or Internal Combustion engines.
This limits the Carnot efficiency & usefulness of exhaust heat.


Is anyone building ASIC miners with a hotter exhaust temp & better heat recovery potential?

Stumbled upon this website upon googling 'compac f'. Looks like a pretty brazen scam.
Don't lose your bitcoin to them.

Bitmain used Xilinx, BeagleBone and AMLOGIC control boards on S19 series of miners. Three different makes created a lot of hassles for anyone trying to overclock, run aftermarket firmware etc.
It appears that they have now introduced a 4th model to the mix and this one looks like a Bitmain in-house design. It's the CV1835 board. One of our recent S19 XP came with this board.


more pictures here.

Needless to say that more board designs will create more hassles for miners, firmware developers, and resellers. Buyers often want to purchase machines with specific CBs and there's no way to tell until you open the factory-sealed box.

I'm looking to understand Bitmain's rationale behind using so many different CB models from others here. It can't be a shortage of Xilinx boards, because Bitmain has had those on sale on their website for a long time and people can purchase as many as they like. Is this just an attempt to thwart the development of aftermarket firmware?

Season's Greetings!
Starting a new 2023 difficulty thread, since the next adjustment will be in the first week of 2023.
Looks like this week's winterstorm, has triggered curtailment with public miners.

About 30% of the new whatsminers we've purchased over the last few months are DOA on one hashboard (typically error 540, 541 and 542).
We started purchasing whatsminer in 2020 after the Antminer S17 series reliability issues, but it appears that whatsminers are having the same issues now.
Anyone else notice a drop in quality from MicroBT?

We carry repair and replacement parts for most Antminer and Whatsminer models.
We manage our own megawatt scale mining farm and understand how critical it is to minimize downtime for bitcoin miners.
We carry all our inventory in the US and orders typically ship the same day.

[Anyone know if there's an easier way to 'disable' one problem hashboard on whatsminers without having to physically remove the hashboard.]

So we have multiple m30s units that have a problem with one hashboard. Something like 'error 542- Slot 2 loss balance'.
Miners with this type of issue, seems to get into a never ending, restart loop and don't hash on any hashboard, even though the problem is with just one board.
We realized that we can physically remove the problem hashboard from the miner, and then the unit starts hashing on the remaining 2 hashboards.
However physically removing hashboards takes time, and messes up the air flow dynamics inside the unit.

Anyone know if there's an easier way to 'disable' one problem hashboard on whatsminers without having to physically remove the hashboard.

We have lots of C20 to 2x C13 cables in stock in Missouri.
These are great for connecting S19 and S17 series Bitmain Antminers to PDU.
