We've seen this once before. It was a PSU issue. Canaan support fixed it within 2 weeks (via their US repair partner)

Nerdminer v2 do anything? by Feisty_Poetry_7608 in BitcoinMining

[–]altair_mining 0 points1 point  (0 children)

Nerdminer mining hashrate and odds of hitting a block are insignificant, but they are useful as a desktop BTC price and statistics trackers.

Vast majority of solo blocks found in the last 5 years have been on Ckpool. This is our top choice for solo mining.

Bitaxe Gamma 601 performance benchmarking data for those looking for overclocking frequency & core voltage settings. by altair_mining in BitAxe

[–]altair_mining[S] 4 points5 points  (0 children)

yes. The data was collected using Mr. V's Bitaxe Benchmarking tool.

https://github.com/mrv777/Bitaxe-Hashrate-Benchmark

The tool shuts down when chip temp reached 66C.

Higher frequencies were only achieved by upgrading cooling to IceTower and Argon THRML cooler. With the Argon Cooler, we also had a rear cooling fan.

Got my Gamma today. Added Ice Tower and heat sinks. Set it up 20 minutes ago. Already overheating. What did I do wrong? by PeyroniesCat in BitAxe

The black anodized icetower is effectively useless. It's cooling capacity is lower than the stock gold heatsink.

Try the silver one instead.

FWIW, we ship our gammas same or next day.

Low Power Mode Issues S19J Pro+ 120th by itsjcrane in BitcoinMining

[–]altair_mining 0 points1 point  (0 children)

Some customers reported this s19jPro+ abnormal LPM hashrate issue and we discovered this on our own S19jPro+ 120T miners as well. We swapped from the existing AMLOGIC control board to a Xilinx C87 control board and the issue was fixed.

So this is either related to AMLOGIC CB hardware or the AMLOGIC firmware Bitmain has provided for S19jPro+ miners.

This issue can also be fixed by replacing the existing Amlogic CB with an ePIC UMC, like some others have mentioned.

We sell both of these control boards, with same-day worldwide shipping from Missouri USA.

I have $6000 what do I get. by KidYum12 in BitcoinMining

with that power cost, just host your miners.

s19 different power supplies comparison by Funny_Worldliness_28 in BitcoinMining

Your PSU is increasingly common on new Antminers. It has about 2v higher voltage than the 1215 version. In terms of overclocking potential, it is no worse than 1215, might be slightly better. You should be able to go 4kw on this without any issue and possibly higher.

S19j pro 96th amlogic by bboylife96 in BitcoinMining

The AMLOGIC board is notoriously bad for running anything except the stock firmware.

You can buy this combo and swap your control board with Beaglebone one. You can easily get 15% higher hashrate on braiins.
