Question for the experts, in your experience, which is the optimum configuration for the CompacF 3D printed fan, pull or push configuration?

Thank you for your insight.

Sorry @n0nce for the misunderstanding, I already have these 2 Hubs and the Gekkos running. I was just trying to see which single board computer will give me the optimum setup. I already have them all except the RPi 5.
As you mentioned, the R909s would be better if I did not have those 2 Hubs and Gekkos.

Congratulations to @kano, the block finder and all the PPLNS miners.

If I am not mistaken, the solo pool is relatively new. It started at the end of 2021. I don't think many people are aware of this fact and hence the low hashrate. The PPLNS pool was there since the begining.
The solo pool did mine a first block (block 706,643) when kano was testing it for reliability and he give it all away to the PPLNS pool miners! Shocked

Now let's see a solo pool block! Smiley

For GekkoScience CompacFs with their GekkoScience BaseHub, which is better to use, a RPi 3B+ 1GB, RPi 4B 8GB, or a RPi 5 8GB? Also what do you think of Orange Pi 5 Plus with 16 GB of RAM? Or it does not make any difference to what to what I use?
Use the cheapest, lowest-power device for best efficiency. I've ran all my GekkoScience stuff on a Raspberry Pi 2B+, no issues whatsoever and pretty low power consumption.

How many sticks are you looking to run?

Thanks.
2 GekkoScience BaseHubs with 6 GekkoScience CompacFs.

Great, thanks for your insight.

It probably doesn't make any difference. I think all of the above would have enough horsepower to maintain the USB timings. It doesn't take much, until you start loading up a bunch of sticks, and then the problem is more to do with OS scheduler timings interleaving than with CPU/RAM.

Thanks @sidehack.

Should you daisy chain 2 GekkoScience BaseHubs together and plug it in the RPi or should you connect each GekkoScience BaseHub to a separate RPi? Or should you just plug 2 GekkoScience BaseHubs to 2 different USBs on the same RPi?

Also which OS is better on the RPi for the GekkoScience BaseHub with better OS scheduler timings, Raspian or Ubuntu?

Happy new year to all.

You can get it back (for a price) and hope a 3rd party shop can fix it (which they can if they are good).

A large company like Bitmain surely has all the means to fix stuff they make. They are just not bothered like you said.
11  Bitcoin / Mining / Re: Scrapped S19XP on: September 25, 2023, 11:27:05 AM
Did you buy it new from Bitmain or new from somebody else?

I bought it brand new from Bitmain directly.
12  Bitcoin / Mining / Re: Scrapped S19XP on: September 20, 2023, 10:48:37 AM
I used the UAE-DXB service center.
13  Bitcoin / Mining / Re: Scrapped S19XP on: September 17, 2023, 07:28:55 PM
Thanks for your kind help guys. I have already paid Bitmain to send it back to me. Now I will follow your advice and send it to someone who can fix it.
I am just disappointed with Bitmain.
14  Bitcoin / Mining / Re: Scrapped S19XP on: September 17, 2023, 06:25:39 PM
It was a virgin S19XP under warranty. I did not tamper with it because of the warranty.
15  Bitcoin / Mining / Scrapped S19XP on: September 17, 2023, 05:32:29 PM
Hi,

My Antminer S19XP stopped working and was still under Bitmain's warranty. I sent it for repairs and they told me that the miner is scrapped so no warranty applies to it.
They said: "If you would like us to return all the scrapped products to you, please CONTACT US within 5 days otherwise they will be discarded. You need to pay for the additional cost incurred including the return shipping cost, local customs duties and taxes".
I am just appalled that such a big company has such a poor customer service and warranty. Just because a hashboard is not repairable they want to scrap the whole miner?! They could easily replace the faulty hashboard. Why such a frail warranty? I even offered to pay for a replacement hashboard.
They did not give me any feedback on why it was scrapped. After emailing them several times, they sent me this low resolution blurry picture. And again after more emails they told me that the hashboard no 2 is scrapped. Can someone please make out what is wrong with the hashboard in the picture?

@mikeywith

Thank you for your reply.
All I wanted was to clear some confusion people had about the Nerdminer and the Bitaxe. But ended up being confused with someone else Grin

Thank you for your further mathematical analysis on the Nerdminer.
Now having said that, somehow I have been accused of things I did not say...

but you can't dismiss the whole project and accuse it of being a virus or accuse the devs behind of being cons who "sell" products that don't work, it's open source people do whatever the hell they want with it, if I manage to flash Cgminer to my 10$ calculator and use that to mine BTC -- it doesn't make Cgminer stupid.

Please show me where I accused the project as being a virus or the devs being cons? All I said was that

No one will ever find a block with a hashrate of 55.99 KH/s.
  I agree with the idea that an ESP32 microcontroller can control a miner without requiring a computer, RPi or an FPGA is very innovative and great. On top of it having WIFI so you do not require ethernet is great.  I personally have a LILYGO T-Display-S3 ESP32-S3 on my desk with NerdminerV2 1.6.2 firmware on it. I use it to see the time and the price of BTC. Also as a 'bonus' it mines BTC at 55.66 KH/s. Will it ever find a block? No. Do I ever expect it to find a block? No.
Now the idea of the ESP32 microcontroller has gone into Bitaxe which changes everything. But they are different projects. If they merge in the future then that would be even better. Incorporating the LILYGO T-Display-S3 in Bitaxe and loosing the ESP32-S3-WROOM would be nice.

It's naive to assume that everyone else is stupid, It's fine if you want to give advice here and there, but it's rude to assume that everyone else is ignorant.

Again, please show me where I assumed everyone is stupid and ignorant? I also have 2 Bitaxes on my desk. I support the project and the devs for their great job in making it opensource and being so supportive. I sincerely wish them all the best.

@mikeywith, I really do appreciate all the years you have spent helping and supporting people on this forum in two different languages! I sincerely wish you all the best.
18  Bitcoin / Mining software (miners) / Re: Bitaxe ESP32 miner firmware released! on: September 12, 2023, 12:13:27 PM
There is definitely some confusion going around here. I think it could be because of this article... https://cointelegraph.com/news/cheap-micro-bitcoin-miners-fight-btc-mining-concentration-inventors-argue

There is the Nerdminer, Bitaxe, and the Opensource website. All these projects are opensource. Let’s try to clear things out.

What @kano is referring to, is the nerdminer which is BitMaker's project and hashes around 55.99 KH/s.  The nerdminer uses the ESP32 microcontroller chip which has WIFI and Bluetooth and has the ability to control the miner instead of a computer or a RPi and connect directly to the internet through WIFI. However, in the nerdminer instead of using the ESP32 to control the miner, it actually mines with the chip similar to a cpu.  I totally agree with Kano and his detailed mathematical analysis of the nerdminer. No one will ever find a block with a hashrate of 55.99 KH/s. Kano does not support CPU and GPU mining for obvious mathematical and financial reasons.

Now Bitaxe on the other hand is a totally different project. Bitaxe is Skot and team's project and it uses the same ESP32 chip like the nerdminer but it controls the ASIC chip instead of mining with it like the nerdminer. The bitaxe is same as Gekkoscience's Compac F but opensource and uses a single BM1397 ASIC chip and hashes around 300-350 GH/s.

To make things more confusing, there is the new bitaxeUltra which uses the S19XP ASIC chip which is the BM1366 and hashes about 527.2 GH/s.

To make things further confusing, there is an upcoming bitaxeHexUltra which is in the works and is similar to the Gekkoscience R909 but opensource and have 6 BM1366 ASIC chips instead R909's 6 BM1397 ASIC chips. So, we are talking about ~ 3.1632 TH/s per miner.

As for the website, Public Pool, it is an open source btc pool for mining and it states “Pleb mining (under 50TH/s miners) mine with NO FEES
Miners with > 50TH/s will incur a 1.5% fee, a portion of which will go back into open source Bitcoin mining”. The pool accepts all miners to mine on it, like the Nerdminer, bitaxe, bitaxeUltra, etc.

Take home message is that the Nerdminer and Bitaxe, are completely different opensource projects. They should not be clubbed together and cause confusion.
19  Bitcoin / Hardware / Re: ASIC chip noobie maintenance question on: September 02, 2023, 03:27:34 PM
You can only interchange between the BM1397 ASIC variants because the CompacF and the R909 were designed with the BM1397 ASIC chips. The variants are BM1397AG, BM1397AF, BM1397AH, BM1397AI, BM1397AD. However BM1397AG and BM1397AI are commonly used and available. Some say that the BM1397AI is better than the rest and hence more expensive.
No need to change any drivers because they are all BM1397 ASICs.
You cannot use BM1366 ASIC (Antminer S19 XP) in your CompacF or the R909. You need to redesign a new circuit board and components for it to run. BitaxeUltra board by Open Source Miners United uses the BM1366 ASIC. It's an open source and you can make it yourself.
