That 3900x is a beauty (on paper anyway).  I have a feeling it's going to be rather popular once Monero finishes their fork to RandomX.

s9 have been actively replaced s9 for a while. I would expect well run larger farms already cycled out most of their older gear.

I'm trying to get into mining, so far I have a S17 coming soon, hopefully in a week. Aside from that I'm looking at getting some other miners. I have a location I can set these miners up in a maintenance like room, so noise wouldnt be a bother. The cooling on the other hand have to figure out. Also space might be an issue I can't take up too much.

Anyways I was trying to look at miners that aren't necessarily efficient due to the electricity. I looked Ebang E10.3 24th but didn't realize it takes 2 PSUs which means 2x the cables for power. To me feels like it might take up but I'm not sure.

I'm looking to get 4-5 miners at the beginning but I am so indecisive. I keep finding one I like but then decide no because I may not know everything before I buy. Anyone mind sharing some of you wisdom please?

I just received my Pi 4 today and it didn't come with an SD card.  Can I use the SD card from my Pi 3 B+?

I tried it but it wouldn't boot.
Thanks,

you don't understand how they measure.

a single chip with test leads  can do 30J/TH

this gear is doing 50th at 2050 watts on = normal speed  that is 41J/TH

you are doing turbo numbers  to mine on turbo speeds gives you  a little more hash and burns power like mad.

so this gear does 41J/TH using the  fans and controller  on normal speed.  I suspect fans and controller are at least 100 watts

so it is  doing about 1950/50th = 39J/TH on normal speed

In what seems like a million years ago bit fury shows its chip in a single chip setup  it did 60J/TH  which when built into a  big machine did about 100J/TH

Turbo should never be used at the moment with current coin prices.

Normal speed should be used at the moment with current coin prices.

But I am sure some can create an example that shows turbo is smart to do at the moment.

UPDATE: I remembered I had a dual metered PDU that reports amps (in whole numbers) that I don't use that readout anymore.  So I tried one of the S17s on that so I could measure each cord separately.  It measured exactly 5 amps each on Turbo mode.  Exactly being that it only reports round numbers.  At my voltage that is around 1150 watts per cord.  But I'm sure it is 5.x not just 5 amps.  But either way, it seems to balance the load very close between the two cords.


I'd like to see your calculation/thinking.  

By my profit model turbo mode makes sense currently.  But I am working with 5.4 cent electricity so that obviously will make a difference.  Simple Cryptocompare shows $8.50/day for Turbo, $7.84/day for Normal, $6.24/day for Low Power mode.  So Turbo currently makes the most profit.  I have wondered if the extra wear and tear is worth it and for that extra 8% profit and maybe not.  

As energy price goes up then it would flip to where normal would win out and then low power mode.

He set his range to 80 dB and I believe gear is at normal speed.

Try one of your s17s on normal speed and range at 80 dB.

As I see specs turbo looks to be really hard on  unit with not much gain in hash.

But this is not my gear as I was not able to order on in first batch. Since then I have decided to not purchase any new gear from bitmain.  I will buy used s17 from forum miners, but not from bitmain direct.

Thanks for information.
My question is that do we need such a high speed SSD?
My current build is using https://www.amazon.com/gp/product/B01M9K0N8I/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1
The speed for this is see is Read/Write up to 560/520 MB/s *Performance vary by ssd model
However the one you suggested is 3 times for the $100 corsair one.

Everything that is not a bitcoin is a shitcoin?
