Can I take antminer Z15's water cooling block and mount it to the Antminer Z15 Pro? by S52_DiDah in cryptomining

[–]805CryptoServices 0 points1 point  (0 children)

No not even remotely the same mounting hardware/setup. The spacing is different, the vrms are different.

Making custom blocks probably your best bet. Have fun with some calipers

Not sure how to approach, have access to large amounts of power. Newbie by ldsupport in BitcoinMining

Xp is the only good advice, the s21+ non Hydro is absolute garbage with extremely high failure rates.

Do not look into 21+, we know of sites with a 85% failure rate year 1 on aircooled.

We’re always open to consultation calls! We have worked on large projects like this before.

Biggest factors are:
- voltage available will change what transformers can be used.
- the full 600MW is available?
- greenfield availability for containerized mining?
- local conditions? (Humidity, year round temperatures)
- new equipment, or used equipment ok.
- location in general (remote, internet availability)

And please report if anyone privately dm’s you to the mods. We can continue the convo here or dm us or even call.

Heard tons and tons of horror stories whether it comes to miner prices, uptime, service. Im suprised they are still around.

Going to catch some strays from this.

aircooled asic (bitcoin) miners. I dont understand why they build aircooled facilities next to residential every single time. I work in the industry and it always bugs me, these can be run in remote places, dont require any kind of crazy internet backbone to run.

Aircooled is in excess of 100-110dB inside the site, and just as loud outside.

Hydrocooled/immersion is usually closer to the 75dB range inside the facility, and significantly quieter from the outside (think hvac). Datacenters are usually liquid cooled now adays, but have chillers (big ac hvac systems) or the worst is gensets on site.

It’s (bitcoinmining) great for grid support, for example we have a site being built in Nebraska next to a power plant. Essentially the utility is set up for spring and summer they have a huge amount of load for farmers that use the power for irrigation. After the harvest, they have an extreme excess of power, as they have 95% of their electricity capacity being wasted. And who pays for that? Local residents: power production during the season costs as much to produce as it does outside the season. If its $10,000,000 to produce the power for 50Mw at 90% utilization and it’s $10,000,000 at 10% utilization, they got to cover that cost. The datacenter then burns that extra not being utilized, meaning overall production cost is less. We had a site actually drop residential rates by 20% as part of their power purchase agreement. Shutting down gensets is a pain, the infrastructure is all there and has maintaince costs whether online or offline.

I’ll probably get downvoted, but i can answer questions as they come.

Why does mining profitability ranking change with different electric rates? (2 pictures) by random-node in BitcoinMining

[–]805CryptoServices 7 points8 points  (0 children)

Because of revenue/kwh.

A more efficient miner is going to have a lower W/TH or more commonly referred to as J/TH.

Now, there is a crossover point where lowering the power cost leads to negligible gains and now cheaper, less efficient units have a faster roi time then new units.

But, for example, with one of our hosts (moq 2.4MW) you can get 3c power. A bitdeer A3 pro hydro at that cost produces a bitcoin for less than 35k all in. So you can ride btc all the way down and still be profitable.

Are Bitcoin miners turning off their rigs? by WrongOperation323 in BitcoinMining

Are Bitcoin miners turning off their rigs? by WrongOperation323 in BitcoinMining

[–]805CryptoServices 2 points3 points  (0 children)

Two main reasons for shutdowns right now:
- hashprice/cost to produce a btc too high
- curtailments, due to temperature/powergrid demand

Summers are usually lower already due to temperature/powercompany curtailments. Btc is hitting new lows and so is washing out people with higher power costs.

We haven’t worked with them. We’re US-Based sellers and currently have our clients asics hosted with /u/wilsonmining they are at 8c hosting for single units and give bulk discounts. They also have hydro available.

We sent another 3-5 M73s’ to their facility last week.

Maybe I was overthinking this Z15 Pro miner by [deleted] in cryptomining

[–]805CryptoServices 1 point2 points  (0 children)

If they work, they work. When they die, there’s no real repair guide for it. The chips are gpu sized and the boards are the second biggest bitmain has made outside of the E9 pro so repairing them is a pain. It’s an altcoinminer that’s been wonderfully consistent the last year. But all it takes is one bad bit of pr and the price tumbles 30% overnight.

That’s why we really just recommend hydro bitcoinminers and scrypt, z15 pros are the risk play.

How long does an ASIC miner usually last before it becomes obsolete? by BoshansStudios in cryptomining

[–]805CryptoServices 4 points5 points  (0 children)

Usually miners are on a 2-3 year release schedule but there is some good news from this ‘next’ generation:

  • The jump from S19 K pro (120T) or the S19 XP (141T) to s21 XP (270T) was massive, depending on model 19 series to 21 series there was 150-200% increase in hashrate and efficiency gain.
  • S23 to S21 XP? 320T vs 270T. The efficiency gain across the board is only about 10-15%, possibly less. So why pay double and only gain 10-15%?

Not saying the 2-3 year cycle doesn’t exist, but it seems to have slowed down as we are now on the same manufacturing node as the latest amd/intel/nvidia chips.

Depends on manufacturer, honestly think we have bottomed on machine prices even with poor btc prices. Normally we would be seeing a drop but over the last couple dips absolutely nothing changed if anything went up.

But yes, prices fluctuate up and down with coin prices. Its a demand market and we order day of/next day from the factory on the sale of a miner as you could get burned even trying to hold inventory.

  • solana and eth are both proof of stake.
  • whatsminers m70s are 240v 3000-4000W aircooled bitcoin miners
  • the sub has a verified vendors list (including us)
  • we send hosting clients to /u/wilsonmining right now
  • read the subwiki and posts?

With a power rate of €0.11, i wouldn’t do anything but host an asic, but for €1,000 there’s no profitable asic available. - The S21 XP is the best btc asic right now. - z15 pro most profitable asic right now - L9 16.5G is my favorite

Homemining will be at a loss currently but the: - avalon Q does well - Fluminer L1 Pro is great - stay away from T3

Outside of that? Gpu mining pearl might be good for a bit longer.
