Hey Tupsu, any particular reason you did the 4 blade setup?  I have the water cooling kit, but haven't installed it yet, and was wondering whether I would do that or not, wasn't sure if it was worth the hassle on the connectors.

Also, your HW error rate looks really high relative to what I see on my S5's, is this a byproduct of the quad blade  - perhaps the extended cable lengths?  I2C/SPI can be pretty sensitive to cable length...


The reason was that I sent one Controller to bitmaintech warranty.

With Original S5 fans I had a better result.

may all be a moot point don't know what will be asking price and shipping price of the big one.

Yeah, it could become a rather pricey experiment to conduct (big $$$$).

From what I read, ~$3300 each, and they require more power than most houshold rooms (USA) can safely relay.  A garage or shop with a 220V circuit may be able to do the job.       --scryptr

right now it is 2750  usd on bitmaintech's chinese website


the usa seller wants 3299 plus 75 to ship  so It would be 3374 from him.  I get some very small discounts if I use paypal so it drops to 3314.  Which is too much.

But bitmaintech at 2750 + ? to ship could be  under 3000.  Still too much but closer to what I want to pay.

I ran some ROI math at 2.7K I personally cant justify it as much as I want to.   It is better then resellers.  Quite honestly I'm getting tired of resellers adds one extra layer of paying more.  I would rather get direct.   SFards seems to have made resellers happy which is not a good way to go for hobby miners.

But I agree would love to own one just need to get it at a lower cost.

 About the same error rate per hour, actually. STILL way high on the error rate. I'm starting to think MarkAz has a point on the long cable lengths.

 You're assuming you have to run it from one circuit.
 Granted, most "rooms" in the US only have 1 or 2 circuits, and if 2 the second one would commonly be lighting-specific, but a lot of rooms ESPECIALLY kitchens, most garages that have power at all, and pretty much all homes have multiple circuits available and plenty of space in the breaker box to add more circuits (worst case have to replace a few single-circuit breakers with dual-circuit type).


 On the other hand, the S5+ wasn't intended for "home" miners - the regular S5 is still Bitmain's better option there for the time being 'till they run out of used ones from Hashnest/farm usage and finally start selling the S7.

 I have to wonder how many "weekly" Batch 7's they're gonna need before they run out (or essencially out).

For USA customers ,  ITOP Shop  will Ship locally from NY , thanks.


Will that price include shipping?

If Bitmain is selling direct for $2750, I'd rather go there, ship direct and take my chances with customs.  Your price is too high to yet add shipping on top, if their price does end up as stated.

yes , that price can have  shipping cost be included , if use USPS for 12KG goods , will not cost much .

NICEHASH ANTMINER S5 BIOS--

NiceHash has posted an Antminer S5 BIOS in the proper format for flashing from the Antminer web interface. Here is the link:

"https://www.nicehash.com/download/AntMiner-S5-SD-firmware_cgminer_4.9.0_nicehash_and_performance_graph.tar.gz"

It has CGminer version 4.9, and this CGminer version is patched for "extranonce subscribe".  This is a useful patch for mining on NiceHash, but I haven't tried it.  I don't know which Antminer firmware version is in this particular BIOS image.

Has anyone tried this BIOS image?         --scryptr

NOTE:  I don't post often in this thread, but I am concerned about the safety of this alternate BIOS.  Someone please make an intelligent comment.        --scryptr

P.S. Running high wattage in the kitchen after disconnecting a built-in stove or range-top is LAUGHABLY absurd.       --scryptr

Hi guys,

I have 2 questions but i not find the response:

1 - Which are the best settings for Antminer S5 of expirytime-scantime-queue for solo stratum pool (ex. tbdice.org)?
2 - If difficulty is set to 1024 cgminer (v4.8.0) not show share (Accepted 00000080 Diff 0/1024 ) and best share it remains 0 ...this is not a problem for normal pool but for solo pool it's ok? (if i change diff work fine= Accepted 3e047efc Diff 1.06K/341 )

Thank you

ps: i use S5 with latest firmware

I have no idea where to find answers...can you help me?

just saw the new twitter news from BITMAIN
We just released a new @Hashnest_com product: 1 TH/s for 0.666 BTC. Check it out: https://www.hashnest.com/l/YeZ8DTrTeHc  #bitcoinmining #bitcoin
Will this affect AntMiner S5+ for BITMAIN  to be delayed to opening sales to oversea market ?
Since some potential antminer S5+ customers to purchase the cloud mining contract instead ?

Hashnest is pleased to announce the latest version of our PACMiC cloud mining subscription! This newest offering, Version 3, offers a cheaper per-terahash price point and higher reward payouts than before.





Hashnest continues to be the world's leading cloud mining platform, and is one of the few cloud mining services to manufacture its own hardware. This significant advantage allows Hashnest to maintain a competitive edge over sites offering similar services. As a trusted supplier of physical mining hardware and ASIC chips, Bitmain & Hashnest are able to supply the large amounts of real hardware required to run such mining operations.

The PACMiC is a cloud mining offering for those who would like lower risk but more predictable and reliable payouts from their cloud mining contracts. PACMiC contracts do not charge a maintenance fee, and do not expire based on the cost of bitcoin. In fact, owning PACMiC is a way to hedge against bitcoin price drops, as PACMiCs give their owners mining revenue payouts even when the price is low.

This latest version of PACMiC offers users a bonus payment of 0.8 satoshis per second, per bitcoin outstanding until the contract ends.




About PACMiC

Each PACMiC V3 represents one terahash of mining power, and is sold for 0.666 BTC. The contract begins immediately upon completion of payment. Once the contract is in effect, users will immediately begin receiving the mining revenues from 1TH/s of mining power; payouts are according to AntPool’s PPLNS method. Electricity and maintenance fees will be borne
  
Each time a PPLNS payout is made, it will go towards paying back the 0.666 BTC initial purchase price. Additionally, a bonus payout of 0.8 satoshis per BTC per second is also made to the user. The contract expires when the user has mined the original 0.666 BTC purchase price. In the event that the mining machine becomes unprofitable (calculated using the electricity cost of USD$ 0.098), the contract will be suspended until such time that payouts are able to made again. Unlike regular cloud mining contracts, a PACMiC does not terminate when the bitcoin price falls too low, it just becomes inactive.

A 0.666 BTC PACMiC V3 contract represents 1 terahash of mining power, making the PACMiC V3 the cheapest cloud mining contract yet. Other cloud mining services generally price one terahash of mining power between 1.5 and 2 BTC.

With PACMiC, users no longer need to worry about high electricity fees or soaring difficulty. Mining with PACMiC is less stressful.

PACMiC Details

What is a Payout Accelerated Cloud Mining Contract (PACMiC)?
The PACMiC is a value-added cloud mining service product from Hashnest. The PACMiC is an electronic contract structured in a new way. BITMAIN will pay all the maintenance costs of the mining rigs, and all mining revenue will be used to pay back the PACMiC owners. While the principal is not yet paid back in full, it also makes bonus payments to PACMiC owners. When the principal is paid back, the mining rigs continue belong to BITMAIN. Both principal and bonus payments will be made to the contract holder based on the mining revenues of AntPool. Because PACMiC owners do not have to pay for maintenance or electricity on the machines, the payout is accelerated.

Purchasing a PACMiC
Each unit of PACMiC V3 will cost 0.666 BTC. Each PACMiC represents one terahash of hashing power. The contract will become active immediately upon receipt of full payment.

Computing principal and profit of an PACMiC
As soon as the PACMiC is activated, payouts will be made through Hashnest in accordance with the mining revenues generated by AntPool’s PPLNS payout method. Reward payments will be made beginning with the first block found by AntPool after the contract’s activation. From the first block until the contract’s expiry, reward payment will be accumulated every second, based on the total amount of the purchase price which has not yet been earned back through mining revenues.

Example: Alice’s PACMiC has already mined 0.166 BTC, so the contract will expire after mining 0.5 BTC more. Alice earns a reward payment of 0.4 satoshis per second based on her outstanding balance of 0.5 BTC. After mining 0.1 BTC more, her rewards rate is now 0.32 satoshis per second.

Profit Calculation Method
Outstanding [not yet mined] coins (BTC) * 0.8 (satoshis per BTC per second) * time to find a block (seconds). For every block found, the remaining mining revenues after the bonus is paid will count towards the outstanding bitcoin.
 
Please note: information on blocks found will only be transfered to Hashnest.com from AntPool after receiving six network confirmations. Because of this, profit and principal payments will be on a slight delay from the bitcoin network.

Contract Suspension
If after 120 days, a PACMiC has still not mined back its initial purchase price for the owner, and is not mining enough bitcoin to pay for its own electricity cost (fixed at 0.098 USD per kWh, calculated using AntMiner S5 specs, hashing at 100% uptime on PPLNS method), whether due to difficulty increase or BTC price decrease, the PACMiC will continue paying out for ten days as though it were running, even if the machine is turned off. If these conditions persist for ten continuous days, the contract will be considered temporarily suspended. During the suspension period, mining revenues and profit payments will be temporarily halted. If after the suspension period, difficulty has dropped or bitcoin price has risen, making mining possible again, the contract will be reinstated and continue from where it left off.

Contract Expiry
The contract expires when the user has mined enough BTC to cover their initial purchase price.
BITMAIN reserves the right to make mining payouts in advance, before the purchase cost has been paid back in full.


FAQ

Q: Can the PACMiC be sold or transferred to other users?
A: No, PACMiCs may not be traded or transfered to other users.

Q: Do PACMiCs deduct electricity and maintenance fees?
A: PACMiCs do not deduct electricity or maintenance fees, these expenses are covered by Bitmain.

Q: Can I redeem my PACMiC before contract expiry?
A: No. The contract will be closed automatically at the time that the initial contract price has been repaid in full. Contracts may not be terminated prior to this, although BITMAIN may exercise the option to make advance payouts of mining rewards.

Q: Does PACMIC offer hardware delivery after the contract ends?
No, PACMiC is different from Hashnest's other cloud mining services in this regard. After the contract ends, the machines remain the property of BITMAIN.

Q: If AntPool experiences bad luck, will this affect bonus payments?
A: Bonus payouts are calculated using the amount of initial contract price that has not yet been paid back, and are unrelated to the pool luck of AntPool. Changes in pool luck will only affect the speed at which mining revenues are paid. Bonus payouts are earned at a steady 0.8 satoshis per bitcoin outstanding per second.

Q: How can the user make a profit?
A: Bonus payouts are calculated using the formula: unpaid principal (BTC) * 0.8 (satoshis per outstanding BTC per second) * time to find a block (seconds). Mining revenue will first be used to make bonus payments, the remainder of mining revenue will then count towards paying back the initial purchase price.

Q:When does the user start to get the bonus payout? Where does the bonus go?
A: Bonus payout begins accumulating as soon as the first block after contract activation is found. The bonus is paid directly to user’s wallet on Hashnest.com.

Q: What does the Auto-Rebuy feature do?
After enabling the Auto-Rebuy feature, your bonus payout will be used to automatically and incrementally purchase more mining power through the PACMiC.
When the feature is disabled, mining revenue and bonus payouts will continue accumulating inside your account as usual.

Q: If I have auto-rebuy enabled, when do those GH/s expire?
Same terms as before -- PACMiC hashing power expires only when the purchase price has been paid back to the owner. If the BTC price drops too low and the contract does not generate revenue, the contract becomes suspended (but not ended) until such time that it may generate revenue again.

Q:When does the contract end?
A:When the initial purchase price has been paid back through mining revenues.

Q:Is the PACMiC risk-free?
A: Like all forms of bitcoin mining, there is a certain level of risk involved. If the Bitcoin network difficulty skyrockets, or if the price of bitcoin drops too much to cover the electricity fee, the Antminer S5 units backing the PACMiC may not be profitable to run and be forced to go offline, in which case contracts would be suspended (possibly indefinitely) and the user may not recover the initial cost of the miner. The AntMiner S5 is currently one of the most power efficient bitcoin miners available on the market, and would be among the last to be forced to power down under unfavorable market circumstances. All users should do their own research and understand the risks involved with bitcoin mining, and also to understand that there is no such thing as a risk-free product.

OK. S5s are out. Bitmain finished replacing S5s with something new at their farms and offers the Pacmic3. We probably will see S7 sales start soon.  Cool

Also, your HW error rate looks really high relative to what I see on my S5's, is this a byproduct of the quad blade  - perhaps the extended cable lengths?  I2C/SPI can be pretty sensitive to cable length...



With Original S5 fans I had a better result.


 About the same error rate per hour, actually. STILL way high on the error rate. I'm starting to think MarkAz has a point on the long cable lengths.

I'm not ready to believe it.
My first  water cooled S5 which is in the housing of C1 .  C1 pump and the radiator with 3x better fans.
One long (15cm) and one standard cable. 16 pin version.
10 day error rate 38
