I have had 39 SP30s running 2.5.12 so far for about 12 hours 16 minutes with no apparent issues. If I see no problems with 2.5.12 by next morning, I will probably move the rest of our machines over to it. Otherwise, I will probably move everything back to 2.4.23.

I've had a plethora of "disabled (bist cant start, stuck X)" errors on the remaining 100 or so SP30s we have running 2.5.6 in the mean time. It seems every few hours, I have to restart cgminer on 5% or 10% of our machines to get them back to full hashrate. Very annoying, but so far the issue has always been resolved by restarting minergate.

I've also had several reports of machines on 2.5.6 showing half hashrate at the pool even though I see full hashrate. These issues have always been restarted by a minergate restart.

I saw some much more serious problems on 2.5.7 during the 36 hours we had machines using that version. We saw about 10 machines get "Loop serial failed x" error messages (where x is a loop number, between 0 and 9 inclusive) and fail to start until one or sometimes two ASICs on that loop were disabled. After a few hours, many of these ASICs could be enabled again, but about 25% of the ones that failed are still non-operational. Currently, I think there are 9 ASICs which we lost on 2.5.7 which have not recovered.

It's possible that the potential ASIC-damaging bug in 2.5.7 might still be present in 2.5.12. I haven't seen any indications of it yet, but I also haven't had enough machines running on it for long enough to be certain. On 2.5.7, I saw the loop serial failed ASIC damage thing with about 5% of our machines per day. At that rate, there's only about a 63% chance that I would have seen it if it were present at the same rate in 2.5.12 with 39 machines running half a day.
It is now looking like the issues we've been seeing in our datacenter with the potential ASIC-damaging bug was not related to version 2.5.7 per se, but is instead temperature-related, and we only noticed it now because the temperatures in our DC only recently started getting really close to 0°C. Version 2.5.13 does not appear to fix these issues. Zvi is looking into it further.

The other two bugs were definitely firmware related, so you should still avoid 2.5.6 and 2.5.7.

Findings are still tentative and provisional, and investigation is ongoing.

new SP20 price! $795
with discount code and shipping of 2 units (3.4TH): 4.5 BTC

7* bitmain S3+ units (3.4 TH) with coupons and shipping this week = 4.7 BTC
4* Bitmain C1 (4TH) with watercooling and shipping this week = 5.3 BTC   (4.64 for 3.5TH)

wrong math

1x SP20 price! $795+shipping   1700GH/s
2x C1 price   $800+shipping    2000GH/s

Which one is more GH/s ?


Which one requires extra components not mentioned in the price?

Both require a PSU,  2x C1 need 2 liter distilled water+200ml antifreeze. And C1  is silent.

But I look forward to Antminer S5, which goes on sale 15 November

Jtoomim, thank you for helping debug firmware issues we'll have problem recreating in Isarel Smiley
Also for keeping the miners in top condition.

Interesting. Did you try NOT to evacuate the heat that miners produce, but instead direct large fans on a stack of miners, so heat is distributed in the warehouse?
This might be a naive question because you certainly have a large density of miners. I am curious because one of my miners is hosted in WA.

Don't the C1 need pumps and radiators as well?

Shipped separately ordered separately from another company... costs?

C1 Batch2 opens sale now, Cooling Kits are included Smiley

SP20 plug and play vs the C1 and cheaper when all costs factored in.

Notice some issues with people and the coolant leaking and issues with failed pumps.

Issue for SP20... noisy?

Most homes in Houston do not have a basement (shifting ground is apparently to blame).
I cannot host mining equipment that produces excessive noise at home, otherwise new SP20 looks good.
I am surprised that mining manufacturers are not trying to accommodate such customers as myself.
Multiple S1 noise was as much as I could handle. S3 is better.
Sptech promised initially that Sp20 will be quiet, but it is not, apparently.

Also i heard the SP-20 is another BOING 747 ready to take off, so it´s made to be in data-centers, the C1 seems to be a lot quieter miner 42db only

price is still too high, there is no roi here.  

Hardware = $800 (including power supply)
Profitability decline per year = 0.1 (only <8% decline per period, very conservative)
Power = 1200W @0.15

Still come back with a negative $ after 12 months. It's basic math, i dont understand why people continue to buy those overpriced hardware, host them, run them, when they wont make any money for you.

Which one requires extra components not mentioned in the price?
@tupsu: look at my math, i did a cost basis at 3.4th (as that means better shipping$/gh) and then adjusted the 4th pricing of c1 miners to be based on 3.5th (similar to 7*s3+ units)
The resulting price was very similar for all 3 options.

@bickelliski: the c1 b2 comes with the cooling kit now. All that you need different from the sp20 is some cooling fluid and a bigger space to set up units and radiators. That's $5-20 depending whether using distilled water or a specialized coolant

S3+: takes up most space, reasonably quiet
C1: takes up medium amount of space, cooling system is easily reusable on a computer or the next gen c2, similar noise to s3 (due to fan on unit and fans in rad), some issues with pump leaks or failures.
Sp20: smallest, best software (debatable of course), better price, loudest option.

Imo, the sp20 is a tempting offer in comparison, but the noise and low buying power of. A bitcoin right now are holding me back. Anyone managed to sub in quieter fans to make this acceptable for living in the same floor of a house with?

Ps: the s5 is total rumor outside of a random magazine advert. I think there will be one soon, but the nov15 date is unsubstantiated by bitmain (outside of a random magazine advert)

Try your math again with $0.10 power - not everyone pays $0.15/kwh or more. Other assumptions like difficulty jumps <6% or increasing bitcoin value also affect the calculations. Its unlikely we will still have a $400 bitcoin in a year from now.

btc/usd increase or decrease is irrelevant to mining profitability calculations, i am surprised as a hero member, you dont understand this basic principal of mining.

Don't the C1 need pumps and radiators as well?

No.  At this time all inclusive. It was only C1 Batch 1 problem.



SP20 plug and play vs the C1 and cheaper when all costs factored in.

Notice some issues with people and the coolant leaking and issues with failed pumps.

Issue for SP20... noisy?
I got both the  leaking miner and  the pump not running. I use one pump of two C1 miners.
SP20 its not only noisy, each of the new software, it will only slow down.
Too sensitive to temperature and power cuts.  A good miner, but too over-tuned.
I look forward to better take advantage of a water-cooled SP20(?)

Imo, the sp20 is a tempting offer in comparison, but the noise and low buying power of. A bitcoin right now are holding me back. Anyone managed to sub in quieter fans to make this acceptable for living in the same floor of a house with?



...
Gone from 1.3x to 1.5x 1.665TH and climbing now, back temperatures gone from 37 to 67°C 77°C!
Keep your room cozy and warm in the winter ...

I am going to have to do something about the fan though, this thing is loud! Louder than all my other miners combined.

If I can't do anything about it I'll have to sell it I think Sad


This is the fan used in the SP20.. beast of a thing!



Damn, fan uses a 4pin PWM Graphics card type header. Going to have to get one of these if I want to try other fan types:

PWM Fan Adapter for VGA Cooler Fan

Don't buy this adapter its a different fitting on the SP20

Good news is that it runs without anything plugged into the header so I'm testing another solution



Latest update (from other thread)

I've currently got two Coolermaster Jetflo 90+CFM fans powered from the PSU, one replacing the internal fan and one on the outside pushing air in at the back.

Not-so good news is thats not enough airflow to keep the unit performing at spec, sweet spot seems to be just under 1.4TH

Temp Front / Back T,B
33 °C / 86,87 °C

But its now normal miner sound levels Smiley

I've got two other fans to try out at between 120-150CF<, still haven't got the connector sourced, its some sort of wire to board molex micro or pico connector, I guess you could solder the custom connector onto the fan wires if you wanted a stock look.

At the moment the wire comes out the side of the lid and to a 4 pin molex from the PSU, not pretty but I'd rather quiet than pretty.

Hopefully will get a chance to test the new fans today, so can update with pics.

price is still too high, there is no roi here.  

Hardware = $800 (including power supply)
Profitability decline per year = 0.1 (only <8% decline per period, very conservative)
Power = 1200W @0.15

Still come back with a negative $ after 12 months. It's basic math, i dont understand why people continue to buy those overpriced hardware, host them, run them, when they wont make any money for you.




Try your math again with $0.10 power - not everyone pays $0.15/kwh or more. Other assumptions like difficulty jumps <6% or increasing bitcoin value also affect the calculations. Its unlikely we will still have a $400 bitcoin in a year from now.

btc/usd increase or decrease is irrelevant to mining profitability calculations, i am surprised as a hero member, you dont understand this basic principal of mining.  

It has a lot to do with it. Let's take a fictional scenario where a miner costs 1btc and over a 12month period produces 2btc while using up $400 in electricity. You effectively break even if bitcoin price stays put at $400 from now to then.

What if bitcoin goes to $1200 (3x value)? At the end of the year your roi will be (2-1btc)-$400. That's effectively a $800 positive roi. On top of that, it's likely the miner could continue to mine profitably at that price for a few more months, maybe another $100 added to the ROI. *for those who say this is why to buy and hold, if you bought 1btc at $400, after the year you would have $1200 in btc, a gain of $800 (bitcoin going more than $1200 would make mining more profitable than holding)*

Granted, an increase like that in bitcoin price would likely result in a larger difficulty rise as 1-2w/gh equipment resumes mining profitably, and other various factors - but the point us that roi is effectively based on a (bitcoin(x1) - bitcoin(x0)) - dollar(y) equation, so the value of bitcoin is very important. Its all a lot of speculation, but so is trying to estimate difficulty increases

if you buy bitcoin directly, you will incur the same gain/loss with regards to btc price fluctuations.  Therefore to calculate if a mining hardware is profitable or not going forward, the bitcoin future price factor is never used as part of the consideration.

Anyone who doesnt understand that shouldnt be buying hardwares.

I stopped arguing with that idiot long time ago. Hes too fcking dumb to understand this simple concept. Infact i say most noobs buying hardware right now are actually expecting BTC price to rise in order for ROI.

There is no btc mining equipmemt that doesnt lose at least 50-80% of its value due to capital cost and electricity during its life cycle.
