Its funny to look at that then go to the activemining thread where they promised 170TH but cant seem to pass 100TH because of cooling and power issues. All while using hardware they produced/sell and is 20% more efficient than the dragons

that dragon farm looks sweet, and is truly the new ASIC porn

ugly POS
1) uses USB port
2) uses 3 more USB ports
3) this wont stack vertically or horizontally with all the wires coming out at terrible angles
4) surely the back heatsink plate is obstructing enough air thats its causing excess fan work/noise (?)

zvisha has been helping me out the last day or so with troubleshooting and getting some temporarily-lost stability back to the miner, however, i am still having some slight issues:

1) fans at 70% used to be fine but as of today sounded terrible. ive soundproofed somewhat and reduced to 60%, but its still a similar volume to what an unmuffled 60% would have sounded like last week. Without a dB meter i could be crazy though - getting this in a DC is top priority. the unit also has very slight vibrations that go away if i put a few pounds of pressure on the middle back edge of the lid.

2) The unit seems to always have a 10% or higher (right now, its about 16%!) error rate, even after hours of operation, temperatures of 26/77C, and most of the chips at 77C with a few at 113C.  Miner says 1.41Th while the pool says 1.25-1.3TH.  What is the accepted/error ratio for others?

the product is excellent, but it needs to be operated in a datacenter or somewhere that the fans running at 90-100% wont burst eardrums. I would really love to see the SP10 fit in an SP30 case to better dissipate the heat and use bigger/quieter fans.  Most DC racks cant handle anywhere near the 40-50kW draw that the SP10 and SP30 models enable

psu is about a 10-15% efficiency loss

I disagree. at-home miners have a few big advantages:
1) free space (garage, basement, shed, etc). larger miners have rental locations and costs as such
2) "free" internet
3) 'free' wintertime heating (a large location will still be fighting to keep cool even in the winter)
4) no oversight or employee costs

IMO, mining at home can be more profitable than it is running a medium-sized farm. Ive personally had to move 8.5kW of my gear into a rental agreement to access enough power and space to run it outside the house. To go any bigger I am looking at a $500-1000/month rental elsewhere plus whatever costs are involved in adding AC/wiring/transformers to make it a useful space.

a lot also comes down to power costs, and anyone who pays less than $0.15/kWh has significant advantages over miners in many countries and US states

thas more than 3BTC - no way

Several significant hashrate drops, two in the last two days. The farm that was originally proposed as 170TH and trimmed down to 120TH promises has been averaging less than 80TH for hours now and 100TH has not yet been passed supposedly.

I don't se why not, but it may not be until next batch.   The Y-splitters may act well as extensions

not many though.

IMO the SP10 and SP30 units are built more with datacenter than spare bedroom in mind. They are loud and create a lot of heat, in fact the 1200W draw can be more than what the majority of PC power cables are rated for (10A).  If you are able to operate these at home, it may be worth the work required to either install a new 240V circuit for your equipment or to even simply swap an existing 120V circuit's (with only one dedicated outlet) breaker and outlet for a 240V one. Wiring can remain the same in most cases.

208/240V is more efficient and puts a lot less strain on the power supply - the sondoolies machine is a long-term investment/installation.

I I just got pricing for a new batch of 24" 16awg wires with 0.75cm stripped ends - in bulk I can do 50/$90 or 100/$160, plus shipping (around $25 4-7day ground or $45 and its 2-3 day express, but i would have to confirm the exact weight/cost.  I can probably be reshipping next week, likely by tuesday.

I can also order Y-splitters made with 18awg (M-F-M) for 10/$25, 25/$40.


I am also selling smaller quantities at the same pricing model as the 30cm/1' cords, so consider the extra 1' length a feature of having a more dedicated bulk customer base

Z- : BFL         laughed pretty hard at this, while grimly knowing it is true

try 8kW... Im trying to figutre out he next step

the S1 will run fine without that capacitor, but you may need to treat it special in order to get it to power up okay.

1) power up unit normally.
2) if there are a few non-working chips (there likely will be), reboot the miner but leave the PSU on
3) the miner will reboot and the power will be stable enough in other capacitors that all the chips read up fine.

I have a unit missing that cap (i found it in the box after) and its running fine stock without doing any repairs just using the above method

8 PCIe ports? why??  Shouldn't this board only require ~700W?  That could be delivered by 4 PCIe sockets quite easily, and the current layout will make unplugging the cables a PITA

its close to $200 to ship the SP10, and realistic values are closer to 1.25TH on 120V and 1.4TH on 208/240V. It is also the volume of a blow dryer when running. The design itself and the efficiency is terrific on it though   DC usage with 208V is ideal

the AC is partially a dehumidifier - it may only have a small effect though.  However the heat of the shed should ensure any moisture stays in the air and does not condense at all.

eligius is in fail-safe and seems totally down.  try adding a backup pool in case its your pool and not the miner

yes, virtually having your business entirely halted by the MSD (at least short term) is only a small bump. Like DTS says youll certainly be shipping products on time and operating a 500TH farm any day now once you pay out hundreds of thousands (millions even?) to the investors you shammed and pay fines to the state because you are a known repeat offender in terms of shady business practice.

IMO theres a chance that the MSD will fully dissolve your companIES (VMC included) to refund your customers and pay your debts. They can clearly see the shell game you have played (particularly with VMC != ACTM    and shares != direct ownership of the IPO). In the bitcoin world it IS possible to have extremely concise and simple accounting/auditing but ACTM has not done so. Financials will soon be two months late, nobody knows how much the farm cost, how much you lost to eASIC, and how much you lost on mtgox. Even then, expect to provide full and acurate accounting of these losses so that it can be clear that ACTM/VMC funds were not used on exorbitant self-income or directed into personal accounts.

back up to the top now that BTC is surging and these coins are becoming fewer!  *with every coin sold my price increases*
2.3BTC - It can be any from the photo while available. All 1Ag6 batch  full album here http://share.pho.to/5rC0W

   

pleas note that the paper says "Tuesday, Apr 29". This photo was taken a month ago but coins are still available

power supplies are more efficient on 200V or higher - thats why 1100W is the limit of 120V but 208/240V can provide 1250W. This extra 150W is needed to clear the gap between ~1.3Th and 1.4TH.  even then 1.45TH+ is likely not achievable without setting fans to 80%+ and/or using a cold intake temperature
