I still never received anything when I won the auction listing last month.

He added $360 shipping costs per unit to almost double the winning bid (would still be an okay deal for me) and then insulted Bitpop as an escrow provider and virtually stopped paying any attention to my requests for payment info.

After a negative trust review he contacted me to make it right, basically offering them at the price I bidder, but almost a month later (ie: not a good price anymore). The alternative was that he would sell me asicminer tubes fit into a rack-mounting case for the price of the tubes, the case, shipping, and what was likely a $100 premium. Total bullshit business model

I never gave him a dime, but i support everyone in getting back what they are owed. Hopefully the BFL fraud investigation will spread to other fraudulent companies like amt and activemining

With every new sale it's one more customer to look after. They probably get twice as many emails a day now than they did a month or two ago.

Imo the hardware and support is excellent, and the team knows what they are doing. Most of the negative posts in this thread are from people looking for refunds on preorders

I need some advice / assistance.

I have one of the first batche pairs of rk-boxes that are supposed to do ~900GH, but over the past 2 months ive only gotten ~650GH on average for a few reasons:
1) I regularly see intermittent periods of downtime, or it needs a reboot because it keeps doing software reboots every 5 minutes
2) it will only recognize 5-7 boards of the 8, usually only fixed with a power cycle.
3) even when running fine, its about 880Gh with 7-10% errors.

Ive upgraded to a class 10 SD card after a recent power outtage killed the class 4 (please stop shipping class 4 cards for mining equipment - put $3 more into a class 10 that will survive power cycles), but its had no effect on the stability or mining results.

What can i do to fix the problem? Its a massive pain in the ass because this unit is both my least power-efficient and the most irritating to fix.

Are there any ways to reduce the W/GH? has anyone tried undervolting to get <1w/GH?

of course its possible - look at how sales were done this time with each component being priced individually. Shouldnt be any rason not to build a compatible BE300 PCB

The chips could likely be placed much closer if the overall thermal distribution is the same.

+1. 220V can run safely using 120V outlets/plugs and is often more cost-effective to use than the $20-100 alternative of specialty NEMA 6 equipment and adapters.

The real risk is absent-mindedly plugging something 120V in and overloading it. A coloured outlet with a warning label in the mining farm should be pretty safe from this concern

or....

keep stirring the pot and keep calling woodlaw or other law firms to keep the pressure on ken.

keep the fire burning under his ass - dont let him sleep well at night, dont let him scam anyone else, and put him in jail with all the other scum that prey on others (pedophiles and rapists)



ps: ken did not just fail at a company, he failed repeatedly, did not keep promises, halfassed everything, obscured the truth, owned his own mining equipment on the side (737GH of avalon gear, anyone remember that he had that from virtually day 1?). Financials were due months ago, but all we saw were delays and a mining farm that couldnt pass 50% of the promised capacity.

at a $400 BTC, I imagine the cheapest farms cost about 8c/kwh (all costs considered) and will be hitting the ceiling for 2w/GH right now, and very soon the ceiing for profitably running 1w/GH gear.


industrial power can be found for $0.03-0.06 USD/kwh in various areas of the world. Pair that with locations having very low rental costs (rural) and negligible internet costs and a barebones staff.

with winter coming though, we could see a slight resurgence of small-scale miners heating thier homes or mining in places where they dont pay for electricity. I personally will be relocating a lot of my equipment from a small office building (i am colocating in a corner for free, just paying electricity/cooling) to the basements of myself and a few family members so that the heat produced serves a utility and saves me money by saving gas heating bills or replacing existing space heaters.

I agree that 100 is extremely unlikely since this drop is based on fear/manipulation rather than a failure in the protocol.

300 would be the bottom i expect, the charts already gone from a waterfall to a vertical drop, and i suspect it will bounce hard this afternoon somewhere between 300-350 and get back to 420+  by the evening

what prices and when may these become for sale? Looks like a simple and efficient design

first off - how the hell is not having an upgrade kit announced yet screwing over customers?

secondly, the S2 runs at 1w/GH, which is still very profitable at this point (despite the fact that 6 months ago most people thought theyd be doorstops by now). There is at least 2-4 more months of utility at 1w/GH and beyond that its quite feasible that the S2 can underclock/undervolt to 0.9W/Gh or less.

Theres no reason to sell an S2 upgracde kit right now because the only people who would buy them would have some way to still run the S2 boards without case/backplane/controller/screen - or just be willing to throw money away by not utilizing 1w/GH hardware

Bobsag was stating that you could install an outlet such as an L6-30 on any circit with a 30A live, 30A live, and Ground where the difference in voltage across the live lines is 30A of 220-240V. As far as I know this sort of direct wiring from the fuse panel to the outlet is no different on a european panel than it is on either a 2-phase 120/240V or 3-phase 120/208V breaker panel.


however, you likely could not just swap an outlet or multiple outlets on an existing ring circuit for the reasons you brought up. Unless im missing something?

3BTC is high i think.

if its drawing:
1.0kW -  2.8BTC
1.2kW -  2.6BTC
1.5kW - 2.5BTC

assumes power supply is included

This is my thought. I don't know if they'll under clock enough to run on the 1050w supplies like before, but 1200w supplies are reasonably common and we'll priced enough that 2th/1.2kw seems like a fair target, and if psu is included it would justify a 2.4btc price tag

1) 13a at 240v with 20% headroom for 24/7 use and surges gives about 2600w usable. I would not load anything over 2800w or you'll trip breakers or risk fires inside your walls.

2) PDU doesn't give much real benefit unless using with 30a or specialty outlets. Just use the typical 13a style of outlets and wiring, or 20a version if possible. Use normal surge bars that are far cheaper than a $100-300 PDU and take way less space.

I live in toronto and work in markham - would be interested in making a deal

gonna need more unique proof, since what im seeing appears to be racks of SP10 units, which are closer to 1w/GH efficiency and worth a lot more than 'free'

Batch has been in for about a week, but haven't had a whole lot of time to update the thread properly

Ive put some fixed prices in place for common quantities, to help streamline the order process a little since I commonly get emails requesting quotes. If you are interested in larger orders I am happy to create custom quotes

  SPECIALS:
4 cables and basic US shipping = $23
8 cables and basic US shipping = $35
16 cables and basic US shipping = $50

could be a PSU issue - 3 boards should only require ~520W, which is about 70% of what the PSU should handle. The fact it cant handle 4 boards isnt surprising though.

^sounds like a good way to go, the tplink would be a lot cleaner of a build than an RPi and even cheaper.

One easy way to do this may be to compare with the U1/U2 devices, which hosted a singular chip and acted as a UART-USB bridge. My understanding is that the chips communicate data in a singular chain, or at least as 4 chains per PCB.

undervolted boards could likely run with airflow only and no heatsink, making a restored S1 system very cheap to build as an open-air if many boards vcan control together
