Your 90GH/s speeds indicate that only half the miner is hashing - please share the exact status for both boards and chips.  (sounds like 1 is all oooooooo  and the other is missing or all xxxxxx)
try a software reboot via the WebUI without unplugging the power cables. sometimes this helps clear dead chips when a hard reboot (power cycle) does not

whats your power supply? You NEED a supply that has at least 450W available on a SINGLE 12V rail. multiple rails usually mean only half the 12V wattage is available on the PCIe and the other half on the motherboard connector.

pinouts are not necessary - you NEED 'PCIe' connectors. the peripheral 6-pins are usually 2x GND, 1x3.3V, 1x5v, 1x12V and you are lucky it did not blow your miner or PSU to peices by shorting all those connections across one another.

about 13% (in ontario) - still less than most EU countries

if you have a business license/account, you an presumably import for only 5% taxes

there are other possible reasons.

1) check that no cables are loose
2) what lights up when the unit is powered up?
3) is the ethernet cable good? maybe try another ethernet cable first

Every S1 i have has been a tank, and any time there has been an issue a hard reboot (power off for 5min then on) or just a software reboot (via the webUI)has solved it.

altcoins wont necessarily go up when bitcoin does, they got where they are now largely as hedge bets or pump and dumps.

as for doge - dump it now before it is worthless. The mining reward halves many times faster than any other scrypt coin (particularly LTC) and once mining LTC or another scrypt coin vecomes more profitable than dogecoin, the network hashrate will rapidly windle and expose the entire blockchain to 51% attack by a malicious scrypt pool or farm, rendering the currency worthless and making LTC the only valuable scrypt coin, as BTC has done to sha256. Doge will not hold any value beyond 2014

so you are mining bitcoins and exchanging them for other crypto-currencies? Not sure how this relates to the title of your thread

^yes.


When these run out of stock I will make that known. As of now, there are still about 200x 24" leads and 60x 6" M-F-M splitters

a drop of suprlue on the opening of the buzzer should do the trick

same type as the S1/S2 and bitfury units both used. Its a good chip that can handle up to 35-40A if cooled and from a good batch.

MATH TIME

original spec: 32 chips running at 0.75V producing 15.75GH each = 504GH at 390W
you have 2 chips per TPS53355 regulator, 16 regulators total. 480A available at 30A draw

480*0.75 = 360W (assumes other 30W is the pair of 15W fans and the controller)  This was what Bitmain assumed would work

my guess is that either the chips are slightly less efficient than thought, perhaps drawing closer to 420W at 504GH. (420W total, or 560A, or 35A which is a point where not all regulators will be stable). Alternatively, the chip voltage is less than 0.75, thus drawing more amps. 35A draw would happen at 360W, 0.643V.  A combination of both factors is also possible.

gentlemen, start your multimeters!

those splitters are absolute garbage. Ive seen too many where the '18awg' actually has far thinner wire cores.

This is what happens when you use adapters with thin wires unable to carry a load. notice this is an 8pin ATX to 6pin PCIe adapter that burnt up under 200w load, probably only a 22awg wire at best. it even melted into a nearby fan wire. If i didnt see the fire break out it may have ended badly.



The facts should be obvious:
1) PCIe has 3x 12V wires, each safe for about 50W on cheaper wiring. When you use the 2x molex splitters you only get 2x 12v wires, with additional cable length to create resistance and voltage drop.
2) if you connect multiple molex splitters onto the same molex daisy chain you will be putting the COMBINED power through a single 12V molex wire, and almost surely burn it.
3) buy a PSU with enough connectors, or use quality 6-pin PCIe splitters.

I sell 6" PCIe splitters like in my photo that are 18awg and that i have tested to be capable of powering 130W per arm (260W at the female end) without any thermal concerns. Check my signature if interested, because those molex ones are CRAP - DO NOT USE MOLEX SPLITTERS

ive been asked a few times - these are still for sale and selling fast!

hopefully the next step is a better miner.... (rackmount, 1TH+, <130CFM fans)

you can mine some cpu / gpu altcoins, but the income will be pretty miniscule, probably less than the power costs.

laptop GPUs suck for mining, they are confined in a small space so they are restricted by how hot they will get compared to a PCI GPU

no info on the website (i dont have a ups account) about shipping yet, and i ordered 4 units in the first 10 minutes.

I trust bitmain is working hard to ship, just hoping my units come in on friday

a few reasons in my mind.

1) for those who can handle the density a small unit is terrific (and I think in 2015 datacenters will start designing new rooms/racks with bitcoin mining in mind)
2) saving a lot on heatsinks, a larger case, and shipping costs
3) with immersion cooling on the horizon it makes some sense to understand how efficiently the units can be cooled with the least aluminum and airflow, as density of chips in immersion will be a prioity

I have done this with all my boards, plus some pencil modding (v1.2 boards) to achieve about 34-38GH per board. however, it stops mining every so often (about twice a month) and needs a reboot to go back to normal operation

rawdog, you are such a f*cking idiot - you need to shut up and stop trying to scam people into sending money for a non-existant produt to your own address. Sponndolies-tech is making fun of you with their "pre-order to reserve the ability to pre-order" and your quoted scam PM links straight back to that same spondoolies-tech page.

its enough i had to leave a negative trust rating since it seems prety obvious you are trying to sucker others into sending money to your address, but noone is that dumb. (plus you have zero proof you sent or even own 50BTC)

its not a heart, its a dimple in the silver-tin-alloy metal of the coin. As i said already, lealana coins are stamped and the metal itself is often not very smooth. nowhere near the quality of a casacius silver coin by any means

as long as the GPUs have thier own PCIe power, powering the risers shouldn't be a necessity.

keep in mind that the risers often limit the bandwidth of the cards, espescially if you use 1X risers as these will make GPU-intensive operations like games get really screwey with textures and artifacts freaking out all over the place. 16X risers should prevent this issue though (my GPU0 is on a 16x riser for gaming and the other 3 are on 1x risers for mining)

updated the RPi SD card to 1.3.0 and am a little happier. PWM still seems useless, but cgminer seems able to accept frequencies outside of just 300/320/350.

Im running them at 300 now because i switched to smaller, barely-adequate fans (90CFM) that really need a box fan by the unit to cool the outer heatsinks if i want to get to/past 320MHz again. error rate is around 6% now too, which is an improvement
