Ahummmm is this bad news ??
Uptime:2366 | FPGA ver:13 -----TOP-BOARD----- PSU-TOP[NONE]: 0->0w[0 0 0] (lim=1360) 0c cooling:0/0x27000000 LOOP[0] OFF (no PSU) 0: disabled (i2c BAD, btw!) 1: disabled (i2c BAD, btw!)...
A breaker might have tripped. It's also possible that one of your PSUs overheated and got stuck in the overheated state -- that happens on occasion too. If the PSU has a flashing orange LED going, then a full power cycle (unplug both PSUs, wait 30 seconds (this actually matters! Don't wait only 10 seconds, as that isn't enough), plug them back in) should fix it. If the LED is dark, then your PSU isn't getting powered, and you should check the cables and the circuit breakers.
Please everybody read the red part - important! Edit: I will change the configuration that we ship the miners to be 1300W by default. This way the clients will get the units running at safe rate, without failures, but it will take about 1%-2% of their maximum hash rate. After the client made sure the miner is working, and he has access to the miner for a few hours, he can increase it up to 1350W in settings page and let the system learn.

I never said out next product is the SP50. Who knows what kind of goodies we have lined up for you? With 14nm out of reach, I predict 20nm, at least 6TH, lower power consumption, lower price, less noise, named SP40 (with SP50 reserved for the <20nm generation).

I suggest something higher than 1300. A sample of some of the machines we received earlier today, after 10 hours and having stabilized their power consumption: Hashrate, Top max watts, Bot max watts 4559 1345 1350 4431 1340 1350 4507 1335 1350 4535 1340 1355 4458 1350 1340 4470 1340 1345 4568 1360 1350 4670 1350 1340 (record holder, fastest I've seen) 4565 1350 1350 4461 1340 1345 4294 1355 1350 (LOOP[7] OFF (no data on loop) -- fixed by a power cycle, now 4521 1355 1350) 4530 1340 1345 4564 1345 1355 4589 1345 1360 4553 1345 1335 4494 1345 1345 4553 1360 1350 4549 1340 1345 4455 1340 1335 We probably have better cooling and power in our facility than most people, but even so, I would guess most SP30s in most buildings should be able to handle 1320W or 1330W as a default starting point. I actually vote for keeping the starting point at 1360W, because I think that the overclocking algorithm is awesome. But that's just me.

After that the client can change to new number. I don't think this is the reason for DOA PSUs, which we see in about 0.5%-0.7%, but this way I will know if the miner arrived problematic to the client or became problematic after the scaling algorithm.

Zvi, Miners, Apart of the voltage what is a good temperature? At the moment I have:
Temp Front / Back T,B 33 °C / 80,80 °C

Its on high side but still ok. At the back over 85 is high, over 90 i think is thermal shutdown

Probably a world record for hashing density. Extremely low cost and effective deployment method. Behind the SP30s are huge fans. Credit: Cowboyminer mining cooperative.

Looks nice but I'm interested to know exactly how effective. Do you have a total hashrate for those machines?

Having a bunch doesn't improve anything. efficacy is same for one machine - as it is for this bunch. Fact is, he is barely breaking even same as everyone else. Only the guys stealing electricity will prevail.

How many cages did you use for all 37 of them? How many can you shove in one rack? How's the temperature been stable since you have been adding lots of sultry hardware? Don't forget the ear protection. One of my co-workers worked in the head-end (that's what some cable companies call their computer rooms full of switches and gear) and never used ear protection. He lost about %40 of his hearing over time and didn't even notice until it was too late since it happened slowly. And there are signs all over the place warning to use ear protection. Derrrrr.

Having a bunch doesn't improve anything. efficacy is same for one machine - as it is for this bunch. Fact is, he is barely breaking even same as everyone else. Only the guys stealing electricity will prevail. Oh so true! With a network hash rate of currently 216.6 PH/s and next difficulty in the area of 31.5B we can see where this is going. As said before I'm really impressed by Spondoolies-Tech and their products, unfortunately not even at 0.55 W/GH (off the wall) it's possible to reach a positive ROI any more if not having free energy (and again and again, THERE IS NO FREE ENERGY, period!). We need the new tech, more TH at less W and lower price! It's all going to hell too fast, I'm really wondering how large mining farm are going to make a profit considering all costs involved with decreasing mining reward and current low FIAT exchange rates.

I'd hate to be the one that paid that invoice. If he's not getting free electricity it is a tough pill to swallow. UNLESS Mr. Cowboy got such an exceptional price from buying so many. It is kind of cool seeing so many of them together. He must of took out all the marijuana plants and lights and started a bitcoin venture.

It's all going to hell too fast, I'm really wondering how large mining farm are going to make a profit considering all costs involved with decreasing mining reward and current low FIAT exchange rates. without mining bitcoin is a boring exercise, like investing in stocks or mutual funds. It will be not a very interesting proposition. I think that, if btc price does not improve, many people will be out of mining by Jan, Feb. Cloud mining is a joke that is designed to take money from people who cannot count, so it is not a path forward. Edit: as soon as I posted this-news re SP-20 (Jackson, 1.7Th ) appeared on cryptocoinnews (ZeroBlock). Not here yet, Guy/Gadi. 1100 W, so i can repurpose my evga, 4PCIe connectors, just 60dB. Price has to be right, though.
