Just try both and same Sad

Are you using one PSU or two to power the SP20?

Try moving the pcie cables to alternate sockets and see if the loop that is off changes.

Just check that, is one psu and is ok. No melted pci-e... its miner issue.

I read some back in thread for same issue and changing ribbon cable for both hashing board solve or show if problem is there, but il wait for SP tech answer before attempt open miner.

I try to get answer from their support on skype

Update:
Few restarts later and gentle shaking and we are back 1.6Th
From my opinion this must be bad ribbon cable or bad solder on some connector.
Advice from SP tech still will be appreciated.

I had one where the serial cable (ribbon cable) had one wire that didnt get 'bitten' correctly by the teeth in the plastic connector piece. took 15 minutes to pry the connector open, see the problem, and fix it.

granted - i dont care much for warranties and was confident that my opening up the unit and carefully inspecting the boards, seating, and cables wouldn't cause damage.
try opening it up and switching the serial cbales. if the problem moves to loop 2 the cable is the issue. if the issue dissapears it was a seating problem. if the issue stays in loop 0 you're out of luck unless SPT can help

If the price of bitcoin trends towards the cost of producing it, and the cost of producing it decreases, then the price of bitcoin decreases

I think the price of bitcoin is determined by the market, not by the cost of producing it.

When bitcoin hit $1200 it wasn't because the cost of producing it increased, it was market forces.

The cost of producing bitcoin is raised or lowered to meet the market price, not the other way around. If bitcoin goes up to $1000, miners will see a profit incentive and more rigs will come online... driving up the mining difficulty and hence the cost of producing each bitcoin. If bitcoin goes down, some miners will switch off unprofitable rigs, reducing the cost of producing bitcoin (for the remaining miners). Mining expands or contracts to maintain an equilibrium where the profit from mining is marginal, whatever the market price is.

Miners are reacting to the market price, not the other way around. Very few people buying bitcoin would perform a calculation to see how much it would cost to mine bitcoin (i.e. what the production cost is), instead they look at the current market price.

perception of value vs price.

Diamonds are perceived as valuable . People pay the money for them.

BTC has a perceived value people pay to get it.

Here is 1 example of why BTC can go up in price.

If I were in a country that I was going to leave in a hurry.
I would value BTC a lot more as I do not need to carry it out with me. I can leave the country with just the clothes on my back.

If the price of hardware drops, more is purchased equally by everyone, difficulty increases, and everything stays in equilibrium in an ideal market. You can not alter the supply of Bitcoin (in regards to mining), only re-distribute it based on marketshare of hash power.

The only way for the price of bitcoin to trend towards the cost of producing it would be if hardware reached peak efficiency (no new technology for over a year at a time), mining hardware would become an asset instead of a liability, and the cost to produce would strictly be electricity. We may never see this, although I see us getting closer with every generation.

If you are a seller:
Right now may be a nice time to sell some of your used SP20's for a nice premium...

Right before the next generation is released but after all the new units have been sold out by the manufacturer.

if you are a buyer:
wait until Gen3 gets released and then purchase SP20's at a discount from the big dogs unloading to purchase the best new hardware

Anyone in the SF Bay area want to buy a pair of SP20s?

You should put this under the "Marketplace" section of the "Bitcoin Forum". You'll get some bites over there, or on Ebay.

Unless the price of BTC goes up soon, it doesn't make much sense for hardware manufacturers to design and manufacturer more efficient hardware, and it also doesn't make much sense for miners to buy more efficient hardware.

I doubt we'll see much money invested in new mining hardware after the first half of 2015 unless the price of BTC spikes.

At some point, even the biggest Bitcoin bulls need to face reality and pay the bills.

impossible is to Bitcoin price spikes,because miner must sale all BTC to pay electric bill and bay new gear.Also manufacture must sale all bitcoin to pay chip maker.
and price is now good 230-250$ for 1 BTC is good price.
Also be good if BTC drop 100-130$ or lower because all big miner go bankrupcy,and hardware manufacture closed door for 30-60 days,and bitcoin return to home miner
and i bay BTC for low price and wait next halving.I have money in saving acount whit 0,25% interest.If bitcoin jumpe in one year 5% i am on horse

Bingo , if that price dump in january could have lasted 3-5 more weeks we would be in much better shape as home miners

THIS.

Just mentioned this in https://bitcointalksearch.org/topic/m.10567287

Expect new third-party Shopify stores popping up with used SP-20 bundles for sale (psu/cables included,) boasting under-clocked/over-clocked settings "out of the box". Wink

Honestly unless the price of bitcoin goes substantially higher in the near future. There will be no industrial sales at all.

Reason being is that a about a year ago. You could buy a $10,000 miner, get ROI after 5 months and make a few thousands afterwards with that miner. So for industry reasons buying 50-250 miners at a time was well worth it. Especially in many underdeveloped nations where electricity and labor was cheap.

Now miners are slightly little more efficient as before, but difficulty keeps increasing, and yet price fails to increase.

The same industries are not going to pay $1000 for a miner, which will get ROI after 5 months or so just to make a few hundred dollars profit per miner.

There is a big difference in, buying a $10,000 miner, and making $5,000 with that miner after a year or use THEN buying a $1,000 miner and making $500.

Buying 10 times as much miners isn't an option because it takes up more space and uses much more power and heat.

This is just my humble opinion. Who knows what the future will bring.

Agreed, the mining market appears to be saturated right now based on the current BTC price, which is obvious because the difficulty has leveled out.

Unless the price of BTC goes up soon, it doesn't make much sense for hardware manufacturers to design and manufacturer more efficient hardware, and it also doesn't make much sense for miners to buy more efficient hardware.

I doubt we'll see much money invested in new mining hardware after the first half of 2015 unless the price of BTC spikes.
