Half is better than 0 if your electricity is expensive? Well it's up to you anyway if you want to do that or not.
Yes, it is. But I'm never going to break even earning $1 a week.

WTF is your point, anyway? Are you a BA shill, little newbie?

$2.18 per week

 Shocked

That is like... not even enough for a pack of cigarettes? Wtf is going on?
I though mining would make you rich? 

It would not have made me rich, but if BA had delivered back in February I could have made more than 600$ (~1.3BTC) (w/o electricity costs) at current prices.

I received my X-1 today. And now the fan doesn't spin up.  Angry

After several months of waiting the only thing I can do with it is playing some Android games.  Undecided

And I thought it can't get worse...

I saw on their forum that sometimes the fan connectors are installed backward.  try flipping it.


Tried it already. But it didn't work. The fan is definitely broken. I connected a CPU fan to the connector on the X-1 and it spinned up. Then I connected the X-1 fan (some Cooler Master 200mm fan) to a motherboard as chassis fan and nothing happened.

You should complain! The unit is obviously faulty!

Let us know how that RMA goes.

This time they're really quick. Not even 12 hours after opening the ticket I got a tracking number for a replacement fan.

WoW, totally unexpected.
How is it with that X1, how many procent of you inital investment do you think you can get back?

I think the only way I will get anything back is by selling it on ebay. Even then it will be a loss. As energy costs are quite high here in Germany it will produce even more losses when switching it on.

Did you try to downclock it? It can work at 0.5w GH. at 40 GH/S total Consumption about 25w, if you remove fan and LCD as well place smaller fan like 20 x 20 mm it will be even less. Best i got was 19 W per 40 GH, and it worked without fan. Just don't forget that you can ruin PSU without any cooling applied.

I couldn't make any tests because of the broken fan. I'm waiting till I get the replacement one. But I had planned to undervolt and downclock. I have read the voltage adjustment thread on ecointalk.

40GH earns you $2.18 per week at the current difficulty. You pay just over half of that in electricity at current German prices. So not making a loss, correct, but no chance to break even either. A couple more difficulty increases will kill even that meager profit margin.

Thanks to BA's eternal delays, not a single customer will ever have a chance at breaking even on their purchase price, unless the price of BTC skyrockets again.

Now you can add that BA didn't had enough time to make proper video, add that proper video is improper and cry more about everything else in the world.

But they had the time to design a new 14nm chip?

I have opened a ticket and told them to send me a new fan. I'm currently waiting for a response.

Value will be measured in sats
that removal process can leave pins touching as in the video causing shorting out great solution BA.

This is not official BA procedure it was posted be enthusiasts on forum, and stickied. Now you can add that BA didn't had enough time to make proper video, add that proper video is improper and cry more about everything else in the world. No one can help you if your hands grow out of bottom parts. Whine on.

Why did the BA youtube channel post the video then?

Holy crap, that cap removal vid!  At least clip the leads flush.  I am going to guess those caps have a crappy equivalent series resistance and at sufficient current load they just heat up until they outgas or otherwise ignite.  This sort of thing happens infrequently on system main boards when a marginal cap can't handle the rated load.  Use a solid-core, low ESR part of the correct WVDC and capacitance.  Warning: proper parts cost a bit more.   Shocked  Gads...
