2641  Bitcoin / Bitcoin Discussion / Re: Apparently Bitcoin was one of the answers on Jeopardy tonight? on: December 13, 2013, 05:58:41 PM
how many dollars was the question worth? if it was lower, that means it's more mainstream and known by most households.

THIS

Any answer about the level ?

Yeah I want all the details.  
What was the dollar value?
Did anyone guess?  
Was there any reaction when the correct question was given?

BitChick knew the category so maybe she was watching it.

I wonder if someone has a digital copy of that episode so a clip can be extracted.

If you are bitcoin miner and trade at Bitstamp or Mtgox, do you need a business money transmitter license? I live in USA California.
The exchange already takes care of MT/MSB requirements.  You'd only need your own if you sell directly to other people.

Well actually as stupid as it is by the letter of the guidance there is no such exception.  Don't apply common sense to the law.  As written anyone who exchanges virtual currency for real currency is a money transmitter.  Yeah it makes no sense, it is stupid, and obviously can't be enforced (at least not in any uniform manner) but that is what the guidance says.  This is why FinCEN "guidance" is more like a hand grenade they threw into a crowd.  "Don't worry you will figure it out, and if you don't then you might be breaking the law is we later retroactively decide to enforce it".

That is a nice resource and it illustrates how companies like Corsair are continually changing their lineup.  Today of the non-discontinued models in the HX and AX series Corsair PSU only the AX-760 and AX-860 are made by SeaSonic.

100% of SeaSonic PSU are made by SeaSonic. Smiley  Given the negligible price differences (especially compared to multi-thousand dollar rigs) just buy "the real deal".

The weird thing is that I guess there is a way to send the inputs only without paying a fee.  Apparently though then there is a chance the transaction won't be processed/picked up byt he miners.  I wonder what will happen when the transactions fee gets to be a lot of money (i.e. transaction fee is .0001 but that costs like $50 in US dollars).  Seems like it will make it so people won't want to buy anything small with BTC because the transaction fee is so large.

If I understood correctly the transaction fee isn't set in stone, but rather determined by the community.

Correct.  The MINIMUM fee (to relay low priority txs) has been reduced four times by a factor of 100x.  If the original minimum was still used it would be about $10 today.

I know what it is and how it works, but my router implementation is poor. There is no option to setup the IP address myself. All I can do is select: Always use the same IP address

Then I would say get a new router.  Honestly even a cheap $30 router by any of the major brands (Dlink, netgear, etc) will have solid DHCP reservation support these days.  Just check the reviews on a networking site before you buy one to make sure it will do what you want it to do.

For example:

2646  Bitcoin / Hardware / Re: Swedish ASIC miner company kncminer.com on: December 13, 2013, 04:40:07 PM
I don't think it's possible for this to be correct. In most (all?) modern ATX PSUs, AC is converted to +12V, and the +12V rail provides the input power to the DC-DC converters that produce the 3.3V and all the other power rails, so it would not be possible for the 3.3V ramp to control the 12V ramp time.

I have pointed this out and I agree it doesn't make sense.

The days of rectifying AC into all voltages directly haven't existed for years (probably a decade).  Modern PSU are essentially 12V "engines" with the rest added as legacy support.  This is why if you look at a modern PSU say a 1250W SeaSonic it can delivery 1248W on the 12V rail alone.  All the power is being converted into 12 VDC and then if needed a sub board (and on the SeaSonic it literally is a completely different board) converts some of that 12V to 3.3V, 5V, 5VSB, and -12V if needed.
2647  Bitcoin / Hardware / Re: Swedish ASIC miner company kncminer.com on: December 13, 2013, 04:34:02 PM
Is anyone using Seasonic X1250W supplies for their November Jupiters? I found that after about a minute after bootup (when the Jupiter is about to start hashing), the PSU shuts down. I let the PSU reset itself (takes several minutes), try again, same results. Consistent and repeatable. I tried 2 separate X1250's and 2 separate November Jupiters with the same result.

Obviously 1250W should be plenty, and the Seasonic is a high-quality supply, so I'm not sure what is causing the shutdowns. I normally have the X1250's running 4 BFL SC Singles without any issue, and those take more power than a Jupiter.

I had some Corsair AX860's kicking around so I tried those for the Jupiters. They work well and I haven't had any trouble after 24 hours now.

I am using a SeaSonic 1250W with no issue.   Shutdown is likely over current protection kicking in.

1) The SeaSonic has two PCIe connectors one one cable.  Don't use two on one cable.   You should have 4 connectors plugged into the power supply itself (plus mother board and molex connectors).  That means you will have 8 PCIe connectors use only one from each pair.

2) Make sure the paper clip is making a good connection.  It may sound stupid but you might want to try either a different paperclip or buying a cheap "PSU tester" to ensure you have a good connection.

3) Check the PCIe extension cables.  On one of mine one of the pins was loose.  Loose connection = resistant = higher current to deliver the same power to the ASIC.   Another way to test this is unplug the PCIe extension cables and connect your power supply directly to the ASICs.  I found putting the PSU on the rig lid sitting next to the rig body allows everything to fit.  If you get no trips connected directly and it continues to trip when using the extension cables then one of them likely has a loose pin.

Besides, it's cheap for them to just ship a 4th chip. You still have to purchase the motherboard to run it, and they'll probably pocket more on those than the manufacturing cost of the chip. They could technically sell their motherboards for $5'000 each and still be fulfilling the MPP - there are no terms anywhere that describes the motherboard cost.

The MPP includes the "motherboard" although I think that is a bad name (motherboard implies there is one per system) these are just boards with an arbitrary number connected to a single host.  Essentially HF is shipped an entire complete card (as seen in the photos upthread). The customer still needs to provide cooling, power and case but HF clarified the MPP is for complete boards.

However they don't need 666 GH/s per board.  Remember the completed substrate uses up to 4 dies.  When I asked for clarification on the MPP, HF indicated they have the ability to ship boards with only 1,2, or 3 dies active.   If they wanted to they could pawn off the junk boards which have one or more defective dies which they disable and ship those as the protection.

Given all the lies and deception so far, nothing would surprise me at this point.
2649  Bitcoin / Hardware / Re: HashFast announces specs for new ASIC: 400GH/s on: December 13, 2013, 03:53:33 PM
because they used Seasonic power supplies, which is the OEM builder of the Corsair PSUs that I had connected to the KnC that died and it was the Platinum rated PSUs as well.  When I said that he was saying that it was most likely that I may have used a PSU that was not superior to theirs but when I said that Seasonic BUILDS the Corsair PSUs he did not even know that was the case

SeaSonic doesn't build all of Corsair's PSU.  It also changes from year to year.  The only way to know for sure is to lookup the UL code or look for SeaSonic mark on the transformer (requires opening the PSU).

If you want SeaSonic quality buy a SeaSonic.

Still no word yet that they're shipping us 2x sierras with 5 modules in total each running at 500Gh/s as a result of the lies and deception?



They have already said no.  Single unit and MPP sometime after February.
2651  Bitcoin / Hardware / Re: Swedish ASIC miner company kncminer.com on: December 13, 2013, 06:01:20 AM
I'm a noob here so bear with me I have a static IP but I simply checked the DHCP box and my router is also setup as such and viola..all I know just tossing it out there...anyway ie that was my noob solution to this ..er also my router allows me to lock an IP like the  192.1xx.x.106 etc to my miner also have a standard dlink dir-615 cheap unit with built in wireless...anyway was my noob solution

Exactly.  That is DHCP reservation.  From the miners point of view it is getting assigned a "dynamic" IP address so it boots up and asks the router "what is my IP address" however the router has been configured to always give the same IP address (in this case 192.168.0.106) to only that device.  
2652  Bitcoin / Hardware / Re: Swedish ASIC miner company kncminer.com on: December 13, 2013, 05:59:48 AM
I have it and it works, but the only problem is the DHCP server gives random IP addresses that I can reserve.
I want to specify the IP addresses myself - 101, 102, 103, 104, 105 and 106 as in 192.168.1.101

DHCP isn't the same thing as DHCP reservation.  It sounds like you are just describing DHCP.  With reservation you could indeed set in the router to reserve:
192.168.101 to rig #1
192.168.102 to rig #2
...
192.168.106 to rig #6

the router will never assign any other IP address to those devices and will never assign those reserved IP addresses to any other device.

Most routers today support DHCP reservation although they may use a different name.  Look for a webpage where you can assign specific ip addresses to specific devices based on their host name and mac address.
2653  Bitcoin / Hardware / Re: HashFast announces specs for new ASIC: 400GH/s on: December 13, 2013, 05:49:02 AM
How's the difficulty been these last two months we missed mining due to late delivery and how much will that impact us do you guys think?

From 1 Nov to 1 JAN a 400 GH/s rig would generate ~17.6 BTC based on historical difficulty and the next projected difficulty change on Dec 22nd.    

Now that assumes delivery on 1 January delivery. At the end of December, a 400 GH/s rig will generate ~0.2 BTC per day so feel free to adjust that +/- 0.2 BTC per day based on when delivery actually occurs.

I'm not in the States and hence not familiar with Jeopardy.

If you answered litecoin would you have lost ..... whatever you lose?  Wink

The clue provided is the answer.  The response is in the form of a question.  So it would be "What is Bitcoin?".   

On if "What is Litecoin?" being accepted it probably would be considered incorrect but they do review alternate questions in the commercial break so I could see it being reversed upon review.   Answers are in categories so if the category was something like "Begins with B" then obviously Litecoin couldn't be valid.   

It would have been interesting if someone answered Litecoin.

There is just a slight difference compared to Bitcoin. In Bitcoin you got less than 1000 people holding more than 50% of all bitcoins.... None of the assets above have such an unequal distribution of wealth.

http://en.wikipedia.org/wiki/Nathan_Mayer_Rothschild

Start digging.

It's much worse than in the real world.

Richest 1 Percent Control 39 Percent of World's Wealth

In bitcoin, the richest 0.05% Percent Control 50 Percent of the Bitcoin's Wealth.



Good chart.
The new system is even worse then the old.
Greed is good  Roll Eyes

That is nonsense.  1 address =/= one person.  MtGox cold storage addresses (and just about every other exchange, many eWallets, coinbase, etc) hold the value of thousands of individuals.

Drawing an equivelent chart for dollars would be saying.

The top 10 banks have 90% of the money supply on deposit so 10 individuals own 90% of the dollars.  Obviously an asinine conclusion as the value of the deposits at a bank aren't owned by the bank and even if they were don't represent the wealth of an individual.
2657  Bitcoin / Hardware / Re: Swedish ASIC miner company kncminer.com on: December 13, 2013, 04:20:51 AM
Anyone have any idea why all my Jupiters change their IP addresses even though they are setup for static.
I set them all like this and a few hours later a random miner get a different IP, I change it back, then another miner gets a different IP and so on.

No idea but you may want to look into DHCP reservation as a work around.  Most routers support it and honestly once you get it down you will never go to static IP addresses again.  Many enterprise grade networks use it because it simplifies management.

Set all the Jupiters to use DHCP and then in your router there should be a section on DHCP reservation.  In the router you assign a particular network device (PC, mining rigs, printers, etc) a particular IP address.   

So the jupiter boots up contacts the router (DHCP server) and always get the same IP address assigned by DHCP.  The nice thing is all the config is done in the router so the device only needs to support DHCP.
2658  Bitcoin / Hardware / Re: HashFast announces specs for new ASIC: 400GH/s on: December 13, 2013, 04:16:46 AM
So.. we are starting to get some power numbers:
https://hashfast.com/second-tests/

Quote
Weve got two dies up on this. Right now we are clocking it at 700mhz and .84v core voltage. Its doing 248Gh/s on only 2 dies! Half a Golden Nonce.

Consumption is around 300 watts total and 78C die temp.

So... we are looking at ~600W total for around ~500GH? Obviously the 25% extra hashrate is nice, but I thought we were expecting the total power to be under 1J/GH. 
I guess that isn't going to happen unless we underclock.

So essentially roughly the same power efficiency as KNC, shipped late and at higher cost.
2659  Bitcoin / Hardware / Re: HashFast announces specs for new ASIC: 400GH/s on: December 12, 2013, 10:57:56 PM
Each die has 96 cores, and each clock performs two hashes. Therefore with 2 dies running at 700Mhz should be achieving hashrates of 96*2*2*700=268.8GH/s. This means that either some of the cores are not working properly at all, or they are making errors. At the same error rate, and nominal clock of 550Mhz a hash rate of 194.9GH/s will be achieved, which is lower than the advertised 422.4GH/s. They will need to increase the frequency thus reducing the efficiency of the ASIC.

Well no ASIC has 100% core yield.  It just doesn't happen.  The 550 Mhz is only "nominal" in the sense of it is the starting point.  They are still running under 0.85v which is the nominal voltage for 28nm TSMC HP process so if they can get 700 Mhz out if then there is no real reason to go slower.   Ultimately they will have to find a sweet spot between power, error rate, and raw clock and have the chips target that.  The problem w/ HF was never the hardware, they seem to have some talented engineers.  The problem was the sleazy and dishonest way they went about selling off stock they knew they couldn't deliver upon.
