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.

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.

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.  
2646  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.

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.
2651  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.

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.
2653  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.

I am busy and going to be even more busy in the coming weeks so while I have the Flourinert I need to put this on hold until after the new year.   I have the tank, the rigs (well KNC and Bitfury, HF hopefully eventually), and the immersion fluid I just don't have the time to make the conversion right now.
2655  Bitcoin / Bitcoin Discussion / Re: Fidelity Now Allowing Bitcoins In IRAs on: December 12, 2013, 07:45:32 PM

But in any event, while you or I would rather just store our own bitcoins and avoid the fees, it's reasonable for the less technically-savvy. Additionally, this allows investors to gain exposure to bitcoin through an already-understood vehicle (ie, your CPA will be able to figure out the tax consequences easily). And the fees will likely remain pretty negligible compared to the overall gain or loss, for quite some time, due to the fact that bitcoin will remain volatile for a while; we're still obviously in wild price-discovery mode for a fascinating and far-reaching new technology, asset-class, and monetary system.

If you don't understand bitcoin enough to figure out how to properly store them safely then you probably shouldn't be pumping $25,000+ into them.


That's a pretty myopic point of view. There are certainly people who can easily grasp the economic ramifications without wanting to deal with the minutia of M of N paper wallets and encrypted backups. You need to understand the value of people's time. Someone who has plenty of money should value their time quite highly (we're all mortal, after all (barring some singularity-induced shift in the meaning of life)). Spending days learning how to securely deal with bitcoins (and it would indeed be days for someone not already tech-savvy) just isn't a good use of time for a lot of people.

Also, pay attention to my note about the BIT being an investment vehicle that's already understood with regard to tax consequences. That's huge for the target demographic.

This.  There are plenty of financially successful people who have other people manage their money.  They always have, they always will.  Saying they shouldn't be putting a small portion of their wealth into Bitcoin just because they don't understand it at a nuts and bolts level is just short sighted.  Most people don't understand internet security enough to know how online banking keeps their account safe should they be prohibited from using online banking or engaging in eCommerce?

When people don't know something often the solution is to use the services of someone who does know.

Lame so now they are even telling accredited investors (who generally can do whatever they want with their money, different rules for the rich) they can't invest in this legitimate investment.  I mean it isn't that big of a deal because any high net worth individual could open a self directed IRA with another trustee faster than you can make a phone call but it is still lame on Fidelity part.
2657  Bitcoin / Development & Technical Discussion / Re: Transaction fees too much? on: December 12, 2013, 07:39:53 PM
Version 0.9 will have some improvements to fee computation.  The current client "rounds up" the tx size to next full KB so fees are in increments of the min fee amount or other larger amount set by user (i.e. 0.1 mBTC, 0.2mBTC, 0.3 mBTC etc).  However miners prioritize tx by actual fee / actual size.  So a person with 400 byte tx would pay 0.1 mBTC but this works out to 0.25 mBTC per KB which is likely much larger than necessary for timely inclusion in a block.  

This mismatch will be corrected in v0.9.  Most tx are less than 1KB.  The average tx is around 2 inputs and 2 output and ~400 bytes.  So 0.1 mBTC per KB on 400 bytes would be 0.04 mBTC.  Even without a reduction in fee rules the actual fee paid on this tx would be reduced by 60%.

Thanks for all your efforts on this D&T.  This worked perfectly on my dead machine as well.

Glad it helped.  Nothing like being the first one.  Weirdly the GUI firmware flash option did not work (even w/ ASICs disconnected), I tried it a couple of times.  If it had it would have saved me four days of stress and almost 2 BTC.  Still after getting it to flash by microSD it has been very solid.  Far exceeding my expectations, pretty solidly in the 670 GH/s range.
2659  Bitcoin / Hardware / Re: Swedish ASIC miner company kncminer.com on: December 12, 2013, 06:39:45 PM
Please try some of the smaller pools too then.
The last thing we need is ghash (or btcguild) to become even bigger.
+1 to this.

As a heads up BitMinter is smaller but still large enough to solve a block every couple hours.  It has no required fee only a donation, and it offers perks for those who donate.  The pool also includes all tx fees, and merge mines NMC.  I have been mining it for two days and it has been solid.  One thing I never really thought about is BitMinter announced that to date they have paid out 1,000 BTC in transaction fees alone.  That almost a cool million USD in current exchange rate.  Many pools just keep the tx fees so it would be easy for BitMinter to make a million bucks more by keeping the fees but they don't (and never have).

So , If I'm getting it right , the most profitable way to mine is to sell your pickaxe!
Of , great !

For a limited time only I will share the secrets of my pickaxe revenue boosting system.  We all know that mining gold is getting harder and a pickaxe in January is probably only worth $3 per gigarock.  Honestly it is probably worth less than that but gold miners have gold fever and you can find enough people willing to pay $3 per gigarock in January.  Still is it your fault that you can't delivery until January and thus are limited to only $3 per GH/s (probably 1000% gross markup)?  Now some honest suckers might say "sorry you are going to have to live with "only" $10M in gross revenue for a couple months work".  You know what I say .... that is stupid honest sucker talk.  Don't listen to it for a second.  I am going to show you how you can double the $10M into $20M without delivering more or earlier.  Just free bonus money.

See the first thing you do is promise to deliver the pickaxes in October and mark them up from $3 per gigarock to a much more profitable $14 per gigarock.  Now you might be confused because you already know your pickaxes won't be ready until January so how can you promise October delivery?  It is what we in the creative pickaxing business call "telling your customers what they want to hear to get the moneyz", I have heard that honest suckers might call it lying, or fraud but I wouldn't know. Now this plan isn't for everyone, if you are looking for an honest profit where both you and your customers benefit then you should probably stop reading because this plan isn't for you.  Also if you are in that category want to buy some cheap pickaxes?  

Ok are all the honest suckers gone now?  Good now lets get down to business.  So instead of selling pickaxes in January for $3 per gigarock the revenue boosting secret is to pretend you will have them in Oct and offer them for $14 per gigarock.  We will "limit" this to half a million pickaxes.  We want to make it seem limited.  Nobody want to pay a premium and be at the end of the line.  Now if you get lucky some large group like IcePicking ("always bet on Ice") will do a lot of the work for you and buy about half of those early pickaxes.  Now just sell the other half retail.  Now some of those customers might be cautious so if sales are slow then give away some of the pickaxes for free as "protection".  Hang on trust me it will be worth it, these "free" pickaxes aren't going to make us a fortune at the expense of the customers who trust us.   See if the customers don't trust us they won't buy regardless but if they trust us but are worried about difficulty then the free pickaxes will seal the deal. So reserve 800K pickaxes for the PPP (Pickaxe Protection Plan).

Now you should know that after all this plays out as you know it will, your rep is ruined, so lets double down.   Your customers might not know you can't deliver on time but you do so don't hold anything back. You might as well offer "Dec" pickaxes you can't deliver either!  I mean if you are going to defraud one batch of customers why not defraud two for twice the profit and twice the fun?  So sell off the rest of your January pickaxes as "December" pickaxes and offer a deal of only $8 per gigarock (for a $3 per gigarock pickaxe).  See it is a "deal" it isn't as horribly bad as the first batch?  

Now stop a second and just think about the beauty of it.  We only have one box of January pickaxes.  That is it, yet with some creative pickaxing we have now sold two batches at different price points.   Some customers probably agonized over which was the better deal and they are all coming out of the same box!  ROFL! I mean all we have are January pickaxes, some just have an Oct sticker and some have a Dec sticker.  Smiley   See who says you can have fun making millions?

So lets punch this into the ole pickaxe calculator. The honest promise and delivery in January at a reasonable price nets us $10 million in revenue, but with some creative pickaxing we can still ship the same number of pickaxes at the same time but DOUBLE OUR REVENUE! Don't believe me?  Here is the creative math.  Honest (sucker) January delivery: 3.3 million pickaxes @ $3 per gigarock = ~$10M.  Creative Pickaxe Super Sales System:  0.5 million (promised for Oct) * $14 + 0.8 million * $0 (protection plan promised when we feel like it) + 2 million * $8 ("cheaper" batch 2 promised for Dec) = ~$20 million.

Both methods sell out our 3.3 million pickaxes.
Both methods don't ship until January (or maybe a few days prior).
The creative one makes twice as much money.

Now do you see the magic of creative pickaxing?   Well the bad news is if you want to get technical there is no such thing as something for nothing; this is just a wealth transfer from your customers to you under false pretenses (lawyers might call that fraud).  They never had a chance at getting units before January so $10M extra for "early" delivery is just a $10M reduction in net profit.  With mining margins as tight as they are that will be enough to push them into the red.  See they are paying $20M for pickaxes which really are only worth $10M because ... and this is the funny part ... they actually believed you when you said Oct and Dec delivery.   What a bunch of suckers.  

Of course the only downside is you have to deal with "whiners" who get mad when their Oct & Dec pickaxes doesn't arrive until January. You can't really blame them I mean the high priced pickaxes only make economical sense for the easier Oct rocks.  $14 axe in Oct = profit.  $3 axe in Janaury = profit.  $14 axe in January = profit (well profit for us and massive losses for them).  That is why the Pickaxes were only worth $3 per gigarock in January, but if we had sold them as January pickaxes we would have only made $3 per gigarock and that just isn't fair.  It isn't fair other companies were faster and thus were able to charge more.  I mean $10M with 1000% gross markup how many yachts can you buy with that.  The funniest part is many of your victims did the math and made all the right calculations.  They never would have paid $14 per gigarock for a January pickaxes because they KNEW it would be a loss.   Still with the ole switcheroo you can trick them to.  They have now absolutely no hope of even breaking even.  If you start to feel bad about all the loses your customers are taking and the fact that it was completely avoidable by being honest (and accepting a fair price for a fair product), just buy another sports car, or snort some more premium blow off an expensive hooker. Nobody said creative pickaxing was going to be easy, but a "bonus" $10M should help your guilty conscience.
