And I'll say it again Double SHA256 != DoubleSHa256. A Bitcoin block is a hash of the hash of the block header that is lower than the target difficulty.
Doing it twice, is hardly a fundamental deal-breaker... That is like saying you can't multiply, because this uses double-multiply... C*(B*X) OMG new technology.. we can't just SHA-256 it twice... Seriously... Which link was "not a chip"... The first link IS a chip, and a process. None of those were, "just ideas", they are used in cryptographic hardware. ASIC's that "only do SHA-256" are new... because no-one would limit themselves to that specific of an insecure technology, when just adding a few more commands, in silicon, has no penalty. I only linked those, of the thousands I found, which interested me the most. The point was, that they already have patents and rights, to much of the hardware which, in part, is being used on the ASIC's being developed now. Items that could already be in users hands, instead of waiting for all these potential devices to actually be "created" from scratch. (Which, it is safe to assume, may even all fail, or be insufficient to adapt to any form of "modified" bitcoin code, which will eventually be made. As it stands, these potential "cracking" ASICs coming to our hands, are going to be used for that, at some point. They have a brute-force ability above any GPU, and equal to a super-computer, for such a modest SHA-256 encryption. Which, by the way, is not hard to "fake" valid checks, when you simply have to modify the package until it results in an equivalent HASH. That is how viruses inject themselves into system-files, and avoid detection after injection. They just alter insignificant values until a valid hash is returned.) This system will only last so long, before it has to be, "trimmed" and re-secured with more non-standard encryption. Don't forget, "crackers" don't have to do a "proof of concept", they only have to bash until they find an acceptable hash with a modified chunk of hacked data. (Essentially creating or destroying coins, which-ever attack they are going for.) And if ONE person/company, producing the "large chunk" is holding the longest chain, invalid, but the longest, that it keep re-validating... they control the banks. (Which will be those developing the ASICs now, with our dollar. You don't seriously think they are going to "give us", a majority of a market they know they can consume, do you?) Fine, you can't, and have no actual idea how to... so why answer? As for "archived posts", If I wanted to read old dead posts, I would have searched. Is there some rule, "one original topic per forum?" Just because someone suggested it once before, and nothing was done, why should I be damned to posting a new, up-to-date topic? Get a better search function, and I might actually use it. Then I will revive every previously buried topic known to man. Ok, I am bored now... Back to my corner of the net. I'm not scared, I go where the money is... No more money here, I just go. I still have not actually seen a functioning GHs rig ASIC yet. Only that one, which is buggier than an e-machine, which is still a power vampire. And now he wants $8000+ for it... lol... Defeats the purpose, really! |

You are going to wait until they have shipped before you collect? I ask that because that is not "proof of ownership", a jpg snapshot of an order...
Are you one of the many who "got a refund", and thus, that order is not actually valid?
Just asking. I am not interested in paying 2x more than the existing price, for a device which may come in two months, or a year, or ten... But to those who may actually be interested, that information about actual proof of "current order standing", of "an actual confirmed order recipient", would be more bennificial than a photoshopped and altered image of a screen-shot, which is worthless as "proof". And who is "John"... and since it is YOUR sale, YOU should pay... Why would you demand WE pay for YOUR sale? It is not YOU who needs OUR trust, it is the other way around, my friend. Your expense.

Odd, I can't edit the first post... Should say four domains, not two...
|
|

|

I have two domains up for grabs...
First, checking to see if there is interest. Simply say which one, and throw-up an offer.
WamPow.com (WAMPOW), WAM POW... You remember it, or else! It's the white-mans, "Boo-Yah"... lol.
Dabify.com (DABIFY), If you dabble a little here, dabble a little there, then you dabify! Dabify yourself...
MYeLIST.com (MYELIST), Get listed on "MYeLIST", share it with others, find it in MYeLIST...
CURBay.com (CURBAY), Before you put it to the CURB, try listing it on CURBay...
Just trying to get another rig before the ASIC's come and leave me in the dust. So this is essentially a pity-donation, with the offer of my website-names. (Could even include hosting too, as they are already setup on my servers. As long as you don't mind shared-servers. Uses c-panel for access.)

So are you going to allow some form of escrow service for this exchange?
For all we know, you are that guy who owns the website/investment-group... What proof will you provide of your identity, and what proof will he provide of his identity and ownership of the accounts?
Hmmm... you made an investment... and lost... (Hacked... whatever, they didn't have "secure" accounts or arrangements or protections... thus, investment lost. That is the same if you invested in a real business, and they left the front door unlocked... Still your loss. You need a lesson in investing, if this was your choice of investment.)
I don't know why all these places have access to actual client-data on the same servers that run the websites... That is a poor business model. The clients data and account funds, and other things, should have no physical connection to ANY web-interface. It is just an interface for passing data. If hacked, they can't do anything, because the data isn't there! But I digress...
I do hope you are able to get some of your losses back. If you sell your losses... I hope those who purchase your losses, your error, your bad decision, your bad investment in an insecure investment, will ALSO not face the same losses after you have gotten your payments. Obviously, if he is thinking of operating again, I assume he will still be using the same horrible system, with better security, but that won't help the system, just delay the inevitable again.
The one thing you have going for you, is your posts here in the forum... But it is not YOU we have to trust, it is the OTHER GUY... (Oh and if the "law" said he HAD to repay debits, then he HAS to... Criminal or not... It could be another person who assumed the debt, and is paying to "keep the business alive", or perhaps, that is how the business actually operates, or intended to operate... You got there just in time... after investing more and more and more... then boom... time for him to cash-out, or he just lost it all, and "said" he was hacked. You know, those ASIC's were taking orders at the time... They just didn't release in time... Thus, the "loss", when everyone tried to cash-out.)

P4man you should make a pre-order list.
I probably will, but certainly not before I ordered everything myself and have a firm shipping date. Otherwise Id have to call it "butterfly coin"  . Ouch... Still... I am ROTFLMAOSHISMS (so hard I s**t my shorts) Not funny,  I have faith that they will release the butterflies soon... right after they have built the pot for the leprechauns to fill inside their own house at butterfly-labs. 10 for them, one for us... they win! Welcome for the investment, thanks for giving us the scraps! lol. |

Minted BTC: (Original denomination), (Your identification/name/coinage-name), (3-letter Country Code), (Year) The new standard for "physical mints".   (Makes them easier to collect in the future too!) EG... 100 mBTC Bit-O-Bitcoin USA, 2013 As opposed to... 100 mBTC Bit-O-Bitcoin FRA, 2013 or, as opposed to... 100 mBTC Rasha-Denominator FRA, 2013 As for my "names".... - Bit-O-Mint (Little freshness in the digital market) - Bit-O-Bitcoin (Just a little of something bigger) - Hash-N-Stash (It was hashed, now stash it away) - Bit-O-Byte (Geeked play on words... You bite into gold goins to test if it is real, in the old days.) - Scratch-N-Cash (Unlike, scratch and attempt to win... like a lotto ticket... This is a sure-thing) - Lucky-Coin (Good or bad, it is still luck) - Spare-Change (Can you spare change? Another play on words... Got change to spare?) - UNO-Momento (One moment, one momento, the memory, this memory... More word-play...) - Unvirtualized (Um, out of the virtual world, into the physical world, into your hand.) - SHA-KING (Shocking... Sha King... ) Ok, all done... If I win, PM me, or send what you wish to donate to my wallet. 131cttnLM9YFVo2Tg51oWqm7Jngj5Q3ySd I love this kind of thinking... |

I feel for those who are stuck in Zimbabwe... Completely abandoned by the government and by the thieves who destroyed their whole economic system. Such horrible corruption there.
Best thing to do, for them, is find some resource they can offer out-of-country... since there are too few with valuables there, who are not restricted by the government.
I would say, in light of bitcoins, some kind of technology service, using as much recycled tech as possible. Art, data-processing, data-transcription, identity-conformation services, web-hosting... Things that "don't have to be shipped", can be done online, and do not require much training. They have to think like the Chinese...
They are all still trying to produce physical things, without physical supplies, and no way to physically export them, in most situations.
Electronic services are instant, and don't often care about culture or language limitations. They are the grunt-jobs which help form the components of larger systems. Like the "identity-confirmation", which just requires them to be able to "See", and "confirm" or "deny", similarity or exact matches.
But if anything, they should all try to move-out. (Which I know they try, but get stopped and are forced to stay, in many locations.)
Most of those locations need solar-cells, well-pumps, water-filters, bottled water, nutrient bars, salted trail-mixes, breads/grains... But physical goods get squandered at the borders, taken, and re-sold as exports to other places, by the government and officials.
P.S. This is less noticable deep in the "tourist" cities, where only "tourists" are allowed... Try holding up a camera outside the city... you will be "detained" and interrogated, and treated like a criminal, just for "recording" what you see.

SHA256 != Double SHA256.
Um... There is no such thing as "double Sha256", it is still sha256... and solved with sha256. You could use three, and call it triple... but that doesn't make it TripleSha256... if it was "double", it would be SHA512... Thus... stop applying "laymens terms" for post-process encryption methods that have no bearing on the actual processing/hashing component. I'm talking out my ass... Just throwing dust into the wind, to see if I can create a dust-storm from a hand-full of nothing. Is that like double 128, because we do it twice, makes it 256? (Dur, hum, dum) Someone came from the /b/ boards, right into the stereotypical pool of copy-cats... Trend much? |

Wait, can't our network cards also do sha-256 encryption internally... and our sound-cards... and our video-encoders... Why stop at just GPU's... I am sure the processors also have dedicated sha-256 commands too... why are we trying to code this stuff manually, with raw-code software? The hardware is there already. Just because OLD code from CPU "failed programs" from "unknowledgeable programmers", were using copy-pasta code that had obvious limits... Here is another multi-range CPU dedicated to ultra high-speed encryption designed for "gigabit bandwith" encryption. (Like our network cards also do.) https://www.power.org/press-release/amcc-powerpc-460gtx-increases-performance-and-bandwidth-for-networking-and-telecommunication-applications/ |

Seems that the technology for these specific chips is nothing new... http://www.cast-inc.com/ip-cores/encryption/sha-256/Oh, look... a real company, with actual contact information, with actual ASIC products to sell... Who would have imagined? Why "develop" your own chip, when they already exist... Hmmm... I smell future lawsuits here... Can anyone say multi-national copyright infringement? So, who's game for laying down some generic schematics for a standard USB interface that uses standard serial-usb single-connect chips? Anyone? |

All these ASIC's will do, is spend 90% of the time sitting on their thumbs, or verifying what the greater majority of the GPU's have done.
If they even survive... If they are doing nothing 90% of the time, because there is no more work to be done... What can they actually make?
It is the "volume" of workers, not the speed of the worker, which wins this race. CPU's died because they didn't have volume or speed. GPU's have volume and speed. ASIC's only have speed.
They still have to pull from the same pools as everyone else, and while they are solving "ABCDEFGHIJKLMNOP" as one fast chunk... the ones who solved "A" and "B" and "C" and "D" and ... ... ... "P" first, still win.. The cores they run are still slower than GPU cores. Since they are not multi-million-dollar companies who actually figured-out how to build a real chip, with fast cores.
Not to mention all the "hate" they will take, being targets of those with all these GPU's that can't cut-it, and decide to use the power they do have, to thwart the ASIC connections and pools and chains...
The issue I have with ASIC's, is that the manufactures of them, are hording our money to build themselves super-computers, and giving us a few crumbs in return (selling of x-number units, while they keep x*10-number of units for themselves, with our money.) Just imagine them "making thier own fraudulent chains", and being used to thwart all the real chains, since they are making them faster!
LOL... OMG, I must state my "Concern" with 256-bit encryption... I feel I can no longer use bitcoin, unless I have 512-bit security now... OMG ASIC fail! lol... Free 1:1 conversion to the new 512-bit encryption... GPU WINS! For the people, by the people... not for the man, by the man, at the cost of the people...
It is the peoples currency, and the people have spoken... demand 512-bit... or at-least 257-bit! lol... one bit at a time... die ASIC DiE

Switch to a 220v setup... It runs the same power at half the amps. EG, less breakers required, twice the available potential. Not to mention, 220v PSU's are about 5x cheaper!
If you have them setup 220v to a circuit, you MUST label it 220v, and then simply change the switch on your PSU to 220v and plug it back in. (Don't flip the switch to 220v on a 110v line, you will fry yoru PSU as it "tries" to regulate with half-power. Had to say it, because some noob will think, "Hey, lets just flip the switch, and it now runs at half-power!", no, well, yes, but that kills it, without the other half of the power. It only makes it more efficient and draws less amps/heat.)
Since you are asking from a "power" concern... and logistics...
The AMPS on a power-bar are a safety for the GAUGE of wire within the cord, and the internal circuits (if any), and the length of wire used... based on "standard power and draws", from UL records/laws per "individual outlet"... You will not find a "legal", 20A breaker on a power-strip, that is UL,CA and actually "insured", but it may have a nice warning about fire-hazards stamped on the plug. Those are for "intermittent" use, in a consumer-world. (The 20A-30A breakers.) The "Cord" may be UL,CA approved for 30A, but the breakers will not, for 110V. 15A = 1650Watts. 20A = 2200Watts... at 110v... many times the electric company reduces power to 95v to "make more money" from your meter, which measures amps... That turns a 20A source from being 2200Watts at 110v, into a 23A source at the same wattage of 2200Watts. Thus, "tripping" 20A circuits in the summer-time, but not a 25A circuit, so it goes undetected most times.
As opposed to 2200Watts from a 220V line = only 10A, not 20A.

Does your PSU blow out, or suck-in?
What other fans do you have running inside your case? Are they blowing in or out, or push-pull?
If you have heat-piped cards... (seriously), flip your case upside down. Heat-pipes are useless upside down. The vapor has to fight gravity, through the wick, and most of those setups blow the heat right back at the GPU it is trying to cool. Thus, just circulating hot air inside your case.
I suggest, if your PSU is Exhausting air... then only have one or two fans, near the bottom, to push fresh air inside. Only exhaust should come out the back, fresh from the front/bottom, near your GPU. If your GPU's don't exhaust out, then you might want to add one exhaust near the GPU/CPU area, to vent out the back, but keep the fresh air blowing directly at the GPU. Your CPU isn't doing much work anyways.
FYI: Good tip... Fill dead-space in your case with foam. The lower the air-space, the less "turbulance", and the more "flow" across the components. (That is what makes Blade-servers function so well. Air passes over everything and instantly exits, no swirling and lingering and circulating inside, retaining heat.) Not to mention the noise-deadening quality of foam. You can then use quieter fans too.

I'd still recommend dropping down to 7950s. When price is such an issue they are more efficient per $ per hash. The only reason people do go 7970s is because density is a factor.
Be wary of going such a cheap case in that you will probably have to buy 2 or so 120mms fans.
Thanks, you are right, I made my calculations with the 7970's I can hash up to 1400Mh/s if oc, with the whole system price of $1100 gives me 1.29Mh/s/$ spent. With the 7950's I can hash up to 1200Mh/s oc, with a price of about $930 for the whole system it gives me 1.27Mh/s/$ spent. So it's not a big difference it saves about $200 dollar, and I added a case with 3 fans. OCed, they pull a constant 288W each... If you can handle linux, go for the USB boot... If not, get a cheap 32-64 SSD that is older and used... they draw 2-4W running, and 0.2-0.8W idle... unlike a HDD which is closer to 18W-80W... Also, if you do not have the CPU and MOBO yet... get one for a pentium (T) format chip... EG... Celeron G650T (Not G650)... the (T) = "Low thermal design", thus, 7w-35W idle/operating as opposed to normal chips which are 18w-85W. (Eg, smaller fan for cooling, less power draw, more power to your GPU's) |

I wonder if the crossfire adapter comes with the graphics card.
It isn't needed... unless you are going to "play games" and try to use both cards as "one card"... Even then, it is a wasted connection, unless you have an ultra-HD resolution. |

You can only use 4x on that board. There is no such thing as a PCI to PCIe converter. PCIe is 8 PCI slots. There is no physical possibility of PCIe ability from a PCI. You CAN turn PCIe into 8x PCI slots...
The most 7970's you can fit on any motherboard, is 8. Only 4 for dual-core cards. (Windows/Linux and hardware has limitations which only allow 8 cores to be assigned/operated/allocated.)
The only "issue" is that you will be consuming a great deal of useless power, in the process of hashing. 1/5th of your consumed power is dead-CPU wasted.
If your rig, without cards, consumes 250W itself... adding four more 250W sources of power will total 1250W, which will peak over 1500W at times, and stay there if OCed.
What you want for a rig, is one that allows the most cards, and operates at the least power.
For example, my rigs can hold 6x 7970 per motherboard, with a total wall-wattage of 35W, with no cards running. Populated, and running stock, it consumes about 1280W, with the 6x 7970's and two PSU's for power. (Note, all fans run on 110v, not PSU power. Fans at 12V are a waste of power and just add heat.)
I could save a little more, running Linux from a USB, but I enjoy windows on my SSD, which only consumes 2W running, and 0.2W resting, where it stays most of the time.
HDD consumes 14-55W, on average...
That CPU consumes about 35-85W, on average...
That ram consumes 5-15W just to keep it "up"...
All your fans, I am sure is another 20W of wasted power and added heat...
This is my "baseline" system. (Roughly 10% of consumed power is wasted on the CPU-waste per 6x, as opposed to your 4x with 1/5th cpu-waste power.)
MOBO: MSI Computer Corp. (Z77A-G45) DDR3 1600 Intel LGA 1155 Motherboard

Cool! Thanks crazy! Power brick says 65W. So even at max, I am running about 1.5KWh per day. I pay ~ $0.07 for a KWh so it costs me around 10 cents to run the laptop. At 30Mhash/s minimum, am I still making $$?
Don't forget AC costs for power to cool the constant 65W you are churning-out... The future replacement of that GPU/laptop when the thing fries from "constant operation", which it is not designed for... The internet power and bandwidth you are also paying for... 65W @ 24H @ 28days = 43680WattHoursMonth = 43KWH... AC to cool those BTU's... Roughly 500KWH... Modem-power from bandwidth use... Roughly 15KWH... (About 1/3 of 65W, check the wall-wart for those components. More if it is cable-modem x4 more.) GPU and CPU and HD wear from use/heat/power... Degrades laptops by 5x faster life... up to 20x faster once enough dust collects on the heat-pipes and is not cleaned-off. Still worth it? |

your laptop won't suck more power than a standard light bulb There is no such thing as a "standard" lightbulb... Perhaps your standard is 60W, mine is about 7W (florescent)... or my screen is my light... I have an alien-ware laptop that draws over 300W, peak and 200W nominal. (x-Box does 250W) |
