Is this new?  The website goes to a godaddy parking page.  The Github has has some preliminary data though. It looks interesting, if we can get more information on it's status and timeline.

there is conference on 8th dec in Beijing for launch where you can pick up raw chips & development board. other regions will be added later

for now there is no vacancy for official agents/resellers outside china, so only need to check back on the website for latest news.

chips will be released over time, and slowly gen2 will be on market, with greater hashpower, but to avoid the 51% attack on litecoin network, release is staggered.

We use a multi-generation chip parallel development, and production flow sheet , and all the mining machine and chip spot sales are conducted without pre-sale, so we will choose the right time to release the right products. Our chips will not be counted in order to grab power single-chip index, regardless of the cost, stability, and supply chain speed. We design and make their own production over a number of commercial chips, which you are familiar with the product. We have 15 more years of actual products and engineering experience, from a chip to a cluster, is a systematic project, the need for effective integration from design to supply chain operations. Please wait and see our products and industry chain integration capabilities

Q: Why do not you dig?
A: Of course we have a certain amount of calculation power cluster, however, more people to participate in order to make more healthy the entire ecological chain, we will continue to drive the entire open source project through various activities, each generation will be so.

Q: When will you be officially released and sold?
A: The next weekend we will open a small conference-related information, please visit the official website and www.cybtc.com of Gridchip area:
Gridchip GC3355 chip / mining machine Product Launch
http://www.cybtc.com/forum.php?mod=viewthread&tid=3226&fromuid=2213


While experienced a few months ago notorious Beihong times wild , with the recent upsurge currency, futures and pre-sale everywhere, chips and mining machinery industry is currently true and false news sky fly. Regardless, the mining machine is a high-risk investment, please self-assess their risk tolerance, and saw the loss of cool soaring currency, it is very dangerous.

Recently it was fake Gridseed and Gridchip in online sales on behalf of the mining machine, to remind the miners:
1, Gridseed not yet authorized any company or individual selling any mining machine based GC3355 product.
2, Gridseed's official website is http://www.gridseed.com/ , in addition there is no other website.
3, after the mining machine Gridseed official product sales, will announce sales channels, price, dealer information, etc. on the official website. Not released official online sales channels all fake.
4, Gridseed mining machine products are in stock, after the customer orders 24 hours to pay the full amount, confirmed after payment is received within 3 days of delivery. Sell ​​futures were all fake.

first sale of USB mining machine is four or five chips, depending on the final product of power consumption and heat dissipation.
Citie conducted USB mining machine price quiz, rules are as follows:
1, in this post Reply Guess price elsewhere reply invalid format roughly as follows: 4 chip USB mining machine: XXXX million 5-chip USB mining machine: XXXX yuan
2, each Only a valid ID quiz price, if multiple quiz , follow the results of the first quiz prevail. If the first quiz replies were edited, this ID is invalid
3, after the final price of the product officially announced Guess price and the final price which is closest ID, this ID to get a reward USB mining machines. If there is more than one ID, like the closeness, then who should reply who gets the mining machine
4, quiz End Time: Beijing at 8:00 on December 4, 2013 (ie within 72 hours)

So, it looks real, albeit a little difficult to plan for currently.

specs are here

https://github.com/gridseed/gc3355-doc/blob/master/GC3355_DataSheet.pdf

And holy shit, it claims to do 59.6 KH/s while using 0.44 W

This is 0.00738 W/KH/s versus 0.300 W/KH/s for a GPU -- a 40.7 fold increase in efficiency.  This is about the same increase in efficiency as compared to BTC when ASICMINER first introduced its chips; I'm curious to see how they did it.

Scheduled at 10:00 on December 8, 2013, in West Street, Haidian, Beijing, 70 3W coffee (Haidian Book City, south of the membership across the sea floor), held Gridchip GC3355 chip product launches and mining machines. In addition to the chip and mine-site machine product launches, and BTC, LTC demonstration outside mining, but also on-site sales of 50 sets of single-chip development board and a few chips.

Development board: each 500 yuan
chip: 400 yuan per piece, per pack of 1600 yuan four chips

This price is only preliminary offers developers, not as a formal reference to the product price. Each person can purchase two development boards, chip purchase of two packs per person.

$65 a chip for the early pieces.

It is possible to do scrypt with a fpga, so that implies asic is possible too.  I have seen a POC.  With that said I am extremely skeptical if it can hit above 60k/s rate.  Let alone even 10k/s scrypt hashing rate.

Power efficiency is nice but the number doesn't change that much, you need 10 chips (600$?) to outmatch a 280x (300$?), yes power is the key but this is not "a game changer" just a shift in power consumption, the kh numbers are pretty much the same.

Yep that's a neat feature, doesn't concern the ltc network at all though, ppl react like this will really hit the ltc network hard but in fact, it doesn't change much at all, availability will suck as usual - you need 1,058,750 chips to just double the current diff and bring it up to 4200...

Don't get me wrong, i'll most likely buy some of these since it's really really nice to have but it won't change things as much as most here tend to think.

Yeah but i bet they don't even think about it, its alot of work to put 1 million chips into working devices - why even bother if you can just sell them at much higher instant profit  ;D just sayin, that would only double the current diff, raising the ltc diff to 10k and above is not an easy task xD

My FPGA is hashing at 60Kh/s, granted, it's a 5000$ fpga, but it is possible.

Litecoin will work fine on asic with on-die sram. You can even calculate the hash rate based on known factors.

Code:
200 / (2048 * 8) * Ncores = scrypt hashrate in Mh/s based on 200Mhz clock speed

It appears what they've done to keep the chip small is to implement 4x 256Kbit on-die memories for hashing as I haven't seen anything mentioned about an off chip memory. At 55nm 1mbit of sram is about 7.63mm2. At 28nm 1mbit of sram is 3.88mm2. The max size for QFN-48 (which is a 7x7mm package) silicon is around 4x4mm so have roughly 16mm2 of space. They couldn't have implemented 4x 1mbit as it would be to large (with an exception for the 28nm which would be 15.52mm2, but even then there wouldn't be enough room for all those bitcoin hashers). The speed and stats are certainly within the realm of possibility.

Looks like their site is up. Didn't work the first time.

55nm chip, so definitely within the realm of possibility.

I'm sure someone will reverse engineer (http://www.iacr.org/archive/ches2009/57470361/57470361.pdf) these sooner rather than later, and then we'll be looking at a lot of potential scrypt ASICs hitting the market.  SEMs aren't that costly these days.

That's interesting. If they did implement the SRAM on chip, I guess the could maximally fit 14 scratchpads (14 x 128 KB).  If with 8 they could reach 84 KH/s at let's say a theoretical 0.750 W, we'd max out on a single chip at 147 KH/s and 1.3 W.  Not too shabby if these only cost about $5-10 each to produce on 55 nm QFN-48.

I'd guess they aren't using straight up scratch pads, though, but rather the TMTO desynchronization trick (http://www.openwall.com/lists/crypt-dev/2013/03/21/1) from Solar Designer.  Regardless, the physical limitations as above should still be the same.

On second look, they are using QFN-64 not QFN-48 so they do have some extra wiggle room and may have even been able to do 4x 512Kbit scratchpads.

That's just them being cautious.  If we're familiar with the pinout, it's easier for us to design a board to support it.

I really want to get my hands on a chip to develop.  It's kinda painful how difficult it is to get dev samples of new chips these days.

200 / (2048 * 8) * Ncores = scrypt hashrate in Mh/s based on 200Mhz clock speed

It appears what they've done to keep the chip small is to implement 4x 256Kbit on-die memories for hashing as I haven't seen anything mentioned about an off chip memory. At 55nm 1mbit of sram is about 7.63mm2. At 28nm 1mbit of sram is 3.88mm2. The max size for QFN-48 (which is a 7x7mm package) silicon is around 4x4mm so have roughly 16mm2 of space. They couldn't have implemented 4x 1mbit as it would be to large (with an exception for the 28nm which would be 15.52mm2, but even then there wouldn't be enough room for all those bitcoin hashers). The speed and stats are certainly within the realm of possibility.

Looks like their site is up. Didn't work the first time.

55nm chip, so definitely within the realm of possibility.









Hey senseless, which code are you using for LTC? Thanks a lot

Scrypt requires high speed access to memory so I'm gonna say this is bull until there is some evidence it works.  ;)

its demonstrated already..

I find it interesting the similarities between this chip and the Avalon gen2 chip.
Even the pin outs are similar ???

avalon gen2 is designed by this team

Not too shabby if these only cost about $5-10 each to produce on 55 nm QFN-48.

it's not QFN-48 and cost less than 1$

the price of dev boards and chips so far is not cheap, but not fixed. they will sell at the price people will pay for shovels, supply&demand..next machine contains ~208 chip for total ~12/mhs scrypt and 330g sha256 or 450g sha256 and 8mh/s scrypt depending on mode

Any one know more about this chip?


specs are here

https://github.com/gridseed/gc3355-doc/blob/master/GC3355_DataSheet.pdf

And holy shit, it claims to do 59.6 KH/s while using 0.44 W

This is 0.00738 W/KH/s versus 0.300 W/KH/s for a GPU -- a 40.7 fold increase in efficiency.  This is about the same increase in efficiency as compared to BTC when ASICMINER first introduced its chips; I'm curious to see how they did it.

electricity efficiency is awesome. put me in for 10 units.
the domain is still not ready.

My understanding of that GPU is ~750khs per card. Which runs about 300$. Energy consumption, by massive amount yes. Price will be based on kh per unit. We will be selling @ 0.90$ per khs (Which we have achieved in relation to profitability.) As for kh/s, easily and with only a single unit. Our conservative numbers are 960kh/s with 3.5 watts consumption. I would say we have beaten its numbers pretty thoroughly.

That would be around 75W for the same result with the GC3355 plus some pocketchange in btc

OOPS, I'm a little bit late to this thread.

Hey senseless, which code are you using for LTC? Thanks a lot

Mine probably https://github.com/kramble/FPGA-Litecoin-Miner though senseless should confirm.

The code gets around 16kHash/sec on a LX150 with 4MBit RAM, TMTO LOOKAHEAD_GAP=4 and 16 threads. Or 60kHash/sec on a ztex quad 1.15y board. Its not the most efficient implementation, but its the best I've come up with to date. Someone with a bit more expertise should be able to push this up a bit (it only clocks at around 64MHz and 30% LUT utilization).

Coincidentally the spec quoted for the Gridseed device per LTC unit is pretty much identical to my results, so its certainly possible, though they will probably be clocking it a lot faster and using less RAM overall.

It's likely that ltc price will rise as more people spend more money to mine it, similar to bitcoin. It'll also have more people materially invested in the coins talking about them, also the same result. If Bitcoin price raises to $5k, people will want to get on the next profitable coin. Maybe ltc goes to 250-500.

The picture posted above is an evaluation board or development board for developers, not for end user.

There was a press conference last week in Beijing, where participants can buy those boards and chips.
And those boards are delivered to developers in other part of China this week.

There is no detail information of miners for end user by now. The only info for USB miner is that one USB miner is equipped with 4 or 5 chips, depending on the temperature and cooling design. And USB miner is powered externally with an additional power cable.

That's all the info I know by now. I will let all of you know when new info is published.
I'm Chinese, and I'll do the translator job for all of you don't understand Chinese. Hope my translation is better than Google's. :D

BTW, I brought two development boards and they should be delivered to me in one or two days. I'll post my experience after some testing.

It's likely that ltc price will rise as more people spend more money to mine it, similar to bitcoin. It'll also have more people materially invested in the coins talking about them, also the same result. If Bitcoin price raises to $5k, people will want to get on the next profitable coin. Maybe ltc goes to 250-500.
One would think people can remember that buying ASICs for bitcoins was generally a losing proposition.

At the press conference, the dev board is 500CNY each, and 400CNY for one chip only.
It's ~82USD each dev board, and ~65USD each chip.

You can check chip's datasheet here: https://github.com/gridseed/gc3355-doc and calculate its $/GHash

Personally, I hope the miner's price will be much lower than $65/chip. But there are still many people think the price will remain the same.

There is no detail information of miners for end user by now. The only info for USB miner is that one USB miner is equipped with 4 or 5 chips, depending on the temperature and cooling design. And USB miner is powered externally with an additional power cable.

That's all the info I know by now. I will let all of you know when new info is published.
I'm Chinese, and I'll do the translator job for all of you don't understand Chinese. Hope my translation is better than Google's. :D

BTW, I brought two development boards and they should be delivered to me in one or two days. I'll post my experience after some testing.
Super!

Can you share with us what was the cost of dev boards?

Thank you

At the press conference, the dev board is 500CNY each, and 400CNY for one chip only.
It's ~82USD each dev board, and ~65USD each chip.

You can check chip's datasheet here: https://github.com/gridseed/gc3355-doc and calculate its $/GHash

Personally, I hope the miner's price will be much lower than $65/chip. But there are still many people think the price will remain the same.
Thank you

Unfortunately 65 USD/chip for mass production is not a deal for me. Let us hope that they will lower the price when time comes.
Best

Do you think you could ask them if they're using 512Kbit or 256Kbit of memory per core? I'm curious if they're using "lookup gap" 2 or 3.

Very cool stuff.

Definitely interested in LTC and BTC as well.

Hybrid approach is very creative.


It would be, if it was produced one year ago. They missed BTC train, and additional scrypt power will not be enough to catch up. I would bet on solo scrypt ASIC, not on hybrid...

The chips only cost a few dollars each to produce, so there's a big margin for profit there...  It'll come down to be competitive, same as before with ASICMINER.

Shure they will do, but they will become of no interest for us even if they are free, because just money and time spent to make them mine will never pay out. I am not talking about profit at all

Pilot is 1.2TH Scrypt mining lab. Maybe 50000 of these chips with 1/40 of the GPU powertake.
This Scrypt Hashpower would translate to around what 2000 AMD GPU cards.. with powertake +300kwh..
Just rough numbers i could assume wrong. but hey i would wanna see that 2000 GPU farm  ;D

Ah ok. For some reason I thought that USB device only had one chip.

At the press conference, the dev board is 500CNY each, and 400CNY for one chip only.
It's ~82USD each dev board, and ~65USD each chip.

You can check chip's datasheet here: https://github.com/gridseed/gc3355-doc and calculate its $/GHash

So that little 360Kh/s miner costs $82 + 6x$65 + HSF? You're talking almost $500! Unless you pay like $0.30/kWh, you're better off with GPUs. What will the final cost be, does anyone know?

They are totally out of the ball park if they think $60+ a chip will work

Really need to be ~ $30 for it to come close ...I have ~ 55% of my rigs already on solar so until they get at least within GPU ball park numbers they are a non starter and just a curio for noobs

2) Within the group buy of 10 pple they can max purchase only 400 or 40 chips per person or is that 40 360k miners per person ?
3) Is the delivery date May 2014 ??
4) Only way to contact is via QQ ??

AND They are not keen selling them. With prices ppl suggest here. If you have Machine laying golden eggs while none else have why would you sell it. Also this is totally GEN 1 hardware and totally in line what first SHA Bitcoin ASIC:s were performing. The Chip is not super performer but what it does it does it 1/40th of the Electricity of GPU rig

PPL are blinded by current GH and TH of BTC ASIC. If and when they get mass sampling of this chip what would stop them putting 160 chips in a Blade taking 70-100W and producing massive 9.6MH/s thats 12 GPU rig right there in 1 single ~70W blade.

Price? dont dream about it. They will mine and overprice the chip to cover R&D costs and get healty profit before dumping them into the market. If you are first you are First.


-Edit-

http://www.middlecoin.com/reports/1M3jtksp1upR33SX1VzeCfH5x9fc6zKykR.html

Been following above middlecoin address and they have add around 100MH/s daily there. Thursday - Friday - Monday - Tuesday - Today i just saw 957MH/s accepted. It is past 1GH/s accepted hashrate tomorrow evening. That would be closer 2000 AMD GPU units in mining rigs and rough numbers would be what 500-700 kw/h power and heat at minimum. I'm no professional but i would say it's not easy to obtain that much power. Compared these chips would do it with 7-15kw/h which is nothing.

specs are here

https://github.com/gridseed/gc3355-doc/blob/master/GC3355_DataSheet.pdf

And holy shit, it claims to do 59.6 KH/s while using 0.44 W

This is 0.00738 W/KH/s versus 0.300 W/KH/s for a GPU -- a 40.7 fold increase in efficiency.  This is about the same increase in efficiency as compared to BTC when ASICMINER first introduced its chips; I'm curious to see how they did it.

Anyone still thinking about getting into GPU mining better give up now. This is going to go down exactly the same way bitcoin did. GPUs will be dead soon.
That would imply Litecoin valuation at many Billions all within a few months?  GPUs left bitcoin for litecoin.  Where will the they go after?

AND They are not keen selling them. With prices ppl suggest here. If you have Machine laying golden eggs while none else have why would you sell it. Also this is totally GEN 1 hardware and totally in line what first SHA Bitcoin ASIC:s were performing. The Chip is not super performer but what it does it does it 1/40th of the Electricity of GPU rig

PPL are blinded by current GH and TH of BTC ASIC. If and when they get mass sampling of this chip what would stop them putting 160 chips in a Blade taking 70-100W and producing massive 9.6MH/s thats 12 GPU rig right there in 1 single ~70W blade.

Price? dont dream about it. They will mine and overprice the chip to cover R&D costs and get healty profit before dumping them into the market. If you are first you are First.


-Edit-

http://www.middlecoin.com/reports/1M3jtksp1upR33SX1VzeCfH5x9fc6zKykR.html

Been following above middlecoin address and they have add around 100MH/s daily there. Thursday - Friday - Monday - Tuesday - Today i just saw 957MH/s accepted. It is past 1GH/s accepted hashrate tomorrow evening. That would be closer 2000 AMD GPU units in mining rigs and rough numbers would be what 500-700 kw/h power and heat at minimum. I'm no professional but i would say it's not easy to obtain that much power. Compared these chips would do it with 7-15kw/h which is nothing.

specs are here

https://github.com/gridseed/gc3355-doc/blob/master/GC3355_DataSheet.pdf

And holy shit, it claims to do 59.6 KH/s while using 0.44 W

This is 0.00738 W/KH/s versus 0.300 W/KH/s for a GPU -- a 40.7 fold increase in efficiency.  This is about the same increase in efficiency as compared to BTC when ASICMINER first introduced its chips; I'm curious to see how they did it.


I've seen that on Middlecoin, but I'm failing to see how this is transformational.  It would seem to me that the key in the near term (at least months) is equipment price/kh, not kh/kw.  Granted, I have cheap power in the US, but at the rates alt coins are paying, the cost of power is almost exactly an entire order of magnitude less than the revenue that can be obtained by that power.  Case in point: 0.01 BTC/day/(MH/s) is pretty easy to reliably obtain.  For 1Mh/s, you're looking at about 300-350 W.  0.01 BTC = about $8.5 currently (and stands to rise).  350W = $1.68 even at a very liberal $0.20/KWhr. 

My point with all of this is that hashing power is clearly the dominant metric for profit at this point.  With that said, the prices listed in this thread for ASIC hardware are about two-fold WORSE than typical cost/hash represented through GPU mining.

What this is all leading me to is this - if power could (even liberally) be assumed to be soaking a quarter of your revenue from GPU mining, and these products are twice the cost of GPU mining, there is literally NO break-even.  Even if they use no power at all, the best you could do with them is still to bring two thirds of the profit/investment of GPU mining.

It seems that these become a true alternative when they get to between the 1.0x and maybe 1.25x the price/hash power, and truly preferable when cheaper still.  Similarly, it would take until profits/hash power are halved from their current levels to have the same effect.  With all of the pump and dump coins and stupid speculators betting on them in the short term coming and going, I don't see that happening any time soon.

Am I wrong?

I'll be honest; I just want to play with a couple of the chips.  As an engineer, it's fun to play with new technology, and as has been mentioned... 1st gen is 1st gen.  This may not be up to par with BTC yet, or even GPU mining, but it's progress and it's exciting.  The 2nd gen will be even more fun.

If anyone has access to these chips and is willing to work something out with me re: purchase and shipping to the US, send me a PM.  Good work Gridseed.

+1

You are exactly right. These wont be obtainable within eaven close to get break-eaven in investment. Power usage wont matter that much in >10MH scale. They are just too rare when they hit the market. Gridseed can easily charge 1000% margins for them and people will still buy like crazy. When will they hit the market. Not in months. Takes alot time before they show any significat Hashing power in current Scrypt world.

That said i would say there is easy 6 months left for Healty GPU mining. These wont kill it. Yet.

GPU still best way to earn $

ps. Cheshyr i'm on a same boat i wish to see the technology. I could buy 1 of these just to see it in action.

Guys, i'm italian.
here, to build a gpu mining rig, whit 5 r9 280x for a 3.6 Mh/s, you pay about 2000 euro.
estimated consumption even undervolting cards, is about 1.4 Kw/h that costs about 5.00 euro/day
the Gridseed ASIC, if i right understand, have 5 chips even "usb device" and it can do about 300 Khash/s for a consumption of about 30V. so, 10 device that i read cost 1360$ (1000 euro) would get 3,0 Mhash/s for about 300V. power costs is about 1.10 euro/day

ASIC miner 1euro = 3 Khash/s + 1.10 euro power/day
GPU miner 1 euro =1.8 Khash/s + 5.00 euro power/day

assuming that 1Mh made 0.01 BTC day:
asic miner made 0.03 BTC/day that is 25.5$ (18.75 euro) - power (1.10 euro) total 17.65 euro/day net (time to autopay 57 days)
GPU miner made 0.036 BTC/day that is 30.6$ (22.50 euro) - power (5.00 euro) total 17.50 euro/day net (time to autopay 114 days)
not counting space problems, overheating, noise etc.

in Italy, Gridseed ASIC is much more profittable than any GPU for scrypt mining now.

This is the (unfortunate) misconception that came about with poor translation and horrible press from Gridseed.  The cost for a single USB machine (which includes 6x 60kh/s units) is $82 + 6 x $65 = $472.  So you're paying $472 for 360kh/s.  The minimum order is 10 of *these*, not 10 single chips (unless I'm mistaken), making the total for 3.6MH/s of hashing power $4720.

Indeed, and it's 5 chips on each miner operating at between 300-360 total (not each).

As for power, it appears to be .44W per chip in LTC mode and 5.3W per chip in hybrid mode

Here is where the chip prices were first confirmed at about $65:
http://www.cybtc.com/thread-3226-1-1.html
Quote
Development board: each 500 yuan
chip: 400 yuan per piece, per pack of 1600 yuan four chips
This price is only preliminary offers developers, not as a formal reference to the product price. Each person can purchase two development boards, chip purchase of two packs per person.

And here is a link to the specs sheet of the chips
https://docs.google.com/file/d/0BxFU17PfhOeeaEVlM3Q1VDBlUkU/edit

I'm interested to see what happens with these.

Thanks for the translation

I think it is a avalon repeat lets mine for ourselfs deal....

$4720 for 3.6m is a total fucking joke its at least 300% more expensive than a gpu rig ..in a way this is good that they have priced it out of reach of anybody who is serious with mining

Also what is it with these pplz that they basically put something up for sale with basically NO real potential profit for anybody

ASICMINER
AVALON batch 3

Realistically just self mine and stop trapping suckers... @ 12c kw it will take 3 years to recoup the extra cost of ~ 3k extra compared to a GPU rig

Thats legit !

my automatic translator for this site: http://www.cybtc.com/forum.php?mod=viewthread&tid=4792&highlight=gc3355
say that: Chip: Gridseed GC3355 X 5, so i think every device, has 5 chips inside.
there's a lot of pics in this chinese forum, and my traslatror sayd that first 400 devices are sold in paket of 10 devices to 3 groups of people of that forum, who, substancially, should be testing this beta device.

there aren any price.

only in an other forum a guy talk about price of 8200 rmb. thats the font:
http://www.reddit.com/r/litecoinmining/comments/1vbj65/gridseed_releases_script_asic_capable_of_36_mhs/

so i think gridseed has developed his device using gc3355, and now they sold a 1st beta batch of 400 pieces for tests it whit ristrect numbers of chinese miners. sold a limited beta device for tests it, is a great idea for firm :)

thats only my opinion obv.

you are in the right, Andr3wKay.
and dont forget VAT.
i reckon that Alpha-T 5Mhs device in italy will costs about 2100 euro including tax and shipping.
2 rigs whit 7 R9 280x for same hashrate, will costs about 3000 euro.

great difference in power consumption. 100w for alpha-t device, 2000w for rigs....

actually alpha-t device is the best choice without dobt.
but we dont know for sure if it is a scam or if it real and legal, and, if real, when they start to delivery on large scale.

really, i'm looking to build a 5gpu mining rig, but now i have a lot of dubt.

You pay 60$ a chip, they pay 1$.  They will push as many GH/sec as they can as fast as they can and mine themselves.  For them, these chips pay themselves back measured in hours.

If anyone is dumb enough to buy their chips, they will put out several dozen for every one you buy, funded entirely by you.

Scrypt is dead.
Scrypt on GPUs is only dead when the hashrate on network surpasses by a long shot the # and valuation of shitcoins generated, marketed and entering exchanges every single day.

I've been mining memorycoin which isn't scrypt for a few days though. In the best days, I got 3x the profit and the GPUs use ~60W each instead of 150

You pay 60$ a chip, they pay 1$.  They will push as many GH/sec as they can as fast as they can and mine themselves.  For them, these chips pay themselves back measured in hours.

If anyone is dumb enough to buy their chips, they will put out several dozen for every one you buy, funded entirely by you.

Scrypt is dead.

+1 i like your ideas
+2 for facts
+3 in a gold rush those who will sell parts will gain most capital. IF this company is legit and can do it, Scrypt mining. Only means there will be +10 more in next 6 months.

Scrypt for GPUs is not dead at this very date and for all gamers out there soon will be good stock of AMD GPUs that can handle all proper games nicely. Very cheap. All this fuzz and valuation of silly altcoins will keep up the GPU mining proftability for those people who want to invest time and focus on it. As power and watts per KH/s GPU mining is dead and ecological disaster. Dedicated chips will do the same Scrypt job with 1/40, then 1/100 and then 1/1000 of the Power cost of a GFX Card.

Also this chip will only currently do Litecoins. +6months there will be least dozen more companys with their chip solutions.

As a GPU miner which i am not. i would seriously evaluate ROI point and resale value to get ride of GPU mining and investing same capital to BTC or something else. Waiting for next wave of hardware mining. Early adopters always gain the benefits. The people who are planning to make 8, 12, 16 GPU rigs now... dont, you are too late. Goldrush is gone.

when is the next batch of these expected to be sold? and/or waiting list or whatever I may have to do to hear about such?

not sure i'll do so..but on the short list for the alpha scrpyt machine 5mh at 2200 bucks or so (I'm brave have 45 day protection paypal)

10 of these gridseed units look like a better deal and guicker out the door then july for the above alpha units  (again I'm fence sitting on all this just saying)

anyhoo a link to where to watch or get in line or whatever so I can keep track

their site simply says "coming soon"

Bad advice. GPU mining will allways be more fun and risk free than entering ASIC spiral that streams all the coins to ASIC sources. If scrypt coins developers want, they can make changes towards different algo. GPUs will adapt, what will happen to scryptASICS? They will continue diving into BTC ASIC spiral. That's why nobody is producing scrypt-only ASIC.

US $4,369.00
Power: 60W for one , 600W for 10pcs

So you get 10x 80GH/s SHA and 10x 3MH/s scrypt for $4,369.00 or how is this listing to be understood?

The value of both btc and ltc must nearly triple if that 80g-/3mhs contraption will have any chance making the return of investment at the price of 4300 buckaroos...
Only reason you would buy this is if you're pretty darn sure that this will happen and hanging on to the mined coins until it eventually does.

now the sell  only in china,one USB miner include 5 Gridseed GC3355 chips,about $133

BTC rate:10G/S
LTC rate:300K/S

power of  BTC+LTC Mode:60W
power of LTC Mode:7W

and many coinminers have 360K/S in LTC Mode

2700$ for 20 devices for 6Mhs in LTC mode only, is about 30% cheaper than equal hashrate GPU mining rig
but the great saving is power.

6Mhs gpu rig use about 2100w at the wall
6Mhs asic only L mode use about 140w + 100w? (my own valutation) for alimentation of various usb strips....

8.75 times less power!!!!

coinwarz: mhs 6000 power 2100 LTC net revenue 30.15$ (italian power cost applied)
coinwarz: mhs 6000 power 250 LTC net revenue 39.11$ (italian power cost applied)
it's 29.72% more profitable

definitely we got 30% more profit whit 30% less investiment.

so i'm sad... i just ordered my 5 gpu...

Don't be sad, gpu's have great resale-value :) - both miners and gamers are still in love with those nifty little chips from amd.
But I think the price is about right for that scrypt-asic miner and if they are able to provide the scene with a steady supply we'll see an even more rapid increase in difficulty and thus rendering our nice little gpu-rigs utter useless for scrypt-mining soon. Sigh.
Unless you've got some crazy deal with free power and cheap gpu's (got free power myself tho. )

So total per month for each one in $/kWh is

$350.00-USD 1x 280x 720kh/sec 0.09$/kWh 24/7 x 30 days = $16.20-USD
$1200.00-USD 12x usb miners 720kh/sec 0.09$/kWh 24/7 x 30 days = $1.50-USD

You would save $14.70 per month on your electricity bill, however you spent 650.00 more for the USB miners. It would take you 44+ months to make up for the cost.
So is it worth it? Not with AMD pumping out 20mn chips soon.

Also quick resell value of the 280x, around 300.  USB chips that only do two things? Not worried about ASIC for scrypt at all.

GPU-mining still have several months of profitable mining even with the diff going up.
And as long as you can sell your gpu's when you feel they have outlived their purpose you will have good chances of getting your return of the investment and a profit out of it in the end.

It's win win.  If LTC follows BTC price pattern when ASICs come out then any coins you mine now with GPUs will be worth 10 times more.  If it doesn't then without the big price increase ASICs will not be worth buying and will either not be a factor or force the manufacturers to sell them cheap.

Difficult skyrockets all miners loose out except them  ..
 
------


People are fixating on the fact that the power consumption of these things is low and how much more they can "possibly" make mining and they are missing the whole picture! You are getting fleeced!

You buy 1 and they make 10 for them and they jump on the network and take your "possible" earnings too.

Its like paying up front to get hit in the head with a baseball bat and then you are letting them come back every day thereafter and arse rape you again by taking your future profits by mining themselves! They are whats looking like a botnet on mc! They are already gaining 100MH's / day!

Dam are people that stupid or what!

Greedseed pfft..

Then you understand why people who sell vaccines shouldnt be spreading variants of whatever they were supposed to protect you from. That would be just lining their pockets and making it really bad for everyone else but you knew that.

That's correct, they are not interested in us sales at this time. A limited number of those miners were made, less than 100 batches of ten, and sold first come first serve via a qq chat. I had someone trying to get them for me in china, but by the time they told me the orders opened and I said yes, they sold out.

As soon as they are making them in large amounts, which can't happen until at least after Chinese New Year, we won't see any of them.

66 bucks for a chip produced in batch processing in 56nm ... that are some thousend chip/wafer ...  I understand the development cost are vary high , buts 66$ is too much .  

This reaches the price range of CPU/GPU Chips , which are much more complex then these chips.

But if one stick costs 100$ and profit is 1$ a day (70Kh/s)  then you will never reach the break even, I think... 100 days are a very long time in crypto.

If this is the beginning of the asic race, these sticks will be worthless in 100 days.

ok thank you guess I'm stuck for now have a www.alpha-t.net on order and have a couple weeks under paypal to decide if I wish to get this or not they are likely legit but don't seem to have much of a clue yet and state july delivery for 5mh at I think it was around 2200usd (only asked 1/3 down and I can bail with paypal and cc ...again likely legit but july is a long way away)

would xfer usd to btc in the states here and pay for it btc rather have 10 units now at 2600 bucks..but alas seems to complicated to do now and they don't seem to want to sell to the English speaking world or at least not yet

Can I ask why you would pay 2600 in btc for these device? first of all is a huge markup, and the units will not see a positive return.

I knew there would be many suckers queue up to buy this but really underestimated, otherwise would of collected much bigger qty

well it was 1/3 down via paypal ....was 100w and no....I probably very likely will bail on it....have 45 days with paypal and paid amex credit card the 1/3 down and amex says I have 90 days on a pre-order ...someone says master card is 120 days ..in other words if you file a claim you have not gotten it (pre-order) you can sit in line an see how it goes...they claim www.alpha-t.net that they will refund full for 30 days after that they will take I think it was 15%...the amex lady just laughed...if you don't get something in 90 days you get your $$$ back if you file a dispute..they can't do that (call amex mastercard or whomever yourself )

anyway will likely punt in another week or so.....have been doing more research (thus you guys) and July is too long to wait (a noob on litecoin)
nothing wrong with sitting in line with paypal and a credit card if you have an exit strategy...did so with www.kncminer.com and got comfortable enough to keep that paypal amex pre-order (thank god oct Jupiter 555gh 7,131.80 usd to usa....today I will hit my 40th coin on slush started mining with it 0ct 18th ordered it july 1st.)

so again nothing wrong with this game as long as they take paypal (use cc option in paypal) or credit card.....always have a way out

yeah I'm gonna punt......like I said they are likely legit prototype fpga etc..but they look like me and my buddy with a 'connection' with a chip mnfg in India trying to make something remotely.......intentions are good I think but they probably won't get the thing out till Fall imho

anyway still learning about litecoin stuff (sure can't get any bitcoin asic miners in the next 2 months at least imho at least from kncminer)

anyway......that is my somewhat warped logic (at this point in BTC you probably should just buy BTC and skip mining getting awful scary....maybe this even works better for LTC too!)

my somewhat odd logic on the above

Guys,
I am trying to keep an eye to all the project based on the gridseed chips and the distributors and/or resellers...
Litecoin forum: https://litecointalk.org/index.php?topic=6506.0
I believe cybtc.com is a reseller of the round 5-chip miners:
http://cybtc.com/it618_scoremall-scoremall_page.html?pid=36
11198 元 ?? = 1 368 Euro is that correct? could someone tell me if this is the price for 1 unit or 10? or 20? I really struggle with the chinese...

LightningASIC is shipping to the USA.  10 units plus accessories for $2600 + $150 shipping.

I've seen this price in one of the posts on the litecointalk.org forums, but I don't know if it was actually confirmed by the seller asiabtc who started that thread.  Did we ever get confirmation from asiabtc that he'll honour this price or was this just more speculation in the thread (or wishful thinking)?

That is the price I got from AsiaBTC via private messages with him.

Mattzees, did asiabtc also mention what's included in the price? I've been trying to get that squared away on the litecointalk thread, but no one seems to know...its it just the miners+cables+controller board? 

It was 10x miners, the controller, all cables and power supplies, a USB hub, and other misc accessories. 
I'm not buying it, just FYI.

Thanks for the info..I didn't know PSU was included so that's nice.  I'm considering it the only reservation I have now is the quality of the product...its got no track record or decent warranty period...my fear is dropping $2600 only have have one or more of the modules crap out...at least with a GPU I've got MSI's warranty to back it up.  Tough decision...I need to cut my monthly power bill and also reduce the heat by the time spring comes around...

I have the same issues as you with electric bill and heat.  Right now, I'm heating my house with my rigs.  It's been below 20F outside, my heat is turned off, and it's above 70F inside.  This is obviously not going to work during the summer.  I already have to open windows if the outside temps goes above 40F.

That being said... I don't think these units are the answer to the problem.  The controller is proprietary and a centralized point of failure.  I'm not at all interested in BTC mining with these (because it's pointless), so I'm going to hold out for a more efficient scrypt ASIC product.  

Even Gridseed says they're going to be releasing new product in Feb., and seem to indicate it wil be rack-mounted, which is a better option for me.

Beastlymac -- Yeah 30 days doesn't give me a lot of confidence.  With my luck all 10 of the units would crap out on day 31. :P  Not meant to be negative towards the product manufacture, but more so a reflection of my actual luck with mining parts.

Mattzees -- Yep, following that thread as well as this one.  Yeah as much as I would love to get in on this, the more and more I reflect on it, the more I think its better to wait till mid/late Feb to see what happens then.  Gridseed may have something new out...that and (fingers crossed) there's also projects out there by Fibbonacci and Flower which in theory will kick-off Q2 which could be comparable...Ultimately my goal is to identify a strategy I feel comfortable with so I come May time frame I'll be off my hot GPU rig and onto ASIC/FPGA solutions instead for the same 3MH.

Yeah, I've been thinking about your GB quite a bit...but at .405BTC * 10 = 4.05BTC * ~$800USD = $3240...it puts the offer way out of my budget. :-[  This in context to asiabtc's $2600USD means there's quite a premium for the devices and the additional 3 months of warranty you provide.  Sorry mate, but I've only got $2500 or so budgeted for the "change" from GPU to ASIC/FPGA....so I'll probably sit this round out.  I do very much appreciate the service you provide to this community...if it wasn't for folks like you doing Group Buys, I wouldn't even have a chance to consider such opportunities.  :)

I apologize in advance if I sound needlessly argumentative...but by that logic, the extra $640 is the "premium" being charged to guarantee we get the units ordered and they're not DOA?  I don't believe this group buy has made any statements at all related to dealing with DOAs or non-delivery. 

I guess it's my limited budget that has me thinking $640 is too much of a premium to fork out.  I 100% sincerely wish this group buy the best possible outcome...I hope that perhaps in the next group buy the prices will be a bit more in line with what I can afford (and what I believe these devices are actually worth considering the non-existant track record of the manufacture, resellers, etc.)  I guess this goes is in alignment with my limited ability absorb financial risk as we purchasers are taking a large risk in buying these units, with only a minimal 30 day warranty...with only "good will" to ensure this all turns out right,  units are supplied in a timely manner, not DOA, etc. is just too much for me.   :'(

Since someone mentioned Jack Liam AKA asianbtc AKA lightningasic, I'll post my convo with him as it seems the price fluctuates quite a bit.

Jack:" i have USB cell. 300KHS, LA3M, 3MHS, LA6M 6MHS scrypt."
Price is "LA6M, usd5100+usd300 for express" <-----------------------------------------------------which means 6mh/s of gridseed units

This next quoted thing doesn't make much sense as it says "4 PCS", which could mean 4 of the LA3M............ each being 3MH/s of gridseeds.
Jack: "4 PCS LA3M. usd2750 including dhl express"

From my understand LA3M=10 gridseed units in a "cell" and LA6M is 20 gridseeds in a cell. He says all power supplies, cables, etc. are included.

I think the last quote is either in error or is a dam good deal. 4x LA3M cells, 40 gridseeds in total, for 2750usd($68.75 for each 5 chip gridseed)..........but 1x LA6M which is 20 gridseeds would be $5100........so something ain't right.

I have a friend in China that can get them for me, so I didn't ask Jack to clarify on the LA3M thing. I just let it drop since $5100 for an LA6M is far higher than advertised anywhere else, making Jack a bit shady to me. Well at least extremely greedy, if not outright shady.

Don't shoot the messenger, I'm just passing on info I have :)

If you have a old PC power supply laying around you could probably us it for power.

Looks like he's using yellow (12volt).

Yellow is 12 volt,red is 5 volt & black is ground:

Yes I have spoke with him as well and this is the price. Yes it doesnt make any sense and i tried to explain that to him but he said they sell so he doesnt care.

Edit after redoing some numbers it actully does make sense.

the la6m is 5100 + 300 for shipping = 5400
2 la3m is 2600x2 + 150x2 for shipping = 5500

Jack: "4 PCS LA3M. usd2750 including dhl express"

From my understand LA3M=10 gridseed units in a "cell" and LA6M is 20 gridseeds in a cell. He says all power supplies, cables, etc. are included.

I think the last quote is either in error or is a dam good deal. 4x LA3M cells, 40 gridseeds in total, for 2750usd($68.75 for each 5 chip gridseed)..........but 1x LA6M which is 20 gridseeds would be $5100........so something ain't right.

I have a friend in China that can get them for me, so I didn't ask Jack to clarify on the LA3M thing. I just let it drop since $5100 for an LA6M is far higher than advertised anywhere else, making Jack a bit shady to me. Well at least extremely greedy, if not outright shady.

Don't shoot the messenger, I'm just passing on info I have :)

Yes I have spoke with him as well and this is the price. Yes it doesnt make any sense and i tried to explain that to him but he said they sell so he doesnt care.

Edit after redoing some numbers it actully does make sense.

the la6m is 5100 + 300 for shipping = 5400
2 la3m is 2600x2 + 150x2 for shipping = 5500

Hey Star,

Did you end up ordering from him? I know of one person who has ordered from him so far with no issues. (He has quote me 2750 all in for LA3M--worth it??)

FYI, I paid 3.44BTC which was $2750USD about 2 weeks ago.  Haven't got them yet, but assuming they work as advertised I think it will be worth it.

Hello, i am from china mainland and knew something about gridchip.

I saw a lot of people bought the dualminer from the lightingasic.com, but I checked the official website and was unable to get that website in the approved seller list.

see this link (http://bbs.diginforce.com/forum.php?mod=viewthread&tid=18&extra=page%3D1) about the introduction of gridseed an the only legal seller. Please take care of that website (it seems that they rebrand gripchip set as lm6a/lm10a).

I think it would be something to consider as part of a diversified approach to cryptos....at this time, I'm tapped out of coinage...so perhaps in the future, I've got it bookmarked!

Also, I think part of the fun of cryptos is the actual mining.  Setting up my GPU-based rig, getting it stable, optimized, etc. was truckloads of fun and a great way to learn...so I'm not just in this entirely to make $$$$$ but also participate in the community as well....

People have received what they have ordered from lightingasic.com, so what´s the problem? I don't know this situation exactly, but in China lot of companies sell products from different factories and only few are "authorized", most are "agents". I have done years of business with chinese companies and generally no problems at all.

Here is the only place supported by gridchip development team:
http://cybtc.com/forum-83-1.html

Here is the latest announcement from gridchip dev team:
http://cybtc.com/thread-5952-1-1.html

This chip is only owned and produced by gridchip and there is no different factories to make different dualminer. If lightingasic.com is not the valid reseller, which means that it got the dualminers from public selling channel and no direct technical support and warranty. You got the problem from miner and you had to send them to lightingasic and then lightingasic sent them to official company. Lighting has no the stable source of good, which means the ship date will also be impacted.

BTW: cybtc.com is the valid reseller and approved by official. It has 5 dualminer sets quota each day since now. LOL. You can count the result by the selling date(last column of this link: http://cybtc.com/it618_scoremall-scoremall_page.html?pid=36)

I dont really care if some company is official reseller or not. I just want good price and fine delivery.
If one unit fails, who cares to send back. Maybe a bit different if whole set fails, but I dont think so.
Buy from where you want. However sometimes small sellers are able to offer faster delivery and even better customer service than
big companies. Just my two coins.

What is the easiest method of powering the 5-chip model?

I received a 12v 5a power brick that as easy as it gets for powering each gridseed. It is not as efficient as a PSU but it is a clean setup.

Hi,

Can you plug the gridseed to the usb port of a computer without the 12v adaptor?

Beastlymac (or anyone who has these in hand), can you tell me if the unit is only being run in Scrypt mode does it still need the power adapter or can it run entirely off the USB connector?

No. Each chip is equivalent to one of the USB dual miners. Each dual miner sucks up all the power of a USB 2.0 port. Each unit has 5 chips, so you would need 5x power of a USB 2.0 port (maybe 4x since you don't have to multiply the support stuff).

Quote
I've got a bizarre idea on how to mount these using 4" PVC tubing that i'll cut a slit down the side of for cable and reset access.  Each tube will be a stack of miners working in their own little wind tunnel.  I may even remove the fans from the individual units and just mount a single inlet/exhaust fan at each end since i've heard they generate very little heat. 

That could work.

Nope, it receives the work but does nothing with it. Maybe if you have some juiced up HUB you could try it but not on a normal powered HUB or directly plugged into the PC. It screws up the COM ports doing this and you have to restart your PC  :-\.

Guy could someone work out an average ROI on one of these sets. $2700 for 3000 hash power. It seems to work out 120-240 days before roi is reached. Or am I missing something? with more and more of these units being sold( a huge amount) isn't this also going to up the difficulty in the coming months? does this mean that coin wars calculator for coin profit isn't accurate because it doesn't take into account difficulty increases in coins?

If hypothetically you were to mine 3000/ms on middle coin for 4 months, would you even see roo in 4 months? Also these units are new so if they fail after 2-3 months(which no one knows it true or not, isn't this a null void waste. I understand there is risk, but it seems a bit troubling to say the least when you do the math from say March onwards..?

So you think when these more sophisticated algos pop up... GPUs will be able to switch over more easily before asics catch up? I still think GPUs are the best option for scrypt (price/kh, re sale value, etc), but even better if they can hop over to a new algo in the near future.

So far on these the best price I have seen on the gridseed is Zoomhash.com at least in the us. I have ordered one to see how they work  and test them out. Theres a site in China and I believe it is the distributer selling them for 150 USD but you have to order a large amount 50+ I think was the number.

Anyone setup a LA3M system using the Version B Control Board (the red one)?  I think mine was dead on arrival but in case for some reason I just don't understand plugging things in I wanted to see if I wasn't the only one with a dead unit.  Plug in on the separate 5V connector, Ethernet, MicroSD in, etc. no lights or any signs of coming online.  I don't know what they would use for the JTAG connector so I cannot bring it up with my Xilinx USB Adapter to see if it can boot that way.

I have Gridseed miners in my possession let me know if anyone is interested. My partner lives in China by the factory. I have been importing and exporting for 14 years now.  I am located in the Ann Arbor Michigan area we have daily flights to and from China for all products.

According to this review (http://cryptomining-blog.com/1158-first-impressions-from-the-gridseed-5-chip-scrypt-asic/), the 5-chip Gridseed Miner pulls almost 60W mining Litecoin and only does around 350KH/s...

Is there something I am missing?  Why are people spending $300 on this ASIC, when a ($110-150) Radeon 7850 has equivalent specs and about the same hashrate (ie 350-380 KH/s)??

Gridseed is doing 300 khs at 50-60 watts these days. They claimed 10 watts, but none of the reviews show that low power use.

Even a $200 ($230 now) R9-270 will do 450khs at 150 watts. Hardly 10-20x the power.

Ok then.

All of my photos and readings for power are in the thread.  You sir are lying.

at 300-350Khs per device on the controller, on windows and on linux I have verified by several users 6-10Watts per device.

Show me a review that shows more power for single scrypt mode?

So what you meant to say is if you buy 10 and have the correct controller setup, you can get it to run in low power mode. Where can you do that if you only run one? 

I really don't give a shit about it, and don't want to waste time arguing with you since you are just trying to sell something.

Still, power is cheap, and the gridseed stuff is overpriced. It would take a long time to make up the difference in power usage vs initial cost.

Here is a link that shows you how to run in scrypt only mode which is what many are doing to achieve lower power consumption of 8watts per unit. If you run in dual mode or sha256 mode you will use the 60watts.
As shown here you do not need a controller, can simply hook the unit up to an existing PC. Power may be cheap depending on where you live, it is a wide range really.  For me power cost doubles in the summer months where I would not want to run a GPU farm as it eats into more profits trying to power it and keep it cool versus a device like this. Speaking from experience, sold the GPU farm to run year round with devices like this.

I think the benefit from a gridseed miner is that you can let it run, without the need of having a motherboard, a psu, ram, cpu, case ... what ever you need to host 4 or 6 of your R9-270, also not to mention that the gpus will get much hotter then those little miners ...

I can't speak for others but I bought these because they don't heat up my place.  I've got a GPU rig which sucks 1200watts out of the wall and has been a good "heater" for my small apt.  Unfortunately power is not cheap where I live so I thought the trade off of higher price for gridseeds was worth the:

1. Reduced power consumption
2. Reduced heat (especially in the crazy hot/humid spring/summer)
3. Reduced noise (once I gut the fans off since I'm scrypt only mining)

Each person makes up their own minds on what's right for them.  Honestly I thought I'd toss out my GPU rig once I got my gridseeds, but after the instability of the controller and a burned out cheap PSU, I figured my GPU rig is sort of a fallback/insurance strategy...so I decided to keep it around a little longer.  I was hoping to sell it off for about $1500 which I would count against the cost of my gridseeds...my GPU rig has already paid itself off and the proceeds from it allowed me to afford buying the gridseed miners...so all in all not bad and worth it in my opinion.

Just checked, my 10 Gridseed units running at about 3500 khs total in scrypt only mode doing 70 watt on the wall. It's less than 7 watt per 300 khs.

10 Gridseed miners running between 3300-3500khs (varies due to the switching pool I'm using) pulling 100watts (thats 10 miners, 1 usb hub, 1 RasPi, and 2 PSUs) in total.  I've also got the frequency set to 850, so I'm sure that pulls extra watts vs the 7watts/300khs on default 600.

I would appreciate some clear guidance on this as I'm looking for a way to run 1 or a few in future independently from a computer,while still being able to manage and change settings remotely.

I am in your postition somewhat as I own two of these and run them on a pc.  In fact I can only get one to run on the pc not both.

In my case I have 5 pc's running gpus to mine various coins along with the gridseeds and  some btc usb sticks.

I have 4 more gridseeds on order. this will bring me to 6 gridseeds 5 pc's 8 gpu's.  I think I may need a controller

Not sure why you can't just plug these into your current miners since they are running already 24/7 (I would hope)

I don't recomend the wiibox or lightening asic controller.  People have had much better luck using PC's or RPi's

Not sure why you can't just plug these into your current miners since they are running already 24/7 (I would hope)

Guide is here: https://bitcointalk.org/index.php?action=profile
Not sure if you realise it but that's a link to my profile,not an actual guide.You should take a closer look at your links next time before posting.
Would adopt a Raspberry Pi except I don't know how to use one for this purpose so I thought one of those controllers would give me a better chance but I guess I'll have to look into buying one of those mini PCs instead (with Atom CPUs and run windows) so I can finally free up my MacBook Pro for other things and retire that noisy,hot GPU mining rig (old desktop) :)

The controllers get a lot of bad reviews for reliability.  It seems to be more stable running on a bit higher end hardware.  There are simple guides for installing on windows/linux/pi all over.

I can say that without a doubt these things are easier to run WITHOUT the controllers. I've been going back and forth with 12 of them and a controller ALL DAY. They will connect and mine for some period of time then out of no where disconnect while still drawing full power form the wall..

I think I'm going to try to dual mine with a PC and if that doesnt work I'll go back to single mode and mine LTC only. It sure would be nice to have 200ghs of BTC mining though. :(

Anyone has experience in how many you can run off one computer? Say I can find one or several USB-hubs , how many will run off one pc? I read they suggest 10-15 per 1 raspberry, but I have several mainboards/psus.

You guys think 100 per computer could be possible? 11 USB hubs with 10 ports and own powersupply should do the job. Thoughts?

Isnt there a 127 device limit on USB? Dont know if thats per controller or within the OS though.

I've got 20 running on one PC right now and they are all working great. One things I've noticed for those of you running cgminer to control these things. My pool was reporting about 75% of what cgminer said my speed was. After switching back to cpuminer (one instance per miner) I'm seeing average speeds of 355khs on my pool now.

I think its or the controller, but i imagine windows itself can only handle so many.

keep in mind the bandwidth. 100 gridseeds sending a few kb back and forth would overwhelm the capacity of USB2 controller and likely cause some bad latency issues

Probably go with zoomhash. His prices are actually pretty good considering importing is around $150 for 200+ units and worrying about customs and import tariffs
$150?  Isn't it $160 before shipping/import costs?

Can an electrician help me out.... or armchair electrician! :)

I'm trying to figure out a custom power setup using ATX power supplies for Scrypt mode only. Would something like this work????

Utilizing 12v PCIe Cables:
PSU -> PCIe cable -> PCIe 8 pin to double 6 pin Splitter (could be replaced with 6 pin to 6 pin splitter if neccesary) -> Two PCIe 6 pin to double 6 pin Splitters -> Produces 12 hot and 12 ground wires after cutting off the ends -> 12 barrel plugs per PCIe cable

Utilizing 12v Molex Cables:
One 4 pin Molex Cable with 3 connectors -> Splitter all on three connectors -> Produces 6 hot and 6 ground wires after cutting off the ends -> 6 barrel plugs per Molex cable

Utilizing 12v 8 pin CPU Cable:
PSU -> CPU 8 pin cable -> Produces 4 hot and 4 ground wires after cutting off ends -> 4 barrel plugs

Assuming I used a Corsair CS750M PSU (http://www.newegg.com/Product/Product.aspx?Item=N82E16817139061) it would have:
Four 8 Pin PCI-E Cables -> Splitter -> Double Splitter -> 12 barrel plugs each -> Powers 48 Gridseeds
One 4 pin Molex Cable with 3 connectors -> Splitter all on three connectors -> 6 barrel plugs -> Powers 6 Gridseeds
One 8 pin CPU Cable -> 4 barrel plugs -> Powers 4 Gridseeds

58 Gridseeds total powered @ 10 watts each = 580 watts = an efficiently loaded PSU imo. 8)

There is 62 amps on the +12 v rail of that PSU... by my calculation up to 744 watts. So I could probably power more gridseeds if I wanted to? Any ideas of how to add more units easily?? Possibly by adding more connectors/adapters?? using the ATX connector? I liked the idea of using splitters because I can just cut off the end and jam them into the barrel plug connectors pretty easily.

Adapters/Splitters/Barrel Plugs Used:
The 8pin to 6 pin adapter: http://www.ebay.com/itm/NEW-PCI-E-8-PIN-TO-PCI-E-6-PIN-Y-SPLITTER-POWER-CABLE-6-MADE-IN-AMERICA-/251342990721?pt=US_Power_Cables_Connectors&hash=item3a8535ad81
$6.50

The 6 pin to 6 pin adapter: http://www.outletpc.com/jp1932.html?gclid=CNvu3ZXQlL0CFSNp7Aodmh0A2A
$0.99 each

Molex splitters: http://www.ebay.com/itm/4-Pin-Molex-Y-Splitter-Divider-Power-Cable-for-PC-Computer-PSU-Power-Supply-/121280596049?pt=US_Drive_Cables_dapters&hash=item1c3ce30851
$0.91 each

100 for $24.21

Any ideas to reduce costs??? Source the splitters somewhere cheaper, add more adapters/splitters? etc. ???

Note: If you try this, it is at your own risk. I'm not positive this will work but I don't see why it wouldn't...

There is a theory that you can run up to 127 gridseeds per USB controller.

I think it's practical to manually set the limit to a lower number unless you actually have 127 units to test this on.

The next step is to then try and see how many USB controllers your system or motherboard has, otherwise you could just buy a PCI USB expansion card, then you are limited by how many slots your motherboard has.

For most people, this should not be an issue. You could theoretically run 240+ on just one motherboard, on the assumption that there are two separate USB controllers (north and south? or whatever). And an additional 120 per PCI USB expansion card.

The next issue is what OS to run, and RAM requirements. Litecoin BAMT 1.3 runs on less than 1 GB of RAM mining 5 GPUs using cgminer, and it loads on a USB flash drive as well, saving you the cost of a hard drive or SSD.

For me it was about reducing my power footprint, time spent baby sitting GPU's and heat. I've not got 20 grids on a single computer drawing around 180 watts fully operational. Heat isnt an issue at all (I've even disconnected the fans on the grids) and I have not had to baby sit them at all other than changing the version of cpuminer when it was patched for single mode only.

I managed to sell the GPU's I had (which amounted to a bit less hashing power I might add) for more than enough to buy those 20 grids.

I think 240USD for a 400Kh/s miner is pretty fair.

Ok, I agree $/hash is only like 40% higher than a GPU. And a GPU draws 140% more power.

Might be confusing LightningAsic & Gridseed. I thought LightningAsic created the Gridseed miner..
I was reading in their thread that they were also working on a BTC miner:

A lot of people pay for power.

Also current leaserig weighted average is .010 / clevermining .09xx 30 day / litecoin .06xxx?

Even hosted/paid power these can turn a profit.  I prefer GPUs $160 for 500Kh/s low noise.

Do you have a source where you saw a 400Kh/s version or was it just a reading of 400Kh/s?  Depending on the method of speed rating my GS go from 0 - 2.1Mh/s or sit at 326-350

Has anyone in the states been able to deal directly with diginforce.com? I have been trying to register with their site but no luck so far. I am considering driving 45 minutes to the nearest 4 year university to see if I can find someone who will help me translate/walk me through placing an order with them.

Why do you all bother to buy these miners?
They won't reach ROI ever...

240$ investment per Miner.
330 KH/s

Even with only 2% difficulty increasement (unrealistic, realistic is about 10-15%, calculate allways the worst case), you won't reach ROI.
Better buy the coins instead of giving away free USD/Coins to all hardware sellers.

Do you even understand what ROI means?
If the price rises to 1k again.

The one who bought Gridseed Miners gains a few $.
But the one who bought with the same money bitcoins instead of gridseed miners will profit even more.

That's my point. Buying Mining equipment NOW is just plain stupid. The Miners are too expensive compared to difficulty and difficulty increasing rate.

That's just your opinion, not everyone mines to sell for BTC. Maybe some people like to mine different Scrypt coins.
But yes for some people it's better to buy low and sell high.

But I rather buy a miner that I know will have some resell value left when I'm done mining, than try to out smart the market.
Remember that the ASICMiner USB miners still sell on eBay.

I have had ten gridseeds for about a week now and have a unique problem that I think will only be solved by the smart people in this forum.  The gridseeds look like they are hashing according to bfgminer, but the devices are not going “online”.  Of course there is no issue with my system being on the internet itself as other devices are hashing fine and no issues surfing the web. I have also attempted to use different pools to ensure it is not a pool specific or stratum issue.

3.0 usb hub is always NO for gridseeds.
Use 2.0 usb hub or just directly connect 1 or 2 miners to computer & check.
Is the led lights green & red blinking in gridseeds?


Title: Re: Gridseed GC3355 -Hybrid Scrypt/SHA256 ASIC
Post by: Velveeta22 on April 01, 2014, 03:38:39 PM
Excellent troubleshooting.  I did not think to directly connect one or two of the gridseeds to a usb 2.0 right on the mother board.  I will attempt this tonight.

The lights look good.  Green flashes on all ten units in 1 second increments, which seems to be right according to info I collected a few days back:

What do the lights mean?

GREEN flashing LED means - 5V is ON / drive electronics are powered up.
GREEN LED is ON for 1 second, OFF for 1 second.

RED flashing LED - ON 3 seconds / OFF 3 seconds:
Miner Is Hashing / Processing Data.

RED flashing LED - ON 60 to 70 seconds - OFF 60 to 70 seconds
Miner is Not Hashing / Processing Data.

If Fan is OFF and RED LED IS STUCK ON or OFF i.e. not flashing:
12V is OFF - 5V is ON.

FAN is ON but no GREEN OR RED LED's are flashing ON or OFF:
12V ON - 5V OFF.

When first powering the miner on, the best sequence I have found is:

First, turn 12V Power ON
Second, turn 5V USB Power ON
This will enable self test to occur in correct sequence. (I'm guessing)
If you do not use correct power up sequence, various hash / no hash / no shares reported type problems may occur. (I'm guessing here too)

 
A few seconds after 5V USB Power is turned on, the GREEN LED's will start
to flash ON/OFF as written above.
After 12V power is turned ON, in about 60 to 70 seconds,
the RED LED's will start to sequence ON/OFF as written above.

At least it works!  Did more research on the unit and it looks like I was wrong, it is 5v 2.5 amp and each port takes a max of 300 milliamps.  Was not sure if anyone saw that post before I edited to http://www.amazon.com/gp/product/B004F38WT4 (http://www.amazon.com/gp/product/B004F38WT4) which is a 10 port 2.0 hub, 5v 4amp max.  Few more bucks, but an extra 1.5 amps.

It has been a frustrating night.  I disconnected all the units, then I plugged one gridseed into the motherboard usb 2.0 slot.  There was no change.  The single gridseed would not go online.  Then I wanted to try it on my laptop.  I connected a gridseed to a 2.0 usb port directly to my laptop.  Ran the bfgminer, it was not hashing online.

How can it be reporting the hashing locally but not going online and reaching the pool?

Because you can allways find some idiot...
With 10% Difficulty increase, you get approx 20$ worth of coins with 1 gridseed miner @ 350KH/s.

After that 120 days, mining won't be profitable.
Paying 200$ for such a miner is just a waste of money.
You could buy 10x the amount of any Scrypt Coin NOW.

If the price goes up -> you gain 10x more than with a miner. Selling ASICs is most profitable for the sellers.

I just ran across the last paragraph at Crypto Mining Blog on the new 3.99 bfgminer.  http://cryptomining-blog.com/1883-download-the-latest-bfgminer-3-99-0-for-windows-with-gridseed-asic-support/  It reads:

You should be careful with the new release if you are using earlier Gridseed 5-chip ASIC devices that use the CP2102 USB to UART Bridge Controller as these apparently do not work properly with the latest bfgminer 3.99.0. The older miners are beign detected and local hashrate is getting reported, however it seems nothing gets sent to the pool, so for these you should stick to the previous binary that works just fine. For the newer Gridseed ASIC revisions that use the STMicroelectronics Virtual COM Port (STM32 Virtual COM Port) there are no problems with the new release.

I am at work right now, but nearly sure that I have ten of the older Gridsees with the CP2101 bridge controller.  When I get a chance, I am going to uninstall STMicroelectronics virtual com port drivers and install http://www.silabs.com/products/mcu/pages/usbtouartbridgevcpdrivers.aspx.  I will then re-initiate the Gridseeds with bfgminer.  If no shares are reported to the pool, I will move to the older cpuminer binary with the CP2102 drivers and update you guys as to the results.

If the price goes up -> you gain 10x more than with a miner. Selling ASICs is most profitable for the sellers.

That's why you just point your gridseed miner at a multipool, which is always switching between the most profitable coins . . . .

Also, the keyword you used is if. If the price doesn't go up, you're out your money. With a gridseed miner, using only 7kw/h is more cost effective than mining with a gpu. Many people have bought coins from exchanges only to see the coin die or drop 50% in value. At least with owning a gridseed miner, you still have the hardware to continually mine other coins at low cost so long as scrypt coins are still out there.

Also, as long as you mine the right coins at the right time and sell at the right time, you'll make you for the cost of the miner plus some.

And again, Im sure a lot of people using asic miners are joining multipools to recoup their costs quickly. IPOminer has brought in good profits just by mining, holding, and automatically switching coins to hold and sell later.

You guys should really try the new LightningAsic V3c miner software if you haven't already, it's designed to do one thing and one thing only, to get the most out of your Gridseed miners. If you don't have a Tp-link 703N, they are really cheap to get on eBay @ ~$20. Definitely worth the investment.

This was my second PSU of the same model.  What I did not realize was the PSU must be connected to a motherboard in order to turn it on.  My assumption was that the unit was powered up when the switch on the back was flipped on.  I was mislead by the green flashing lights and local hashing results on the miner screen.  Clearly the USB cables were powering the LED displays.

Once I moved the four pci-e power connections to the primary PSU connected to the motherboard the fans started spinning on the gridseeds.  I upgraded to bfgminer 3.99 and the units started hashing at the pool.  I am a nOOb rig builder and just wanted to share my solution so that others can double check the power supply!

I'm finally tempted to pull the trigger and purchase my first miner. I wanted to start small, but I realised buying a pure SHA2 hasher means I am going to get left behind pretty quickly. For that reason, something that can do scrypt makes more sense. Does that thinking make sense, and if so, do grid seeds still make sense? Some people above say yes, some people say no. I think thats the same for all mining equipment though no?

Hard to answer really. It's all just based on speculations. You can just guess what the BTC/alt coin value is going to be in the next few months. The same with the resell value.
And who knows when KNC titan will be released?
But I'm pretty confident these miners will have a good resell value since Gridseed is a known brand.

Another approach you could take is to mine specifc scrypt coins that you believe in and hold them for awhile.
But like someone said before, why not just buy the coins then?

The reason I brought 3 gridseeds are mainly because I'm interested in the technology and from every purchase you learn something. You learn from mistakes too you know.

I'm thinking about buying a gridseed miner since prices have basically halved since april, but my question is this: Do you believe purchasing a gridseed miner is worth it at this point? Scrypt coins are on the way out since most new coins are adopting different algorithms to combat the miners. If this is the case, if there a good ROI or will only those with the super miners (just as with the sha-256 super rigs) get all the coins?
