Title: Re: Gridseed GC3355 -Hybrid Scrypt/SHA256 ASIC Post by: Sy on December 09, 2013, 11:28:30 AM 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.

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. Title: Re: Gridseed GC3355 -Hybrid Scrypt/SHA256 ASIC Post by: Sy on December 09, 2013, 12:32:21 PM 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

Title: Re: Gridseed GC3355 -Hybrid Scrypt/SHA256 ASIC Post by: Gator-hex on December 10, 2013, 02:33:59 AM Scrypt requires high speed access to memory so I'm gonna say this is bull until there is some evidence it works. ;)
Title: Re: Gridseed GC3355 -Hybrid Scrypt/SHA256 ASIC Post by: senseless on December 10, 2013, 02:43:44 AM 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. 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.

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.

https://litecointalk.org/index.php?topic=2702.msg68596#msg68596 Quote 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 Title: Re: Gridseed GC3355 -Hybrid Scrypt/SHA256 ASIC Post by: Bicknellski on December 10, 2013, 12:00:53 PM Samples?

Title: Re: Gridseed GC3355 -Hybrid Scrypt/SHA256 ASIC Post by: kramble on December 10, 2013, 06:55:55 PM 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. Title: Re: Gridseed GC3355 -Hybrid Scrypt/SHA256 ASIC Post by: Fiyasko on December 10, 2013, 10:52:13 PM Woah!, Now i wonder if Litecoin is going to crash, or skyrocket from the network now having Litecoin mining chips.
Im intrested to see how this turns out... and weather or not i should buy some "cheap" litecoins Title: Re: Gridseed GC3355 -Hybrid Scrypt/SHA256 ASIC Post by: RickJamesBTC on December 10, 2013, 11:21:11 PM 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.

Currently we have a pilot running with 80 GPU servers. We want to expand bigtime. Thanks. That's what you call a pilot? ;D 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 http://middlecoin2.s3-website-us-west-2.amazonaws.com/reports/1M3jtksp1upR33SX1VzeCfH5x9fc6zKykR.html http://thumbnails111.imagebam.com/30123/dcb2da301220045.jpg (http://www.imagebam.com/image/dcb2da301220045)http://thumbnails104.imagebam.com/30123/f4d796301222107.jpg (http://www.imagebam.com/image/f4d796301222107) GC3355 is on public sale.

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? Title: Re: Gridseed GC3355 -Hybrid Scrypt/SHA256 ASIC Post by: Cheshyr on January 16, 2014, 01:00:06 AM 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.

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.

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 $65: http://www.cybtc.com/thread-3226-1-1.html Quote Development board: each 500 yuan chip: 400 yuan per piece, per pack of 1600 yuan four chips This price is only preliminary offers developers, not as a formal reference to the product price. Each person can purchase two development boards, chip purchase of two packs per person. And here is a link to the specs sheet of the chips https://docs.google.com/file/d/0BxFU17PfhOeeaEVlM3Q1VDBlUkU/edit I'm interested to see what happens with these. Title: Re: Gridseed GC3355 -Hybrid Scrypt/SHA256 ASIC Post by: YipYip on January 16, 2014, 04:29:21 AM Guys, i'm italian. here, to build a gpu mining rig, whit 5 r9 280x for a 3.6 Mh/s, you pay about 2000 euro. estimated consumption even undervolting cards, is about 1.4 Kw/h that costs about 5.00 euro/day the Gridseed ASIC, if i right understand, have 5 chips even "usb device" and it can do about 300 Khash/s for a consumption of about 30V. so, 10 device that i read cost 1360$ (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. (change EUR/USD 1.36) (change BTC/USD 850.00) 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. 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 !

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.

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.

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.

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.

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.

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. :'( Title: Re: Gridseed GC3355 -Hybrid Scrypt/SHA256 ASIC Post by: stex2009 on February 02, 2014, 10:37:47 PM How can I buy 10? obviously need better price than 0.45 BTC each.

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 :) Title: Re: Gridseed GC3355 -Hybrid Scrypt/SHA256 ASIC Post by: fasmax on February 06, 2014, 12:01:43 AM Any one know if the GC3355 chip itself will be made available to DIY and open source people?

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 :) i alsoi have a friend in china too, where will your friend get it from?

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.

Can you plug the gridseed to the usb port of a computer without the 12v adaptor? Title: Re: Gridseed GC3355 -Hybrid Scrypt/SHA256 ASIC Post by: Ruben383 on February 16, 2014, 02:15:43 AM 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. Title: Re: Gridseed GC3355 -Hybrid Scrypt/SHA256 ASIC Post by: mxlx on February 16, 2014, 09:15:56 PM Thanks but if you use a power usb hub and only do script you still need to put an adaptor of 12v to each one?

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 :-\.

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.

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.

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. http://cryptomining-blog.com/1165-download-cpuminer-for-gridseed-5-chip-gc3355-asics-with-reduced-power-usage/ (http://cryptomining-blog.com/1165-download-cpuminer-for-gridseed-5-chip-gc3355-asics-with-reduced-power-usage/) Title: Re: Gridseed GC3355 -Hybrid Scrypt/SHA256 ASIC Post by: sandor111 on March 03, 2014, 08:05:02 PM 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...

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. 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 ... Title: Re: Gridseed GC3355 -Hybrid Scrypt/SHA256 ASIC Post by: worldlybedouin on March 04, 2014, 11:05:41 AM 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.

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'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.

Title: Re: Gridseed GC3355 -Hybrid Scrypt/SHA256 ASIC Post by: Dabs on March 15, 2014, 03:36:21 PM 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.

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'm not understanding how it would ever be profitable. 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. this reminds me folks replacing their gpus with asicminer usbs :) Title: Re: Gridseed GC3355 -Hybrid Scrypt/SHA256 ASIC Post by: gsupp on March 26, 2014, 04:53:30 PM Does anyone know where I can get just the GC3355 chips?

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.

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.

Title: Re: Gridseed GC3355 -Hybrid Scrypt/SHA256 ASIC Post by: Velveeta22 on April 01, 2014, 02:42:04 PM 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.

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.

Title: Re: Gridseed GC3355 -Hybrid Scrypt/SHA256 ASIC Post by: Velveeta22 on April 04, 2014, 02:23:25 PM 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.

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.

As I mentioned in the original thread, I bought this PSU: PSU: http://www.amazon.com/gp/product/B00CGYCNG2 (http://www.amazon.com/gp/product/B00CGYCNG2)Version of bfgminer: http://cryptomining-blog.com/tag/gridseed-bfgminer (http://cryptomining-blog.com/tag/gridseed-bfgminer) Screenshot of related system and setup info: http://s24.postimg.org/5b7dovy2d/photo_1.jpg Connections and hardware: USB Cables: http://www.ebay.com/itm/190691293084 (http://www.ebay.com/itm/190691293084) Cable to Gridseeds: http://www.ebay.com/itm/111306458237 (http://www.ebay.com/itm/111306458237) Gridseeds: http://www.ebay.com/itm/201057196108 (http://www.ebay.com/itm/201057196108) PSU: http://www.amazon.com/gp/product/B00CGYCNG2 (http://www.amazon.com/gp/product/B00CGYCNG2) 10 Port 3.0 USB Hub: http://www.amazon.com/gp/product/B00DCO9YVM (http://www.amazon.com/gp/product/B00DCO9YVM) The ten gridseeds you see in the picture are on virtual COM ports 1-10. The USB hub is 3.0 but connected to 2.0 port on the Z87 motherboard. I do not believe there are any power issues or driver issues because the units are connected and hashing locally. They are just not going "online" to connect to the pools. I am going bonkers on this issue and would be more than happy to send a Doge or BTC tip to whomever can solve this issue! 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!

also for those running just a few gridseeds, first price cheapo PSU works just fine, I also run them on a 10$ PSU works great Title: Re: Gridseed GC3355 -Hybrid Scrypt/SHA256 ASIC Post by: ChefBorjan on April 14, 2014, 09:01:06 AM 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. Title: Re: Gridseed GC3355 -Hybrid Scrypt/SHA256 ASIC Post by: amdfxman1701 on May 10, 2014, 07:42:55 PM 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?
