Take back the happy part, now after paying Zoom hash 98.00 a piece the things are now 59.00 a piece.
Guess its the nature of the business. They've been working fine.
Only thing is trying to solo mine a scrypt coin with cgminer 4.3.5 (what they're made for right?) it tells me my address (the usuall 127.0.0.1) isn't a BtC address and won't start up. P2Pools and regular pools no problem.
It means pay wallet address on the blockchain put your wallet payout address..the one of the coin you are mining not some random exchange address usually you dont have to so im not quite sure why its saying to do so tbh bfgminer used to look something like this for solo -o http://localhost:8332 -u RPCUSER -p RPCPASS --coinbase-addr PUTTHEWALLETPAYMENTADDRESS In case you don't understand still. Payment address for litecoin for example Lgrz15xNehhkJ6UiQuN7FAzoMKWnRxdZtU so it will payout a block and write it to that address so put the wallet address of the coin you are mining. click receive and copy the address (if its a gui wallet) I belive the correct command line for cgminer is cgminer -o http://localhost:8332 -u username -p password --btc-address PutCoinAddress Do not change the "btc" in --btc-address to the specific coin you are mining because cgminer wont recognize that as a command Don't specify an address when solo mining. If you find blocks, the reward will appear in the wallet after confirmation depending on the coin cgminer -o http://localhost:port -u username -p password Or cgminer -o 127.0.0.1:port -u username -p password The port will depend on the coin. Usually, you have to specify it with username and password in the xxxxcoin.conf in the roaming folder under windows. |

Hi, wolfey, I never tried to overclock to 8MH, the newer blades that are selling for 200$ with the extra upper gate MOSFET solder pads available should be able to reach the 8MH if you solder the extra MOSFET and give all the extra cooling.
I mostly worked on the Zeus blizzard for the last few weeks, but it was disappointing too. Plenty of extra power available, easy overvolting, but a hard limit in the chips and the bypass pins that aren't soldered. And bad cooling that gives high HW errors rate even at stock speed.
It seems that the manufacturers are just looking for profit, and not caring at all for the customers.
The turn over on hardware is so fast they don't really care.
There are a few small changes in the design and in the products that could make them better at almost no cost, but it looks like they aren't interested in listening us.
And when we are asking for the chips to be able to make things better, the price is so high that it will cost us way more to build the hardware than to buy it.
I'll probably switch back on bitcoin mining with a home made Avalon gen 3, since for now, it looks like some ROI is possible, unlike with scrypt hardware.
The limit today for scrypt is around 15$/ MH to expect ROI (and the manufacturers are paying way less than that for the finished product)
For SHA256, the limit is near 1$/GH. I expect that the homemade avalon could cost me something like 0.75$/MH.

Again i asked myself why we have to re-invent this f-----g Blades? For the introduce Price of 3000 $ , they have to offer more! Ok , not for Overclocking , but even if you have some high temps outside , you would get some problems or burned parts under normal conditions. This is more like : "Ok , let us glue some parts together , an look what happens." This mining devices normaly have to checked more than any other casual electronics, because they are designed to run 24/24. And what is about any responsability from manufactor? Nothing! I donīt want to say that Grideed has bad hardware , other firms are surely not really better.But donīt bother , we are all the part of this community , and if YOU are able to sell some parts without any responsabilty and warranty and at high priceses , why not? As long as the "customers" are willing to spend high pre-order prices and they accept , that there is no guarantee, again : Why not? This is what we read everytime : No refunds, restricted warranty , all sales are final.-........ And I contribute to this system too. I received my "overclocked" Blade just 4 weeks ago ( delayed over 5 Weeks), and pay for them 899$ , because i thought : Oh what a beautifull pice of ingeneer! And now for the same piece of ingeneer you get only 300$ , if youīre lucky, and for mining we have discuss this enough. So Who is the bad guy in this race?Arenīt we , the customers, who encourage those firms , to do things like that? Ok maybe they selling a few hardware to those "big fishes" or "minig farms people" , but they are rare , the "big" part , are every one of us.Only if we supply them, they can continue like this.... And just if they mine by themselves, but they only mine "Srypt" like anyone of us and what happens if their mined coins donīt sell anlyonger? Sorry, about this , but i only want to encourage you people to fight for your right, because YOU count.... only if those small people with this small antminer U1 or U2 or S1 or GBLADES , goes offline, how do you think this counts? Just an example,In the sum itīs a real big part. But this is the trick of the big players, let them thought they are small...and they are really small!So donīt belive what they say, that you reach you ROI in a copuple of weeks, if one of them offer you a real big deal , catch this, otherwise donīt bother with. I still belive in cryptocurrencies , because there is a way out of the controlling of banc systems,but only if we realize decentralized mining we have the benefits, otherwhise is like any other system , thay allready exist. I know, to much philosophy for a thread like this, iīm sorry , i hope you guys donīt mind  +1.01 ... I am completely with you, buddy... Do you want to start building OUR own miners...  I am computer electronics engineer...30+ years experience...  J4bberwock, nst6563, happydaze ....are you in... I am ready...! Cheers, ZiG I'm already seriously looking at this and contacted almost all the chip manufacturer. Got no answer from all but one that will.probably ship hardware in a month or so. The few ones that are selling chips like innosilicon are selling them way too high. Just have a look at the price Zeus are offering the chips, it's 30% cheaper to buy finished hardware from them. With chips price under 10$/MH, we could offer a better product than the ones they are selling for the same price or cheaper. For bitcoin mining hardware, Avalon gen 3 seems to be feasible. There is a way to manufacture someth with a fair $/GH ratio, around 1$/ GH. I'm collecting my BOM price at the moment. |

I wont OC so i suppose theres no problem for running 2 S3 with my Corsair CX750M
They are drawing 370watt each at the wall, should be 330 before the PSU. it will be very close to the limits of your PSU. 660watt should be 88% of the rated power for your PSU. I usually like to stay around 80%. |

[Can you supply the part number for the buck regulator component? It's not the big grey square, that's a coil - instead it'll be a small IC right beside and will have a code (or codes) written in ridiculously small letters which indicate the part and manufacturer. Someone in the S3 is going to research to see if we can replace?
http://www.ti.com/product/tps53355same type as the S1/S2 and bitfury units both used. Its a good chip that can handle up to 35-40A if cooled and from a good batch. MATH TIMEoriginal spec: 32 chips running at 0.75V producing 15.75GH each = 504GH at 390Wyou have 2 chips per TPS53355 regulator, 16 regulators total. 480A available at 30A draw 480*0.75 = 360W (assumes other 30W is the pair of 15W fans and the controller) This was what Bitmain assumed would workmy guess is that either the chips are slightly less efficient than thought, perhaps drawing closer to 420W at 504GH. (420W total, or 560A, or 35A which is a point where not all regulators will be stable). Alternatively, the chip voltage is less than 0.75, thus drawing more amps. 35A draw would happen at 360W, 0.643V. A combination of both factors is also possible. gentlemen, start your multimeters! Overvolting to 0.8v should be fine to have 10% extra hashing. It will draw something like 450watt at the wall. 400watt before the PSU. That makes slightly over 31A load on each regulator. With proper cooling, it should be OK. You will be able to clock at 275 and 14ms delay. 0.85v will be too high load: 640A divided over the 16 regulators will be 40A per regulator. Hopefully, my S3 will arrive next week so I'll be able to test. For those who would want to reduce power draw in a few months, 0.72v will draw 270watt at wall while hashing at 430-440 GH/s |

32 chips? Holy crap. One blade in my Falcon has 32 chips and there's NO WAY it will fit into the form factor that they have pictured. So get 4 of those blizzard x6's and restore the voltage/clock and you've got the equiv. of what's in the falcon's/thunders/warmachines.
Exactly what I was thinking. Just get some of these, Voltmod them and you should get really good MH/$. The only good point of getting the x6 and restore the voltage will be that you will get a free smaller miner with it. But it's still far from any ROI unless BTC and/or LTC double or triple their value. The actual miners (any brand) at the price they are selling will make you loose 60-70% of the money you invested before they use more power that what they will mine. That is with 5-6% diff increase. And the time when they will stop to make profit is always between 90 and 120 days. So unless the buy price is cut by 65%, I don't see any ROI. |

Am I mistaken or Zeus is trying to sell mini-blades? https://zeusminer.com/product/pre-order-blizzard-x6/I'm calling mine mini-blade X3 (3 blizzard together), my specs after over clocking are around 4.9MH/s for 180 watt. With a slight down clock and undervolt, it should fit exactly in their specs. If they are doing it correctly, they will even make more profit selling this "new" blizzard since they sell it for more than what we can pay for 3 fury. You can spare at the very least 8 bolts, 8 screws and 2 fans. EDIT: After looking at the product page, they are 32 chips, so basically one hurricane x3 panel with heatsink and mounted as standalone. And undervolted. Nothing new there. Except that now, the price for assembled chips is down to 7.5$ each when they are trying to sell bare chips for 12$ each... Mini-blade with 2 and 3 blizzards would have been nice too, with the same power efficiency and 18 chips instead of 32, but they decided to make all the PCB standard. |

nst6563, if I understand correctly, some of the "unavoidable" HW errors are job discarded because one chip already found the hash.
They should be counted as duplicates or even ignored, but that's the way Zeus implemented them, and I don't think anything can be done software side.
Could it be that sometimes, the falcon finds a hash and there were many duplicates?
But this should also happen with a single falcon, and it looks strange that so many identical shares are worked on with different cores at the same time.
On a falcon with 1024 cores, it would be like 30% duplicates at a given time. Maybe a work distribution error.
A way to have falcon and fury working at different diff settings would help. The difficulty looks really low for the falcon.

I asked myself how they separate the usbinput and the 12v input why this works yesterday only when i plug the 12V too? Maybe the AFB26 is like a separator? And what happens when i change this to a 0 Ohm resistor? Has anyone replace this with 0 Ohm? Normaly the communication part has to work when only the usb is plugged in. But when only the 12V is plugged in the STM must be unpowerd.
As far as I know, the 5v USB circuit isn't related to the 12v power. But if your ferrite AFB26 is damaged, it could be the reason why you have the failure. You can replace it with a 0ohm resistor, at least for testing purpose. I also have some spare ferrites. I can send you 1 or 2 from France for the cost of shipping, shouldn't be more than 1.5 Ferrites are used as a filter for bad quality power source. When shorted, they can act somehow like a fuse, even if they aren't very good at this. They often damage the surrounding components or the copper tracks when melting. I'd also check your USB power source. Maybe something is wrong with its voltage. |

Anyone try changing the crystal yet?
What crystal values would correspond to which baud rates?
I finally got my Fury delivery today, I'll have a look tomorrow with the USB erupter crystal. It will probably mess the communication, but we'll only know for sure after trying. I'm busy at the moment, I still have to try to compile cgminer for rockminer to remove the frequency limit. And next project will probably be the antminer s3 over clock for 10-20% extra hashing power. |

has anyone mounted two units together ?
i plan on running to home depot and getting a few bolts that will help me do this. thinking of placing 2 together and maybe 1 on top of the 2 for a total of 3 units running together
Look for my mini-blade mod. Except for the 2 side panels and a 60mm fan, you don't need any material. 1mm thick side panels allow you to use bolts an screws from the existing fan to attach both blizzard together. And I use the same bolts and screws to attach the 60mm fan. 60x35mm fan is very noisy but gives me the best cooling. They are cheap if you look for second hand HP server parts. Fractal design 60mm 20cfm 17db is nice and silent, but 20cfm is just enough after voltmod. Don't go lower. I'm currently working on a mini-blade X3 design that should be ready by Monday. Triple overclocked Blizzard for 4.8-5.1MH/s |

anyone burn out there fury yet from overclocking? if so at what point did it fail?
The power circuit can handle way more than what the overvolt needs. Zeus even removed one of the power MOSFETs from the lower gate to save a few cents on the build price in the newer ones I received. You should be safe with proper cooling of the 6 mining chips. |

Hi Guys,
I have a Blizzard which died (Zeus have already sent me a replacement), essentially it doesn't get detected by any COM Port on any machine. There is no smell and no visible burn sign of any kind. I have tried connecting to a PI as well but it also won't detect.
Any other options you guys can think of?
Adz
Send it 5o me for free  Other option is to look if the fan spins, if the leds are turning on. After that, check for the various voltages at the test points. Probably the 3.3 converter not powered or dead if it isn't recognised. |

The trouble is the way data is sent to the chips to tell the frequency. It's limited to FF so everything over 381will give the chip something different from what we expect.
Unless we find a way to change the factor used for converting the external clock to core clock, the last option is to use the bypass clock, but we can't do it with the actual board since there is no way to safely connect the pins.
Zeus, send 2 or 3 samples, or just sell me the chips for 1$ each, and I'll show you what can be done with them.
I don't want to take the chips off a blizzard to experiment.

We haven't seen or heard form jab in awhile, does anyone thing he melted his house down?
Nothing melted ... Yet. I managed to sell all my mini-blades, and I only have 1Blizzard left, so I'm waiting for next delivery to work again. Anyway, the bypass frequency will need a custom board designed, and Zeus wants way too much for the chips alone. They are now way more expensive than buying a thunder with the actual Zeus festival prices. Next step with Zeus, except for a custom board design if they sell the chips at a correct price, will be to buy a hurricane to improve cooling and over clock when they will sell them slightly cheaper. I also worked on the overvolt for the rockminer r-box. Works stable, but I need to compile cgminer without the frequency limits to test further on this one. Since I never compiled before, it will probably take some time. |

The code blacklists frequencies above 290 and just ignores your settings, that's why. If you had been using my official version of cgminer and not the fork you would have been able to read that in the ASIC-README included with cgminer but there are as per usual no docs with forks.
Hi, will you release a build with this 290 cap removed or at least raised? With little over volt, the device looks like it could go at least 330, probably 350. I've been stable for a few hours now overvolted around 0.8v with 290Mhz and 45Mh/s and I'd like to test a little higher. I'm currently travelling overseas so unlikely to release anything till I get back, but it's a one line change to the code if you're compiling it for yourself driver-icarus.c line 1499 rmdev[dev_id].max_frq = 290; Thanks, I never managed to compile, but I'll try it. |

Overclocking anyone?
I'm currently working on it, but it seems this thing wasn't designed to allow easy overclock.
Undervolt will be interesting in a few monthes to miinimize the power draw.
Should have the voltmod ready in a few hours, but the buck converter looks almost at its limits and there are no pin to pin replacement with higher amps in TI catalog.
30A rated buck converter, chips powered with 0.7v = 21watt and the R-box is rated 40 watt.
first "easy" resistor for voltmod identified, R55, 10K original value. 5.1K gives around 0.9v. Obviously, if you want do undervolt for less power draw (and hashrate), you can go with something like 12 or 13k. removing the resistor gives around 0.4v, but miner isn't detected by cgminer. Not sure it's related as my r-box isn't detected ervery time I try to plug it pictures and more soon. Edit: Running stable at 290MHZ, slghtly over 35GH/s 50°C. Is there a way to go higher on clock than 290? Even if the readme says we can set the value up to 500, I tried 330,320 and 300. they all reverted back to 270. |
