Ive tried everyone i could find
cgminer.exe --bmsc-options 115200:10 -o xxx -u xxx -p xxx --bmsc-freq 0982
cgminer.exe --bmsc-options 115200:0.65 -o XXX -u XXX -p XXX --bmsc-voltage 0800 --bmsc-freq 1306
even tried to just open cgminer, it keeps saying the pool difficulty changed or something
please help
If you look under devices is the U3 showing up? I ask this as it could be a driver issue zadig sometimes causes some people trouble. So I would start with looking for device. After that focus on cgminer. Long term get a R1 with crazy guy's mod on it. It will reset your zombies and make your life a lot easier.. yea the driver is fine, but whats an R1? The Antminer R1. Its a router/miner/whatever. Someone put firmware on it that will prevent the U3 from going zombie; https://www.bitmaintech.com/productDetail.htm?pid=00020160128085902068wLN3nqWQ06C5 |

Were you the one who bought all of Finsky's GPUs ? They all sold out in like a day.
No, someone swept them. I just wanted some of them. I'm guessing Kotarius could be the one, but it doesnt matter anyways. |

Deleted previous bump. This time i added a bulk price for all 4. 2.3BTC

*shortned again way to long of set of quotes
You are not pushing hard then. I go back to GPU day's and I would push mine hard as GPU companies had amazing RMA policy's back then. I was about making as much as possible, and granted a few times I pushed to far... puff of smoke. But overall I gained more doing this as I was pushing all my rigs.
The thing today about GPU's is you just don't make enough off of them to ROI. You are going to have to sell to get money back. You might make a small profit but you will not make ROI these day's GPU mining.
Huhh, so i would push them hard actually and they would crash. No damage done, lower clock by 5mhz step until it stop crashing. I keep them at 65-75C, i never had a problem. Sound to me like the GPU's VRM must of overheated. Happens if the heatsink doesnt cool them down. It was not overheat trust me. I remember one GPU as soon as I set it up on intensity to high... instant smoke out of cap on it. I kept them all cool so was not a issue there, but I pushed them hard. It was directly related to intensity of GPU settings. They might have made it harder to do now I have not kept up with mining with GPU software, I'm would guess it has changed some in past few years. I had all the proper risers to get more space and spread them out, there was great cooling. So no issues on heat did not cheap out when making the rigs back then. Well i remember in the Scrypt era, i heard a few people break their GPU's, but when i did tests myself, my 280x would do 745Kh/s and if i took diff from 13 to 18, they would work insanely high, get 765Kh/s but pool side there would be not that much of a difference. Imo i dont think a 2% speed difference thats not even fully effective is worth doing high intensity vs low. Certainly not worth the downtime of having to RMA Gpus. But thats just me i guess. the comparison is a bit off because ETH is skyrocket at the moment, you should have compared the two whne bitcoin skyrocketed to 500 and the diff was 100B
or compare the two when ETH was at 360k satoshi
Its plenty comparable, i been mining ETH for a while now and even when it was crashing low, it was pretty close to S5's profit on a per watt profit. |

I understand what you want to say, but your comparison is not entirely right.
First, you compare used card with new miner. Prices for such used cards are mostly higher.
And Antminers are usually rock stabil - this is not possible to say for GPU mining (I had in the past various 200 GPUs).
I had a lot of defective cards, very often I had switch on/off my GPU rigs.
Also GPU rigs are not so compact as Asic miners.
Wat. S7 used or new is same price, we can take a Used S7 priced at 800$ too if you want. And i dont know what you're doing to your GPUs but i got 0 failure in years. We can also take the price of a brand new 280x if you want, which is only 40$ more. The math is roughly the same. Aprox 20% of my 200GPUs within one year had some problems/defects. With Asic miners this number is much much less. I wonder what GPUs those are. That is an INSANE amount of failure. It is not insane amount, it is common, when running 24h 1 year with a little overclocking in the room with high temp mostly it was: MSI R9 270X, MSI R9 280X, Sapphire R9 290X (but also some trouble with Gigabyte R9 280X, Asus R9 280X) But fortunately, most of them were in warranty. I've had all of mine running 24h for 2 years now and i never had a failure, just annoying fans. 40 failures out of 200 is insane. I'm not sure what temps you were running them at though.

Can those amd r9 gpu's be running without a computer within it?
Is only this thing needed to mine cryptocurrency, or also other things get involved?
Its needs to be inside a motherboard whic his basically a computer. You can mine any type of coin with GPUs, even Bitcoin. I heard that if u use gpu's to mine coins, that after a few years they will be dead because it ran too long on max power. So it basically dies, is that treu or just a story? I run as many as 24 gpu's back in the day. if you underclock and undervolt they will last.but eth may not last as most alt coins do not last So you are saying that gpu mining is only for ethereum, please tell me why. I don't get it, why it is better for eth then for bitcoin? What is actually the difference? Algorithms and asics, so think of it like this a Bitcoin pays for doing Math type A (we will pretend it is division) and Ethereum does Math type B (we will pretend multiplication). A GPU can do all types of algorithms, So lets say it can solve 15 million division problems a second or 3 million multiplication problems a second. That's fine and dandy, but then comes out machines that ONLY do division and that is it. They run the same wattage as a gpu but do 300 billion division problems a second and the difficulty of having the winning answer in time with gpu is lowered. Now it is so much lowered it is nearly IMPOSSIBLE but the amount of electricity to run that graphics card is not changing. Now Ethereum is running the different algorithm (so again pretend multiplication) while there are no machines made to do ONLY (yet) multiplication the graphic card is the only way to do it and mine ethereum. The division machines can not do multiplication and never will. Understand? Nutshell version: GPU does everything, but its extremely slow compared to circuit and processors solely designed to hash a specific instruction over and over. There are no ASIC for Ethereum's algo, therefore GPU is very profitable for it. |

Eh maybe I should turn my amd rig back on, that or see if the maxwell cards I have been stocking mine it as well.
Well you missed about 3-4 months of good profit with them tho. The thing with Maxwell is they work fine but while they take half the power consumption they also hash at about half speed. So you're left with a low $/GH ratio. But if you already have them on hand... yeah check it out. |

I have 2 ASRock H81 Pro BTC motherboards and two open air GPU frames. The frames are stackable. I'm located in the US but these frames are durable, lightweight aluminum. They weigh only a few pounds combined, so shipping should not be overly expensive. If you're interested let me know and I'll send you some pictures when I get home (I'm at work right now  ) I also have 10 powered risers, 3 that take molex connectors for power and 7 that take SATA. Well get me a price, then i'll compare to other offers. I only need one mobo. Do you have CPU/4gb ram to go along with it? If its cheap enough it could be worth paying expensive shipping + duty. I'd need 5-6 risers to go along with it. Edit: Oops, give me an idea for the rack, too. But yeah i dont have the dosh to build 2 rigs right now, maybe a second rig next month tho. |

Just a generalization of how badly Bitcoin mining has gotten that GPU mining became profitable again.
<image snip>
Interesting comparison. however, where you see these prices for R9 280X? I see ~$240 on Amazon for new and ~$175 for used. Refurbs are ~$150 I am thinking, maybe to do some Ethereum mining for fun, but I could also simply buy more ETH. I did buy some in early January and some after trading begun and quite pleased so far to say the least. eBay. Took the average for the 7950/7970/280X which are the best bang for the buck for Ethereum. The brand new cards, aren't that much quicker. They really arent, i'm not sure what's up. The only difference is more RAM, so it could mine Eth longer. But we dont know what will happen to Eth in the future and it might switch to POS before we can cap out the 280x anyways. I probably don't know what to look for, but i don't see the prices that you mention (i see initial bids with these numbers, but nothing like this in buy it now). Well, i just find out that my PC with the highest PSU power (300W; HP 500-267c desktop) can only support GTX 750 Ti, but not R9 280X. If you guys know, would it be easy to hook up Corsair 500 or even spare EVGA 1300 to the card? I never did anything with GPU cards before, so please forgive my newbiness in this department. maybe something new to play with as bitcoin mining is getting depressing lately. Depend what the card is but i run a 5 280x rig on one 1300. Multi PSU is not a problem with the mobo connector y splitter or you could also power everything at the same time using the surge protector switch. For the price, he prolly refer to this; http://www.ebay.ca/sch/i.html?_from=R40&_sacat=0&_nkw=r9%20280x&LH_Complete=1&LH_Sold=1&rt=nc&_trksid=p2045573.m1684As you can see it comes down to about 160$~ Shipped. |

Check craigslists / kijiji for the GPUs. They will be the cheapest option right now but you need to do it before everybody catches on to the ETH mining and they will be sold out. $150 I paid for a few 7970's, $170 for a few 280X, etc. Couldn't get them any cheaper. Some people really think their GPUs are gold and are selling them at the same price as a brand new 380X.
The motherboard and CPU you might as well buy brand new, they are cheap and you can always resell them at a good price.
Risers you need to buy on eBay. Make sure they are powered with the +12V/GND lines cut from the mobo end.
To mount everything on? Just buy an adjustable shelf, you can get it at CanadianTire or HomeDepot, around $20.
If you find me some cheap GPU's i'll give you a cut. I already have a solution for mounting, i'm just lazy and would like something more compact. If you have a link to show me what you are talking about, that would be nice. For risers, normally i get them for 13CAD ea from Bitcoinware. I checked ebay and saw much higher prices. I might do that for the mobo kit, i already have an order i can place anytime, just waiting to see if i can source GPU at a good price first (and might as well fish for better Mobo/cpu/ram deal meanwhile, since newegg will take 2 days tops for me to receive the mobo stuff), and on Kijiji it can be annoying because i dont have a car and dont trust people to ship. Yeah generally on Kijiji you usually go to the seller. Very rarely will a seller deliver a product to you. Maybe MemoryExpress has deals on 380 in your area. 300 CAD, i think i would prefer getting the r9 280x's for 180CAD instead. And yeah, i look forward getting my cars to go pickup betters deals. |

How do I run one of these bad boys in Canada with only 120 Volts?
I run mine off 120V, just use regular ATX PSUs that are single rail. However you do need a dedicated 20A circuit to be safe! I use a 1000W PSU (2 boards) + 650W PSU (1 board). Or get an EVGA 1600. I used a 1300W for a while but it was just too close to the margin for comfort IMNSHO! The huge thing is not to mix PSU's on the same hashing board. So you need to power entire hashing board via 1 PSU. So it has been kinda common for 120 to use two. One that powers two boards, one does other and controller. It can work. I like all in one but that is a lot harder to do in 120v area as evga 1600's are high priced. Compare to 220/240 server PSU's its a huge jump in price. But I still like one PSU for all if at all possible. EVGA G2 1300W PSU............problem solved. Got 3 powering 3 S7 for the past 2 months, no issues. Just buy 2 extra dual PCI-E cables for $40 extra for OEM and cheaper for non OEM cables. I have an extra EVGA G2 1300W PSU at a good price if anyone needs 1. Will include the 2 extra PCI-E cables so you can have 10 connections to the S7 at no additional charge. Just PM me. You can use the single OEM 6pin and buy good Y Splitter on the forum for 3.5$ per. Definitively works for S7's, but some S7 really cap out the PSU, so it might make some people nervous to see 1460W at the wall on their 1300W psu. No problem for the G2's anyways. On a related note, anyone know where to get the short jumper cables for the EVGA 1300 G2? they are the female pins, unlike Corsair 750 that you can jump with a paperclip in the master cable. Are you asking how to jump them? You jump them the same was as every other PSU, pin 4 with any ground. Tho all the EVGA's i've bought in a while comes with the neat adapter that jump 3 and 4. |

Thanks, yes prices are in $USD. One of the 280X is going to have to stay with me for now as I am waiting on a replacement fan from XFX. Replying to PM's w/ offers now!
I would not mind too much if the fan get shipped here. Or maybe ship the GPU with the new fan laters. I,ll wait for your reply. |

Do you only have one of each GPU? I'm looking for a couples of 280x's.
I'd like a ballpark price for 280x's, mobo (and cpu/ram if you have it), maybe the HDD too tho my rigs usually run on USB sticks.
If you beat prices from buying locally i will buy stuff.
Escrow?
