You mean PCI-e 2.0 x1 slots? If they are PCI-e too, then yes, but You would need riser cables to connect PCI-e x16 card to PCI-e x1 slot (Riser with x16 female and x1 male)
I would suggest using risers x16--> x16 too on those 3 x16 slots aswell.
Hi, Yeah, meant PCIe 2.0 x 1 slots. Im going to buy some risers this weekend. Does the risers I need have to be powered riseres? For either the PCI-e x 16 or PCI-e x 1 slots? I plan on having 3 gpus connected via PCI-e x 16 and 1 connected via PCI-e x 1. I saw people recommending powered ones, why? I don't know, if someone could explain it I would be gratefull  If you use more than 3 cards you should use powered risers. The reason is that the 24 pin connector might not provide enough +12V current to power PCI-e bus. Some motherboards have a dedicated PCI-e 6 or 8 pin connector right on the motherboard. If you don't provide enough power to PCI-e bus, the yellow wire going to 24 pin connector will melt, taking the connector with it. Yes, you can use 1x -1x in any of the PCI-e slots. |

Even if a 1TH/s miner was produced every minute the difficulty would only increase about 212M per day. If we assume an exponential growth rate of 20% per difficulty change, the increase in hash rate would exceed the production rate of miners in early June. The growth in difficulty will become linear.
Why would it be linear? I don't get it. The production capacity of 28nm (or 14nm) products can be increasing at exponential rate. As long as human population increases at exponential (or near exponential) rate why would production (of asics or anything else) not be in step. It has been so far. We still have enough resources on this rock to have a good exponential run for another 75-100 years or so. There will be nothing linear about it in our lifetimes. Babies are born every minute and every minute there is a teenager somewhere who discovers crypto currencies and wants to make some money. |

Did you really just advise someone to look at BFL miners and youre a Hero Member?...thats such a noob move and pretty shameful actually
Are you trolling? Because i don't understand how can you recommend BFL...
Oh God. Here we go again. I swear I'm the one guy on these forums who doesn't hate them. I've been a customer of theirs since the FPGA days, and I've always had good luck with them. They're slow, but always deliver a solid product in the end. Their support has always taken care of me as well. I'm sorry, but Avalon support was a joke. ASICMiner support is pretty much this forum. KNC is ok, I guess, but they're not in the US. When BFL shipped me a replacement PSU, it was at my door 2 days later. Yes, I have several Monarchs on pre-order. I'm not gonna gush all over them, but would you all get off my ass? You'd think I just admitted to worshiping Hitler or something. BFL products are good. Not sure why people bashing them. All manufacturers have/had delays. Monarchs are good upgrade to existing GPU rigs. I'd buy Monarchs, but I got burned with BFL chips so I'm going to sit this round out. Take a look at KNC Neptunes and Black Arrow... |

I've just started mining and have been OC'ing most of my cards using winter air cooling in MI. I can't seem to get the cgminer running for more than 6 hours at a time. I have reset everything to default values and got up to 1 day 5 hrs before one of my Powercolor 7950's went sick....
How long have you guys been able to keep cgminer on for before crashing? Is it common to have to restart the miner every day or hours?
I have 5 7950s on a MSI Z77A GD65.
cgminer is a great program. Just don't use ADL functionality on Windows. Lower your clocks if cards go sick. Use MSI AB to set clocks and fans. Find a sweet spot E/M ratio. Set clocks for individual cards as they all are different, even if they all are the same model and are from the same manufacturer/batch. Different ASIC quality, different clocks. I've had systems that run for months without a restart. Usually restarted by power outages or my watchdog. But most rigs run for weeks without a restart. |

What pool do you mine on? If your pool switches coins, that easily locks up cards. The fix? Install CGWatcher and have it restart mining when cards go sick or cgminer freezes etc. If you mine on a multicoin pool try mining only litecoin (for example) for 24 hours and see if you get a crash....if not then just use the fix I listed above. here is my btc address if my solution works for you 1KnyGG1sySxmCGAD2AAukCWPT8T1o22rhK Thanks for the troubleshooting tip, however that is not a solution because this is not a videocard lock, it's at CPU or chipset level. I've ran with and without CGWatcher. It also happened when a Nvidia 6200TC was providing video or just with teamviewer virtual display driver. The keyboard leds don't toggle and the wireless connections fall from my router wipeout, are you using bfgminer/cgminer ? If so, disable ADL functionality. Best is to recompile without ADL support and set your clocks, fans with MSI AB at the machine and use Remote Connection to start cgminer. If you start cgminer from RDC, ADL will not be accessible so cgminer won't be able to load/use adl libraries. You are crashing AMD drivers (freezes), most likely because of bfg/cgminer ADL code. Or try reaper miner. |

Don't use Internet to access your miners directly.
Use some sort of API aggregation web page (https) to list status of all miners, restart them or power cycle them. Protect that page with user login and https.
Port forward your Internet connections to that page.
cgminer already has all this by default - I wrote it - but no idea if KnC enabled it or not. I meant a page like your api-example.php. If you have 10 miners (on 10 different IPs) and one rPi watchdog. On that watchdog, have a page that would go to 10 IPs and fetch API summaries, format and display. Something like https://bitcointalk.org/index.php?topic=222632.0rPi gpio ports that can be used to drive relays (via a simple transistor driver) to power cycle the miners (waiting for my relays to try this). Got the gpio ports working (set them on 3.3V/off 0.4V), but not from the web server (requires access to sysfs). Work in progress... Something like http://code.google.com/p/raspberrypi-gpio/downloads/list but it uses mySQL, which is an overkill to do this if you ask me. |

Hi all, So, what else to do in my spare time while mining some BTC? Exploiting security holes in my hardware. It turns out that every KnC miner can be hacked within 5-10 minutes, making it possible to control the CGMiner remotely. I've submitted a higly detailed report to KNC, explaining how i did it, and how they can patch it with a new firmware upgrade. To avoid a huge breach, i will not reveal all details, but i give you a short summary [proof of concept]. 1: Scan the internet, using a special tool, for the default KnC Miner header response WWW-Authenticate: Digest realm="KnC Miner configuration", nonce="f76e06a34c00b5fec1da6749d4ed0bfc", qop="auth" EVERY miner uses this header, so in 10 seconds, i found about 1180 responses vulnerable to my attack. Don't use Internet to access your miners directly. Use some sort of API aggregation web page ( https) to list status of all miners, restart them or power cycle them. Protect that page with user login and https. Port forward your Internet connections to that page. |

what kind of power supply you use for 4 gpus?
R9 290x: 1200W for first three, 550W for the fourth one. The rig pulls 1200W from the wall. For my next build, I'd use 1000W for first three+mobo and 850W for the next three. |

I have two systems with that motherboard. One has four R9 290x, the other has four 7950. All on powered risers.
AMD 13.12 Catalyst. compiled cgminer with ADL code removed.

I ordered on Dec 6th. Emailed several times right after asking about the status. I wanted to know the timelines and wanted to cancel the order.
You did not reply to my emails, instead you moved my order to "fabrication" and then send out an update email about delays. I wanted to cancel, at which point you refused. (Calling me a douchebag in the process).
After that email I had no option but to open a PayPal claim. You said that the order will be processed in 8 days. Well, I waited until Dec 20th to update the claim.
Now, you might want to update PayPal claim to indicate that you will not be processing my order and that the tracking number you provided in PP claim is really an internal routing number. From my point of you, you have my money and my order. You tell me where is the fraud.
Just cancel my order and save your face.
BTW, Paypal is investigating. They will probably close your account because of false statements you have already made there.
When you outright lie you make yourself look REALLY silly. You ordered on the 9th, which is what my screenshot from the backend indicates. It's also what your PayPal transaction indicates: Thankfully, I don't have the time or energy to lie and try maintain a lie - you're correct in that you emailed on the 12th asking about timelines, and I apologise for not responding to that, but all I would've told you is that we will ship it within the timelines as indicated on our delivery and returns policy you agreed to during checkout. The email update (quoted above) said nothing about there being delays - please quote the part that says your order will be delayed? I did not refuse to cancel your order, it was already in fabrication by the time you requested it. I did indeed call you a douchebag when I said "Seriously, and without being too disrespectful, you're being a major douchebag." Because you were and you still are being quite douchey. I call a spade a spade. Per our delivery and returns policy ( https://openrigs.com/information/information&information_id=6) that you agree to during checkout, order processing takes 8 WORKING days. WORKING. Not consecutive days, not calendar days. It says it right there. Again - even if we forget about that fact that orders are first scheduled for fabrication and then fabrication takes 8 working days, from the 9th when you placed your order to the 15th when you opened the dispute was 4 WORKING days. In the email update (quoted above) it even had an ETA of the item being shipped (handed over to customs) - the 23rd, which was the 9th working day after you placed your order, and the 5th working day after it entered fabrication. I do not have your money - when you open a claim PayPal immediately reverse the transaction and put the money on hold, so no, I will not let your order leave the country until the claim is closed. There is no face-saving that needs to happen, your order was processed within our expressed timelines, you were updated regularly and efficiently, and your knee-jerk reactions are evidence of a much larger problem that I do not have the qualifications to diagnose. PayPal will most assuredly NOT be closing my account, I don't think you have the faintest idea how businesses operate. Are you saying you will ship my order when I cancel the claim? |

My bad.
Question for you? IRT International tracking # 20934197XXXX, where can I check the status of this shipment.
Ah! I just figured out who you are. Given that there's only 1 PayPal claim (yours), I figured paradiselife was the one moaning about it. I should've double checked that - sorry paradiselife, you can disregard the last sentence in my previous post. Now to back to your question. IRT International is the local agent that deals with all of our import/export processing. The number is an internal routing number (on the customs documentation) that allows us to handle queries from customs. Once we get tracking info from customs we match it up on that internal routing number and can then update the backend of our order system. Obviously, until the PayPal claim is resolved we won't continue processing your order - the risk of being defrauded is simply too great. Whilst I've got you on the line, let's discuss your PayPal dispute, because I'm terribly confused as to why you opened a dispute. You claim in this thread that you tried to cancel your order when it was in pre-fabrication, but we have no problem with cancellations in pre-fabrication, as it's just raws coming in and we can re-use raws. Your email requesting a cancellation was on the 15th, which was after it had gone into fabrication. Here's output from the backend:  So just to be clear - the reason you opened a PayPal dispute on the 15th was because I sent out a general update email to tell everyone that we're pretty much on track, we've overcome our packaging supplier letting us down (by ordering from another supplier weeks ago when we suspected it might happen), and even detailed ETAs for all orders in various brackets, including orders above 915 (which your order was). In response to an email update from the system every few days plus a dedicated mailer to keep everyone in the loop you opened a PayPal dispute, and then in this thread you moan about how it's not like Amazon? Which leaves me a little confused as to what you were expecting - hourly updates? Here's a copy of the email update that triggered your dispute, just in case you forgot what it said: So please do explain what it was about that email update that made you angry enough to open a PayPal dispute? I ordered on Dec 6th. Emailed several times right after asking about the status. I wanted to know the timelines and wanted to cancel the order. You did not reply to my emails, instead you moved my order to "fabrication" and then send out an update email about delays. I wanted to cancel, at which point you refused.

This company is sketchy, no product has been delivered and promises just keep getting made, also you say for the 475-700 batch only? why was I emailed a few days ago with my order being in the 900 range saying it was sent off to customs and you will have a tracking number soon but now only 475-700 is confirmed to have tracking numbers for? which part are you lying about?
I'm not sure I understand the confusion. The entire batch doesn't get tracking numbers in a single shot - they provide tracking numbers as they process them, so we got tracking numbers for the 475-700 range, which is entirely normal given that there were only a few working days this past week. We're waiting on the 700-915 lot, and for those that count in decimal 900 comes after 450, so it makes sense that those that go in first would be processed first. As I said in the PayPal claim, which you opened after your inability to understand our regular update emails, yours is on hold at customs and won't be shipped until the claim is resolved. fluffy, What you mean "yours is on hold at customs and won't be shipped until the claim is resolved"? I did not file a claim in customs in your country. Please explain for everyone.  You're not paradiselife? Your nick is af_newbie. Those are two different people. Does that make it clear? My bad. Question for you? IRT International tracking # 20934197XXXX, where can I check the status of this shipment. |

I am asking because I didn't get a tracking number... duh or I wouldn't be asking
As I mentioned in my previous mess...no wait, let me cut and paste instead of typing it out again: "if it's >450 then let me know and I'll gladly publicly post your tracking number on Monday when I have had a moment to get through the stack of 250 tracking numbers we received on Friday" Have a good weekend! my order is below 450 post my tracking number let me see where my package is openrigs is a scam and I will not stop until you deliver product, I will even open up openrigsisascam.com to stop your scamming business ways +1 He posted a tracking number for "IRT International" in my PP claim. Whatever that means. I did not order a fluffy pony. Paypal and myself cannot verify or check status of my order# 952. POS company, POS customer service. |

After the New Year, we're going to have a full-time dedicated shipping & receiving person in the warehouse and I am here to ensure that we make sure there is less of a communications gap with everyone.
Don't bother. At the current prices, there's no use buying these. +1 28K for 1TH, that is crazy. You'll not recover half of BTCs paid. Don't buy at these prices. Full kits should be priced at $2K. But they are "Fool Kits" so I guess the pricing is right. |

hmm when you guys order? whats your ship date?
I ordered on dec 2nd and my order number is low 800's.. I actually "didnt" receive an email saying it was out of fabrication .. I found out via this thread!
I looked in my account and it says shipping pending customs check. ( Shipped date is Dec23 )
About 20 days after order..
@ af_newbie: Holy crap! $100 shipping.. Did you pay the premium for the fastest delivery available or did you just choose cheapest method?
Are you states side?
I paid $47.73 for International Insured Surface Mail to the United States!
I didnt read anything about 6weeks tho. If it took 6 weeks took get here after the 23rd ship date it would be 60 days or so before item is in hand! Add the customs wait time and add 5-10 days? Mine has been at customs since 23rd! I haven't gotten a tracking number so this is all assumption or going off what my order status says!
If it took 6 weeks + 20 days of fab + 10 days at customs! Thats like a 70 day wait period to receive item in hand after order..
My order has been at customs pending shipping for 4 days .. i just noted 10 days to give cushion but i dont know any more than you guys!
If anyone actually receives their package if you could do us and openrigs.com a solid and post a picture of the said item in the wild!
Everyone else should post their order date, order number, ship type, location and when the item broke out of fab so we can see average delay in time for manufacturing and shipping and from shipping to in hand!
Hopefully they are just swamped with holidays and we will all get our tracking shortly.
3 rigs to Canada, "International Insured Surface Mail" he charged me $100.20 I'll be selling his shit locally the moment I get it (IF I get it; in 6 weeks or whatever). I made my own racks for $25 in parts from a local metal supply store. I wish someone warned me about this outfit. I'll do my best to warn all other potential customers. |
