Yeah. Typical sketchy behaviour from BFL. STILL no information about that chip under the heatsink. STILL no shipping information. STILL no proof they have more than 3 devices anywhere at all. STILL 4-6 weeks delivery. How lazy or incompetent can you get if this is not a long con ? Buy them up folks ! Magic in a box for sure. Efficiency 500% : what more do you need ? |

Want to know the biggest surprise in the Bitcoin community in 2012 ? This will soon be announced as SolidCoin 3.0 !  Even RS coin is better than this insane plan ( $10 billion, really ) ! Still no client ? Fail. Delays after delays ? Yes. Pairing the old banking system ( PayPal ) with cryptocoin ( Bitcoin ) theory = will not work, ever IMHO. They stand for totally different things. |

RDP... lord. Why do you want an entire GUI to mine? You are using command line utilities to mine with text miners from a GUI. That just makes no sense. Why not bypass the GUI all together.
As for dummy plugs, you have that backwards. Windows requires dummy plugs, Linux does not. Linux allows 8 GPUs, Windows does not (unless that's been fixed in the past few months). Windows is an inferior mining platform under any circumstance; there is literally nothing compelling about using Windows as a mining platform.
Refurbished $20 drives fail fairly often... the USB stick, not so much. Generates less heat and takes up almost no power as well.
100% right. Anyone using Windblows for mining is LOL An poster above ^. SSD, really ? |

Hmm what do the 58xx report their name as? Cypress? It sounds like cgminer should default them to worksize 256 instead of 128. Would that be a fair assessment?
I think we should leave it default 128 as I found that works pretty good as it is. |

I make the Icarus work with cgminer. why I do this, because cgminer is pure C. since I will try to run cgminer in a home router like TP-LINK WR1043ND(400Mhz. 32MB memory. 8MB flash). python miner needs much space. for example it's needs about ~10MB under OpenWrt. so for those
kind of device I would like using cgminer. Yeah. That would be quite neat ! I also hate all that python BS and the reason I switched to cgminer in the first place. Python is for lazy programmers who can't code properly IMHO. |

You can install driver & SDK independently.
So you can install driver 11.12 to get the no CPU bug and then SDK 2.1 to maximize performance of 5000 series cards. Be sure to delete any existing bins and run cgminer to compile bins with SDK 2.1.
Know how to do this on Linux ? Or shall I just stick with 11.6 and 2.1 ? Have you tested the difference between 2.4 and 2.1 on your 5970s ? Is it really that much better compared with 2.4/2.5 ? I have 5870s only. Thanks ! |

I am lucky enough to have access to as many licenses as I need, so the cost was a non issue. How ? Thanks ! |

Total BS.
Nvidia has no such hardcoded limit in their drivers like ATI engineers that live in a virtual BOX.
Thanks for the links. Last discuss I saw on this someone linked to NVidia forum where an NVidia rep indicates the drivers don't support > 8. Looks like they do. Still in your first link the guy said "when I get this to post". The second link the company had to write custom bios.  I imagine most miners will be stuck w/ 8 GPUs for the time being. I'm not even a Nvidia fanboy. I just go with whatever is the best offering but I must say this : I am sick and tired of ATI's BS with SDK 2.6 and CPU bugs and export DISPLAY=:0 and all that ... NVidia has always had better drivers but they also have always had beyond horrible integer performance. Sorry to disapoint but unless you see something from NVidia indicating otherwise their int efficiency is likely going to blow (just like prior 3 generations). Still not sure how you have CPU bug and not sure why you are using SDK 2.6 unless you have a 7000 series card. I don't have the CPU bug myself ( using 5870s with 2.1 ) but I was just giving an example of ATI's crap driver problems people are facing. |

I like the paperclip method but this makes the GPUs powered all the time.
What about when they are not mining and the rig is shutoff but the PSU still is feeding them power ( or maybe not ? ).

Screw ATI with their stupid 8 GPU limit and need for xserver to be running  NVidia needs xserver and also has an 8 GPU limit. Total BS. Nvidia has no such hardcoded limit in their drivers like ATI engineers that live in a virtual BOX. http://www.overclock.net/t/486609/gpu-milking-machine -> guy running 6 * dual GPU cards = 12 GPUs http://fastra2.ua.ac.be/ -> total 13 GPUs ( 1 single card and 6 dual cards ) using tweaked BIOS and kernel Somebody needs to let us know if the xserver needs to run but I doubt it. Also no annoying 100% CPU bug presumably as well. Nvidia drivers are MUCH better than the crap ATI gives us IMHO. I'm not even a Nvidia fanboy. I just go with whatever is the best offering but I must say this : I am sick and tired of ATI's BS with SDK 2.6 and CPU bugs and export DISPLAY=:0 and all that ... |

My oppinion if 512 @830 cores could pupm with 150Mhash (os somph like that) than ~2300 cores @ 925 should give us 4.5x150=675 .... cant wait to see that This would be amazing if true. Screw ATI with their stupid 8 GPU limit and need for xserver to be running Does anyone know if Nvidia needs the xserver active during mining on Linux ? Probably not as they are much saner than ATI ( living in a box ). |

Unless your PSU is an old group-regulated design, yup.
I have Corsair AX1200 and Seasonics ( X-1250 ) only so are they fine without that dummy load on the 5V rail then ? Thanks ! |

Having a computer behind NAT that doesn't accept incoming connections is like downloading a torrent while blocking its uploads. If nobody took the time to set port forwarding, Bitcoin wouldn't be as responsive.
While miners create transaction blocks, the P2P network does the work of propagating the blocks to other nodes. In addition the transaction messages when someone presses "send coins" are relayed via the p2p network to other nodes (some of which will be miners). If you only have a few connections, you are relying to just a few p2p peers to relay your transactions to others; if you are highly connected, than many more peers get your transactions directly from you. If you complain about slow block downloading, remember the blockchain comes from other peers; if half of the peers are a black hole, it takes longer to download.
It is also possible for bad guys to create bad nodes that do odd things on the p2p network, the more good nodes there are with full connectivity, the better.
As Bitcoin runs on port 8333, you can only forward this port to one computer inside your network. More than one computer running Bitcoin with uPnP, wanting the same port, will likely confuse your router. Additional clients inside your network should connect to your main Bitcoin using the connect=IP.IP.IP.IP config option; they will sync much faster and your bandwidth use will be less.
- 55 active connections to Bitcoin network
All nice and well but how does this affect solo mining folks ? Lowered chances of finding a block due to lower connections ? |

OK. Now I really am confused. So basically all that is needed is just a mechanism of turning both PSU on at same time  Like this :  |
|
|
|
Is there any benefits to having more than 8 peer connections?
So no benefits if you got 20 connections compared to say 8 connections ? What about solo mining ? I think latency and connections do affect that so it can matter but I am not sure ... |

So the general consensus is that :
-no need for common ground as they have common ground from the power strip anyway
-do not mix and match cables into one card ( e.g. do not have one GPU powered by 2 PSUs and just stick to GPUs powered by individial PSUs )
-still need a 5V load in order to put less pressure on the 12V line ?
Thanks and can someone confirm I got it right ?

It'll stink, Just like all other NV cards. I'd go as far out as it wont get 300mh/s
I am trying to be as objective as possible here. Fanboy comments do not count |

I have successfully gotten 6 cards working, on 3 500W PSUs. I am no longer connecting their grounds (explicitly). I appreciate the detailed discussion on this issue. Hopefully everything remains stable.
Are you running anything on the 5V lines of the slave psus? If not then tell us how long they did last ... |
