You can order them pre-flashed for a premium. You can flash them yourself with any programmer.

Just take that $5000 or whatever you were going to spend on an ASIC and buy coins.

I seem to be asleep every time these end. I'll have to stay up late one night to try to win.

It depends how big you are. if you're as big and wealthy as HSBC then you can help out terrorists. if you're a small player then you better not get caught doing anything.

Do you have pebbles ready to ship, or are they just pre-orders?

localbitcoins.com has escrow and you don't have to wait for confirmations

I think vanitygen searches randomly so just run it on both at the same time. No need to link them.

a relatively efficient model can use between 300-400kw/h per year which works out to between 1 and 1.5kw/h per day. If it uses 1 kWh per day that means it can only cool something like 0.85 kWh per day. If your rig draws more than 35 watts this is going to be a problem. |

Why do you use openvpn and not ssh?

Linux is always better.
But if you need windows, I've read that windows 8 usually allows one more GPU than windows 7.

Recently built a mining rig and slapped in 2x7970's Ghz editions with the 1100/6000 clocks backed by what I thought would be ample power with a bargain buy Powercooler 1050w PSU. I almost shit myself when I fired up cgminer and seeing the top card's temp rocket within seconds to 99C before a loud pop and massive bright spark spewed it's way out of the exhaust of the PSU.
It sounds like that card's the problem. I don't think it should hit 99C within seconds. I doubt the PS would cause that. |

Sure, but there's no need for a master / slave setup. Each node can submit shares independently, you're not running anything in parallel using MPICH or anything like that.

Hmm this is very interesting.

The screws and risers aren't electrically connected.
Actually, if you look closely at your motherboard you will see where the grounding circuit in the MB does indeed connect to the case risers and screws. As for the open computers as has been said, they are grounded to PS. Paper is a terrible conductor, as is wood so there is no issue. Plastic on the other hand can be a good source of static electricity. Interesting -- it always looks to me like just an insulated pad, but I may not have looked at other layers closely. |

You don't want multiple grounding points anyway, you want one central ground as best as you can.

Those cards are going to be so inefficient I don't know if it will be worth running them.

I think there was another thread about this. I still think a hardware watchdog timer with a relay would be best. If used with a raspberry pi as host you don't need a very big relay.

Since Avalon released their reference design does that mean it could be used to make 10 chip boards instead? Would that be easier / more reliable than the Klondike design?
Yes, it could be done, however, it would require a dedicated FPGA, as well as a lot of other hardware that is really kind of overkill and adds to the overall cost. There are people making/offering Avalon clones (including hosting options), if that's what you're interested in doing, but it doesn't seem to be all that cost-effective; especially at a lower scale, which is where a lot of people are starting out. I see, makes sense. |
