Are you planning on contacting TMC (eldentyrell) and providing him with stuff he needs to make his bitstream compatible with Cairnsmore1?
We have had a conversation but it does need some work from our side that would take from our bitstream progression. So it's not likely to get us there much faster that our own approach. so for the moment we continue as we are. I will be very surprised if you will be able to produce a bitstream of 220MHs+ performance in a reasonable timeframe (1-2 weeks). From what I've heard, it's a pain in the neck to work with Spartan-6 in such high performance application. I believe TML would be much faster to implement. I personally would just prefer a 750-800 MH/s firmware to get my boards running. After all that's what I was sold on (double Icarus performance for $640). Any additional work would be icing on the cake. |

I'm not sure why you feel like making the entry cost to mining lower is going to drive less people to enter mining.
If current GPU and FPGA rigs/farms are shut off, difficulty will decrease and the profitability of mining will increase.
Your naivetι is amusing. You think that $150 jalapeno is going to generate any significant portion of BTC? If BFL is able to meet the demand and specifications there will be dozens of ASIC based Mini Rigs and hundreds of ASIC based singles. I agree that it is a big if, but, if they do then all of us with medium-large GPU farms are going to convert and the guys with a dinky $150 jalapeno will be left fighting over fractions of a BTC/day. Better hope BTC spikes in price. In the end this sort of advancement is just going to consolidate a great portion of hashing power into early adopter's hands. I personally am playing the waiting game but I am eagerly watching for the first sign that it is time to dump my $500/month powerbill. |

After reading about the difficulties in the tricone mining bitstream I was wondering when someone was going to bump the voltages a bit to solve the instability issues. Perhaps you should chat with eldentyrell and beta test that?
Curious how the MH/w efficiency will be affected with higher voltages and core clocks. FPGA overvolting might make watercooling something to consider. More likely though would be an immersed solution in fluorinert(which can be found for cheap on eBay from time to time).
edit: my mistake, you're one of the guys trying to get eldentyrell's bitstream working on a ztex single.

One rumor I heard was they could replace the chips with ASIC and re-sell them.
That would require making their ASIC pin compatible with the FPGA they build their original PCBs on. Why limit yourself to these constraints when the PCB and active/passive components are cheap? |
|
|
|
|
Well, if they bought used FPGAs for $x USD per FPGA, perhaps they can resell them for $x/2 USD or some other fraction of their original used price.

URGENT NOTICE FOR GPUMAX/BACKUP POOL USERS:
I will discontinue support for backup users, this includes GPUMAX users and users who only use us as their backup pool wherever they mine otherwise when the next payment cycle start Thursday June 28, 00:00:00. I am busy working on a whole new upgrade that will be able to support on/off users such a GPUMAX / Backup users along with the Dedicated miners however I will not have it in place along with other changes by Thursday.
Dedicated miners can continue mining as usual and I will keep the rates at 110% right now for you however if you are a GPUMAX/Backup user and end up using Bonuspool on Thursday onwards you will have to either continously dedicate xGH to Bonuspool or stop using Bonuspool since I will be enforcing for the first time the anti-hopping policy with regards to Bonuspool which I have not used once since the start in February.
Right now while I work on scaling the pool I am more than happy just to deal with dedicated miners who keeps a continous reliable flow to the pool and in return I can ensure the best PPS rate along with the best performance I have to offer.
So to recap:
Dedicated miners you have no changes coming your way. Keep your hashrate stable without obvious fluctuations and you will be fine.
GPUMAX/Backup pool users you should stop pointing your hashes at Bonuspool on Thursday 28 June 00:00:00 and if you want to continue you can become a Dedicated miner by pointing a steady flow of GH at Bonuspool without obvious fluctations which I will be looking out for this time around and you will be penalised according to the original signup email.
Hopefully I can resolve the scaling fast and bring both types of miners back onto the pool however for now its just not possible with the current setup.
Feel free to email or PM me if you are unclear about the changes mentioned above and I will be happy to clarify it personally.
That's fine by me. I'm sure it is too early to ask but do you have any idea what this rate would be? |

So you've got an older Icarus build running at full speed on 1 FPGA of each pair on the boards?

Liking the power board. When it is available will it be possible to just add those to our shipments if we request/pay for them?
Actuallly I was looking at the post before. Yes that's very much the idea that you can do more or less what you want with the wiring. It's always difficult to get PCIE leads to wire up nicely in a rig always the wrong length and it's hard to split them nicely. Hopefully this board will be of use here. I imagine it will get used for other non-Cairnsmore uses as well. ATX PSU are hard to beat in efficiency terms and high power at a reasonable cost.
The plan is that this is an initial version and we will follow up with one supporting Ethernet as well. That enhanced one won't be done for 2-3 months yet. Depends on how busy we are,
Currently your board only limits 24pin and PCI-e connectors, i want to know why? Every PSU still has 2-3 molex 4-pin wires (i'm counting only wires because other connectors share the same wire are useless). Why not maximizing the available wires of a PSU? to save few bucks cents on the connector? Most powersupplies can be maxed out on PCIe and +12v EPS pins. I don't know why you're throwing a hissy fit over obsolete and bulky 4-pin molex connectors. The better question is why aren't the 8-pin EPS connectors being utilized. Its not hissy fit when there are other enterprise PSU that we can use. The 4-pin molex is still very popular outside of PC. Most enterprise PSUs that I have seen are 12vdc bulk powersupplies that then feed an in-chassis 5vdc and 3.3vdc power supply that steps down 12vdc. Then again your idea of enterprise and mine may differ. To me enterprise = rack mount gear. There might be a market for an adapter that could accept a rack-mount PSU and output a metric shit ton of PCIe 6-pin connectors. Problem with that though is you have to deal with 40mm fans.. To be fair, thats how all high efficiency PSUs work now. AC->DC 12v, DC->DC 12v->whatever for everything else. In principal but typically in a rack-mount server that I've seen/worked with there are redundant 12vdc PSUs feeding a single power distribution block. Principal is the same, the hardware layout is different. |

I very much look forward to these boards replacing all my noisy GPUs. Second board is stacked with the first and they're hashing away quite nicely on 2 FPGAs each. Apologies on the photo quality, I'm hungover and barely functioning.  That's what I thought. Hopefully this will be week we move on and show real perfomance at least at about the 800MH/s level if not something more.
Bring on the speed! |

One idea I had was for each jalepeno that comes off the assembly line. goes directly to a mining pool ( I know you don't mine, but maybe you could team up with somebody who does). Each preorder would have a share into that pool. Once there's enough hardware to satisfy all the orders....boom! you ship 'em all out.
Bad idea.. I wouldn't want BFL distracted with powering and housing a farm of boxes. Receive parts, assemble, burn test for a day or two, ship. Their performance with the Single and their horrific PR hopefully are due to being overloaded so don't even consider pulling more time off to manage some sort of group hardware sharing thing. |

Is this simply a case of too much hashing power being directed @ bonus pool? Would be interesting/fun to see a page with server load/throughput stats.

Second board arrived along with the stacking kit. Looking forward to setting up my little tower of power.

I live in Boulder. I hear there is a Bitcoin meetup in Denver but I've never made the trip down there. I mine bitcoins, I hoard bitcoins, but I don't really have much to talk about related to bitcoin.

Noob question here but could I in theory develop a bitstream on the side and use the programming chip on the board to send it to the various FPGAs? I ask as I love tinkering with things and I think I'd have fun getting one of these to hash away at something pathetic like 1 MH/s  |

Impressive. Depresses me looking at my piddly farm compared to that |

Surely this must just be gigavps and he forgot his password for his account. Right guys? Right?!  |
