why don't you use Tungsten?

can multiple tickets be purchased by one person....really need another 5830  If you buy the remaining 19 tickets, you're almost a lock to win! 19/20 is a very high chance indeed... 95% |

That price is definitely good for an FPGA miner, I think though the most savings will come from mass production due to the power, heat and space saving costs. If you can manage to get 5 on a board and sell it for ~1k and make it stackable it would not be a bad investment. I'm sure people would put down some serious $$ then.
5 FPGAs alone (without board any parts yet), will suck up the 1k budget already. We aren't trying to sell the boards with a sky high margin, the costs of the parts alone are just quite high at the moment. Have you looked at the microsemi smartfusion devices? They offer a huge amount of gates at a much lower price & you get a extra arm processor. am I missing something  are you asking just to ask or have you compared the technical capabilities of the chips? |

is there a way to buy just gpu components to build a gpu card?
just wondering
if so i have a homemade gpu liquid cooling block idea
sell your idea to card manufacturer. or file a patent then try to sell. since you're gonna make one, there's your prototype. |

I know nothing about games. Newegg indicates this free coupon with some cards.
Does this have any resale value at all?
I won't use it but if it's easy to sell then what sort of price would it get?
check eBay closed auctions |

Dual6870BE's(gaming rig) Very clusterfucked tight packed Both cards run @ 85° for the past three weeks mining, WHILE gaming, No issues
6990 Open case/20inch box fan= 87° running 1month no issues
5830 same case 78° 5months no issues
Dual 6870's overheat at 90° and auto shutdown, I wanna run them at dual 1ghz but i can only run them at dual 981mhz due to heat
Which 6870 are you running? are you able to underclock the memory to low setting? |

A good point was brought up. Time limit.
So, the raffle will go on regardless of how many tickets have been bought by exactly 7 days from the time of the first post.
Good luck! First ticket sold. It's on.

You'd have the same problem if you used random.org, but thankfully there's a solution. Why don't you give each user a different address to send the BTC to?
[/quote]
I was planning on using a different address for payment for each entrant.
I guess I'm just not really understanding how to run a raffle using the method you are suggesting... spell it out for me please.
I'm just gonna use random.org and so that ppl don't think there's hanky panky, I can video capture my screen when raffle winner is picked by random.org and post it on youtube. does this satisfy you?

I'd consider entering if you changed your draw method to something more open. Perhaps something similar to bitlotto's method, which can be seen here: http://bitlotto.com/details.html. That way we can all be sure you're not manipulating the results. I won't be involved in results. i will submit all entrants to random.org (3rd party) and they pick a winner randomly. http://www.random.org/draws/bitlotto seems to be about sending winnings to a bitcoin address (oversimplified overview). I can't send a 5830 to a bitcoin address... or am I missing your point here? It would be impossible to prove that you used random.org to select the winner, unfortunately. Because each entry into your lottery costs 1 BTC, then each entry will have a corresponding transaction ID. That's all you need in order to use Bitlotto's method. Just send the card to the sender of the transaction that wins. OK. How do I know who sent the transaction to me? I can have several people here claiming that they sent 1 btc from some address to my address once the winning transaction is announced. How do I solve this? |

The raffle will occur on time, regardless of how many tickets will be sold. so far there are 4 entries. (updated 8/25/2011 10:41 PM CST)Rules + Prize: entry ticket is 1 BTC Up to 20 raffle tickets will be sold. Drawing occurs when the 20th ticket has sold or 1 week from original (this) post, whichever comes first. I will post the number of tickets available after processing each ticket purchase to keep everyone up to date. To purchase a ticket, please PM me and I will give you an address to send your 1 BTC to. When you send the BTC, tell me what your sending address is so I can associate your nickname with the sending address. I will use your nickname and enter them into third-party draw service provided bu rangom.org random.org will pick a winner and the results are public. I will PM the winner for shipping address. I will not ship outside of US, so if you are not in US, please don't buy a ticket. The card is a 5830 with the bracket clipped of at the bottom. you get everything it came with. if you care about the bracket being clipped off, please don't buy a ticket. this card was used for a few days until I upgraded to 5850s. Here are the pics:  <br>

On optimization of mining algo (be it on GPUs, CPUs or FPGAs) is there a post that describes all available optimizations? This thread gives a good run down of all the optimizations being implemented on GPUs. [/quote] thanks! i did see this before and had lost track of it. appreciate the link. so basically similar algo optimizations were implemented on your fpga code? |

Are you certain? Aren't the LUTs involved in routing too? I always thought that they were either configured as logic or routing node.
I have to admit my understandings of the workings of fpgas isn't quite as good.
LUTs are sometimes involved in certain specialised kinds of routing, but most of the routing is done through a dedicated routing fabric in which the LUTs are embedded. As I understand it this is one of the things that distinguishes FPGAs from other forms of programmable logic like CPLDs. I would so buy one or two but $440 is a bit too much to invest in 100 Mhash. It would take a seriously long time to earn back that original investment. I just picked up a 5870 for $180 and that nets me 393 Mhash/s , so 3x the amount this board does at a more reasonable cost. Yeah, FPGAs very power-efficient but the upfront cost is nasty for every solution I've seen so far. On the plus side, as newMeat1 says you can keep going well after GPU miners have to give up... Edit:But the strongest reason imo is that you can't update asics, so I think he can suck it  That reminds me, an interesting factoid: unless he's been deliberately misleading people, at the time he had the ASICs made he didn't actually know about the optimisation of computing H+K+W[0] in the previous round, which improves performance for free by reducing the critical path (at least on FPGAs). On optimization of mining algo (be it on GPUs, CPUs or FPGAs) is there a post that describes all available optimizations? I'd like to learn about it. Can someone point me to it please? or is the computing H+K+W[0] in the previous round pretty much the only optimization so far? |

I think its been a month since I've seen a new 5830 at a store. They honestly might be gone.
very good! |

I sure hope that by now ALL 5830 inventories have dried up.
it's about frikin' time they stop selling these mysteriously turning up inventories of brand spanking new 5830s.
Be gone! be very gone 5830!!!
Why do you want them to be gone? They're they best bang for buck card? i don't want any more miners LOL also, i have a bunch to sell. when newegg does not have any to sell. I sell at a nice profit. purely profit reasons. |

I wanted to let everyone know that the 11.8 preview makes dummy plugs UN-NEEDED!
Why is this a big deal for me? Because I refused to use dummy plugs since it lost me 3-5 MH/s per GPU so I always just swapped monitors back and forth between cards to spin up each instance, then removed the monitor and left them to mine.
Now with 11.8, I can specify DEVICE=0 and DEVICE=1 without TOUCHING THE MONITOR CABLE!!!!
Fully remote, at last! (don't have to walk in there to plug in monitors when the rigs crash [which is often, due to clock settings and improper vrm cooling])
Uh I'm using 11.7 with no dummy plugs? you don't need dummy plugs with 11.7 and up... can't recall if it really started with 11.6 though... |

Holy crap how lucky was I?
A block was found in 2 seconds. I run at 400 m/hash and I got 1 share out of the total 630. I ended up with .07 BTC. In 2 seconds. Sweeeet.
I was able to get 3 shares in. LOL |
