So according to that article, it is horrible at FP ops, and the 7970 beats the pants off of it in that benchmark. Wonder if they compensated by giving better integer ops? One can only hope....

Why do I always see Newegg boxes off in the corner of these builds? Yes that's right - because Newegg is AWESOME!

Wait, hold up, does that say Paypal?
EMC offers a PayPal cashout option, and they must have made it work with the API.

Nice find. Definitely obvious that they are targeting the absolute noobs. That application when released will blow all other FPGAs out of the equation. Hopefully it will support other pools later, although EMC is of course an excellent choice, and Inaba is right next door to assist with compatibility issues etc.

RJK you rule this thread with an iron fist man - you order like 10 of these or something? lolwut no, I was kidding you If I had the cash, I would have been in at half price, but didn't have any to spare. Shame, I have a nice rack they could live in.

Know what you 15A worried guys gonna do ?
Convert your 110v outlet to a 220v by adding a breaker to the neutral and be done with it!
That's a 10min - cost nothing job. As said, we talking 15k$ per box ,,, just call an electrician !
Sure. Just a few notes: a) The breakers must have their handles tied together, per code. Easier to just get a dual pole breaker. Few bucks extra. b) The neutral wire must be clearly marked on both ends to show that it is hot. c) You must replace the wall outlet with a 240-only receptacle, such as 6-15R or 6-20R. Few more bucks. 1) If the wiring is 14 gauge, you must use no more than a 15 amp dual breaker, and a 6-15R receptacle. 2) If the wiring is 12 gauge, you must use no more than a 20 amp dual breaker, and a 6-20R receptacle. d) This assumes that the rig supports 240v, which it should if it is using a standard PSU. You may need to chop off the plug end and install a 6-15P or 6-20P plug. Hope this helps anyone that is planning to be cheap with their infrastructure upgrades.

Wait, what? 80plus is old news and all you find on the official list is consumer parts? Eff me running
Click the 230volt tab, all the non-consumer parts are there.

But its a btcasic not a btcfpga... lol

Beautiful. Those test loops look a little kinked, hope you will be using unkinkable hose for the final run. BTW, how much flow restriction should I expect from a waterblock? I'm sure normal pressure shouldn't be more than 1-2 bar, but when sizing everything up, the pump expert wants to know how much actual restriction there is, and I can't find anything relevant in the tech specs.

Gigavps's was at 30ghash for a while a few months ago, but since then he has added BFL singles to his arsenal, so I'm not sure how high it is now.

I think that archive.org is a very good example Yes that is a good one, thanks for pointing it out - I wasn't aware that they had added a Bitcoin donation option. Looks like more than 500 BTC have been donated to them since about December 2011.

He seems to think that it must be offered as part of the "checkout" process, potentially confusing noobs. Someone needs to tell him that they can be accepted without any kind of "checkout" needed, and all he needs to do is post an address. Could point him towards erowid and others for examples.

I still want my magazine =(
I got a U-LINE catalog this morning, so I can wait another month. (But just one more month, then I have to go back to reading deodorant labels) Bleh. Get me the Northern Tool catalog, and then we can start talking. After that, I'll be looking at the Newark/Farnell volume, and then finally I should get my Bitcoin rag mag to read.

Wow...since eclipse is down again, I can see what is going on...GPUMAX is allowing my miners to connect submit shares for a very short time, then forces a disconnect, and bars that miner from getting work...
Does it though? If the miner were blocked outright cgminer should failover to another pool, but it always seems to stay connected and go half as fast.

They're making these for less than 300. The spartan double boards cost about $370? less? to make and these are previous generation chips.
Most likely the initial power estimates were based on 45nm and sometime during the process they got a line on some cheaper chips and thus the giant leap in power consumption. When they run out, the single ver. 2 will be announced, for delivery in 4-6 weeks.
You have some proof of your numbers? I'm sure everyone here would love to see some hard facts. Lets start with the chips themselves, perhaps you know exactly what they are and how much they cost? No? Then stfu. Spartan 6 chip = 150-160 confirmed. Total double board cost =$370? reasonable estimate. BFL selecting something older indicates they got a better deal. Estimated power consumption going from 20W to 85W indicates there was a change in plan. single ver.2 will be the elemental part of the mini rig box/rig box that is estimated to achieve similar mh/w to 45nm chips and is being discussed now by bfl themselves. eldentyrell has all but debunked the assumption of a Spartan 6, and has posted a 10 BTC bounty in his thread for the output of the JTAG pins. I'd trust his judgement first, but I'd also like to see someone get that info and give it to him. I don't have the knowledge of how to do so however.

Can't we easily solve this problem by convincing all honest nodes to reject 1tx blocks?
If this happens, the MM has to include at least one other tx to make any BTC at all. This will force him to engineer some sort of solution to verifying transactions (supposedly he isn't verifying now due to the cost of managing the blockchain). Either he will give up or he'll start including transactions.
thoughts?
What happens when no one sends a transaction, and there are none to include? Why couldn't the miner include 1 or 2 txns of his own in each block to pad it out to the required minimum? TL;DR, NO. Won't work.

Just to provide a little technical insight in case it wasn't known to some previously, both the difficulty adjustment and the reward drop are based on a number of blocks passing, and not on a specific timeframe. The difficulty adjustment causes that time frame to remain somewhat steady, but it won't ever be exact.
