That sounds really dumb.


You haven't read many of hahahafr's posts, have you?

I love you too.


According to a BFL representative, the reason why they were late was exactly because of those changes to their specs. So no, not as crazy as it sounds.


Didn't BFL say at the time that they'd originally intended to release a post-delivery firmware update which would have taken the specs to 60 GH/s?
That was the original implication. Later followed by apparent hardware level changes to support the increased speed. Hence, the extra delays.

BFL might have originally shipped at their original spec much sooner. Though that train  of logic is broken (or borked) by the problem they appear to still face: namely, sourcing components. They appear to be suffering from a component shortage or late delivery of components [other than the ASICs[.

Actually the latest news is that the ASICs were borked, and that's the delay. Though that is still a component shortage I suppose.

Can you elaborate on this borked thing?

Haha, guess I wasn't the only one, http://betsofbitco.in/item?id=785 is now ~1100 qgree, 100 disagree. Wonder what portion of the payout the johnny comelatelys can get. Can you drop enough BTC on this sure thing to make it worthwhile against early weighted bets? Hmm.


On another note, not sure why everyone is so terrified upon hearing the big scary 100,000 number of ASICs. Did no one previously think that BFL would get more chips in, to fill any further orders? They've always said that they plan to be able to make ASICs until the peeps stop ordering em, and want no delay such as having to wait for another batch of chips to come in. They were going to hit 750TH eventually and more.

Or is this a worry that potentially they will have 750TH in-hand, and if orders dry up sooner than expected, that TH might be used without customers to recoup expenses? That is a valid worry in my mind for sure.

If the forums are down then Tom has a good excuse why he didn't make his announcement on Tuesday.

I kid (or do I?), could be anything, server death, ddos, even the PR guy didn't know. Just gotta wait and see what happens at a reasonable hour for someone to be awake to handle it.

I think we can safely say that no ASIC manufacturer will have devices out by then.
This one is the more interesting one, end of 2012.

If you're really pessimistic, you could bet on them not shipping before April.
http://betsofbitco.in/item?id=701


I'm impressed at the No Shipping before end of 2012 bet, was created in June? And still even money both ways!

Strange that you can still bet on not shipping before Dec 1st though, as it is now basically a slamdunk bet.

Okay, thanks.  I guess I'll have to wrap some kind of insulating material around it to keep it warm.  Hopefully the motherboard won't cold bug at those temps either (right now the northbridge is 30C and the memory is 12C).

That's ri-dicu-cold. Why not take your rigs inside to help heat your home?

Interestingly, it's actually a pretty good idea to insulate your drives to keep them a bit warmer:

http://static.googleusercontent.com/external_content/untrusted_dlcp/research.google.com/en/us/archive/disk_failures.pdf

Drives between 15-30C fail at a higher rate than 30-40C almost across the board.

Interesting article. It might seem that way at first, but look at the temp vs time graph. Seems that if a lower temp drive is going to fail, it's going to be in the first 3 months. Between 6 months and 2 years, the failure rates are about the same, and beyond 2 years, it's actually a lower failure rate.

Well, across the board, if a drive is going to fail, it is most likely to do so within the first 3 months, it is simply the most likely to do so in colder climates. [3months, 2years) all drive failure rates drop significantly, while cold climates remain the most likely to fail.
To quote:

We can conclude that at moderate temperature ranges it is likely that there are other effects which affect failure rates much more strongly than temperatures do.

Which suggests that at the extremes (Cold and Hot) you do in fact correlate temperature to increasing failure rates, perhaps for mechanical reasons such as hardcore-fs lists. Therefore it does seem wise to attempt to keep drives operating at more reasonable temperatures, and insulating at extreme cold temps like -24C is very highly suggestible.

I don't understand why people want to be mouthpieces for other companies, rather than other consumers, but I guess it is what it is.

I will start by saying that I probably would have been an early "no info" adopter, had I been around at the time, and now I'm fine with being a post first-batch adopter if they ever show up. C'est la vie.

But to chastise investors (more akin to what pre-orders are than customers), for asking a company for easily obtainable evidence that they haven't just pulled a heist is clearly reasonable (albeit a bit annoying).
The fact that I wasn't told my mother was going to be raped if I didn't buy a mining rig has nothing to do with anything. Investors in all fields, especially in new and risky enterprises need constant mollification that they aren't just pouring their money down a drain. This is common business practice.

That you think these companies deserve some special level of trust because bitcoin requires people just hope for the best in all things is more ridiculous in my opinion. Possibly why we see constant scams in bitcoin, that people just throw up Caveat emptor, and call it a day.

And remember, I have no special vested interest in having information in hand today.

The molex 8981 connector standard is 11amp max current, not sure why Seasonic would limit it to 4A under that, nor if that is the standard, but I would suspect not.

The Seasonic rates the 8981 string to 7A because it's a fully modular PSU and those cables have a single pin of a 6pin Minifit Jr provide 12V to the whole string. The problem isn't with the 8981; a non-modular PSU wouldn't have that issue.

The AX1200 is a fully modular PSU as well.

EDIT: One product, the Corsair AX1200 has had techsupport answer 11A for their peripherals:

453  Bitcoin / Mining speculation / Re: [Poll] When will block reward half? on: November 26, 2012, 03:38:38 AM
I think that the block halving will happen around Tuesday(11/27/12).

Difficulty is notching up slightly in 60 blocks (in about 9 hours, 4:30am PST 11/26/12), which is likely to slightly slow blockrate, after which there will be 336 blocks left, at ~6blocks / hr, will be about 56hours, or 2 1/3rd days, so likely about Noon on 11/28/12. But it's not very impressive predicting that with so few blocks left Cry
454  Bitcoin / Hardware / Re: Serious ASIC question - ASIC Manufacturers Please Respond! on: November 25, 2012, 10:38:08 PM
There should be no reason to have to wait that long! Smiley  Though your right - that would definitely be the safest route.

But in 6 months the diff will probably be like 45m lol

You don't need to wait 6 months (unless you think there will be no shipment for the next 5-6months), if they ship anything, as soon as people get their machines there will be a flood of pictures and info and showing off. A week at most to ensure no one is horridly burned to death or hit by shrapnel, and you can place orders fairly happily. You've already missed the early adopter boat anyway (pre-orders filled).
455  Bitcoin / Mining / Re: Using renewable energy to mine? on: November 25, 2012, 09:58:26 PM
I mean buying something like this: http://www.aliexpress.com/item/1472pcs-x-3-95Watt-B-grade-156mm-x-156mm-6-x-6-Poly-solar-cells/543644854.html

and manually soldering them all together, building/sealing enclosures, and wiring them up yourself.

$1500 for the panels, and I'm guessing ~$2500 for all the other materials (electrical, frames, glass, sealant, etc). About 4kUSD for ~5kwh of panels. My house sits at the top of a hill in Maine, and the back roof faces south and has almost continuous sunshine all day. It's ideal for solar, but I don't mind putting the man hours into lowering the initial investment and getting into it as cheap as I can.

Ah China, guess you can get everything from that whacky country these days.

Do you have enough space for all this? Not sure what your final power plan is, but these cells are rated at .613V, assuming you want 12V DC that's still ~20 cells in series, or 10' x 6" (you could make smaller panels and hook those up in series of course), 7kW (5000 kwh / month) of 12V power would require a huge number of 10'x6" strips. Unless you meant 5000 kwh / yr, which would definitely be more doable.

Umm you don't need to run a 20x1 cell grid just to get 20 panels all in series. You can do a 5x4 cell grid, and still keep them in series. This gives you about a 3'x4' panel, and I got plenty of space for 30-40 of such panels, between my house, and my 2 car garage next to the house (whose roof is facing south as well).

Yes, obviously you do not need to make it 20x1, nor would anyone do that. It was simply a simplest case example to explain sizing issues.

The real world scenario would actually be a > 12V cluster (closer to 15-17V for actual usage) of cells in your panel running in tandem with other modules through a charge controller into whatever system you're running off, such that all panels can work efficiently (same output for all series connections). The calculations are then done with Solar-Hours available to you, to garner expected kwh, but that's more than I cared to do in a simple forum post, so I left it to you to figure that out.

Edit: not sure why I originally read 5000kwh, must have been late. 5kwh is easy (even per day), basically no power at all. Can do that without using much of a fraction of your roof. You certainly don't need 1500 cells to do that.

I got my son one of those mini PC's Foxconn. It has a tiny footprint and uses almost no power. Would be great for a miner setup.

raspberry pi ftw  Grin

have they fixed the USB issue that people are suggesting would impede using Pi w/ ASICs? Obviously a $50 alternative would be preferable to $150, but only if it works.

"High" is 25 to 30 c / kWh. This is what we pay in parts of the world that still rely to a large extent on non-renewable energy sources while still trying to reduce our impact on the environment.

Do you have a lot of renewables in your area?


You sound like a fellow CA brotha, unless there's another part of the world as bizarro as my state.

I think this is just josh being a douche, but I don't really take too much umbrage with this because apparently Tom has been a huge douche too. Basically both companies are acting in a far more immature manner than I'd like to see out of the keyholders of the future of Bitcoin mining, but what can I do about it, just a lowly end-user.

That said, it's obvious that BFL can and will not change their design to meet the new standard set by bAsic, for their first line of ASIC devices. Which is fine really, BFL has the Watt/Hash advantage, now it seems bAsic has the $/Hash advantage. People get to choose which they value more, short-term or long-term incentives (or mix and match). They both have merit. If they unleash a wave of slightly superior asics at the same price point immediately after shipping their first gen though, that will certainly be unfortunate.

I don't think BFL will, or should advocate overclocking their devices after the fact to meet competition, murdering ASIC chips will not yield happy customers, and if their lifetime warranty supports overclocked rigs, then you will also create headache in servicing burnt out machines.

All in all though, when your product hasn't shipped, and is months behind schedule, pointing fingers at another product and saying that they haven't shipped so it's all pie in the sky, and you MIGHT ship before them now, is a little bit much.

Guys (and gals), I am really sorry things are delayed. I want these things to ship more than anyone else (seriously, I promise you, I want these to ship) and the delays are just as hurtful and awful to us as they are to you. We would love nothing more than to ship them all out yesterday.

The first batch should be about 20,000 chips or so. More than enough for all pre-orders and then some.

20k chips covered all pre-orders as of 10/30/2012, and had some chips to spare for future pre-orders.

https://forums.butterflylabs.com/blogs/bfl_jody/48-batches-really-we-dont-have-them.html

So we can't tell you if you are in the first batch, second batch, third batch, etc. We don't have batches. We have order dates. We will fill June 23 orders first, then June 24, then June 25.....until we get to your order.

They don't have batches aside from the first big pre-order batch which will be Huh number of units (unknown). After that it will simply be FIFO

Why come to these forums for BFL questions though? Seems like it'd make more sense to ask them on BFLs own forums.
