It's your accusative tone. You don't know what you're talking about, yet you're still postulating that it's all wrong.
It's just a space model, probably a preliminary one. So you can't regard what you see there as accurate.
What appear big capacitor shapes, may turn out to be smaller caps. Power supplies all need big caps.
Compare it to the pics of the FPGA single. The designs are similar.
Why so many VRMs? Are they even VRMs? Will there be that many in the final design? Perhaps many smaller power VRMs are cheaper than a couple of big ones. 60W is 50A @1.2v. That's pretty hefty.
Topic: Butterfly Labs is going to give lifetime warranty - page 4. (Read 7610 times)
As an Engineer, I ask myself what is definition of BFLs "life time warranty"? Is it;
1. The calculated operational lifespan of the circuit board including solder joints, fatigue rates, etc and comes out to 18 months?
2. Is it the industry standard of 25 years = life time?
3. Is it the mean lifetime remaining of the purchaser? i.e. Purchaser is caucasian male with life expectancy of 80 years and he buys it when he is 40 years old, therefore the lifetime warranty is 40 years?
What does the forum think?
More importantly, what does BFL think?

have you ever had memory fail? I thought I did once but it was incorrectly inserted, lol.
All good memory makers give lifetime warranty.
Memory has one of the highest failure rates of any computer component. If there's a hardware issue with a computer it almost always has to do with the ram or hard drive.
Please put the rendering down and step away.
I want someone to answer my questions seriously, I'm not afraid to learn. I don't have as big of a ego as some people on here. Someone who has experience or someone at BFL labs explain what we are looking at?
Maybe I'm missing something but these are my thoughts. I'm not a chip manufacturer or a electrical engineer, but I have built computer systems for almost 15 years. Your 3d model doesn't look right to me, it looks overly complicated. Here are my concerns, I would love you to prove me wrong.
It seems that each of the 8 asic chips has their own 3 or 4 phase vrm. Why would this be necessary? or even preferred? it seems like it would cut down on reliability and raise cost. If a 4 phase vrm can handle a 5870 chip at 150 watts why can't it handle all 8 asic chips at less than 100w
Why doesn't it look more like a video card anyways? Shouldn't the majority of the difference be less RAM, a usb port added and maybe a microprocessor to split the work among the 8 chips
what are the square blocks in the upper right? someone suggested capacitors. if so, why are there so many and such a big size. Its not like we are starting a big motor here.

Trust me, these default swaps will limit the risks
Wait, are there people mad now that they have found out if they buy an ASIC from BFL the product will be covered for life? I'm asking this question before I jump to conclusions. Oh btw Visiontek also has lifetime warranties... although I have never owned a product from that company. XFX is the shit! Just sayin'

sounds to good to be true
It does provide a use for all the trade-ins, maybe.
If they are going to get stuck with a bunch of old versions as people upgrade, they could use the traded in ones as replacement units for people who ship in an old model on warranty.

My point was is no company can be expected to fulfill a warranty service they have not done a risk calculation on. The only computer hardware company I have ever heard of selling a lifetime warranty is xfx, and this year they decided it was not sustainable without having a non-transferable clause. You think you can make a device more reliably than xfx? Or maybe you don't and you think oh well asic devices only cost us a few dollars to make. I remember another famous company that went this route, Oakley with their sunglasses. They also have discontinued their lifetime warranty.
There is no loophole. The warranty follows the board, so you can sell it and the warranty is still intact. Thus you don't need to register it... because we aren't warrantying the fan (at least not past 6 months or a year), there aren't really any seals we are going to be placing on the unit, either.
A reputable company that offers a lifetime warranty, does it because the benefits outweigh the costs. It prevents any unaccounted for loss by making as many loopholes in warranty terms needed, ie not transferable, mandatory registration, warranty seals etc. That's just the way business works. If you have been mining for a while you are likely to outweigh cost/benefit all the time. Some people pick newer 7000 cards for warranty. Others will pay less for a 4 year old 5800 card. Reference designs often take a premium as they seem more reliable. BFL has no way of estimated said costs yet, no way of making any educated guesses the product doesn't exist. Another BFL lie
I imagine if it fails in 5 years time, then they will more likely replace the unit of a newer model of similar speed than repair the old one ?
I will believe when I hear it from official BFL representative.

I heard about it from the Announcements area in the customers portal. I think that's where the magazine picked it from.
I do not think 'diaspora' means what you think it means.
Good to know they intend to stand by their product. Hopefully this rumor turns out to be true.
