Maybe those of us who have a vested interest in seeing BTC stay secured because we profit more from it's increased valuation vs fiat than some trivial daily profit.  Little late to the party? 

Wow.  So much fail all over the place it's not even funny.

Refer to this from last year:
http://gizmodo.com/5994446/digital-drills-the-monster-machines-that-mine-bitcoin

BFL purchasers of BFL minirigs were the biggest loosers (not winners per that Gizomodo article) for any non-blatant scamming company.

Avalon users didn't fare much better.  Flagship my ass.  Only if the flag shows somebody getting screwed over.

Damn you!  I thought the pool fees covered housecalls!

So going from losing 60% of your investment to only 38% is considered profitable 

It's less of a loss.

Sheesh, if you guys love trading so much just buy the BTC outright and trade it on BTCe - the chance for success is much higher there since at least you're not starting with a -40% handicap.

OK that wins the prize for the worst rig I have seen, and I've read every single post in this thread.  It looks like it fell though the ceiling or something yet somehow is stacked semi neatly.  Is that a wasp nest or beehive developing on it!?!

At least until difficulty levels off, the only people that should be buying mining eq are the whales that have "deals" with the manufacturers - at least from a profit perspective.

Anybody else buying equipment is securing the network but at a cost to their own profit margin.

You know some noobie will look at the last post (being yours) and will jump on it.  If you're going to make a sarcastic comment, please state so and use the roll eyes  emoticon 


TL:DR - it's a scam, don't buy

You need to do more reading.  If your computations made sense then everybody would buy the 300GH/s card for free money, then the difficulty would skyrocket and nobody would make money.   And that's exactly what's happened, except not with BFL hardware.  Considering BFL hasn't finished tapeout yet you're looking at a May/June release on those cards.

Let me fix that for you:
(Viability of mining) = [(Value of bitcoin)/(Network difficulty)]/(acquisition cost of mining equipment)

Right now all the SHA256 ASIC manufacturers are price gouging (whether they intend to or not).  When it came to GPUs the acquisition cost was more reasonable (except the recent LTC runup).

The fallacy is this: ROI is not getting your fiat back in the same amount but getting your BTC in the same amount.  The whole point of mining (other than to support the network and fulfill your nerdish fantasies) is to earn more BTC.  Not a single Jalapeno has earned more BTC than could have been used to purchase BTC directly.  I have a Day 1 SC Single I spent 208 BTC on and so far mined back less then 50 BTC - hoping for 55 before it's completely unprofitable.

The only known ASICs that have made true ROI are Avalon Batch 1&2 and early Jupiters.  Everything else was a gamble that never materialized.  Even a BFL gamble was better than some like bASIC who ran off with people's money (although not by much).

At this point it's hard to find any hardware that will ROI with current projections (only way for that to happen is from some companies in the competitor camp to have massive failures).  If BFL actually shipped units in 2012 instead of 2013 Avalon Batch 1 and 2 would have been failures.  Instead Avalon turned BFL's early guinea pigs into failures before themselves going rogue and mining on their customer's eq.

What do you mean by fake a robbery?  They'll say their prototypes were stolen?

You resurrected a 2 year old thread?  Honestly it's not worth the time or energy to get it working with so many proven motherboards out there.

Having said that, try increasing the PCI timer latency if it's available as a setting on your mobo.

It was 82F here in southern California today.... what is this cold weather you speak of?

It gets down to a chilly 58F at night.  I still have to run the AC during the day 

Doctor, Doctor, Doctor, Doctor, Doctor....


The fun lies in the fact you can actually play BF4 and not think damn, while I'm not mining I'm losing $0.03.  If you made $26k by buying the coins you probably won't care about missing out on 0.000196 coins lost to BF4 

As somebody who had 50GH/s of GPUs mining BTC offsite and having to drive 3x in one day for downtime - there's a lot to be said for sleeping soundly in your own bed and not restarting a rig.

Buying off eBay is fine.  The issue is can you run 3 cards next to each other.  If you live in a hot area you will either need a lot of airflow or have AC running.  If you're in a cold area then you just need to make sure you have a good power supply feeding the card.  Don't try to save $40 because any downtime and troubleshooting trying to figure out bad power will cost you $40 in the end anyways.

Yes, they decided it was important to establish their dominance in the cyptoworld rather than meet commitments made to their paying customers.  You see how that went.  I'm pretty sure the Monarch buyers who are repeat BFL customers is less than 20%.  Should the company survive to release another preorder beyond that I would be surprised if they had beyond 3% repeat buyers.

This coming from a Day 1 SC Single buyer (my single died after 6 days of use and had 14 days of RMA downtime).  Then again according to Josh I'm less than 1% of BFL's customer representation and my story is rare 

I wonder what to do with all these dead BFL PSUs.  The main cables are pretty beefy and probably have some good copper, but obviously the stuff "under the hood" is crap. I can't readily recycle them other than e-waste.  Anybody want 4 dead BFL PSUs?

Well nothing else failed before the end of 2013 but at 6PM on 1/2/14 another BFL SC Single PSU blew.  Cost me 2 days of mining since I was out of state.  Sucks I lost some PPC but I have to do this for science.

I now have a total of 4 failed BFL SC Single PSUs.  Fortunately I was planning for this and as soon as I got back I had a Seasonic waiting.  It's always scary to reconnect it to a good PSU after reading what lightfoot found, but none of my singles have been damaged irreparably (except the one that caught fire and burnt down even warping the case).

One thing I did note is all the failed ones have an orange sticker on them.  The yellow and green stickered ones haven't died yet.

Josh, any comments?  And before you mention the power on my end - in over 2 years of mining I've only had 1 6870 die (was bad from day one with crappy VRM) and recently I've seen a couple XFX 6870s have fan failures from 2.5 years of mining at 50% fan.  Nothing else has failed as much as these BFL products (admittedly I don't own any other ASICs).

Easier way is to make another account and just use BTCe codes to transfer over funds.

I remember when Ozcoin canceled PPS due mostly to a 9x followed by a 11x difficulty block.  On BTCGuild that would look like all 0's and maybe a 1 on the last shift
