You should edit the minirigs to "none APPEARED to have shipped" Since you have no proof for your statement.

This is a serious problem that may not have a fix.  I have a GPU that I still have running on SHA256 because it starts throwing massive errors if I try to use the same intensity on scrypt coins.  300MH vs 174KH running 16 vs 11 intensity.  Many of these GPUs have been running on hyperdrive for months on end, but until now they have not had to deal with the intensive memory load that your miner is throwing at them.  I'd bet your program hits GPU the same way P95 hits CPU... it stresses them to the point of failure not seen in normal/somewhat heavy operation.  With all the underclocking/overclocking/undervolting/overvolting I'd bet there are a lot of cards that appear to work fine yet are hiding a major problem. 

Memtest is a fairly intensive memory testing program, but it's not as intensive as P95.  I've seen many posts about people saying the P95 program was faulty cause it crashed their computer yet memtest said no problems.  Not once have those claims been proven out though, it's always ended up that P95 stressed something harder than memtest and found a problem that needed fixing.

I vaguely remember someone on the Mersenne forums having written a crude GPU program to simulate what memtest does... maybe you need to have people start looking into that.

Until then, I'd suggest you start having people answer a few basic questions to start the troubleshooting...

1) How old is your GPU?
2) Have you ever OC'd or declocked it?
3) What intensity settings have you run it at on other coins and for how long?
4) Have you ever over/under volted it?

I'd be willing to bet the answers to these 4 questions will start a pattern for those who have it working and those that don't.

You really need to learn how to read... he's saying they added 2 months onto the estimate GIVEN them, yet that was still not enough when compared to the ACTUAL delays incurred.  

You are half right.  The reality is both 50HZ and 60HZ are very hazardous to the human body.  The problem is that both are harmonics of the human heatbeat range (which is roughly 1-3Hz, not 60).  You'd need a much higher frequency to lessen the risk, ie: aircraft generators.  Most aircraft generators run at 400Hz which is too high a frequency to affect the heart.

I know well who he is, he had bad luck and wasn't smart enough to understand that's all it was.  I had several orphaned blocks during the time he was whining, but since *I* didn't have 9 in a row, he got pissy and cried scamcoin.  I noticed he's still mining though.   Hypocrits are SO fun to deal with

30 pounds of PLANT PORN!!!!!

I would bet the burn-in to be the most likely cause.  We'll be seeing it back on the network in a few days to a week.

What's the time limit on this guaranteed profit?  If the rate isn't up to $350 in a year, you going to payout $15,400 worth of BTC since you have offered a guaranteed $9030 profit?  If you want people to take a risk, you have to have risk yourself.

BTCGuild's high fees are for the PPS since you get paid for valid and invalid shares.  If you use the PPLNS the fees are ~1.2%

If you look at Deepbit's numbers, you will see Bitfury is added to theirs.  How else would a pool rated at 1.5TH be shown as 20% of the network?

Most likely a lot of equipment was brought online to test and then taken offline to ship.  Turning off hardware at this point in time would have such a minimal effect that it's make more sense to mine all the coins you could up to the last second.  This difficulty spike means earnings from 100TH dropped roughly 27% as compared to the previous difficulty.  That means it might have dropped 27.1 or 27.2% had it stayed online.  More profits lost in that day than saved by 'lower difficulty'.

I'd rather have to pull a couple of numbers out of thin air than see a program tell me that there will be $150billion worth of mining equipment on the network in a years time.  Anyone who reads these forums can see we've got a lot of pre-ordered ASICs primed to unload onto the network between now and Dec 1.  Over the last few increases we've seen 19%, then 36% then 29% then 32%.   Even if nobody shipped for the next 2 weeks, we're looking at a 40-45% jump in the next difficulty.  Maybe we'll get lucky and the pansies that demand refunds cause their potential RoI has just moved into the basement will stem the flood of products.

How about I send you 44 and you send me 49 when the rate hits $70?

Let's see... I donate to Red Cross... no financial gain.  I donate to MDA... no financial gain.  I donate to the MS society... no financial gain.

Donations are made for many reasons, to finance research and development it the main reason.  How efficient was the first GPU miner made for BTC?  I remember reading someone offered 10,000BTC to open source it.

Get off your high horse already, the hard part has been done, let the optimization work begin.

They only show up between the 1st and 2nd post on each page.  That means on average you should only see them every 20 posts.

Considering they are still operating on GPU power calculations, of course it LOOKS like a defecit.  Look at the bottom of the stats page:  "* Electricity consumption is estimated based on power consumption of 650 Watts per gigahash and electricity price of 15 cent per kilowatt hour. In reality some miners will be more or less efficient."

None of the ASIC are running at 650 watts of power per GH.

Nice calculator, a lot better put together than the x% jump forever the crowd now uses.  I think it need a little tweek though, I think the next 3-5 increases with be larger than the last and then start tapering off fairly quickly.  if possible add a % increase and # month increase to the calc.

I think you meant leader in $/GH.  500$/GH on the early 50BTC blades, $750/GH in May for USB.  Nobody knows how to ass-rape customers like AM.

It's not an opinion, it's fact.  But I guess the 6-8 other people now saying the same thing I did means nothing.
