The S3 at the time was an industry leader. They were at the forefront of new technology. The S5 is old tech compared to the competition.

They aren't however going to return a positive investment unless you have free power.

Lets be honest, the s5's are simply too little too late out of date technology. If underclocking them within the firmware was possible at 12v, they would have been a contender. Over the coming month with expected jumps of 20% or more, it's a loss leader. With no warranty, why would anyone consider this unless of course it was simply as a hobby, knowing you'd lose money anyway.

The problem here is Dogie claims to remain indifferent in how it claims to rate each company. No individual can remain completely unbiased when you are employed by one of them. If you go through many of his posts in other forums, they are usually one liners auto scripted, at times taken out of context. In bitmain forums, he rarely helps anyone to completion. Rather he hands off the problem to bitmain directly, wasting everyone's time.

On top of all this, he has hidden affiliate tags in his amazon links. If you have $1000 in your amazon shopping cart and click any of his links, even if you don't add it to your cart, Dogie will now get a cut of your purchase at checkout for the next 24 hours. Call it what you will, but I can't trust anyone who doesn't admit to this and at the same time, works for one of the major companies.

The final straw, he has insulted way too many people here. No company with any logic would hire him with his lack of community.

Do we independent or factual noise figures for the S5?

SP20's underclocked are rather quiet. I do agree the noise levels are high if you live near the equator.

I completely agree, Bitmain DID a great job on both previous designs and ROI figures. The games has changed and I still believe the U3, and C1 was the wrong direction. A waste of resources. Not speculating, however if you look at history and extrapolate, with advancements in technology we see some very large jumps in difficulty. Naturally, whilst some will ignore history and repeat the same mistakes, waiting for batch 2 (ie. the more bug free version), we shall see what the true difficulty numbers will be. Just saying don't jump in head first.

A great point on the connections. Where is the logic to continuing the same flawed design. The two other major manufacturers have pretty much the same single end connected design.

So making adjustments via a web interface is now classified as a "hack".
NO, NO IT'S NOT!
Having to get a power supply at 9V to underclock your S5's is a "hack".

Apparently that has changed to ...
"ANTMINER S5: The New Standard, 0.51J/G,"

So apparently it's now the "new standard" of what? something the SP20 has been capable of for months?

Lets be realistic, every new advancement in technology, history has shown at least a doubling in difficulty. There is no way an S5 will be able to compete even at half the price. Too little, too late.

It may have felt a lot like your emails to Bitmain since Dogie is a paid employee of bitmain to help english speaking customers. Supposedly. Most of his responses are simple scripted 1 liners. 

Worst still, the SP20 has been out for a while, the S5 is just being released. Bitmain wasted too many resources on the U3 and C1. Where bitmaintech used to be at the forefront, they are now on the back foot.

The S5 is coming out way too late to be a serious contender.

exactly and likewise here. I'm already matching that efficiency with SP20's and with new offerings due out shortly, bitmain are simply too far behind the curve now. With no underclocking directly available via standard 12v power supplies, it's a fail.

It will be interesting to see what Bitmain's poor choice in employees, ie dogie, will rate it. I'm sure being paid what influence his/hers/its rating.

Bitmain, I have purchased dozens of your products in the first half of the year, but your recent decisions including hiring dogie, sorry, you've made me look elsewhere.

and poor English support. The new SP is far more efficient and what Asicminer has coming.

I'd be interested in how often they are replacing burnt out power supplies and costs associated.

New hardware has been announced. Very few will buy old tech that will unprofitable in a month or two.

That is due to Dogie being a paid employee of bitmaintech. He/she will never say negative things about his/her meal ticket.

Common decency is back!

So I asked a legitimate question of which I the answer was given an answer, and you threaten me?

Part of the purpose of this forum is to prevent people being scammed. If you don't talk about these issues, people will fall for it as we've seen in many other posts.

Moving on, it was pointed out to be illegitimate of which I assume spondoolies have already contacted the authorities to take action against that company, therefore protecting their good name.

Also, what is the ambient temperature of where they are located?

If you still can't get it working correctly, best to contact bitmain support directly as it's a new unit.

If you go the bitmain route, stick with the S3's and your own power supplies. Decent ones like evga or corsair.

The spondoolies route, here is a recent video
