Jesus man, what's wrong with people. You guys are wrapped a little too tight.

My major wasn't business, so I'm not real business savvy. I guess in my mind I'm thinking what does a company do to build something? They get a loan or investors. This is what I thought could be done. I admit, I'm not real keen on how companies operate but I do know a lot of them operate in the red for many years before turning a profit. I really did think you had the choice to sell from stock, I really didn't know you were forced into the pre-order game. I guess you can't just go to the bank and take a loan, right?

I stated earlier I wasn't very familiar with things outside the usa. Everyone is twisting my words. 30% of the usa has shit credit, yes, but FHA will give anyone a loan.  I also am talking about people who sit on 6k worth of mining equipment.

I like the way the rig rests on the brackets and doesn't use the front brackets for all the weight. At my work I see these huge servers being held up by just the front brackets and I can't believe they hold up, even though some of them sag in the back.

Not that much. Instead of well over, maybe medium rare. Specifically it would be $4195, which I'll mark up to $4200. You don't think that's a little high for 4.5TH/s delivered in mid September? And I'm not trying to argue, being serious. I guess prices and money is all ones perspective since everyone has their own value of money. I work hard long days for my money, so I value every dollar. I'm not cheap or frugal, but I do try to get the best price on something I can, if I can.

For  product with a life-span of a maximum 9 months, you can't afford to build it on stock. Look at the biostar 24GH board. They agree it was a trial run, but they came almost 1 year late. If it was an investment to be paid back, it's completely dead. On the other hand, there is a step between pre-orders and stock. It's called build-to-order .. similar with what you do in a restaurant  Sometimes the server takes your steak back because it's "not according to spec", but most of the time, they get it right and everyone is happy with the service.

The technology has to mature for this to happen .. or at least to have a couple of 28nm designs which are systematically improved, a ton of chips taken out the foundries every batch and with a demand not this high to eat all the output (decent 1000 units batch) in a month "on trust" (pre-orders). Eventually, we'll see custom configurations, unique setups which will closely meet the customer demands if they're going to be sold.

Here in NJ electricians are VERY expensive. I have a 100amp panel which is almost full and wanted to add a sub panel and a couple 240V circuits. I actually got two quotes. One was for $1200 and the other was $950. Installing new circuits you sometimes need to break down the sheet rock and do a lot of other things that just add to the cost. Once the electrician leaves then you need to do some sheet rock work, spackling, painting, etc. It adds up.

You guys should throw up your own forum. It is very easy to install since you already have your domain/website setup and really doesn't take anytime to mange or run it. Then you can really have a dedicated area for support relevant to your products instead of this one huge long thread that takes forever to find info and catch up on daily. Some of the most popular forum software is free. You guys could at least give that a try to get away from all the BS and trolls. And if you do get a forum up and running, one suggestion, don't turn into a moderator police officer. Some companies forums are horrible since they delete every post they disagree with and don't like. As long as the content is of a serious nature and respectful the post should stay. Good luck.

 

Yea, when do the SP50 pre-orders open ?

In the same boat, unfortunately SP-Tech wants to keep their sales model as pre-order only. Manufactures have the ability to change that and sell out of stock but choose not to because of the less risk to them. All the risk then shifts to the buyer and we see what happens. Please, don't get me wrong, and from previous posts, I think SP-Tech is probably one of the best makers of mining hardware around and I do look forward and eager to see what is on the horizon and future. I think they did the best they could with what they had and believe me, they didn't like the results and specs of their SP30 just as much as the customer's didn't.

Simply put, they are over built for a system with an expected lifetime of 6 - 9 months.

Yea, I'm confused about the pricing as well. I think they must pay a premium in raw materials or pay a shitload of money to get them built or something to have a premium price like that. They need to start ordering cheap ass China materials and build with that, lowering the overall price making the end product more appealing to potential customers. Yea, their rigs are rock solid and made like tanks but in my opinion maybe their purchasing decisions could be a little better.

^^^ TL;DR

Why don't you code it up and submit a pull request ?

The issue that I was raising is that temperatures in my DC are expected to fluctuate a lot (nearly as much as the outside temps) within a single day. Reconfiguring a miner for each time of the day is not a practical solution. Using settings that work in the worst case is a practical solution, but it's not optimal. I don't know that

I haven't seen any of my ASICs go above 85°C yet. Is performance on 200+V systems usually thermally throttled on the ASIC level or limited by PSU capacity, or is it limited by something else?

The temperature coefficient algorithm I suggested shouldn't require any additional restarts. You can think of the current firmware as being equivalent to using a tempco of 0%/°C for all of the variables. A non-zero value could be hard- or soft-coded into the firmware. If the tempco being used in the firmware is smaller than the physically accurate value, then the algorithm would converge on a configuration that is nearly optimal for the hottest conditions experienced but suboptimal for the coldest conditions experienced. If the tempco used is higher than the physically accurate value, then optimal for cold conditions but suboptimal for hot. I think it's unlikely that 0%/°C is the optimal value for all of those values, but it's possible that the optimal value is close enough to 0%/°C that it's not worth your time to code it. My quick-and-dirty estimate suggests it would, at least if either PSU heat rejection or thermal throttling is the bottleneck on performance.

You said that temperature didn't make a difference between 25°C and 35°C. I'm curious how you tested that.

P.S.: Can you guys take the rent vs. own argument to another thread, please?

wow, this looks almost like a setup from the "Soylent Green" or "Elysium"

You are indeed one ignorant person. You know shit about life, particularly outside the block you live in.

When you refer to a 3rd world country, take a note, that there are all beauties of modern civilization in there. Maybe even more, than in US. The key difference from developed countries is, that the middle class is almost disappeared in 3rd world countries and the rich are getting even more wealthy by abusing and enslaving of those in poverty. Believe me, you will not trust your vision, if you see those castles engraved in gold the rich people in developing countries live in. Their vehicles, also covered in gold or other precious metals. And army of slaves, behind them...

This is in Brazil, for example:


Regarding renting or buying a house, have you considered about the fact, that 30% of US population has a bad credit history or a bankruptcy, hence they can not get a mortgage loan? Educate yourself a bit, before making those hilarious statements...

I think the $290/mo was for the 2500W. After the upgrade announcement to 6Th/s the power consumption went up to 2700W so that's why the cost per month jumped to $310.

Yes, we had to be very quiet

Why don't you focus on the mining discussion and avoid brining your personal opinions into it regarding how someone tends to want to live. If you want to get into a conversation about personal choices in home ownership take it elsewhere.

I am not a part of GB, so just a matter of factual accuracy; wasn't the hosting deal $290 and not $310/mo, but maybe there are some savings in shipping or setup, so the 6 mo total does not change.
